- We present three cases of eosinophilic granulomatosis with polyangiitis (EGPA) where patients experienced relapse of eosinophilic sinusitis without peripheral eosinophilia while on remission maintenance therapy with mepolizumab (MPZ), an anti-interleukin (IL)-5 monoclonal antibody. Despite the initial control of symptoms with high-dose prednisolone (PSL) and MPZ, patients experienced a relapse of nasal obstruction and eosinophilic infiltration in nasal mucosal biopsies. Notably, relapses occurred despite normal peripheral eosinophil counts, indicating the localized nature of eosinophilic inflammation. While IL-5 inhibitors effectively reduce peripheral blood eosinophils, eosinophilic sinusitis may persist due to local factors such as IL-4-mediated inflammation. IL-4 has been implicated in promoting eosinophil migration into nasal tissues, suggesting that IL-5 inhibitors alone may not sufficiently suppress eosinophilic infiltration in such cases. These findings highlight the importance of considering the possibility of eosinophilic sinusitis relapse in EGPA patients treated with IL-5 inhibitors and reduced glucocorticoid doses. Further research is warranted to elucidate the mechanisms underlying local eosinophilic inflammation and optimize treatment strategies for EGPA patients.2024年09月, Clinical rheumatology, 英語, 国際誌研究論文(学術雑誌)
- OBJECTIVES: The predictive validity of disease-specific quality of life (QOL) remains unknown in patients with systemic lupus erythematosus (SLE), although disease-specific measures are equally or more responsive to changes than generic QOL. We aimed to examine the predictive validity of the Lupus patient-reported outcome (PRO) for damage accrual. METHODS: Patients with SLE and ≥2 measurements over time were included in Japanese nationwide multicentre registry (LUNA). The Lupus PRO questionnaire contains both health-related (HR) and non-HR-QOL measures. Damage accrual was evaluated using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI). We examined the association between the Lupus-PRO score at baseline and longitudinal SDI scores using mixed-effects models adjusted for prognostic factors. RESULTS: Among 1295 patients, those with higher HR-QOL of Lupus PRO at baseline demonstrated a significantly lower increase in SDI (-0.005/year, 95% confidence interval [CI]: -0.007 to - 0.004, p < 0.001). According to the categorisation of HR-QOL based on tertile, a similar dose-dependent effect of HR-QOL on longitudinal SDI was identified (second vs first tertile category: -0.101/year, 95% CI: -0.172 to - 0.030; third tertile category: -0.211/year, 95% CI: -0.281 to - 0.142). Non-HR-QOL was not significantly associated with the SDI scores. Among the HR-QOL domains, cognition, procreation, and physical health were significantly associated with the total SDI scores over time. HR-QOL was associated with corticosteroid-dependent and -independent SDI scores. CONCLUSION: A higher HR-QOL of Lupus PRO was associated with a lower increase in SDI scores. Our findings imply the importance of disease-specific HR-QOL measurements in assessing prognosis.2024年06月, Rheumatology (Oxford, England), 英語, 国際誌研究論文(学術雑誌)
- We encountered a 64-year-old Japanese woman who developed subarachnoid hemorrhaging (SAH) with multiple cerebral artery stenoses during remission induction therapy for eosinophilic granulomatosis and polyangiitis (EGPA). The treatment involved intensified steroid pulse therapy and continued intravenous cyclophosphamide pulse therapy, which led to beneficial effects. Given the rarity of multiple EGPA-associated cerebral artery stenoses and SAH, it is crucial to differentiate them from other diseases. The mortality rate of EGPA complicated by intracranial hemorrhagic lesions, including SAH, is high. When headache is present at the onset of EGPA, the possibility of SAH must be considered.2024年05月, Internal medicine (Tokyo, Japan), 英語, 国内誌研究論文(学術雑誌)

- AIM: To investigate the association of large joint involvement (LJI) with disease activity and drug retention in patients with rheumatoid arthritis (RA) who started receiving a biological disease-modifying antirheumatic drug or Janus kinase inhibitor. METHODS: Patients with RA from a Japanese multicenter observational registry were enrolled. Our definition of large joints included the shoulder, elbow, hip, knee, and ankle joints. Linear mixed-effects models were used to examine changes in the clinical disease activity index (CDAI) score at Week 24 as the primary outcome, and drug retention rates were compared between patients with and without LJI using Cox proportional hazards models. We examined the potential effect modifications of changes in the CDAI by baseline characteristics. RESULTS: Overall, 2507 treatment courses from 1721 patients were included (LJI, 1744; no LJI, 763). Although LJI was associated with significantly higher changes in CDAI from baseline at Week 24 (difference in change in CDAI: -5.84 [-6.65 to -5.03], p < .001), CDAI was significantly higher in patients with LJI over time. Retention rates were similar in both groups. The association of LJI with changes in disease activity was more prominent in patients with a short disease duration, negative anti-citrullinated peptide antibodies, and interleukin-6 receptor inhibitor (IL-6Ri) use. CONCLUSION: Although LJI was associated with a greater reduction in disease activity from baseline, higher disease activity at baseline was not offset over time in patients with LJI, demonstrating that LJI is an unfavorable predictor. An early treat-to-target strategy using an IL-6Ri may be beneficial for patients with LJI.2024年03月, International journal of rheumatic diseases, 27(3) (3), e15097, 英語, 国際誌研究論文(学術雑誌)
- OBJECTIVES: This multicentre, retrospective study aimed to compare retention and reasons for discontinuation between Janus kinase inhibitors (JAKi) and biologic disease-modifying antirheumatic drugs in patients with elderly-onset rheumatoid arthritis (EORA). METHODS: Patients with RA enrolled in a Japanese multicentre observational registry between 2015 and 2022 were included. EORA was defined as RA with onset at 60 or over. To adjust confounding factors by indication for initiation of tumor necrosis factor inhibitors (TNFi), interleukin-6 inhibitors (IL-6i), cytotoxic T-lymphocyte associated antigen 4 immunoglobulin (CTLA4-Ig) blockers, or JAKi, a propensity score based on baseline characteristics was used to compare drug retention. To assess the reasons for discontinuation, retention rates for ineffectiveness, adverse events, and remission were analyzed as secondary outcomes. RESULTS: A total of 572 patients with 835 treatment courses were identified (314 TNFi, 175 IL-6i, 228 CTLA4-Ig, and 118 JAKi). After adjusting for differences in baseline characteristics, drug retention was significantly higher for IL-6i (HR = 0.38, 95%CI = 0.27-0.55, p< 0.01) as compared with TNFi. Discontinuation due to lack of effectiveness was lower with the JAKi (HR = 0.38, 95%CI = 0.22-0.66, p< 0.01) and the IL-6i (HR = 0.29, 95%CI = 0.19-0.46, p< 0.01) as compared with the TNFi although the CTLA4-Ig had a similar HR to TNFi. The adjusted incidence of discontinuation due to adverse event was higher in the JAKi (HR = 2.86, 95%CI = 1.46-5.59, p< 0.01) than the TNFi. CONCLUSIONS: In EORA patients, IL-6i and JAKi had longer retention and less discontinuation due to ineffectiveness than TNFi. The potential risks of JAKi should be approached with an individualized perspective.2024年02月, Rheumatology (Oxford, England), 英語, 国際誌研究論文(学術雑誌)

- OBJECTIVES: To examine the effectiveness and drug tolerability of biological disease-modifying antirheumatic drugs (bDMARDs) and Janus kinase inhibitor (JAKi) monotherapy in patients with rheumatoid arthritis (RA) in a multicentre cohort study. METHODS: Patients with RA initiated with bDMARD/JAKi monotherapy without conventional synthetic DMARDs were included. Monotherapy regimens were categorised as interleukin-6 receptor inhibitors (IL-6Ri), cytotoxic T-lymphocyte-associated protein 4 immunoglobulin (CTLA4Ig), JAKi, or tumour necrosis factor inhibitors (TNFi). Multiple propensity score-based inverse probability weighting (IPW) was used to reduce selection bias. Linear mixed-effect models with IPW were used to examine changes in the disease activity score in 28 joints (DAS28)-erythrocyte sedimentation rate (ESR) at 24 weeks, and drug retention was compared among monotherapy using IPW Cox proportional hazards models. RESULTS: A total of 849 treatment courses from 635 patients were included (IL-6Ri, 218; CTLA4Ig, 183; JAKi, 92; TNFi, 356). The difference in change in DAS28-ESR at week 24 as the primary outcome was -0.93 (95% CI: -1.20 to -0.66) lower in the IL-6Ri group than TNFi, while that of CTLA4Ig and JAKi was similar with that of TNFi (-0.20 [-0.48 to 0.08], -0.25 [-0.67 to 0.16], respectively). IL-6Ri use was associated with significantly lower overall drug discontinuation than TNFi use (hazard ratio = 0.55 [0.39-0.78], P = 0.001). Similar retention rates were identified among CTLA4Ig and JAKi compared to TNFi. CONCLUSION: In the analysis with IPW to reduce selection bias, IL-6Ri monotherapy was superior to TNFi monotherapy in terms of effectiveness and drug retention. No significant differences were identified between CTLA4Ig, JAKi, and TNFi monotherapy.2023年11月, Rheumatology (Oxford, England), 英語, 国際誌研究論文(学術雑誌)
- OBJECTIVE: This multicentre, retrospective study compared the efficacy and safety of tofacitinib, baricitinib, peficitinib and upadacitinib in real-world clinical settings after minimizing selection bias and adjusting the confounding patient characteristics. METHOD: The 622 patients were selected from the ANSWER cohort database and treated with tofacitinib (TOF), baricitinib (BAR), peficitinib (PEF) or upadacitinib (UPA). The patient's background was matched using propensity score-based inverse probability of treatment weighting (IPTW) among four treatment groups. The values of Clinical Disease Activity Index (CDAI), C-reactive protein (CRP), and modified Health Assessment Questionnaire (mHAQ) after drug initiation and the remission or low disease activity (LDA) rates of CDAI at 6 months after drug initiation were compared among the four groups. Further, the predictive factor for TOF and BAR efficacy was analysed. RESULTS: The retention and discontinuation rates until 6 months after drug initiations were not significantly different among the four JAK inhibitors treatment groups. Mean CDAI value, CDAI remission rate, and CDAI-LDA rate at 6 months after drug initiation were not significantly different among treatment groups. Baseline CDAI (TOFA: OR 1.09, P < 0.001; BARI: OR 1.07, P < 0.001), baseline CRP (TOFA: OR 1.32, P = 0.049), baseline glucocorticoid dose (BARI: OR 1.18, 95% CI 1.01-1.38, P = 0.035), a number of previous biological or targeted synthetic disease-modifying antirheumatic drugs (biological/targeted synthetic DMARDs) (BARI: OR 1.36, P = 0.004) were predictive factors for resistance to CDAI-LDA achievement to JAK inhibitor treatment. CONCLUSION: The efficacy and safety of TOF, BAR, PEF and UPA were not significantly different for the treatment of patients with rheumatoid arthritis.2023年11月, Rheumatology (Oxford, England), 英語, 国際誌研究論文(学術雑誌)
- BACKGROUND: β2-glycoprotein I (β2GPI) complexed with human leukocyte antigen DR (β2GPI/HLA-DR) was found to be a major autoantibody target in antiphospholipid syndrome (APS). This study aimed to reveal the association between anti-β2GPI/HLA-DR antibodies and vascular thromboses in women with systemic rheumatic diseases. METHODS: We conducted a retrospective longitudinal study. We measured anti-β2GPI/HLA-DR antibodies and compared them with anti-phospholipid antibody (aPL) profiles and the adjusted global antiphospholipid syndrome score (aGAPSS). Using receiver operating characteristic (ROC) analysis, we determined the best cut-off value for arterial thrombosis. We also evaluated the validity of anti-β2GPI/HLA-DR antibodies by adding to conventional cardiovascular risk factors in multivariate logistic analysis. RESULTS: We evaluated 704 patients, including 66 (obstetric or thrombotic) APS, 13 primary APS, and 78 asymptomatic aPL carriers. Seventy-seven patients had a history of arterial thrombosis, and 14 patients had both arterial and venous thrombosis. These 14 patients, as well as patients with aGAPSS > 10 or triple-positive aPL profiles, displayed high anti-β2GPI/HLA-DR antibody titers. The ROC curve showed a sensitivity, specificity, and area under the curve (AUC) for arterial thrombosis of 33.8%, 91.4%, and 0.6009, respectively, with a cut-off value of 172.359 U/mL. The anti-β2GPI/HLA-DR antibody positivity using this cut-off value yielded an odds ratio of 5.13 (95%CI: 2.85-9.24), significantly improving the AUC from 0.677 to 0.730. CONCLUSION: Anti-β2GPI/HLA-DR antibodies are associated with arterial thrombosis in female patients with systemic rheumatic diseases.2023年10月, Arthritis research & therapy, 25(1) (1), 195 - 195, 英語, 国際誌研究論文(学術雑誌)
- OBJECTIVES: To investigate if disease activity among elderly RA patients over 75 years has changed over time in the real-world clinical setting. METHODS: Data from an observational multicentre registry of RA patients in Japan were analyzed. The primary outcome was to evaluate the changes in the proportion of very elderly RA patients (over 75 years) who achieved remission and low disease activity, from 2014 to 2021. The secondary outcome was to identify factors associated with remission and low disease activity by comparing demographic and clinical characteristics among the patients who had a study visit within the study period, using multivariate logistic regression. RESULTS: A total of 32 161 patient visits were identified from 2014 to 2021. The proportion of patients over 75 years increased from 16.5% to 26.9%, with biologics and targeted-synthetic disease modifying anti-rheumatic drugs (b/tsDMARDs) usage increasing and glucocorticoids usage decreasing, while conventional-synthetic DMARDs usage remained relatively stable. The proportion of RA patients over 75 years achieving remission and low disease activity significantly increased from 62.2% to 78.2% (p for trend < 0.001). A negative factor associated with achieving remission and low disease activity was glucocorticoid usage, seropositivity, and history of previous b/tsDMARDs use while MTX usage was associated positively, independent of other predictors. CONCLUSIONS: In our cohort, disease activity among very elderly RA patients has improved over time. The study suggests the importance of using a treat-to-target approach in very elderly RA patients to improve clinical outcomes.2023年10月, Rheumatology (Oxford, England), 英語, 国際誌研究論文(学術雑誌)
- OBJECTIVES: Exosomes are potent vehicles for intercellular communication. Rheumatoid arthritis (RA) is a chronic systemic disease of unknown etiology. Local administration of miR-124 precursor to rats with adjuvant-induced arthritis suppresses systemic arthritis and bone destruction. Thus, exosomes may be involved in this disease. We aimed to determine the role of exosomes in the pathology of RA. METHODS: Fibroblast-like synoviocytes (FLS) were collected from patients with RA and osteoarthritis (OA). miR-124-3p mimic was transfected into the RA FLS (RA miR-124 FLS). Exosomes were collected from the culture medium by ultracentrifugation. Macrophages were produced from THP-1 cells. MicroRNAs in the exosomes were analyzed using real-time PCR. Proteomics analysis was performed using nanoscale liquid chromatography-tandem mass spectrometry. Macrophage migration was evaluated using a Transwell migration assay. SiRNA was used to knockdown proteins of interest. RESULTS: MicroRNAs in the RA FLS, RA miR-124 FLS, and OA FLS exosomes were similar. Proteomics analysis revealed that pentraxin 3 (PTX3) levels were higher in RA FLS exosomes than in RA miR-124 FLS and OA FLS exosomes, and proteasome 20S subunit beta 5 (PSMB5) levels were lower in RA FLS exosomes than in RA miR-124 FLS and OA FLS exosomes. The RA FLS exosomes promoted and the RA miR-124 FLS exosomes suppressed macrophage migration. PTX3-silenced RA FLS exosomes suppressed and PSMB5-silenced OA FLS exosomes promoted macrophage migration. CONCLUSIONS: RA FLS exosomes promote macrophage migration via PTX3 and PSMB5, and miR-124-3p suppresses this migration.2023年04月, Heliyon, 9(4) (4), e14986, 英語, 国際誌研究論文(学術雑誌)

