目的研究乌帕替尼对氧糖剥夺再复氧(OGD/R)后BV2小胶质细胞极化及炎症的影响,并探讨其作用机制。方法实验分对照组、OGD组和乌帕替尼组3组。BV2细胞经OGD/R处理后,噻唑蓝试剂(MTT)检测细胞生存率,划痕实验观察细胞迁移能力,实时荧光定量多聚核苷酸链式反应(qPCR)检测BV2细胞M1型极化标志物(CD11b、CD32、iNOS)和M2型极化标志物(Arg-1、IL-10、CD206)的mRNA水平,酶联免疫吸附测定(ELISA)检测培养基中IL-1β、IL-6、TNF-α含量,蛋白质印迹法(Western Blot)检测JAK1/STAT6通路相关蛋白表达水平。结果乌帕替尼能增加OGD/R后BV2细胞的生存率(P<0.05),能减少BV2细胞向M1型极化(P<0.05)。乌帕替尼可明显降低OGD/R诱导的BV2细胞的迁移能力(P<0.05),减少OGD/R诱导BV2细胞分泌的炎症因子:IL-1β、IL-6、TNF-α(P<0.05)。乌帕替尼提高共培养PC12细胞的生存率(P<0.05)。乌帕替尼可显著抑制由OGD/R诱导激活BV2细胞p-JAK1和p-STAT6蛋白的表达水平(P<0.05)。结论乌帕替尼可减少OGD/R诱导BV2细胞向M1型极化和减少炎症反应,与JAK1/STAT6通路有关。  相似文献

Introduction: Tofacitinib and baricitinib have recently been approved as second-line treatments for Rheumatoid arthritis (RA) though their maximum expected efficacy may be limited by dose-related toxicities. Upadacitinib selectively inhibits Janus Kinase 1 (JAK1) which could potentially reduce JAK2 and JAK3-related side effects.

Areas covered: In this paper, we review a newly developed oral selective JAK inhibitor, upadacitinib for the treatment of RA. The doses of upadacitinib extended-release 15 and 30 mg daily selected in phase III RA studies have shown a near-maximum efficacy in phase II studies. Upadacitinib inhibited radiographic progression and displayed rapid and sustained clinical and functional efficacy in RA when in combination with methotrexate (MTX), upadacitinib was superior to placebo in MTX-Inadequate Responders (IRs) and biologic disease modifying antirheumatic drugs-IRs while as monotherapy, it was superior to MTX in MTX-IRs and MTX-naïve patients. Upadacitinib was superior to adalimumab using ACR70, reduction of pain-VAS and improvement of HAQ-DI. The comparison with abatacept is still ongoing.

Expert commentary: Upadacitinib has displayed a rapid and favorable efficacy profile in RA but despite being a selective JAK1 inhibitor appears to have a similar safety profile to less-selective Jakinibs. Longer term safety data are awaited.  相似文献

Upadacitinib is a selective Janus kinase-1 (JAK-1) inhibitor that has been shown in clinical trials to be effective for the treatment of moderate-to-severe atopic dermatitis (AD). This study aimed to evaluate the real-world experience of patients with AD treated with upadacitinib in a single-centre Australian cohort. Our study revealed a higher propensity for herpetic infections compared with previous randomised controlled trials (RCTs).  相似文献