- BACKGROUND: The serum creatinine (SCr) concentration in neonates is generally high for its body size, compared to those of infants. The aim of the present study was to investigate the effect of maternal SCr on neonatal SCr through measurements of prenatal maternal SCr and neonatal SCr from birth to postnatal Day 5. In addition, postnatal changes in SCr were compared between term and preterm infants, given that few studies have addressed this topic. METHODS: The retrospective study subjects were 151 neonates whose Scr was measured consecutively from birth to postnatal Day 5 and 124 mothers whose SCr was measured prenatally. RESULTS: There were significant correlations between maternal SCr and neonatal SCr at birth (r = 0.858, p < 0.001) and on postnatal Day 1 (r = 0.235, p < 0. 001). The SCr of term infants (median 0.69 mg/dL, range 0.54 - 0.96 mg/ dL) were higher than those of preterm infants (median 0.63 mg/dL, range 0.43 - 1.23 mg/dL, p < 0.001) at birth; however, these values were reversed on postnatal Day 1 (Term: median 0.75 mg/dL, range 0.51 - 1.13 mg/dL, Pre-term: median 0.88 mg/dL, range 0.56 - 1.25 mg/dL, p < 0.001). There were differences in the timing of reaching to peak SCr between preterm and term neonates. In addition, birth weight might affect SCr concentrations after birth. CONCLUSIONS: The results of this study suggest that neonatal SCr is influenced by maternal SCr, although the effect disappears by postnatal Day 2. Moreover, glomerular filtration rate differs between term and preterm infants.2023年03月, Clinical laboratory, 69(3) (3), 英語, 国際誌研究論文(学術雑誌)
- PURPOSE: To achieve a better patient experience with self-injection, an assessment of potential demographic, physical, and psychological barriers is necessary. The aim of this study was to examine the demographic, physical, and psychological characteristics associated with the experiences of self-injection in patients with rheumatoid arthritis (RA). PATIENTS AND METHODS: In this study, overall patient experience with subcutaneous self-injection was assessed using the Self-Injection Assessment Questionnaire. Upper limb function was assessed using the three domains of the Health Assessment Questionnaire associated with upper extremity disability (dressing and grooming, eating, and grip). Structural equation modeling was used to estimate the association between the demographic and clinical characteristics of patients with RA and their experiences with self-injection in the theoretical model. RESULTS: Data from 83 patients with RA were analyzed. Compared with younger patients, elderly patients were more likely to experience lower self-confidence, self-image, and ease of use. Female patients had lower ease of use than male patients. In terms of upper limb function, patients with more difficulty in performing activities of daily living were more likely to have a lower self-image. Self-injection perceptions before learning the method of injection, such as fear of needles and anxiety about self-injection, were associated with post-injection feelings, injection site reactions, self-confidence, and ease of use. CONCLUSION: To optimize patients' experiences with self-injection, healthcare workers should assess each patient's age, sex, upper limb function, and pre-self-injection perceptions as demographic, physical, and psychological barriers.2023年, Patient preference and adherence, 17, 1551 - 1559, 英語, 国際誌研究論文(学術雑誌)
- Objectives: Rapid plasma reagin (RPR) and Treponema pallidum (TP) antibody test kits are often used to diagnose syphilis, although the relationship between their measured values is unclear. We aimed to reveal the relevance of these kits' results. Design and methods: In all, 143 sera from 110 patients were tested using 12 TP kits and 5 RPR kits and the results compared. Results: The specificity and sensitivity of RPR kits were 81-96% and 95-100%, respectively. The correlation coefficients (0.849-0.934) considerably differed between the manual RPR card test and latex agglutination (LA) assay kits. The following sensitivities were obtained: 82-91% for TP fluorescent treponemal antibody absorption assay (FTA-ABS), TP hemagglutination assay (HA), and TP particle agglutination assay (PA); 94-95% for TP LAs; and 92-100% for chemiluminescent immunoassay (CLIA), chemiluminescent enzyme immunoassay (CLEIA), and immunochromatography assay (IC). Correlation coefficients between TP kits were 0.753-0.974, and the measured values varied. Changes in RPR and quantifiable TP kits were the same for patients with reinfected syphilis and with syphilis under treatment. Conclusions: RPR tests had lower specificity than TP antibody tests. RPR card test and RPR LAs had similar specificity and sensitivity, but their measured values were different. RPR should be measured using automatic RPR LA without setting the upper limit of the reported value. RPR LA should also be standardized. The sensitivity of TP antibody was better in CLIA, CLEIA, and IC than in FTA-ABS, HA, PA, and LA. Therefore, TP antibody kits should be standardized and quantified.2022年11月, Practical laboratory medicine, 32, e00302, 英語, 国際誌研究論文(学術雑誌)

- Continuous appearance of SARS-CoV-2 variants and mass vaccination have been intricately influencing on the COVID-19 situation. To elucidate the current status in Japan, we analyzed totally 2,000 sera in August (n = 1,000) and December (n = 1,000) 2021 collected from individuals who underwent a health check-up. The anti-N seropositive rate were 2.1% and 3.9% in August and December 2021, respectively, demonstrating a Delta variant endemic during that time; it was approximately twofold higher than the rate based on the PCR-based diagnosis. The anti-S seropositive rate was 38.7% in August and it reached 90.8% in December, in concordance with the vaccination rate in Japan. In the December cohort, 78.7% of the sera showed neutralizing activity against the Delta variant, whereas that against the Omicron was much lower at 36.6%. These analyses revealed that effective immunity against the Delta variant was established in December 2021, however, prompt three-dose vaccination is needed to overcome Omicron's outbreak.2022年, PloS one, 17(4) (4), e0266270, 英語, 国際誌研究論文(学術雑誌)
- Serum Cytokine Profiles of Rapid Recovery Patients with COVID-19: Series of 6 Cases.COVID-19 patients reveal various clinical manifestations; however, the specific mechanisms and factors contributing to rapid recovery remain unclear. We performed serum cytokine profiling using a bead-based immunoassay in six COVID-19 patients with mild symptoms who experienced rapid recovery. All patients had fever that resolved within 4 days. During the study, the interferon gamma-related protein 10 (IP-10) level rapidly increased initially, and then rapidly decreased in all six patients. Similarly, the interferon (IFN)-λ 2/3 levels rapidly increased initially, and then decreased in five of the six patients. IP-10 and IFN-λ2/3 may play a key role in the rapid recovery of mild COVID-19.2021年10月, The Kobe journal of medical sciences, 67(2) (2), E55-E60, 英語, 国内誌研究論文(学術雑誌)

Abstract The situation of the COVID-19 pandemic in Japan is drastically changing in the 2nd year, 2021, due to the appearance of SARS-CoV-2 variants of concern and the roll-out of mass vaccination. In addition to PCR diagnosis, periodic seroepidemiologic surveillance is important to analyze the epidemic situation. In this study, we analyzed the rate of seropositivity for the SARS-CoV-2 N and S antigens in Hyogo prefecture, Japan in August 2021. Sera collected from people who received a health check-up in a clinic of the Hyogo Prefecture Health Promotion Association were subjected to analysis of reactivity to the SARS-CoV-2 N and S antigens by electrochemiluminescence immunoassay (ECLIA) and enzyme-linked immunosorbent assay (ELISA), respectively. For a total 1,000 sera, the positive rates to N and S antigens were 2.1% and 38.7%, respectively. The infectious rate estimated by serological analysis based on the presence of the anti-N antibody was 2.5-fold higher than the value reported based on PCR-based analysis, and it increased five-fold compared to the rate determined by our previous seroepidemiologic study in October, 2020. The anti-S positive rate was almost consistent with the vaccination rate in this area. The observed high anti-S antibody level in the seropositive population may indicate that the mass vaccination in Japan is being performed smoothly at this time point, although the infectious rate has also increased. - 2021年09月, International journal of laboratory hematology, 英語, 国際誌

- Resolvins, are specialized pro-resolving mediators (SPMs) derived from n-3 polyunsaturated fatty acids. They contribute actively to the resolution of inflammation, but little is known concerning their role in chronic inflammation, such as in rheumatoid arthritis (RA). Here, we performed lipid mediator (LM) profiling in tissues from the paws of SKG arthritic mice using lipid chromatography (LC)/mass spectrometry (MS)/MS-based LM metabololipidomics. We found elevated levels of SPMs including resolvin D5 (RvD5) in these tissues. Moreover, RvD5 levels were significantly correlated with arthritis disease activity. From experiments to assess the role of RvD5 in the pathology of RA, we concluded that RvD5 suppressed Th17 cell differentiation and facilitated regulatory T cell differentiation, as well as inhibiting CD4+ T cell proliferation. Furthermore, RvD5 attenuated osteoclast differentiation and interfered with osteoclastogenesis. Targeting the resolution of inflammation could be promising as a novel treatment for RA.2021年08月, Scientific reports, 11(1) (1), 17312 - 17312, 英語, 国際誌研究論文(学術雑誌)
- Background: Antibody production is one of the primary mechanisms for recovery from coronavirus disease 2019 (COVID-19). It is speculated that massive clonal expansion of B cells, which can produce clinically meaningful neutralizing antibodies, occurs in patients who recover on the timing of acquiring adaptive immunity. Methods: To evaluate fluctuations in clonal B cells and the size of the clones, we chronologically assessed the B-cell receptor (BCR) repertoire in three patients with COVID-19 who recovered around 10 days after symptom onset. Results: We focused on the three dominant clonotypes (top 3) in each individual. The percentage frequencies of the top 3 clonotypes increased rapidly and accounted for 27.8 % on day 9 in patient 1, 10.4 % on day 12 in patient 2, and 10.8 % on day 11 in patient 3, respectively. The frequencies of these top 3 clonotypes rapidly decreased as the patients' clinical symptoms improved. Furthermore, BCR network analysis revealed that accumulation of clusters composed of similar complementarity-determining region 3 (CDR3) sequences were rapidly formed, grew, and reached their maximum size around 10 days after symptom onset. Conclusions: BCR repertoire analysis revealed that a massive surge of some unique BCRs occurs during the acquisition of adaptive immunity and recovery. The peaks were more prominent than expected. These results provide insight into the important role of BCRs in the recovery from COVID-19 and raise the possibility of developing neutralizing antibodies as COVID-19 immunotherapy.2021年08月, Heliyon, 7(8) (8), e07748, 英語, 国際誌研究論文(学術雑誌)
- OBJECTIVES: We aimed to identify disease-specific surface proteins on extracellular vesicles (EVs) as novel serum biomarkers of polymyositis and dermatomyositis (PM/DM). METHODS: We performed liquid chromatography-tandem mass spectrometry (LC/MS) on purified EVs from sera of 10 PM/DM, 23 patients with other autoimmune diseases and 10 healthy controls (HC). We identified membrane proteins preferentially present in EVs of PM/DM patients by bioinformatics and biostatistical analyses. We developed EV sandwich ELISA for directly detecting serum EVs expressing disease-specific membrane proteins and evaluated their clinical utility using sera of 54 PM/DM, 24 rheumatoid arthritis (RA), 20 systemic lupus erythematosus (SLE), 13 systemic sclerosis, 25 Duchenne and Becker muscular dystrophy (DMD/BMD) patients, and 36 HC. RESULTS: LC/MS analysis identified 1,220 proteins in serum EVs. Of these, Plexin D1 was enriched in those from PM/DM patients relative to HC or patients without PM/DM. Using a specific EV sandwich ELISA, we found that levels of Plexin D1-positive EVs (Plexin D1+ EVs) in serum were significantly greater in PM/DM patients than in HC, RA or SLE, or DMD/BMD patients. Serum levels of Plexin D1+ EVs were greater in those PM/DM patients with muscle pain or weakness. Serum levels of Plexin D1+ EVs were significantly correlated with levels of aldolase (rs=0.481), white blood cells (rs=0.381), neutrophils (rs=0.450), and platelets (rs=0.408) in PM/DM patients. Finally, serum levels of Plexin D1+ EVs decreased significantly in patients with PM/DM in clinical remission after treatment. CONCLUSION: We have identified levels of circulating Plexin D1+ EVs as a novel serum biomarker for PM/DM.2021年07月, Rheumatology (Oxford, England), 61(4) (4), 1669 - 1679, 英語, 国際誌研究論文(学術雑誌)
- We compared the prophylactic effect of trimethoprim-sulfamethoxazole (TMP-SMX) with atovaquone for pneumocystis pneumonia (PCP) in patients with connective tissue diseases (CTDs) receiving high-dose glucocorticoids. Patients with CTDs aged ≥ 18 years who were treated with a prolonged course (≥ 4 weeks) of glucocorticoids (≥ 20 mg/day prednisone) in a Japanese tertiary center between 2013 and 2017 were included. The patients were categorized into two groups: TMP-SMX and atovaquone group. Adjusted cumulative incidence of PCP was compared between the two groups after propensity score weighting for differences in confounding factors. A total of 480 patients with a prolonged high-dose glucocorticoid treatment were identified. Out of 383 patients with TMP-SMX prophylaxis, 102 (26.8%) patients experienced adverse events leading to discontinuation within 4 weeks of initiation, while no patient in the atovaquone discontinued the therapy. Two hundred eighty-one patients received TMP-SMX, while 107 received atovaquone for PCP prophylaxis. During a total of 397.0 person-years, 7 PCP cases (2 in the TMP-SMX, 5 in the atovaquone) occurred with a mortality rate of 54.5%. After adjusting for differences in baseline characteristics, the adjusted cumulative incidence of PCP was similar between the two group (HR 0.97, 95% CI 0.19-5.09, p = 0.97). Prophylactic effects for PCP in CTDs patients receiving prolonged high-dose glucocorticoids were similar between TMP-SMX and atovaquone. Atovaquone was well-tolerated with no side effects.2021年07月, Rheumatology international, 英語, 国際誌研究論文(学術雑誌)
- The t(1;11)(p32;q23) translocation is a rare but recurrent cytogenetic aberration in acute myeloid leukemia (AML) and B-cell acute lymphoblastic leukemia (B-ALL). This translocation was initially shown to form a fusion gene between KMT2A exon 8 at 11q23 and EPS15 exon 2 at 1p32 in AML. Activating mutations of FLT3 are frequently found in AML but are very rare in ALL. Here, we describe a 75-year-old woman who was diagnosed with B-ALL since her bone marrow was made up of 98.2% lymphoblasts. These blasts were positive for CD19, CD22, CD79a, CD13, and CD33 but negative for CD10 and myeloperoxidase. The karyotype by G-banding and spectral karyotyping was 46,XX,t(1;11)(p32;q23). Expression of KMT2A/EPS15 and reciprocal EPS15/KMT2A fusion transcripts were shown: KMT2A exon 8 was in-frame fused to EPS15 exon 12, indicating that this fusion transcript was a novel type. Considering three reported B-ALL cases, EPS15 breakpoints were markedly different between AML (exon 2) and B-ALL (exons 10-12). Furthermore, an uncommon type of FLT3 mutation in the juxtamembrane domain was detected: in-frame 4-bp deletion and 10-bp insertion. Accordingly, our results indicate that the novel type of KMT2A/EPS15 fusion transcript and FLT3 mutation may cooperate in the pathogenesis of adult B-ALL as class II and class I mutations, respectively.2021年06月, Cancer genetics, 254-255, 92 - 97, 英語, 国際誌研究論文(学術雑誌)
- BACKGROUND: Systemic sclerosis (SSc) is a chronic autoimmune-mediated connective tissue disorder. Although the etiology of the disease remains undetermined, SSc is characterized by fibrosis and proliferative vascular lesions of the skin and internal organs. SSc involves the gastrointestinal tract in more than 90 % of patients. Soluble guanylate cyclase (sGC) stimulator is used to treat pulmonary artery hypertension (PAH) and has been shown to inhibit experimental skin fibrosis. METHODS: Female C57BL/6J mice were treated with BLM or normal saline by subcutaneous implantation of osmotic minipump. These mice were sacrificed on day 28 or day 42. Gastrointestinal pathologies were examined by Masson Trichrome staining. The expression of fibrosis-related genes in gastrointestinal tract was analyzed by real-time PCR, and the levels of collagen in the tissue were measured by Sircol collagen assay. To evaluate peristaltic movement, the small intestinal transport (ITR%) was calculated as [dyeing distance × (duodenum - appendix)] - 1 × 100 (%). We treated BLM-treated mice with sGC stimulator or DMSO orally and analyzed them on day 42. RESULTS: Histological examination revealed that fibrosis from lamina propria to muscularis mucosa in the esophagus was significantly increased in BLM-treated mice, suggesting that BLM induces esophageal hyperproliferative and prefibrotic response in C57BL/6J mice. In addition, the gene expression levels of Col3a1, CCN2, MMP-2, MMP-9, TIMP-1, and TIMP-2 in the esophagus were significantly increased in BLM-treated mice. More severe hyperproliferative and prefibrotic response was observed in the mice sacrificed on day 42 than the mice sacrificed on day 28. The ITR% was found to be significantly lower in BLM-treated mice, suggesting that gastrointestinal peristaltic movement was reduced in BLM-treated mice. Furthermore, we demonstrated that sGC stimulator treatment significantly reduced hyperproliferative and prefibrotic response of esophagus and intestine in BLM-treated mice, by histological examination and Sircol collagen assay. CONCLUSIONS: These findings suggest that BLM induces gastrointestinal hyperproliferative and prefibrotic response in C57BL/6J mice, and treatment with sGC stimulator improves the BLM-induced gastrointestinal lesion.2021年05月, Arthritis research & therapy, 23(1) (1), 133 - 133, 英語, 国際誌研究論文(学術雑誌)
- BACKGROUND: This multi-center, retrospective study aimed to clarify retention rates and reasons for discontinuation of either tumor necrosis factor inhibitors (TNFi) or interleukin-6 inhibitors (IL-6i) in patients with elderly-onset rheumatoid arthritis (EORA). METHODS: Patients with rheumatoid arthritis (RA) enrolled in a Japanese multicenter observational registry between 2011 and 2020 were included. EORA was defined as RA with onset at 60 or over. To adjust confounding by indication for treatment with TNFi or IL-6i, a propensity score based on multiple baseline characteristics variables was used to compare the drug retention and causes for discontinuation between TNFi and IL-6i. Adjusted cumulative incidence of drug discontinuation for each reason was compared between the two groups using the Fine-Gray model. RESULTS: Among a total of 9,550 patients in the registry, 674 TNFi and 297 IL-6i initiators with EORA were identified. Age, the proportion of females, disease duration, and baseline disease activity at the time of TNFi or IL-6i initiation were similar between the two groups. After adjusting for differences in baseline characteristics between the two groups, overall drug discontinuation was significantly lower in the IL-6i as compared to the TNFi (HR = 0.71, 95%CI = 0.59-0.86, p < 0.001). The adjusted cumulative incidence of discontinuation due to lack of effectiveness was lower with the IL-6i (HR = 0.46, 95%CI = 0.33-0.63, p < 0.001) while those due to adverse events (HR = 0.82, 95%CI = 0.56-1.18, p = 0.28) or achievement of clinical remission (HR = 1.09, 95%CI = 0.62-1.91, p = 0.76) were similar between the two groups. CONCLUSIONS: In EORA patients initiating a TNFi or IL-6i, significantly higher drug retention was observed with IL-6i. Discontinuation due to lack of effectiveness was significantly less frequent in IL-6i while discontinuations due to adverse event or achievement of clinical remission were similar between the two groups.2021年04月, Arthritis research & therapy, 23(1) (1), 116 - 116, 英語, 国際誌研究論文(学術雑誌)

- Neonatal jaundice has been suggested as a perinatal risk factor for autism spectrum disorder (ASD). We examined UGT1A1 polymorphisms to assess the potential of neonatal jaundice as a risk factor for ASD in children by using DNA extracted from preserved umbilical cord. In total, 79 children with ASD were genotyped for UGT1A1*28 (c.-41-40dup), UGT1A1*6 (c.211 G > A), and UGT1A1*27 (c.686 C > A). The allele frequency of UGT1A1*6 (OR = 1.34, p = 0.26) and UGT1A1*28 (OR = 0.80, p = 0.54) and the prevalence of UGT1A1*28/*6 diplotypes did not differ significantly from those in the control population. No UGT1A1*27 allele was detected in the subjects. ASD symptom assessment scores were not associated with UGT1A1*28/*6/*27 genotypes or UGT1A1*28/*6 diplotypes. These results suggest that neonatal jaundice is not significantly associated with ASD.2021年03月, Journal of autism and developmental disorders, 52(2) (2), 483 - 489, 英語, 国際誌研究論文(学術雑誌)
- ABSTRACT: Previous studies from various countries have reported anti-dense fine speckled pattern (DFS)70 antibody prevalence but few studies have been from Asia. We investigated the prevalence of anti-DFS70 autoantibodies in a Japanese cohort of healthy individuals (HI) and patients with antinuclear antibody-associated autoimmune rheumatic diseases (AARD).Enzyme-linked immunosorbent assay and indirect immunofluorescence were performed using samples from 250 HI and 276 AARD patients.The overall anti-DFS70 antibody prevalence in HI was 16.4%, with 12.8% for males and 20.0% for females (sex difference; P = .12). In AARD patients, the anti-DFS70 antibody prevalence in systemic lupus erythematosus, mixed connective tissue disease, systemic sclerosis, dermatomyositis and polymyositis (DM/PM), Sjögren syndrome, and rheumatoid arthritis (RA) was 22.1%, 14.3%, 14.3%, 3.0%, 21.3%, and 18.1%, respectively (no significant difference between AARD patients except DM/PM and HI). The prevalence of isolated anti-DFS70 antibody in HI and all AARD patients excluding RA was 14.8% (37/250) and 4.4% (9/204), respectively (P < .01 vs HI). Among anti-DFS70 antibody-positive cases, 63.4% (26/41) were DFS pattern by IIF and 23.5% (8/34) were HI and AARD patients excluding RA, respectively.The anti-DFS70 antibody prevalence in HI and AARD patients in Japan was similar. Furthermore, the anti-DFS70 antibody prevalence in HI and AARD in Japan is higher than in HI and AARD in regions other than Asia. This makes AARD differential diagnosis by antinuclear antibody screening difficult.2021年03月, Medicine, 100(9) (9), e24556, 英語, 国際誌研究論文(学術雑誌)

- Introduction: The coronavirus disease 2019 (COVID-19) pandemic is spreading rapidly all over the world. The Japanese government lifted the state of emergency, announced in April 2020, on May 25, but there are still sporadic clusters. Asymptomatic patients who can transmit severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cause some of these clusters. It is thus urgent to investigate the seroprevalence of antibodies against SARS-CoV-2 and their neutralizing activity. We conducted a cross-sectional study of >10,000 samples at hospitals in Hyogo Prefecture, Japan. Methods: Between August 6 and October 1, 2020, we collected samples of residual blood from the patients who visited or were admitted to five hospitals and a foundation in Hyogo. We tested the samples for antibodies against SARS-CoV-2 by electrochemiluminescence immunoassay (ECLIA) and chemiluminescent enzyme immunoassay (CLEIA). Sera that were positive by ECLIA or CLEIA were analyzed by an immunochromatographic (IC) test and neutralizing activity assay. Results: We tested 10,377 samples from patients aged between 0 and 99 years old; 27 cases (0.26%) were positive on the ECLIA, and 51 cases (0.49%) were positive on CLEIA. In the 14 cases that tested positive on both ECLIA and CLEIA, the positive rates on the IC test and for neutralizing activity were high (85% and 92%, respectively). In 50 cases (0.48%) that were positive by either ECLIA or CLEIA, the corresponding rates were low (20% and 6%, respectively). The positive rate of neutralizing antibody was 0.15%. Conclusions: These results indicate that most Hyogo Prefecture residents still do not have antibodies and should avoid the risk of incurring a SARS-CoV-2 infection. Two or more antibody tests should be required for seroepidemiological studies of the antibody for SARS-CoV-2, and a neutralizing activity assay is also essential.2021年01月, JMA journal, 4(1) (1), 41 - 49, 英語, 国内誌研究論文(学術雑誌)
- The gene mutation profiles of gastric neuroendocrine neoplasms are incompletely understood. The purpose of this study was to characterize the molecular pathology of poorly differentiated neuroendocrine carcinoma (NEC) and mixed neuroendocrine‒non-neuroendocrine neoplasm (MiNEN) of the stomach. Surgical cases of gastric NEC (n = 7) and MiNEN (n = 6) were examined by clinical review, immunohistochemistry, microsatellite instability (MSI) analysis and whole-exome sequencing. NEC cases consisted of small- (n = 2) and large-cell types (n = 4). All cases of MiNEN were histologically composed of large-cell type NEC and tubular adenocarcinoma. Whole-exome sequencing analysis detected recurrent mutations in TP53 in 8 cases (62%), and they were more frequently observed in MiNEN than in NEC (100% vs. 29%). Frameshift mutations of APC were observed in two cases of MiNEN. One case of large-cell type NEC had a frameshift mutation with loss of heterozygosity in RB1. The other mutated genes (e.g., ARID1 and KRAS) were detected in a single case each. A high level of MSI was confirmed in one case of MiNEN, which harbored mutations in two well-differentiated neuroendocrine tumor (NET)-related genes (MEN1 and ATRX1). In cases of MiNEN, two histological components shared mutations in TP53, APC and ZNF521, whereas alterations in CTNNB1, KMT2C, PTEN and SPEN were observed in neuroendocrine components only. In conclusion, TP53 is a single, frequently mutated gene in gastric NEC and MiNEN, and alterations in other genes are less common, resembling the mutation profiles of gastric adenocarcinomas. Gene mutations frequently observed in well-differentiated NET were uncommon but not entirely exclusive.2021年01月, Human pathology, 110, 1 - 10, 英語, 国際誌研究論文(学術雑誌)

- Birt-Hogg-Dubé (BHD) syndrome is an autosomal dominant disease characterized by benign skin hamartomas, pulmonary cysts leading to spontaneous pneumothorax, and an increased risk of renal cancer. BHD syndrome is caused by germline mutations in the folliculin (FLCN) gene, a putative tumor suppressor, which result in loss of function of the folliculin protein and may cause cancer predisposition. In a 45-year-old woman with anemia, lymphadenopathy, and a history of recurrent spontaneous pneumothorax, 18F-FDG PET/CT detected diffuse and slight 18F-FDG accumulation in the bone marrow, enlarged spleen, and systemic multiple enlarged lymph nodes. Genetic examination identified a germline nonsense mutation [c.998C > G (p.Ser333*)] on exon 9 of FLCN. Pathological examination of the lymph node revealed a diffuse neoplastic proliferation of plasmacytoid lymphocytes. The neoplastic lymphoid cells were positive for CD20, CD138, and light chain kappa as per immunohistochemistry and mRNA in situ hybridization, and a MYD88 gene mutation [c.755T > C (p.L252P)] was identified. Accordingly, she was diagnosed with lymphoplasmacytic lymphoma concomitant with BHD syndrome. To the best of our knowledge, this is the first report describing the development of hematological malignancy in a patient with BHD syndrome. The FLCN mutation might contribute lymphomagenesis as an additional mutation cooperating with the MYD88 mutation.2020年08月, International journal of hematology, 112(6) (6), 864 - 870, 英語, 国内誌[査読有り]研究論文(学術雑誌)
- The objective of the study was to compare the efficacy and safety of biological disease-modifying antirheumatic drugs (bDMARDs) between elderly-onset rheumatoid arthritis (EORA) and young-onset rheumatoid arthritis (YORA) patients. Patients with rheumatoid arthritis (RA) aged ≧18 years enrolled in a Japanese multicenter observational registry between 2009 and 2018 who had moderate or high disease activity when initiating bDMARDs were included. EORA was defined as RA with onset at 60 or over. After propensity score weighting for differences in confounding factors, generalized estimating equations were used to assess the relationship between the age of RA onset and bDMARD clinical effectiveness at 48 weeks after starting a bDMARD. Among a total of 7183 patients in the registry, 2815 (39.2%) were identified as EORA. The proportion of patients on bDMARDs was lower in the EORA as compared to the YORA (18.3% vs 28.0%, p < 0.001). Of the 989 bDMARD initiators, 364 (36.8%) were identified as EORA. The median follow-up duration was 48 weeks both in the EORA and in the YORA. After adjusting for differences in baseline characteristics between the two age groups, there was no significant difference in Clinical Disease Activity Index scores at 48 weeks (mean difference 1.01, 95% CI = - 0.62 to 2.64, p = 0.22). There was a non-significant trend toward lower remission in EORA (OR = 0.52, 95% CI = 0.24-1.14, p = 0.10), and low disease activity/remission was similar (OR = 0.86, 95% CI = 0.29-2.52, p = 0.77). Drug retention (HR = 0.95, 95% CI = 0.55-1.35, p = 0.78) and discontinuations due to adverse events (HR = 0.78, 95% CI = 0.38-1.18, p = 0.22) were similar between the two age groups after adjustment for confounders. In RA patients initiating bDMARDs, improvements in clinical disease at 48 weeks were similar between EORA and YORA. Drug retention and adverse events discontinuation were similar between the two age groups.2020年07月, Rheumatology international, 40(12) (12), 1987 - 1995, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- OBJECTIVES: Synovial fluids of rheumatoid arthritis (RA) patients commonly contain high concentrations of soluble CD14 (sCD14). To investigate its potential role in RA pathogenesis, we tested whether sCD14 binding transmits a signal to fibroblast-like synoviocytes from RA patients (RA-FLS). METHODS: The induction of pro-inflammatory cytokines, chemokines, and mediators by sCD14 stimulation of RA-FLS was quantified by real-time PCR and ELISA. Cell proliferation was assessed by the BrdU assay. LPS-RS, a Toll-like receptor 4 (TLR-4) antagonist, was used to block TLR-4 signaling. RESULTS: Soluble CD14 induced the expression of IL-6 mRNA and secretion of the protein. The expression of other pro-inflammatory cytokines and mediators, such as TNF-α, IL-8, intercellular adhesion molecule-1 (ICAM-1), MMP-3, and RANK ligand (RANKL), was also induced by sCD14. In addition, sCD14 stimulation promoted RA-FLS proliferation. LPS-RS abolished IL-6, IL-8, and ICAM-1 mRNA induction by sCD14 in RA-FLS. On the other hand, TNF-α and IL-17A increased TLR-4 expression by RA-FLS and amplified their sCD14-induced IL-6 expression. CONCLUSIONS: Soluble CD14 transmits inflammatory signals to RA-FLS via TLR-4. The effects of sCD14 may be augmented in inflammatory milieu. Our results suggest that sCD14 is involved in the pathogenesis of RA and may be a novel therapeutic target.2020年07月, Cells, 9(7) (7), 英語, 国際誌研究論文(学術雑誌)

- Acute myeloid leukemia (AML) with an inv(16)(p13q22) or t(16;16)(p13;q22) chromosomal abnormality represents one of the most common subtypes of de novo cases. These chromosomal rearrangements result in multiple CBFB-MYH11 fusion transcripts, with type-A being the most frequent. We here describe a unique case of de novo AML-M1, with inv(16)(p13q22), leading to an unusual CBFB-MYH11 fusion transcript, and der(7)t(7;11)(q31;q21). The fusion transcript involves a CBFB exon 5 with a breakpoint at nucleotide 754, an insertion of a 13-bp sequence of CBFB intron 5 at the fusion point, and the MYH11 exon 27 with a breakpoint at nucleotide 3464. To our knowledge, this CBFB-MYH11 fusion transcript has never been reported previously. The clinical characteristics of the present case are in line with previous reports suggesting that rare CBFB-MYH11 fusion transcripts lead to aberrant characteristics such as an atypical cytomorphology and additional cytogenetic abnormalities.2020年02月, Cancer genetics, 241, 72 - 76, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- BACKGROUND: Considering the physiological changes in serum procalcitonin (PCT) levels in newborns due to age, we recently established an age-specific percentile-based reference curve for serum PCT level. The present study aimed to determine the best cutoff percentile line using this reference curve for the differentiation between infected and colonized preterm infants. METHODS: A total of 52 preterm infants with positive bacterial culture (9 with bacterial infection, 43 with colonization) were enrolled within the study period. The 97.5th, 95.0th, 92.5th, 90.0th, 80.0th, 70.0th, 60.0th, and 50.0th percentile lines were drawn in the reference curve. PCT levels in infected or colonized infants were used, and sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. The best cutoff percentile line was determined in the receiver operating characteristic curve analysis. RESULTS: Of the 52 preterm infants, 9 were infected (5 and 4 infants with an onset of < 7 days and ≥ 7 days after birth, respectively), whereas 43 were colonized (6 and 37 infants with an onset of < 7 days and ≥ 7 days after birth, respectively). The best cutoff percentile lines were the 90.0th percentile (sensitivity, 0.800; specificity, 0.833; PPV, 0.800; NPV, 0.833) and 97.5th percentile (sensitivity, 1.00; specificity, 0.973; PPV, 0.800; NPV, 1.00) in infants with an onset of < 7 days and ≥ 7 days after birth, respectively. CONCLUSIONS: The age-specific percentile-based reference curve for serum PCT level is clinically applicable as a new tool for diagnosing infections in preterm infants with positive culture results, particularly at ≥ 7 days after birth.2020年01月, Clinical laboratory, 66(1) (1), 英語, 国際誌[査読有り]研究論文(学術雑誌)
- OBJECTIVES: Biologic treatment has recently revolutionized the management of RA. Despite this success, ∼30-40% of the patients undergoing biologic treatment respond insufficiently. The aim of this study was to identify several specific reliable metabolites for predicting the response of RA patients to TNF-α inhibitors (TNFi) and abatacept (ABT), using capillary electrophoresis-time-of-flight mass spectrometry (CE-TOFMS). METHODS: We collected serum from RA patients with moderate or high disease activity prior to biologic treatment, and obtained the serum metabolomic profiles of these samples using CE-TOFMS. The patients' response was determined 12 weeks after starting biologic treatment, according to the EULAR response criteria. We compared the metabolites between the response and non-response patient groups and analysed their discriminative ability. RESULTS: Among 43 total patients, 14 of 26 patients in the TNFi group and 6 of 17 patients in the ABT group responded to the biologic treatment. Of the metabolites separated by CE-TOFMS, 196 were identified as known substances. Using an orthogonal partial least-squares discriminant analysis, we identified five metabolites as potential predictors of TNFi responders and three as predictors of ABT responders. Receiver operating characteristic analyses for multiple biomarkers revealed an area under the curve (AUC) of 0.941, with a sensitivity of 85.7% and specificity of 100% for TNFi, and an AUC of 0.985, with a sensitivity of 100% and specificity of 90.9% for ABT. CONCLUSION: By metabolomic analysis, we identified serum biomarkers that have a high ability to predict the response of RA patients to TNFi or ABT treatment.2019年12月, Rheumatology (Oxford, England), 58(12) (12), 2153 - 2161, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- AIM: Subjective well-being (SWB) is a psychological construct that is synonymous with happiness. Many variables including age, sex, income, employment, and marital status are related to SWB. Health is also an important determinant of SWB that can be adversely affected in patients with chronic conditions such as rheumatoid arthritis (RA). In this study, we evaluate the SWB of RA patients and compare it with that of healthy controls. METHODS: We obtained the original dataset from the "Quality of Life Survey, 2013", which was conducted by the Economic and Social Research Institute, Cabinet Office, Government of Japan. In this survey, SWB was determined by asking participants to rate their happiness between 0 (very unhappy) and 10 (very happy). The survey also included a 56-point questionnaire regarding well-being-related variables. This questionnaire was administered to RA patients recruited from Kobe University Hospital, and clinical and treatment data were simultaneously collected. RESULTS: Multivariate analysis revealed that RA patients with high or moderate disease activity had SWB scores that were similar to those of controls. However, the SWB scores of RA patients in remission or with low disease activity were higher than those of controls (P = .013). SWB was associated with household income, self-assessment of living costs, self-assessment of health, depression/ anxiety, and social connection. CONCLUSIONS: For RA patients, achieving the therapeutic target can result in better SWB than that of healthy controls. Financial status, self-assessment of health, psychological stress, and social network are also important determinants for the SWB of RA patients.2019年10月, International journal of rheumatic diseases, 22(10) (10), 1863 - 1870, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- BACKGROUND: Rheumatoid arthritis-associated interstitial lung disease (RA-ILD) is a sometimes life-threatening complication in RA patients. SKG mice develop not only arthritis but also an ILD resembling RA-ILD. We previously reported that tofacitinib, a JAK inhibitor, facilitates the expansion of myeloid-derived suppressor cells (MDSCs) and ameliorates arthritis in SKG mice. The aim of this study was to elucidate the effect of tofacitinib on the ILD in SKG mice. METHODS: We assessed the effect of tofacitinib on the zymosan (Zym)-induced ILD in SKG mice histologically and examined the cells infiltrating the lung by flow cytometry. The effects of lung MDSCs on T cell proliferation and Th17 cell differentiation were assessed in vitro. We also evaluated the effects of tofacitinib on MDSCs and dendritic cells in vitro. RESULTS: Tofacitinib significantly suppressed the progression of ILD compared to the control SKG mice. The MDSCs were increased, while Th17 cells, group 1 innate lymphoid cells (ILC1s), and GM-CSF+ILCs were decreased in the lungs of tofacitinib-treated mice. MDSCs isolated from the inflamed lungs suppressed T cell proliferation and Th17 cell differentiation in vitro. Tofacitinib promoted MDSC expansion and suppressed bone marrow-derived dendritic cell (BMDC) differentiation in vitro. CONCLUSION: Tofacitinib facilitates the expansion of MDSCs in the lung and ameliorates ILD in SKG mice.2019年08月, Arthritis research & therapy, 21(1) (1), 184 - 184, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- Glutamine metabolism and the mechanistic target of rapamycin (mTOR) pathway are activated cooperatively in the differentiation and activation of inflammatory immune cells. But the combined inhibition of both pathways was rarely investigated. This study investigated how inhibiting both glutamine metabolism with 6-diazo-5-oxo-L-norleucine (DON) and mTOR with rapamycin affects immune cells and the arthritis in a mouse model. We revealed that rapamycin and DON additively suppressed CD4+ T cell proliferation, and both of them inhibited Th17 cell differentiation. While DON inhibited the differentiation of dendritic cells and macrophages and facilitated that of Ly6G+ granulocytic (G)-MDSCs more strongly than did rapamycin, G-MDSCs treated with rapamycin but not DON suppressed CD4+ T cell proliferation in vitro. The combination of rapamycin and DON significantly suppressed the arthritis in SKG mice more strongly than did each monotherapy in vivo. The numbers of CD4+ T and Th17 cells in the spleen were lowest in mice treated with the combination therapy. Thus, combined treatment with rapamycin and DON additively ameliorated the arthritis in SKG mice, possibly by suppressing CD4+ T cell proliferation and Th17 differentiation. These results suggest the combination of rapamycin and DON may be a potential novel therapy for arthritis.2019年04月, Scientific reports, 9(1) (1), 6374 - 6374, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- Receptor activator for nuclear factor κB ligand (RANKL)-independent osteoclastogenic pathway was reported recently. MicroRNA (miR)-124 has been known to suppress RANKL-dependent osteoclastogenesis by inhibiting NFATc1 expression. However, whether miR-124 regulates a RANKL-independent pathway has not been elucidated. In this study, we examined whether a RANKL-independent pathway is regulated by miR-124 in addition to the RANKL-dependent one. Using osteoclastogenic culture and pit-formation assay, we found that a miR-124 mimic inhibited osteoclastogenesis in mouse bone marrow-derived macrophages stimulated by TNF-α, IL-6, and M-CSF in the presence of osteoprotegerin. We also showed that the expression levels of osteoclast-specific genes and NFATc1 protein were suppressed in the miR-124 mimic-transfected cells by performing quantitative-polymerase chain reaction and western blotting. Our results indicate that miR-124 is important in inhibiting both RANKL-dependent and -independent osteoclast differentiation by suppressing NFATc1-mediated pathway.2019年04月, Rheumatol Int, 39(4) (4), 689 - 695, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- RATIONALE: Immunoglobulin G4 related disease (IgG4-RD) rarely coexists with other autoimmune diseases, though we had a patient whose primary clinical problem was shifted from IgG4-RD to systemic lupus erythematosus (SLE) after gastrectomy. The present paper aimed to report pathological findings and clinical course of the patient. PATIENT CONCERNS: The patient was a male aged 74 years old with gastric cancer characterized by the following symptoms: Raynaud phenomenon, polyarthralgia, and swollen parotid glands on both sides. Before gastrectomy, laboratory examination results showed renal dysfunction, hypocomplementemia, antinuclear antibodies (ANAs) positivity, and elevated serum IgG and IgG4 levels. DIAGNOSIS: Based on postoperative renal biopsy showing severe plasma cell infiltration with tubulointerstitial fibrosclerosis, the patient was diagnosed with IgG4-RD. Despite significant improvement in renal function and reduction in parotid gland swelling during the postoperative follow-up period, after 7 months of the gastrectomy, anti-DNA antibody levels were increased and serositis was detected, which indicated the onset of SLE. IgG4-type ANA were also detected in the sera of the patient. INTERVENTIONS: Treatment by oral prednisolone at 30 mg/day was initiated. OUTCOMES: Pericardial fluid, pleural effusions, and thickening of the gallbladder wall improved after 3 months of treatment according to computed tomography. LESSONS: This study presented a rare case of comorbidity, wherein the patient's primary problem progressed from IgG4-type ANA-positive IgG4-RD to SLE after excision of gastric cancer.2018年12月, Medicine, 97(51) (51), e13545, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- Recent studies have revealed a relationship between cellular metabolism and cell function in immune cells. Cellular metabolism not only provides supplemental ATP, but also supports dynamic changes in cell proliferation and differentiation. For example, T cells exhibit subset-specific metabolic profiles, and require certain types of metabolism for their functions. Determining the metabolic profiles that support inflammatory immune responses may lead to novel treatment strategies for chronic inflammatory diseases such as rheumatoid arthritis (RA). However, the mechanisms by which metabolism modulates cell function have been unclear. Recent studies have begun to unveil unexpected non-metabolic functions for metabolic enzymes in the context of inflammation, including roles in signaling and gene regulation. Here we describe recent findings related to immunometabolism, the metabolome of RA patients, and the metabolically independent functions of glycolytic enzymes. We discuss how metabolic processes impact immune cells, especially T cells and fibroblast like synoviocytes, which are considered the orchestrators of autoimmune arthritis.2018年09月, Immunological medicine, 41(3) (3), 89 - 97, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- Mycobacterium abscessus complex, including three subspecies-M. abscessus, M. massiliense, and M. bolletii-is resistant to a variety of antibiotics so limited treatment options are available. The susceptibility of these subspecies to antimicrobial agents depends in particular on the erm(41) sequevar and rrl mutations in the 23S rRNA, which are potentially related to clarithromycin (CLR) resistance. The purpose of this study was to carry out identification and molecular characterization of these subspecies based on variable number of tandem repeats (VNTR) analysis. Twenty-four M. abscessus complex strains were identified as M. abscessus and M. massiliense and these subspecies could be discriminated between based on their resistance to CLR, as determined by truncation or mutation of erm(41) or mutation of rrl, as illustrated by their VNTR patterns. In conclusion, we confirmed that the CLR susceptibility profiles could be differentiated according to the subspecies of M. abscessus complex strains by their VNTR patterns.2018年07月, Diagnostic microbiology and infectious disease, 91(3) (3), 256 - 259, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- BACKGROUND: The purpose of this study was to investigate associations between right ventricular (RV) function and left ventricular (LV) diastolic function in patients with reduced LV ejection fraction (LVEF) and preserved LVEF. METHODS: A total of 139 patients who had undergone echocardiography were recruited. LV diastolic function was determined as the ratio of mitral inflow E to mitral e' lateral annular velocities (E/e'). RV function was determined as the RV index of myocardial performance (RIMP). Patients were divided into two groups: the preserved LVEF group (n = 100, LVEF ≥ 50%) and the reduced LVEF group (n = 39, LVEF < 50%). RESULTS: Associations between RV function and LV diastolic function in patients with reduced LVEF and preserved LVEF differed significantly. RIMP correlated significantly with E/e' in patients with reduced LVEF (r = 0.47, p = 0.003), but not in those with preserved LVEF (r = 0.04, p = 0.68). An important finding of the multivariate regression analysis showed that RIMP was the only independent determinant of E/e' in patients with reduced LVEF, whereas age and gender (not RIMP) was the independent determinant of E/e' in patients with preserved LVEF. CONCLUSIONS: Associations between RV function and LV diastolic function in patients with reduced LVEF and preserved LVEF differed significantly, and RV function showed a close correlation with LV diastolic function in patients with reduced LVEF, but not in those with preserved LVEF. Thus, these findings may well have clinical implications for better management of patients with reduced LVEF.2018年06月, Journal of echocardiography, 16(2) (2), 81 - 86, 英語, 国内誌[査読有り]研究論文(学術雑誌)
- RATIONALE: TAFRO syndrome is a systemic inflammatory disorder characterized by thrombocytopenia, anasarca, fever, reticulin fibrosis, renal dysfunction, and organomegaly. In contrast to that in multicentric Castleman disease, interleukin-6 targeting strategies seem ineffective in some TAFRO syndrome cases; however, the optimal treatment remains unclear. Here, we report 2 cases of TAFRO syndrome, where 1 with cardiomyopathy, successfully treated with tacrolimus. This is the first case report of successful treatment with tacrolimus in TAFRO syndrome. PATIENT CONCERNS: Both patients (cases 1 and 2) developed fever, anasarca, thrombocytopenia, renal dysfunction, and mild hepatosplenomegaly. DIAGNOSES: In both patients, lymph node pathology revealed mixed type Castleman disease-like features, and bone marrow showed reticulin myelofibrosis. TAFRO syndrome was diagnosed based on the patients' laboratory, clinical, and pathologic findings. In case 2, we observed a rare complication of cardiomyopathy with no evidence of takotsubo cardiomyopathy or viral myocarditis. INTERVENTIONS AND OUTCOMES: In case 1, tocilizumab combined with glucocorticoids was ineffective and caused septic shock; additionally, cyclosporine A was discontinued because of hepatotoxicity. However, tacrolimus was effective in resolving TAFRO syndrome without any adverse events. In case 2, tacrolimus completely reversed TAFRO syndrome and was also effective in cardiomyopathy. LESSONS: This report suggests that tacrolimus is potentially effective and safe as an initial treatment and a glucocorticoid-sparing agent. Our literature review shows that calcineurin inhibitors, including tacrolimus, may be effective in TAFRO syndrome. Since previous studies indicate a role of Th1 inflammation in TAFRO syndrome pathogenesis, tacrolimus may, therefore, be effective in treating TAFRO syndrome.2018年06月, Medicine, 97(23) (23), e11045, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- Background Our aim was to determine whether the postnatal age or postmenstrual age is a more appropriate criterion for evaluating foetal haemoglobin concentrations. Methods Blood samples ( n = 1095) were obtained from 394 infants and were divided into two groups based on gestational age at birth: <37 weeks ( n = 491) and ≥37 weeks ( n = 604). (1) Foetal haemoglobin concentrations divided by one month at age after birth were compared between the groups. (2) Foetal haemoglobin concentrations divided into ≤9 months from last menstruation and one month thereafter were compared between the groups. Results In samples from infants ≥37 weeks' gestational age at birth, the median foetal haemoglobin concentrations were 69.5%, 21.4% and 3.6% at 0-1 month, 2-3 months and ≥5 months after birth, respectively. The median foetal haemoglobin concentrations in infants <37 weeks' gestational age at birth were 75.5%, 62.7% and 5.1% at 0-1 month, 2-3 months and ≥5 months after birth, respectively. The median foetal haemoglobin concentrations in infants <37 weeks' gestational age at birth were significantly higher than that in infants ≥37 weeks' gestational age at birth at all postnatal age points. (2) There was no significant difference between the groups at all age points after nine months of postmenstrual age: 72.5 and 75.3% at 9-10 months, 25.1 and 26.6% at 11-12 months and 5.5 and 4.6% at >13 months after last menstruation in infants ≥37 and <37 weeks' gestational age at birth, respectively. Conclusions Evaluation of foetal haemoglobin concentrations at postmenstrual age is unaffected by gestational age at birth.2018年05月, Annals of clinical biochemistry, 55(3) (3), 400 - 403, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- ETV6-ABL1 fusion is a rare but recurrent oncogenic lesion found in childhood B-cell precursor acute lymphoblastic leukemia (BCP-ALL), without an established chromosomal abnormality, and is associated with poor outcome. In ETV6-ABL1-positive cases, an in-frame fusion produced by a complex rearrangement results in constitutive chimeric tyrosine kinase activity. Monosomy 7 is also a rare and unfavorable chromosomal abnormality in childhood BCP-ALL. Here, we report a 14-year-old female BCP-ALL patient with ETV6-ABL1 fusion combined with monosomy 7. She was admitted to our hospital because of persistent fever. Bone marrow nuclear cell count on admission was 855,000/µL with 90.0% blastic cells of lymphoid morphology. Blasts were positive for CD10, CD19, CD20, CD34, cyCD79a, cyTdT, HLA-DR, and CD66c, had a karyotype of 45, XX, - 7 [18/20] and a split signal for ABL1 FISH probe (92.7%), and were sensitive to tyrosine kinase inhibitors, imatinib and dasatinib, in vitro. ETV6-ABL1 fusion transcript was identified by whole transcriptome sequencing and confirmed by RT-PCR. She was treated with the high-risk protocol based on ALL-BFM 95, achieved complete remission (CR) after induction chemotherapy, and maintained CR for 4 months. To our knowledge, this is the first report of ETV6-ABL1 fusion combined with monosomy 7 in childhood BCP-ALL.2018年05月, International journal of hematology, 107(5) (5), 604 - 609, 英語, 国内誌[査読有り]研究論文(学術雑誌)

- A 38-year-old woman was diagnosed with systemic lupus erythematosus and received immunosuppressive therapy. After 6 months of treatment, workup for low-grade fever yielded elevated enzyme-linked immunosorbent assay titers for Aspergillus antigen in serum and ascites, leading to the diagnosis of disseminated aspergillosis. Transthoracic echocardiography revealed a claviform vegetation attached to the left ventricular anterior septum. Two days after the start of antifungal Amphotericin-B therapy, the patient suffered from several neurologic disorders. A second transthoracic echocardiography revealed that the vegetation decreased in size. Two weeks later, the vegetation increased again. Combination therapy of Amphotericin-B and Voriconazole was initiated, and the vegetation eventually disappeared completely. © 2017 Wiley Periodicals, Inc.

- BACKGROUND: Duchenne muscular dystrophy (DMD), the most common inherited muscular disease in childhood, is caused by dystrophin deficiency because of mutations in the DMD gene. Although DMD is characterized by fatal progressive muscle wasting, cardiomyopathy is the most important nonmuscle symptom threatening the life of patients with DMD. The relationship between cardiac involvement and dystrophin isoforms has not been analyzed. METHODS AND RESULTS: The results of 1109 echocardiograms obtained from 181 Japanese DMD patients with confirmed mutations in the DMD gene were retrospectively analyzed. Patients showed an age-related decline in left ventricular ejection fraction. Patients were divided by patterns of dystrophin isoform deficiency into 5 groups. The cardiac dysfunction-free survival was significantly higher in the group with mutations in the Dp116 coding region than the others, whereas no significant differences in the other 3 groups. At age 25 years, the cardiac dysfunction-free rate was 0.6 in the Dp116 group, but only 0.1 in others. PCR amplification of Dp116 transcript in human cardiac muscle indicated promoter activation. CONCLUSIONS: Left ventricular ejection fraction in DMD declined stepwise with age. Cardiac dysfunction was less frequent in Dp116-deficient than other patients with DMD. Dp116 transcript was identified in human cardiac muscle for the first time. These results indicate that Dp116 is associated with cardiac involvement in DMD.2018年01月, Circulation.

- Osteoclasts play a critical role not only in bone homeostasis but also in inflammatory osteolysis, such as that occurring in inflammatory arthritis and systemic inflammation. In both inflammation conditions, inflammatory cytokines like Interleukin (IL)-1, IL-6 and tumor necrosis factor (TNF)-α induce RANKL expression in osteoblasts, but the roles of these cytokines in osteoclast activation remain unclear. S100A12, an S100 family member, is a low-molecular-weight calcium-binding protein. Although it has a pro-inflammatory role, its effects on osteoclast differentiation have been unclear. Here we examined the direct effects of S100A12 on human osteoclasts in vitro. S100A12 facilitated osteoclast formation in the presence of RANKL, as judged by the cells' morphology and elevated expression of osteoclast-related molecules, including NFATc1, ACP5, CALCR, and ITGβ3. In addition, S100A12 administration markedly enhanced the osteoclasts' bone resorption ability, consistent with their increased expression levels of CTSK and CA2. Blocking RAGE and TLR4 cancelled the effects of S100A12. Our results indicate that S100A12 is a potential therapeutic target for inflammatory osteolysis.2018年, PloS one, 13(9) (9), e0204140, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- Background: Myeloid-derived suppressor cells (MDSCs) are a highly heterogeneous population of immature myeloid cells with immunosuppressive function. Although their function in tumor-bearing conditions is well studied, less is known about the role of MDSCs in various organs under non-neoplastic inflammatory conditions. Main body: MDSCs are divided into two subpopulations, G-MDSCs and M-MDSCs, and their distribution varies between organs. MDSCs negatively control inflammation in inflamed organs such as the lungs, joints, liver, kidneys, intestines, central nervous system (CNS), and eyes by suppressing T cells and myeloid cells. MDSCs also regulate fibrosis in the lungs, liver, and kidneys and help repair CNS injuries. MDSCs in organs are plastic and can differentiate into osteoclasts and tolerogenic dendritic cells according to the microenvironment under non-neoplastic inflammatory conditions. Conclusion: This article summarizes recent findings about MDSCs under inflammatory conditions, especially with respect to their function and differentiation in specific organs.2018年, Inflammation and regeneration, 38(19) (19), 19 - 19, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- OBJECTIVE: SKG mice develop interstitial lung disease (ILD) resembling rheumatoid arthritis-associated ILD in humans. The aim of this study was to clarify the mechanism underlying the lung pathology by analyzing lung-infiltrating cells in SKG mice with ILD. METHODS: We assessed the severity of zymosan A (ZyA)-induced ILD in SKG mice histologically, and we examined lung-infiltrating cells by flow cytometry. Total lung cells and isolated monocytic myeloid-derived suppressor cells (MDSCs) were cultured in vitro with granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4. The proliferation of 5,6-carboxyfluorescein diacetate N-succinimidyl ester-labeled naive T cells cocultured with isolated CD11b+Gr-1dim cells and MDSCs was evaluated by flow cytometry. CD11b+Gr-1dim cells were adoptively transferred to ZyA-treated SKG mice. RESULTS: MDSCs, Th17 cells, and group 1 and 3 innate lymphoid cells (ILC1s and ILC3s) were increased in the lungs; the proportion of these cells varied with ILD severity. In this process, we found that a unique cell population, CD11b+Gr-1dim cells, was expanded in the severely inflamed lungs. Approximately half of the CD11b+Gr-1dim cells expressed CD11c. CD11b+Gr-1dim cells were induced from monocytic MDSCs with GM-CSF in vitro and were considered tolerogenic because they suppressed T cell proliferation. These CD11b+Gr-1dim cells have never been described previously, and we termed them CD11b+Gr-1dim tolerogenic dendritic cell (DC)-like cells. Th17 cells, ILC1s, and ILC3s in the inflamed lung produced GM-CSF, which may have expanded CD11b+Gr-1dim tolerogenic DC-like cells in vivo. Furthermore, adoptive transfer of CD11b+Gr-1dim tolerogenic DC-like cells significantly suppressed progression of ILD in SKG mice. CONCLUSION: We identified unique suppressive myeloid cells that were differentiated from monocytic MDSCs in SKG mice with ILD, and we termed them CD11b+Gr-1dim tolerogenic DC-like cells.2017年12月, Arthritis & rheumatology (Hoboken, N.J.), 69(12) (12), 2314 - 2327, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- In response to the accident at Tokyo Electric Power Company's Fukushima Dai-ichi Nuclear Power Plant (FDNPP), vehicle-borne monitoring was used to map radiation levels for radiological protection of the public. By convention measurements from vehicle-borne surveys are converted to the ambient dose equivalent rate at 1 m height in the absence of the vehicle. This allows for comparison with results from other types of survey, including surveys with hand-held or airborne instruments. To improve the accuracy of the converted results from vehicle-borne surveys, we investigated combining measurements from two detectors mounted on the vehicle at different heights above the ground. A dual-detector setup was added to a JAEA monitoring car and compared against hand-held survey meter measurements in Fukushima Prefecture. The results obtained by combining measurements from two detectors were within ±20% of the hand-held reference measurements. The mean absolute percentage deviation from the reference measurements was 7.2%. The combined results from the two detectors were more accurate than those from either the roof-mounted detector, or the detector inside the vehicle, taken alone. One issue with vehicle-borne surveys is that ambient dose equivalent rates above roads are not necessarily representative of adjacent areas. This is because radiocesium is often deficient on asphalt surfaces, as it is easily scrubbed off by rain, wind and vehicle tires. To tackle this issue, we investigated mounting heights for vehicle-borne detectors using Monte Carlo gamma-ray simulations. When radiocesium is deficient on a road compared to the adjacent land, mounting detectors high on vehicles yields results closer to the values adjacent to the road. The ratio of ambient dose equivalent rates reported by detectors mounted at different heights in a dual-detector setup indicates whether radiocesium is deficient on the road compared to the adjacent land.2017年10月, Journal of environmental radioactivity, 177, 1 - 12, 英語, 国際誌[査読有り]
- A 78-year-old female with massive pericardial effusion fulfilled diagnostic criteria for immunoglobulin G4 (IgG4)-related disease. Although her adenosine deaminase (ADA) level in the pericardial effusion was high, all the tests for tuberculosis infection were negative. Immunostaining of the pericardium biopsy specimen revealed remarkably increased IgG4-positive cells. This is the first report describing IgG4-related pericarditis with elevated ADA level. We also demonstrate the elevated interleukin-10 (IL-10) level in pericardial fluid and IL-10-producing T-cells in the pericardium.2017年09月, Modern rheumatology, 27(5) (5), 894 - 897, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- Purpose To evaluate the incidence of fragility fractures associated with high-dose glucocorticoid therapy in patients with systemic rheumatic disease. METHODS: A retrospective study of patients who were treated with high-dose prednisolone (> 0.8 mg/kg) for systemic rheumatic disease at Kobe University Hospital from April 1988 to March 2012. The primary outcome was a major osteoporotic fracture (defined as a clinical vertebral, hip, forearm, or proximal humerus fracture) after high-dose glucocorticoid therapy. For postmenopausal women and men over 40 of age, the patient's fracture risk at the beginning of high-dose glucocorticoid therapy was assessed by the World Health Organization's Fracture Risk Assessment Tool (FRAX®). Results Of 229 patients (median age: 49 years), 57 suffered a fragility fracture during the observation period (median observation period: 1558 days). Of 84 premenopausal patients, 5 suffered a fracture. In contrast, of 86 postmenopausal female, 36 suffered a fracture. Fragility fractures were far more frequent than predicted by the FRAX® score. Patients with FRAX® scores over 8.3% had a particularly high risk of fracture. Conclusions Fragility fractures associated with high-dose glucocorticoid therapy are common among postmenopausal women. Extreme care should be taken especially for postmenopausal women when high-dose glucocorticoid therapy is required.2017年06月, Bone reports, 6, 3 - 8, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- [Performance Utility of High Sensitivity Quantitative Assay for HBs Antigen].A high sensitivity quantitative assay for hepatitis B virus (HBV) surface antigen (HBsAg-HQ assay) was recently developed and is useful for earlier detection of HBV reactivation. We created HBsAg-HQ assay operational proce- dures by the sample transport system and laboratory information system. In this study, we evaluated the perfor- mance and utility of the HBsAg-HQ assay based on our operational procedures using internal quality control (IQC) data and 13,762 samples routinely measured for 8 months. The IQC data of the HBsAg-HQ assay demonstrated good accuracy (CV: 1.6-2.7%). The difference in IQC data between two of the same analyzers or several reagent lots had no clinical significance. Of 13,762 samples, HBsAg titer was negative in 12,592(91.5%) and positive in 1,169(8.5%), and HBsAg negative samples were remarkably lower(<0.001 IU/mL) than the cut-off value(0.005 IU/mL). Among 114 HBsAg weakly positive samples ranging from 0.005 to 1.000 IU/mL, false positive results occurred in 12 samples, which were converted into negative results after re-measurement. We could effectively perform carry-over prevention and dilution of high titer samples using our operational procedures. Furthermore, we performed inhibition test in 52 HBsAg weakly positive samples, and 20 samples, most of which were taken from patients with connective tissue disease or malignancy, were judged as non-specific reactivity. Taken together, our operational HBsAg-HQ assay procedures may contribute to efficient workflow for routine testing. Moreover, the HBsAg-HQ assay may be clinically useful for not only highly sensitive assays, but also for reducing false positives.2017年03月, Rinsho byori.

- Recent studies have shown that cellular metabolism plays an important role in regulating immune cell functions. In immune cell differentiation, both interleukin-17-producing T (Th17) cells and dendritic cells (DCs) exhibit increased glycolysis through the upregulation of glycolytic enzymes, such as hexokinase-2 (HK2). Blocking glycolysis with 2-deoxyglucose was recently shown to inhibit Th17 cell differentiation while promoting regulatory T (Treg) cell generation. However, 2-DG inhibits all isoforms of HK. Thus, it is unclear which isoform has a critical role in Th17 cell differentiation and in rheumatoid arthritis (RA) pathogenesis. Here we demonstrated that 3-bromopyruvate (BrPA), a specific HK2 inhibitor, significantly decreased the arthritis scores and the histological scores in SKG mice, with a significant increase in Treg cells, decrease in Th17 cells, and decrease in activated DCs in the spleen. In vitro, BrPA facilitated the differentiation of Treg cells, suppressed Th17 cells, and inhibited the activation of DCs. These results suggested that BrPA may be a therapeutic target of murine arthritis. Although the role of IL-17 is not clarified in the treatment of RA, targeting cell metabolism to alter the immune cell functions might lead to a new therapeutic strategy for RA.2017年02月, Scientific reports, 7, 42412 - 42412, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- [Evaluation of a Fully Automated Analyzer for Antinuclear Antibody Test Using Indirect Immunofluorescence Assay].The fully automated HELIOS® system for antinuclear antibody (ANA) test is capable of automatically per- forming all IFA procedures. We evaluated the analytical performance, characteristics and utility of HELIOS system as ANA screening test. We compared HELIOS system and the conventional methods in sera from 161 connective tissue disease (CTD) patients and 250 healthy individuals. The presence and titer of ANA were automatically determined by performing HELIOS system at 1:80 dilution and the ANA titers were com- pensated by several dilution and visual determination in sera with a high ANA titer and ANA-positive sera combined with anti-cytoplasmic antibody. The ANA staining patterns were assessed by visual determination of the digital image on HELIOS system. The total concordance rate between the conventional method and HELIOS system was 94.4%. The concordance of ANA titer (within ± 1 tube difference) between the con- ventional method and automated or compensated evaluation of HELIOS system was 85.7% or 98.8%, respec- tively. The concordance rate of six nuclear staining patterns was from 81.4% to 100% and the discrepancies of granular staining pattern might be caused by the fixation of HEp-2 cells. The positive rates of ANA in CTD patients and healthy individuals were comparable with the conventional methods. Taken together, HELIOS system can appropriately perform the automated determination of ANA except in some cases and is useful as ANA screening test. Furthermore, this system can contribute not only an efficient IFA procedure but also the ANA standardization by IFA. [Original].2017年02月, Rinsho byori.

- [The Deveroppment of Screening Methods Using the Disk Diffusion Method for Carbapenemase-producing Enterobacteriaceae].Carbapenem-resistant Enterobacteriaceae (CRE) are increasing globally. Particularly, carbapenemase-producing Enterobacteriaceae (CPE) are of concern. Rapid and accurate detection of these strains is critical for appropriate antimicrobial use and hospital infection control. In the present study, criteria for CPE screening were examined using a carbapenem susceptibility disk. Carbapenemase producers showed minimal inhibition zones for faropenem (5 μg): 6-12 mm (mean: 6.9 mm). Some strains with the IMP-6 genotype showed inhibition zones of >30 mm for imipenem (10 μg) and biapenem (10 μg). All strains that formed inhibition zones for FRPM had the IMP-6 genotype. The cut off values of carbapenemase-producers, determined by ROC analysis, were 12 mm for FRPM, 24 mm for meropenem (10 μg), 29 mm for BIPM, 25 mm for doripenem (10 μg), 26 mm for IPM, and 24 mm for panipenem (10 μg). Thus, the sensitivity was the highest (100%) for FRPM. Specificities were 93.44% for MEPM and DRPM and 85.25% for FRPM. Consequently, a drug sensitivity test using FRPM (5 μg) disks facilitates simple and accurate CPE screening.2017年01月, Kansenshogaku zasshi.

- Very early stage left ventricular endocardial dysfunction of patients with hypereosinophilic syndrome.Cardiac involvement in hypereosinophilic syndrome (HES) patients entails significant morbidity and mortality. Left ventricular (LV) endocardial damage is important for the development of cardiac involvement in HES patients. However very early stage LV endocardial damage, such as prior to the first stage of an acute necrotic stage, remains uncertain. We studied 32 HES patients, all with normal conventional echocardiographic findings. Global radial and circumferential strain (GRS and GCS) were determined for each peak global strain curve from the mid-LV short-axis view, and global longitudinal strain (GLS) was averaged each peak global strain curve from standard apical views by means of two-dimensional speckle-tracking method. Thirty-one age-, gender-, LV ejection fraction-matched normal subjects were studied for comparison. GRS and GRS were similar for HES patients and normal controls, but GLS for HES patients was significantly lower than that for normal controls (16.2 ± 3.3 % vs 19.3 ± 2.9 %, p < 0.001). Furthermore, receiver operating characteristic curve analysis identified GLS ≤17.0 % as the best predictor of LV endocardial dysfunction with a sensitivity of 66 %, specificity of 78 %, and area under the curve of 0.781 (p = 0.0001). In conclusions, LV endocardial dysfunction pre-existed even in HES patients without apparent cardiac involvement. GLS as assessed with the two-dimensional speckle-tracking method is a promising tool for the better management of very early stage of HES patients.2016年09月, The international journal of cardiovascular imaging, 32(9) (9), 1357 - 1361, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- BACKGROUND: Endothelin-1 (ET-1) is important in the pathogenesis of systemic sclerosis (SSc). ET-1 binds two receptors, endothelin type A (ETA) and endothelin type B (ETB). Dual ETA/ETB receptor antagonists and a selective ETA receptor antagonist are used clinically to treat SSc, and the effect of these antagonists on fibroblast activation has been described. However, the role of ETB receptor signaling in fibrogenesis is less clear. This study was conducted to evaluate the profibrotic function of ETB receptor signaling in a murine model of bleomycin (BLM)-induced scleroderma. METHODS: We used ETB receptor-knockout (ETBKO) mice, which are genetically rescued from lethal intestinal aganglionosis by an ETB receptor transgene driven by the human dopamine β-hydroxylase (DβH)-gene promoter, and wild-type mice with DβH-ETB (WT). BLM or phosphate-buffered saline (PBS) was administered subcutaneously by osmotic minipump, and skin fibrosis was assessed by dermal thickness, subcutaneous fat atrophy, and myofibroblast count in the dermis. Dermal fibroblasts isolated from ETBKO and WT mice were cultured in vitro, stimulated with BLM or ET-1, and the expression of profibrotic genes was compared by quantitative PCR. RESULTS: Dermal thickness, subcutaneous fat atrophy, and myofibroblast counts in the dermis were significantly reduced in ETBKO mice compared to WT mice, after BLM treatment. Compared with wild-type, dermal fibroblasts isolated from ETBKO mice showed lower gene expressions of α-smooth muscle actin and collagen 1α1 in response to BLM or ET-1 stimulation in vitro. CONCLUSIONS: ET-1-ETB receptor signaling is involved in skin sclerosis and in collagen synthesis by dermal fibroblasts.2016年05月, Arthritis research & therapy, 18(1) (1), 113 - 113, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- BACKGROUND: Most patients with spinal muscular atrophy lack the survival motor neuron 1 gene (SMN1) in the telomeric region of the spinal muscular atrophy locus on chromosome 5q13. On the other hand, the copy number of SMN2, a centromeric homolog of SMN1, is increased in many of these patients. This study aimed to clarify the mechanism underlying these structural variations. METHODS: We determined the copy numbers of telomeric and centromeric genes in the spinal muscular atrophy locus of 86 patients and 22 control subjects using multiplex ligation-dependent probe amplification analysis. Then, we chose 74 patients lacking SMN1 exons 7 and 8, and compared their dataset with that of 22 control subjects retaining SMN1 exons 7 and 8. RESULTS: The SMN2 copy number was shown to vary widely and to correlate with the disease severity of the patients. Interestingly, telomeric NAIP and telomeric GTF2H2 showed similar tendencies. We also noted positive correlations among the copy number of SMN2 and the telomeric genes of the spinal muscular atrophy locus. However, the copy numbers of centromeric NAIP and centromeric GTF2H2 were stable among the patients, with both approximating a value of two. CONCLUSION: Our findings suggested that the telomeric region of the spinal muscular atrophy locus appears to be susceptible to structural variation, whereas the centromeric region is stable. Moreover, according to our results, new SMN2 copies may be generated in the telomeric region of the spinal muscular atrophy locus, supporting the SMN1-to-SMN2 gene conversion theory.2016年05月, Pediatric neurology, 58, 83 - 9, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- Procalcitonin (PCT) levels are elevated early after birth in newborn infants; however, the physiological features and reference of serum PCT concentrations have not been fully studied in preterm infants. The aims of the current study were to establish an age-specific percentile-based reference curve of serum PCT concentrations in preterm infants and determine the features. The PCT concentration peaked in infants at 1 day old and decreased thereafter. At 1 day old, serum PCT concentrations in preterm infants <34 weeks' gestational age were higher than those in late preterm infants between 34 and 36 weeks' gestational age or term infants ≥37 weeks' gestational age. Although the 50-percentile value in late preterm and term infants reached the adult normal level (0.1 ng/mL) at 5 days old, it did not in preterm infants. It took 9 weeks for preterm infants to reach it. Serum PCT concentrations at onset in late-onset infected preterm infants were over the 95-percentile value. We showed that the physiological feature in preterm infants was significantly different from that in late preterm infants, even in those <37 weeks' gestational age. To detect late-onset bacterial infection and sepsis, an age-specific percentile-based reference curve may be useful in preterm infants.2016年04月, Scientific reports, 6, 23871 - 23871, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- OBJECTIVE: MicroRNAs (miRNAs) are small endogenous, non-coding RNAs that act as post-transcriptional regulators. We analysed the in vivo effect of miRNA-124 (miR-124, the rat analogue of human miR-124a) on adjuvant-induced arthritis (AIA) in rats. METHODS: AIA was induced in Lewis rats by injecting incomplete Freund's adjuvant with heat-killed Mycobacterium tuberculosis. Precursor (pre)-miR-124 was injected into the right hind ankle on day 9. Morphological changes in the ankle joint were assessed by micro-CT and histopathology. Cytokine expression was examined by western blotting and real-time RT-PCR. The effect of miR-124 on predicted target messenger RNAs (mRNAs) was examined by luciferase reporter assays. The effect of pre-miR-124 or pre-miR-124a on the differentiation of human osteoclasts was examined by tartrate-resistant acid phosphatase staining. RESULTS: We found that miR-124 suppressed AIA in rats, as demonstrated by decreased synoviocyte proliferation, leucocyte infiltration and cartilage or bone destruction. Osteoclast counts and expression level of receptor activator of the nuclear factor κB ligand (RANKL), integrin β1 (ITGB1) and nuclear factor of activated T cells cytoplasmic 1 (NFATc1) were reduced in AIA rats treated with pre-miR-124. Luciferase analysis showed that miR-124 directly targeted the 3'UTR of the rat NFATc1, ITGB1, specificity protein 1 and CCAAT/enhancer-binding protein α mRNAs. Pre-miR-124 also suppressed NFATc1 expression in RAW264.7 cells. Both miR-124 and miR-124a directly targeted the 3'-UTR of human NFATc1 mRNA, and both pre-miR-124 and pre-miR-124a suppressed the differentiation of human osteoclasts. CONCLUSIONS: We found that miR-124 ameliorated AIA by suppressing critical prerequisites for arthritis development, such as RANKL and NFATc1. Thus, miR-124a is a candidate for therapeutic use for human rheumatoid arthritis.2016年03月, Annals of the rheumatic diseases, 75(3) (3), 601 - 8, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- [Evaluation of a Computer-Aided Microscope System and Its Anti-Nuclear Antibody Test Kit for Indirect Immunofluorescence Assay].Antinuclear antibody (ANA) testing is indispensable for diagnosing and understanding clinical conditions of autoimmune diseases. The indirect immunofluorescence assay (IFA) is the gold standard for ANA screening, and it can detect more than 100 different antibodies, such as anti-PCNA as well as anti-cytoplasmic antibodies. However, complicated procedures of conventional IFA and visual interpretation require highly skilled laboratory staff. This study evaluates the capability, characteristics, and applicability of the recently developed ANA detection system (EUROPattern Cosmic IFA System, EPA) using HEp20-10 cells and the automated pattern recognition microscope. Findings using EPA and conventional methods were compared in 282 sera obtained from connective tissue disease patients and 250 sera from healthy individuals. The concordance of the positivity rate, antibody titer (within +/- 1 tube difference), and the accurate recognition rate of ANA patterns between the automated EPA method and the microscopic judgement of the EPA image by eye was 98.9, 97.4, and 55.3%, respectively. The EPA method showed concordance of the positivity rate as high as 93.3% and concordance of the antibody titer as high as 94.0% (within +/- 1 titer) compared with the conventional method. Regarding the four typical patterns of ANA (homogeneous, speckled, nucleolar, and centromere), large differences between the EPA and conventional methods were not observed, and the rate of concordance between the final EPA result and the conventional method was from 94.1 to 100%. The positivity rate of ANA using the EPA and conventional methods showed marked agreement among the six connective tissue diseases (SLE, MCTD, SSc, PM/DM, and SS) and healthy individuals. Although the EPA system is not considered a complete system and laboratory staff should verify the results, it is a useful system for routine ANA analysis because it contributes to ANA standardization and an efficient workflow.2016年02月, Rinsho byori.

- In rheumatoid arthritis (RA), synovial fibroblasts (RA-SFs) accumulate in affected joints, where they play roles in inflammation and joint destruction. RA-SFs exhibit tumor-like proliferation and are resistant to apoptosis. Although RA-SF activation is well described, negative regulators of RA-SF activation are unknown. We previously reported that histone deacetylase (HDAC) inhibitors facilitate apoptosis in RA-SFs. Here we found that RA-SFs treated with the HDAC inhibitor Trichostatin A (TSA) exhibited an upregulation of the immediate early response gene X-1 (IEX-1). IEX-1 has roles in apoptosis sensitivity, cell-cycle progression, and proliferation, and is reported to be involved in immune responses, inflammation, and tumorigenesis, and to have anti-arthritic properties. To investigate IEX-1's role in RA-SFs, we used in vitro-cultured synovial fibroblasts from RA and osteoarthritis (OA) patients. We confirmed that TSA upregulated the IEX-1 protein and mRNA expressions in RA-SFs by western blotting and quantitative RT-PCR. Inhibiting HDAC1, 2, and 3 (but not 6 or 8) also upregulated IEX-1. The IEX-1 mRNA levels were higher in RA-SFs than in OA-SFs, and were further upregulated in RA-SFs by the pro-inflammatory cytokines TNFα and IL-1β. The staining of surgical specimens showed that IEX-1 was present in the pannus from affected RA joints. Si-RNA-mediated IEX-1 knockdown upregulated the lipopolysaccharide (LPS)-induced expression of TNFα and various chemokine mRNAs, indicating that IEX-1 downregulates TNFα and chemokines. Furthermore, apoptosis analysis showed that IEX-1 knockdown protected RA-SFs from apoptosis induced by TSA or by an anti-Fas mAb, indicating that IEX-1 is pro-apoptotic in RA-SFs. Collectively, our results showed that IEX-1 is induced by TNFα and IL-1β in RA-SFs, in which it suppresses TNFα and chemokine production and induces apoptosis; thus, IEX-1 negatively regulates RA-SF activation. Further investigation of IEX1's functions in RA-SFs may lead to new therapeutic approaches for RA.2016年, PloS one, 11(10) (10), e0164350, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- A 72-year-old man was diagnosed with rheumatoid arthritis (RA) and prior hepatitis B virus (HBV) infection. He began treatment with salazosulfapyridine (SASP). Several months later, his blood tests reflected a slightly elevated liver function. Serum tests were positive for hepatitis B surface antigen and HBV-DNA, and the diagnosis of de novo HBV hepatitis was made. A genetic analysis showed that he had polymorphisms of ABCG2 and NAT2, which could lead to high plasma concentrations of SASP and sulfapyridine. To the best of our knowledge, this is the first report of de novo hepatitis developing during SASP monotherapy for RA.2016年, Internal medicine (Tokyo, Japan), 55(10) (10), 1371 - 3, 英語, 国内誌[査読有り]研究論文(学術雑誌)

- OBJECTIVE: Myeloid-derived suppressor cells (MDSCs) are a heterogeneous population of cells that have the ability to suppress T cell responses. The aim of this study was to evaluate the effects of the JAK inhibitor tofacitinib on MDSCs in a mouse model of rheumatoid arthritis. METHODS: Arthritis was induced in SKG mice by zymosan A (ZyA) injection. MDSCs isolated from the bone marrow (BM) of donor SKG mice with arthritis were adoptively transferred to recipient mice with arthritis. In a separate experiment, tofacitinib was administered to arthritic SKG mice subcutaneously via osmotic pump, in some cases followed by injection of an anti-Gr-1 monoclonal antibody (mAb). BM cells from untreated mice were cultured for 5 days with granulocyte-macrophage colony-stimulating factor, with or without tofacitinib, and then analyzed by flow cytometry. RESULTS: The numbers of MDSCs and polymorphonuclear MDSCs (PMN-MDSCs) were significantly increased in the spleens of SKG mice following ZyA injection. Adoptive transfer of MDSCs to recipient arthritic mice reduced the severity of arthritis compared to that in untreated control mice. Treatment with tofacitinib also ameliorated the progression of arthritis in SKG mice and induced significantly higher numbers of MDSCs and PMN-MDSCs in the BM of these animals. Furthermore, administration of an anti-Gr-1 mAb reduced the antiarthritic effect of tofacitinib in SKG mice. In vitro, tofacitinib facilitated the differentiation of BM cells to MDSCs, and inhibited their differentiation to dendritic cells. CONCLUSION: Tofacitinib facilitates the expansion of MDSCs and ameliorates arthritis in SKG mice.2015年04月, Arthritis & rheumatology (Hoboken, N.J.), 67(4) (4), 893 - 902, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- Soil deposition density maps of gamma-ray emitting radioactive nuclides from the Fukushima Dai-ichi Nuclear Power Plant (NPP) accident were constructed on the basis of results from large-scale soil sampling. In total 10,915 soil samples were collected at 2168 locations. Gamma rays emitted from the samples were measured by Ge detectors and analyzed using a reliable unified method. The determined radioactivity was corrected to that of June 14, 2011 by considering the intrinsic decay constant of each nuclide. Finally the deposition maps were created for (134)Cs, (137)Cs, (131)I, (129m)Te and (110m)Ag. The radioactivity ratio of (134)Cs-(137)Cs was almost constant at 0.91 regardless of the locations of soil sampling. The radioactivity ratios of (131)I and (129m)Te-(137)Cs were relatively high in the regions south of the Fukushima NPP site. Effective doses for 50 y after the accident were evaluated for external and inhalation exposures due to the observed radioactive nuclides. The radiation doses from radioactive cesium were found to be much higher than those from the other radioactive nuclides.2015年01月, Journal of environmental radioactivity, 139, 308 - 319, 英語, 国際誌[査読有り]
- Galectins are a family of animal lectins with conserved carbohydrate-recognition domains that recognize β-galactosides. Despite structural similarities, these proteins have diverse functions in a variety of cellular processes. While a large number of extracellular functions have been demonstrated for galectins, the existence of intracellular functions has been clearly shown for a number of galectins, including regulation of cell growth and apoptosis; these latter functions may not involve glycan binding. There is considerable interest in intracellular regulation by galectins of cell growth and apoptosis, as these are fundamental cellular processes in normal homeostasis. Their dysregulation can cause pathologies such as autoimmune disorders, cancer, and neural degenerative diseases. Here we describe methods that we routinely perform in the laboratory to investigate the role of galectins in cell growth and apoptosis. These include methods for cell isolation, cell maintenance, and genetic manipulations to perturb galectin gene expression, as well as assays for cell growth and apoptosis.2015年, Methods in molecular biology (Clifton, N.J.), 1207, 451 - 63, 英語, 国際誌[査読有り]

- Increased numbers of regulatory T (Treg) cells are found in synovial fluid from patients with rheumatoid arthritis (RASF) compared with peripheral blood. However, Treg cells in RASF have been shown to have a decreased capacity to suppress T cells. Here we phenotypically classified CD4+ T cells in RASF into six subsets based on the expression of CD45RA, CCR7, CD27 and CD28, and demonstrated that the CCR7-CD45RA-CD27+CD28+ TEM subset was significantly increased in synovial fluid compared with peripheral blood. In addition, the proportion of Foxp3+ Treg cells in the CCR7-CD45RA-CD27+CD28+ TEM subset was significantly increased in RASF. Furthermore, most of the Foxp3+ Treg cells in RASF were non-suppressive CD45RA-Foxp3(low) non-Treg cells, and the frequency of the non-Treg cells in the CCR7-CD45RA-CD27+CD28+ TEM subset was significantly increased in RASF. Our findings suggest that the pro-inflammatory environment in RA joints may induce the increase of CD45RA-Foxp3(low) non-Treg cells in synovial fluid.2014年07月, Cellular immunology, 290(1) (1), 96 - 101, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- Human CD4+ T cells can be classified as either naïve, central memory (TCM), or effector memory (TEM) cells. To identify the CD4+ T cell subsets most important in the pathogenesis of rheumatoid arthritis (RA), we phenotypically defined human CD4+ T cells as functionally distinct subsets, and analyzed the distribution and characteristics of each subset in the peripheral blood. We classified CD4+ T cells into six novel subsets based on the expression of CD45RA, CCR7, CD27, and CD28. The CCR7 + CD45RA-CD27 + CD28+ TCM subset comprised a significantly smaller proportion of CD4+ T cells in RA patients compared to healthy controls. The frequency of TNF-α-producing cells in the CCR7-CD45RA-CD27 + CD28+ TEM subset was significantly increased in RA. Furthermore, within the CCR7 + CD45RA-CD27 + CD28+ TCM subset, which was decreased in periperal blood from RA, the proportions of total Foxp3+ Treg cells and CD45RA-Foxp3(high) activated/effector Treg cells were significantly lower in RA patients. Our findings suggest that the increased proportion of TNF-α-producing cells and the decreased proportion of CD45RA-Foxp3(high) activated/effector Treg cells in particular subsets may have critical roles in the pathogenesis of RA.2013年09月, Biochemical and biophysical research communications, 438(4) (4), 778 - 83, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- Gamma-ray pulse height distributions were measured for a fallout sample collected at Ibaraki, Japan, during the Fukushima accident in March 2011. The fallout was collected in a pan of water and then evaporated to dryness on a stainless-steel holder. The sample was measured by a germanium detector three times over a year. In the pulse height distribution of the initial measurement, approximately 140 peaks were observed in the 50-2048 keV energy region. Most of these peaks were either total absorption peaks or sum peaks of Te, I or Cs isotopes. Unlike fallout samples at the past nuclear accidents, nuclides such as Ce and Ru were not detected whereas (110m)Ag was prominently observed. The radioactivity concentration of (137)Cs was determined to be at least 1.4×10(4) Bq m(-2), approximately 14% of which was attributed to rainout.2013年07月, Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine, 77, 56 - 60, 英語, 国際誌[査読有り]
- Interleukin 17-producing helper T (Th17) cells play pathogenic roles in chronic inflammatory and autoimmune diseases, including arthritis, colitis and multiple sclerosis. Th17 cells selectively express the transcription factor RORγt, as well as the cytokine receptors IL-23R and CCR6. Identification of novel Th17 cell-specific molecules may have potential value as diagnostic markers in the above-mentioned inflammatory diseases. To that aim, we carried out a comparative microarray analysis on in vitro differentiated Th1, Th2, Treg and Th17 cells from naïve CD4(+) cells of BALB/c mice. Among a total of one hundred and twenty Th17 cell-specific molecules, twenty-nine were novel cell-surface molecules. Then we revealed that thirteen of them were up-regulated in vivo in inflamed tissues from experimental autoimmune diseases, including spontaneous SKG arthritis, inflammatory bowel disease (IBD) and experimental autoimmune encephalomyelitis (EAE). Next, we analyzed the expression of four membranous molecules, and revealed that podoplanin was expressed highly in the in vitro differentiated Th17 cells. Moreover, at the inflamed synovium of the arthritic SKG mice, most of the accumulating Th17 cells were podoplanin-positive. These results indicate that podoplanin would be a useful Th17 cell marker for diagnosing pathological conditions of autoimmune diseases, including rheumatoid arthritis.2013年06月, Molecular immunology, 54(2) (2), 199 - 207, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- Fibroblast growth factor-1 (FGF1) and FGF2 play a critical role in angiogenesis, a formation of new blood vessels from existing blood vessels. Integrins are critically involved in FGF signaling through crosstalk. We previously reported that FGF1 directly binds to integrin αvβ3 and induces FGF receptor-1 (FGFR1)-FGF1-integrin αvβ3 ternary complex. We previously generated an integrin binding defective FGF1 mutant (Arg-50 to Glu, R50E). R50E is defective in inducing ternary complex formation, cell proliferation, and cell migration, and suppresses FGF signaling induced by WT FGF1 (a dominant-negative effect) in vitro. These findings suggest that FGFR and αvβ3 crosstalk through direct integrin binding to FGF, and that R50E acts as an antagonist to FGFR. We studied if R50E suppresses tumorigenesis and angiogenesis. Here we describe that R50E suppressed tumor growth in vivo while WT FGF1 enhanced it using cancer cells that stably express WT FGF1 or R50E. Since R50E did not affect proliferation of cancer cells in vitro, we hypothesized that R50E suppressed tumorigenesis indirectly through suppressing angiogenesis. We thus studied the effect of R50E on angiogenesis in several angiogenesis models. We found that excess R50E suppressed FGF1-induced migration and tube formation of endothelial cells, FGF1-induced angiogenesis in matrigel plug assays, and the outgrowth of cells in aorta ring assays. Excess R50E suppressed FGF1-induced angiogenesis in chick embryo chorioallantoic membrane (CAM) assays. Interestingly, excess R50E suppressed FGF2-induced angiogenesis in CAM assays as well, suggesting that R50E may uniquely suppress signaling from other members of the FGF family. Taken together, our results suggest that R50E suppresses angiogenesis induced by FGF1 or FGF2, and thereby indirectly suppresses tumorigenesis, in addition to its possible direct effect on tumor cell proliferation in vivo. We propose that R50E has potential as an anti-cancer and anti-angiogenesis therapeutic agent ("FGF1 decoy").2013年, PloS one, 8(2) (2), e57927, 英語, 国際誌[査読有り]
- OBJECTIVES: Recent studies have shown that mycophenolate mofetil (MMF) is similar to intravenous cyclophosphamide (IVC) for the treatment of lupus nephritis (LN), but that treatment response may vary according to location and race/ethnicity. Moreover, no studies have been conducted to compare the efficacy of MMF with that of IVC for a Japanese population. We therefore conducted a retrospective study to clarify the efficacy and safety of MMF compared with that of IVC for induction therapy for active LN, classes III and IV, in a Japanese population of 21 patients, 11 of whom received MMF and 10 IVC. METHODS: The primary endpoint was expressed as the percentage of responders, who in turn were defined as the patients who met complete or partial response criteria according to the European consensus statement. The secondary endpoints comprised the renal activity component and serological activity. RESULTS: The primary endpoint was achieved in nine (81.8 %) patients receiving MMF and in four (40.0 %) receiving IVC, with no significant difference between the two groups (p = 0.081), while there was also no significant difference between them in terms of secondary endpoints. However, the MMF group suffered significantly fewer hematologic toxic effects than the IVC group. CONCLUSIONS: MMF may be used as an alternative to IVC for inducing renal remission of LN in Japanese patients.2013年01月, Modern rheumatology, 23(1) (1), 89 - 96, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- SS-A/Ro52 (Ro52), an autoantigen in systemic autoimmune diseases such as systemic lupus erythematosus and Sjögren's syndrome, has E3 ligase activity to ubiquitinate proteins that protect against viral infection. To investigate Ro52's role during stress, we transiently knocked it down in HeLa cells by siRo52 transfection. We found that Ro52(low) HeLa cells were significantly more resistant to apoptosis than wild-type HeLa cells when stimulated by H(2)O(2)- or diamide-induced oxidative stress, IFN-α, IFN-γ and anti-Fas antibody, etoposide, or γ-irradiation. Furthermore, Ro52-mediated apoptosis was not influenced by p53 protein level in HeLa cells. Depleting Ro52 in HeLa cells caused Bcl-2, but not other Bcl-2 family molecules, to be upregulated. Taken together, our data showed that Ro52 is a universal proapoptotic molecule, and that its proapoptotic effect does not depend on p53, but is exerted through negative regulation of the anti-apoptotic protein Bcl-2. These findings shed light on a new physiological role for Ro52 that is important to intracellular immunity.2012年01月, Biochemical and biophysical research communications, 417(1) (1), 582 - 7, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- Serum 1,3-β-d-glucan (BG) assay may be helpful as a marker for the diagnosis of Pneumocystis jiroveci pneumonia (PJP) and invasive fungal infection (IFI). We conducted a systematic review to assess the diagnostic accuracy of this assay. We searched MEDLINE, Web of Science, Cochrane Collaboration databases, Ichushi-Web, reference lists of retrieved studies, and review articles. Our search included studies of serum BG assay that used (i) positive cytological or direct microscopic examination of sputum or bronchoalveolar lavage fluid for PJP and (ii) European Organization for Research and Treatment of Cancer or similar criteria for IFI as a reference standard and provided data to calculate sensitivity and specificity. Only major fungal infections such as invasive candidiasis and invasive aspergillosis were included in the IFI group. Twelve studies for PJP and 31 studies for IFI were included from January 1966 to November 2010. The pooled sensitivity, specificity, diagnostic odds ratio (DOR), and area under the summary receiver operating characteristic curve (AUC-SROC) for PJP were 96% (95% confidence interval [95% CI], 92% to 98%), 84% (95% CI, 83% to 86%), 102.3 (95% CI, 59.2 to 176.6) and 0.96 (95% CI, 0.94 to 0.99), respectively. No heterogeneity was found. For IFI, the values were 80% (95% CI, 77% to 82%), 82% (95% CI, 81% to 83%), 25.7 (95% CI, 15.0 to 44.1), and 0.88 (95% CI, 0.82 to 0.93). Heterogeneity was significant. The diagnostic accuracy of the BG assay is high for PJP and moderate for IFI. Because the sensitivity for PJP is particularly high, the BG assay can be used as a screening tool for PJP.2012年01月, Journal of clinical microbiology, 50(1) (1), 7 - 15, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- This case report describes findings in a 61-year-old woman who manifested scleritis, small pulmonary nodules, otitis media, periaortitis, and progressive epidural spinal tumor, associated with elevated serum myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA) levels. She was clinically diagnosed with Wegener's granulomatosis, although vasculitis was not diagnosed due to the lack of typical histological findings. We discuss the differential diagnosis in this patient, and the association of MPO-ANCA with periaortitis or epidural spinal tumor.2011年12月, Modern rheumatology, 21(6) (6), 678 - 83, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- Galectin-3 is highly expressed in epithelial cells including keratinocytes and is involved in the pathogenesis of inflammatory skin diseases by affecting the functions of immune cells. For example, galectin-3 can contribute to atopic dermatitis (AD) by promoting polarization toward a Th2 immune response by regulating dendritic cell (DC) and T cell functions. In addition, galectin-3 may be involved in the development of contact hypersensitivity by regulating the migratory capacity of antigen presenting cells. Galectin-3 may act as a regulator of epithelial tumor progression and development through various signaling pathways, such as inhibiting keratinocyte apoptosis through regulation of the activation status of extracellular signal-regulated kinase (ERK) and activated protein kinase B (AKT). Galectin-3 is detected at different stages of melanoma development. In contrast, a marked decrease in the expression of galectin-3 is observed in non-melanoma skin cancers, such as squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). Galectin-3 may play an important role in tumor cell growth, apoptosis, cell motility, invasion, and metastasis. Galectin-3 may be a novel therapeutic target for a variety of skin diseases.2011年11月, Journal of dermatological science, 64(2) (2), 85 - 91, 英語, 国際誌[査読有り]

- The objective of this study is to clarify the characteristics and imaging results of Japanese patients with giant cell arteritis (GCA). Eight patients with biopsy-proven GCA were enrolled. Their clinical data and imaging results were retrospectively examined from their medical records. All the patients met the criteria for the classification of GCA by the American College of Rheumatology. Although the clinical manifestations are similar to those previously reported, none of the eight patients presented ocular symptoms, and half of them presented jaw claudication. Ultrasonography (US) of temporal artery showed the halo sign in all the patients. Fluorodeoxyglucose positron emission tomography (FDG-PET) was performed in four patients and indicated the presence of aortitis of the patients. US is a quick and noninvasive test to detect inflammation of temporal artery, and FDG-PET is very helpful for early diagnosis of aortitis in GCA. Awareness of the disease and appropriate imaging tests will result in diagnosis of GCA.2011年08月, Modern rheumatology, 21(4) (4), 391 - 6, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- INTRODUCTION: The purpose of this study was to elucidate the effects of histone deacetylase inhibition on the phenotype and function of dendritic cells and on arthritis in SKG mice. METHODS: Arthritis was induced in SKG mice by zymosan A injection. Trichostatin A, a histone deacetylase inhibitor, was administered and its effects on arthritis were evaluated by joint swelling and histological evaluation. Interleukin-17 production in lymph node cells was determined by an enzyme-linked immunosorbent assay (ELISA). Foxp3 expression in lymph node cells and the phenotypes of splenic dendritic cells were examined by fluorescence-activated cell sorting (FACS). Bone marrow-derived dendritic cells (BM-DC) were generated with granulocyte macrophage colony-stimulating factor. The effects of trichostatin A on cell surface molecules, cytokine production, indoleamine 2,3-dioxygenase (IDO) expression and T cell stimulatory capacity were examined by FACS, ELISA, quantitative real-time polymerase chain reaction and Western blot, and the allo-mixed lymphocyte reaction, respectively. RESULTS: Trichostatin A, when administered before the onset of arthritis, prevented SKG mice from getting arthritis. Trichostatin A treatment also showed therapeutic effects on arthritis in SKG mice, when it was administered after the onset of arthritis. Trichostatin A treatment reduced Th17 cells and induced regulatory T cells in lymph node, and also decreased co-stimulatory molecule expression on splenic dendritic cells in vivo. In vitro, trichostatin A markedly suppressed zymosan A-induced interleukin-12 and interleukin-6 production by BM-DC and up-regulated IDO expression at mRNA and protein levels. Trichostatin A-treated BM-DC also showed less T cell stimulatory capacity. CONCLUSIONS: Histone deacetylase inhibition changes dendritic cells to a tolerogenic phenotype and ameliorates arthritis in SKG mice.2011年05月, Arthritis research & therapy, 13(3) (3), R77, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- [Usefulness of anti-SS-A/Ro antibody measurement based on fluorescence enzyme immunoassay with Ro60 and Ro52 antigen].OBJECTIVE: Anti-SS-A/Ro antibody is commonly found in the sera of patients with rheumatic disease. The antigenic components of SS-A/Ro are 60kD. and 52kD-Ro protein. Only anti-60kD SS-A/Ro antibody is detected by commonly used tests in clinical laboratories. "UniCAP EliA SS-A/Ro" is a new reagent using fluorescence enzyme immunoassay (FEIA) based on a mixture of both 60kD- and 52kD-Ro antigens. We evaluated the efficacy of detecting both anti-60kD and 52kD SS-A/Ro antibodies. PATIENTS AND METHODS: We collected sera from 264 rheumatic disease patients and 106 healthy subjects. Anti-SS-A/Ro antibodies were measured by the new reagent along with conventional method. Anti-52kD and 60kD SS-A/Ro antibodies were measured by ELISA kit in rheumatic disease patients. RESULTS: Anti-SS-A/Ro antibody levels were higher in patients with Sjögren's syndrome than those with SLE or RA. The prevalence of anti-SS-A/Ro antibody in rheumatic disease patients and healthy subjects were comparable with the conventional method, and patients with Sjögren's syndrome had highest prevalence of anti-SS-A/Ro antibody. Concordance rate between EliA and conventional method, and EliA and DID, were 96.6% and 94.3%, respectively. ELISA analysis revealed that patients with Sjögren's syndrome had anti-52kD SS-A/Ro antibody at high rates, while anti-60kD SS-A/Ro antibody was widely found in rheumatic disease patients. Three patients were positive only for anti-52kD SS-A/Ro antibody. CONCLUSION: Taken together, "UniCAP EliA SS-A/Ro" is useful as a screening test for anti-SS-A/Ro antibodies.2011年04月, Rinsho byori.

- OBJECTIVE: To clarify the role of platelet-derived microparticles (PDMP), which are small vesicles with thrombotic and immunological properties, in systemic lupus erythematosus (SLE), systemic sclerosis (SSc), dermatomyositis/polymyositis (PM/DM), and mixed connective tissue disease (MCTD). METHODS: Plasma levels of PDMP were measured by ELISA, and compared among patients with one of the 4 diseases. Association of PDMP levels with clinical characteristics and medication of the patients was also examined. RESULTS: PDMP levels were higher in patients with MCTD and SSc than in controls. Multiple linear regression analysis revealed that patients with Raynaud's phenomenon (RP) showed higher PDMP levels than those without. PDMP levels in individual patients did not fluctuate significantly over several months. CONCLUSION: PDMP level is associated with MCTD, SSc, and RP, and could be a novel marker for RP.2011年04月, The Journal of rheumatology, 38(4) (4), 680 - 4, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- A 63-year-old man was admitted to our hospital with a complaint of right lateroabdominal pain. He was diagnosed with metastatic colon cancer, and then developed multiple brain embolic infarctions 7 days after admission. Transesophageal echocardiography showed that mobile, echo-dense masses were attached to the anterior and posterior mitral valve leaflet. Furthermore, there was a thrombus in the left auricular appendage despite sinus rhythm. These findings led to a diagnosis of suspected infectious endocarditis with subsequent multiple brain infarctions. The patient's general condition worsened and he died 13 days after admission. An autopsy was performed, and, while poorly differentiated cancer was observed in multiple organs, no primary tumor could be identified. Histological analysis showed that the masses of the mitral valve consisted mainly of fibrin without bacteria or oncocytes. This patient was therefore diagnosed with nonbacterial thrombotic endocarditis associated with cancer of unknown origin complicated with thrombus in the left auricular appendage.2011年02月, Cardiovascular ultrasound, 9, 8 - 8, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- The C-terminal domain of the fibrinogen gamma chain (gammaC) has been shown to bind to the integrins alphaIIbbeta3, alphaMbeta2 and alphaVbeta3. It has also been reported that a peptide derived from the alphaMbeta2-binding site of gammaC can suppress an animal model of multiple sclerosis, experimental autoimmune encephalomyelitis (EAE). Here we have truncated gammaC at position 399 to remove the prothrombotic alphaIIbbeta3-binding site. We show that this truncated version of gammaC, termed gammaC399tr, can bind to activated T cells. In addition, T cells incubated with gammaC399tr secreted less IFN-gamma when stimulated with antigen and APC; however, cytokine secretion was unaltered when T cells were stimulated non-specifically with a mixture of anti-CD3 and anti-CD28 antibodies. Thus, only antigen-dependent T cell activation is inhibited by gammaC399tr. When administered intraperitoneally, gammaC399tr potently inhibited actively induced EAE and reversed ongoing disease. We hypothesize that the ability of gammaC399tr to inhibit autoreactive immune responses is a result of its ability to bind integrins. This activity was not solely dependent on the alphaMbeta2 integrin-binding site. When polyalanine was substituted for the alphaMbeta2-binding site, the resulting gammaC390polyA was still able to inhibit EAE. To our knowledge, this is the first demonstration that T cells can bind to fibrin (ogen), an important extracellular matrix protein that is deposited at sites of inflammation. Our results also identify gammaC399tr as a novel therapeutic molecule.2010年06月, Journal of autoimmunity, 34(4) (4), 453 - 9, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- BACKGROUND: Crosstalk between integrins and FGF receptors has been implicated in FGF signaling, but the specifics of the crosstalk are unclear. We recently discovered that 1) FGF1 directly binds to integrin alphavbeta3, 2) the integrin-binding site and FGF receptor (FGFR) binding site are distinct, and 3) the integrin-binding-defective FGF1 mutant (R50E) is defective in inducing FGF signaling although R50E still binds to FGFR and heparin and induces transient ERK1/2 activation. PRINCIPAL FINDINGS: We tested if excess R50E affect DNA synthesis and cell survival induced by WT FGF1 in BaF3 mouse pro-B cells expressing human FGFR1. R50E suppressed DNA synthesis and cell proliferation induced by WT FGF1. We tested if WT FGF1 and R50E generate integrin-FGF1-FGFR ternary complex. WT FGF1 induced ternary complex formation (integrin-FGF-FGFR1) and recruitment of SHP-2 to the complex in NIH 3T3 cells and human umbilical endothelial cells, but R50E was defective in these functions. It has been reported that sustained ERK1/2 activation is integrin-dependent and crucial to cell cycle entry upon FGF stimulation. We thus determined the time-course of ERK1/2 activation induced by WT FGF1 and R50E. We found that WT FGF1 induced sustained activation of ERK1/2, but R50E was defective in this function. CONCLUSIONS/SIGNIFICANCE: Our results suggest that 1) R50E is a dominant-negative mutant, 2) Ternary complex formation is involved in FGF signaling, 3) The defect of R50E to bind to integrin may be directly related to the antagonistic action of R50E. Taken together, these results suggest that R50E has potential as a therapeutic in cancer.2010年04月, PloS one, 5(4) (4), e10273, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- It has been proposed that ligand occupancy of integrin alphavbeta3 with extracellular matrix ligands (e.g. vitronectin) plays a critical role in insulin-like growth factor-1 (IGF-1) signaling. We found that expression of alphavbeta3 enhanced IGF-1-induced proliferation of Chinese hamster ovary cells in serum-free conditions (in the absence of vitronectin). We hypothesized that the direct integrin binding to IGF-1 may play a role in IGF-1 signaling. We demonstrated that alphavbeta3 specifically and directly bound to IGF-1 in cell adhesion, enzyme-linked immunosorbent assay-type binding, and surface plasmon resonance studies. We localized the amino acid residues of IGF-1 that are critical for integrin binding by docking simulation and mutagenesis. We found that mutating two Arg residues at positions 36 and 37 in the C-domain of IGF-1 to Glu (the R36E/R37E mutation) effectively reduced integrin binding. Interestingly, although the mutant still bound to IGF1R, it was defective in inducing IGF1R phosphorylation, AKT and ERK1/2 activation, and cell proliferation. Furthermore wild type IGF-1 mediated co-precipitation of alphavbeta3 and IGF1R, whereas the R36E/R37E mutant did not, suggesting that IGF-1 mediates the interaction between alphavbeta3 and IGF1R. These results suggest that the direct binding to IGF-1 to integrin alphavbeta3 plays a role in IGF-1 signaling through ternary complex formation (alphavbeta3-IGF-IGF1R), and integrin-IGF-1 interaction is a novel target for drug discovery.2009年09月, The Journal of biological chemistry, 284(36) (36), 24106 - 14, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- Galectin-3 belongs to a family of beta-galactoside-binding animal lectins expressed in several cell types, including epithelial and immune cells. To establish the role of galectin-3 in the development of allergic skin inflammation, we compared inflammatory skin responses of galectin-3-deficient (gal3(-/-)) and wild-type (gal3(+/+)) mice to epicutaneous sensitization with ovalbumin (OVA). OVA-treated gal3(-/-) mice exhibited markedly reduced epidermal thickening, lower eosinophil infiltration, and lower serum IgE levels compared with gal3(+/+) mice. The former evoked lower interleukin-4, but higher interferon-gamma, mRNA expression at OVA-treated skin sites. Moreover, gal3(-/-) splenocytes from OVA-sensitized mice secreted more interleukin-12 compared with gal3(+/+) splenocytes. In addition, antigen presentation by gal3(-/-) dendritic cells to T cells in vitro were T helper cell (Th1)-polarized relative to presentation by gal3(+/+) dendritic cells. When exposed to OVA, recipients engrafted with T cells from gal3(-/-) OVA-specific T cell receptor transgenic mice developed significantly reduced dermatitis and a markedly lower Th2 response compared with recipients of comparable gal3(+/+) T cells. We conclude that galectin-3 is critical for the development of inflammatory Th2 responses to epicutaneously administered antigens; in its absence, mice develop a Th1-polarized response. This regulatory effect of galectin-3 on Th development is exerted at both the dendritic cell and T cell levels. Our studies suggest that galectin-3 may play an important role in the acute phase of human atopic dermatitis.2009年03月, The American journal of pathology, 174(3) (3), 922 - 31, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- Keratinocytes undergo apoptosis in a variety of physiological and pathological conditions. Galectin-3 is a member of a family of beta-galactoside-binding animal lectins expressed abundantly in keratinocytes and other epithelial cells. Here, we have studied the regulatory role of galectin-3 in keratinocyte apoptosis by using cells from gene-targeted galectin-3 null (gal3(-/-)) mice. We showed that galectin-3 mRNA was transiently upregulated in ultraviolet-B (UVB)-irradiated wild-type keratinocytes. We found that gal3(-/-) keratinocytes were significantly more sensitive to apoptosis induced by UVB as well as various other stimuli, both in vitro and in vivo, than wild-type cells. Moreover, we demonstrated that increased apoptosis in gal3(-/-) keratinocytes was attributable to higher extracellular signal-regulated kinase (ERK) activation and lower AKT activation after UVB irradiation. We conclude that endogenous galectin-3 is an anti-apoptotic molecule in keratinocytes functioning by suppressing ERK activation and enhancing AKT activation and may play a role in the development of apoptosis-related skin diseases.2008年10月, The Journal of investigative dermatology, 128(10) (10), 2403 - 11, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- Secretory phospholipase A2 group IIA (sPLA2-IIA) plays an important role in the pathogenesis of inflammatory diseases. Catalytic activity of this enzyme that generates arachidonic acid is a major target for development of anti-inflammatory agents. Independent of its catalytic activity, sPLA2-IIA induces pro-inflammatory signals in a receptor-mediated mechanism (e.g. through the M-type receptor). However, the M-type receptor is species-specific: sPLA2-IIA binds to the M-type receptor in rodents and rabbits, but not in human. Thus sPLA2-IIA receptors in human have not been established. Here we demonstrated that sPLA2-IIA bound to integrin alphavbeta3 at a high affinity (K(D)=2 x 10(-7) M). We identified amino acid residues in sPLA2-IIA (Arg-74 and Arg-100) that are critical for integrin binding using docking simulation and mutagenesis. The integrin-binding site did not include the catalytic center or the M-type receptor-binding site. sPLA2-IIA also bound to alpha4beta1. We showed that sPLA2-IIA competed with VCAM-1 for binding to alpha4beta1, and bound to a site close to those for VCAM-1 and CS-1 in the alpha4 subunit. Wild type and the catalytically inactive H47Q mutant of sPLA2-IIA induced cell proliferation and ERK1/2 activation in monocytic cells, but the integrin binding-defective R74E/R100E mutant did not. This indicates that integrin binding is required, but catalytic activity is not required, for sPLA2-IIA-induced proliferative signaling. These results suggest that integrins alphavbeta3 and alpha4beta1 may serve as receptors for sPLA2-IIA and mediate pro-inflammatory action of sPLA2-IIA, and that integrin-sPLA2-IIA interaction is a novel therapeutic target.2008年09月, The Journal of biological chemistry, 283(38) (38), 26107 - 15, 英語, 国際誌[査読有り]研究論文(学術雑誌)
- Integrins play a role in fibroblast growth factor (FGF) signaling through cross-talk with FGF receptors (FGFRs), but the mechanism underlying the cross-talk is unknown. We discovered that FGF1 directly bound to soluble and cell-surface integrin alphavbeta3 (K(D) about 1 microm). Antagonists to alphavbeta3 (monoclonal antibody 7E3 and cyclic RGDfV) blocked this interaction. alphavbeta3 was the predominant, if not the only, integrin that bound to FGF1, because FGF1 bound only weakly to several beta1 integrins tested. We presented evidence that the CYDMKTTC sequence (the specificity loop) within the ligand-binding site of beta3 plays a role in FGF1 binding. We found that the integrin-binding site of FGF1 overlaps with the heparin-binding site but is distinct from the FGFR-binding site using docking simulation and mutagenesis. We identified an FGF1 mutant (R50E) that was defective in integrin binding but still bound to heparin and FGFR. R50E was defective in inducing DNA synthesis, cell proliferation, cell migration, and chemotaxis, suggesting that the direct integrin binding to FGF1 is critical for FGF signaling. Nevertheless, R50E induced phosphorylation of FGFR1 and FRS2alpha and activation of AKT and ERK1/2. These results suggest that the defect in R50E in FGF signaling is not in the initial activation of FGF signaling pathway components, but in the later steps in FGF signaling. We propose that R50E is a useful tool to identify the role of integrins in FGF signaling.2008年06月, The Journal of biological chemistry, 283(26) (26), 18066 - 75, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- Is SS-A/Ro52 a hydrogen peroxide-sensitive signaling molecule?SS-A/Ro52 (Ro52) protein is one of the targets of autoantibodies in Sjogren's syndrome and systemic lupus erythematosus. Ro52 structurally belongs to the RING-B-box/coiled-coil family, which appears to carry out diverse functions, but the physiological function of Ro52 remains largely unknown. Here, the authors demonstrate that hydrogen peroxide but not other oxidative stressors induced translocation of Ro52 protein from the cytoplasm to the nucleus and this phenomenon was attenuated by inhibition of MAP kinases, ERK in particular. These findings raise the possibility that SS-A/Ro52 may function as a hydrogen peroxide-selective, oxidative stress-sensitive signaling molecule that is activated via the MAP kinase pathway.2007年03月, Antioxidants & redox signaling, 9(3) (3), 385 - 91, 英語, 国際誌[査読有り]
- The COOH-terminal globular domain of fibrinogen gamma chain suppresses angiogenesis and tumor growth.Fibrinogen is a major plasma protein (350 kDa) that induces proliferative signals by serving as a scaffold to support the binding of growth factors and to promote the cellular responses of adhesion, proliferation, and migration during wound healing, angiogenesis, and tumor growth. Fibrin(ogen) degradation products generated during fibrinolysis are implicated in tissue injury. The fibrinogen gamma chain has a COOH-terminal globular domain (gamma C, residues 151-411 of the gamma chain, 30 kDa) to which several integrin cell adhesion receptors (e.g., platelet alpha(IIb)beta(3), endothelial alpha(v)beta(3), and leukocyte alpha(M)beta(2)) bind. Integrins play a critical role in signal transduction from fibrin(ogen). We found that gamma C and its truncation mutant (designated gamma C399tr), with a deletion of the COOH-terminal 12 residues, induced apoptosis of endothelial cells and blocked tube formation of endothelial cells. DLD-1 human colon cancer cells that secrete gamma C or gamma C399tr grew at similar levels in vitro but grew much slower in vivo than mock-transfected cells. The recombinant purified gamma C399tr fragment markedly suppressed tumor growth, development of intratumoral vasculature, and tumor metastasis in vivo in the highly metastatic Met-1 breast cancer model. The determinant responsible for binding to endothelial cells is cryptic in native fibrinogen but is exposed in gamma C and gamma C399tr. These results suggest that fibrinogen has a novel cryptic determinant, which can exert apoptosis-inducing activity on endothelial cells when exposed, and polypeptides containing this determinant have therapeutic potential.2006年10月, Cancer research, 66(19) (19), 9691 - 7, 英語, 国際誌[査読有り]研究論文(学術雑誌)

- Determination of detection efficiency curves of HPGe detectors on radioactivity measurement of volume samples.An efficiency calibration method has been developed to measure radioactivity of volume samples with HPGe detectors. The method has two main procedures. One is a point-source calibration at a representative point near the detector. The position of the representative point is determined by Monte Carlo simulations. The other is correction for absorption by a sample matrix and a sample container. This paper presents application of the method for obtaining efficiency curves for volume samples in the energy range from 22 to 1836 keV. In addition to the standard volume sources of cement and water matrices, measurement was made with some kinds of environmental samples that are often used in environmental monitoring for radiation control works. The composition of the environmental sample was determined by elemental analysis. For these samples, measured absorption correction factors were compared with those by the Monte Carlo simulations. As a result, detection efficiency curves were obtained with good accuracy for variety types of volume samples.2004年12月, Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine, 61(6) (6), 1383 - 90, 英語, 国際誌[査読有り]

- [Pathological roles of oxidative stress in autoimmune diseases].Autoimmune diseases are complex diseases in which both genetic and environmental factors are involved. Excessive oxidative stress is thought to have an important role in the pathogenesis of autoimmune diseases by enhancing the inflammation, inducing apoptotic cell death, and breaking down the immunological tolerance. When the state of oxidative stress was investigated in patients with rheumatoid arthritis(RA), systemic lupus erythematosus(SLE), and Sjögren's syndrome(SS) by oxidative stress profile(OSP), most subjects were in excessive oxidative stress or in defective antioxidant potentials. The thioredoxin(TRX) level in peripheral blood was significantly higher in these patients than in healthy subjects. Urinary excretion of 8-hydroxy-guanosine was also significantly increased in these patients compared with healthy subjects. We have proven that oxidative stress as well as UV irradiation induced the expression of SS-A/Ro52 autoantigen on the cell surface of keratinocytes. Oxidative stress not only injures the cellular components but also induces cellular responses, including apoptosis and gene activation. We also identified that GSTM1 null genotype was a candidate gene for susceptibility to SS and was associated with SS-A/Ro autoantibody production. In the synovial fluid of RA patients, TRX was abundantly detected and was produced in the lining layer of synovial tissue, indicating that TRX might protect synovial tissue from oxidative stress. Infections, UV irradiation, coldness, and emotional stress have been clinically well known as developing and exacerbating factors for autoimmune diseases. These environmental factors are closely related to oxidative stress. It is very important to develop reliable test methods to detect the state of oxidative stress and antioxidants.2003年02月, Rinsho byori.

- Oxidative stress mediates cell surface expression of SS-A/Ro antigen on keratinocytes.Exposure to ultraviolet radiation exacerbates the skin lesions of autoimmune diseases, and is known to induce cell surface expression of SS-A/Ro antigen on keratinocytes in vitro. Following up on recent reports on ultraviolet-B (UVB)-induced oxidative stress, we examined the role of oxidative stress in the surface expression of SS-A/Ro antigen on human keratinocytes. First, the exclusive induction by UVB irradiation of the 52-kDa protein (Ro52) but not of the 60-kDa protein (Ro60) of SS-A/Ro antigen was demonstrated by means of indirect immunofluorescence. The surface expression of Ro52 induced by UVB irradiation was concentration-dependently inhibited by N-acetyl-L-cysteine, an antioxidant. Furthermore, surface expression of Ro52 was similarly induced by diamide, a chemical oxidant. We next used Hoechst 33342 staining and the TUNEL assay to demonstrate that a low dose (20 mJ/cm(2)) of UVB did not induce apoptosis but induced the surface expression of Ro52. Moreover, zVAD-fmk, a pan-caspase inhibitor, did not inhibit UVB-induced surface expression of Ro52 even at a high dose (200 mJ/cm(2)) of UVB, which was sufficient to induce apoptosis in keratinocytes in the absence of zVAD-fmk. Taken together, we concluded that UVB-induced surface expression of Ro52 on keratinocytes is mediated by oxidative stress through a pathway other than apoptosis.2002年05月, Free radical biology & medicine, 32(10) (10), 1006 - 16, 英語, 国際誌[査読有り]

- 日本学術振興会, 科学研究費助成事業 基盤研究(C), 基盤研究(C), 神戸大学, 2019年04月01日 - 2022年03月31日関節リウマチ特異的ノンコーディングRNA相互作用に関する研究われわれは、ヒト関節リウマチ(RA)滑膜細胞で特異的に発現が減少するmiRNAとしてmiR-124aを発見し、AIAモデルで関節局所にラット・ホモログmiR-124前駆体を投与した結果、関節炎の抑制効果を認めるという成果を得た。miR-124aは、軟骨細胞、破骨細胞、造骨細胞の増殖分化に与えることが明らかになっており、RA病態に重要な分子として、我々はmiR-124aの治療応用について研究を進めている。近年がん研究の領域を中心にmiR-124aと相互作用するlncRNAの報告が見られるようになり、またlncRNAが臓器特異的に発現するという特性が指摘されている。本研究はヒトRAにおいて滑膜細胞や炎症細胞におけるmiRNAと長鎖ノンコーディングRNA(lncRNA)の相互作用に着目し、RAの病態におけるlncRNAの役割を明らかにすることを目的とする。RA病態におけるmiRNAの役割については研究されつつあるが、自己免疫疾患、なかんずくRAにおけるlncRNA発現の意義は不明であり、miRNAとlncRNAの相互作用については未知のりょうきであるとから、本研究はこれに着目している。miRNAとlncRNAの相互作用に着目した本研究は、RA病態研究や治療応用に新しい展望を開くものである。 本研究では、RAの病態におけるmiR-124aとlncRNAの相互作用をRA患者由来滑膜線維芽細胞(RAFLS)の機能抑制、ラット・AIAへの効果という視点から解析し、lncRNA-miRNA相関を標的とした新しいRA診断・治療法の可能性を探る。2019年度は、miR-124aに結合するlncRNA(lncRNA-X)を同定する作業に着手した。

- 日本学術振興会, 科学研究費助成事業 奨励研究, 奨励研究, 神戸大学, 2019年 - 2019年近年、関節リウマチ(RA)の病態にエクソソームが関与していることが明らかになっている。我々がこれまで同定したRA新規エクソソームバイオマーカーの候補分子について、今回、関節炎モデルマウスで検証した。その結果、関節炎モデルマウスとRA患者の血液中で1種類の候補分子を検出できたが、種々の理由からRA新規エクソソームバイオマーカーへの応用が困難であった。
- 日本学術振興会, 科学研究費助成事業 奨励研究, 奨励研究, 神戸大学, 2019年 - 2019年梅毒は血清中の梅毒抗体を測定し診断している。血清学的検査法にはカルジオリピンを抗原とする方法(RPR)とトレポネーマ抗原を用いる方法(TP抗体)がある。また、これらの診断試薬は多数市販されているが、各診断試薬で反応性は異なりその程度は明らかにされていなかった。そのため、臨床診断を基準として、各診断薬の反応性を違いを比較研究するとRPR自動化定量法のメーカー間差は少なかったが生物学的偽陽性はいずれの方法においても確認できた。FTA-ABSは感度が悪く、TP抗体は定量法が望ましく、定量値は治療後モニタリングに使用できる可能性があった。
