CD4＋调节性T细胞及其在类风湿关节炎中的研究进展

调节性T细胞（Treg）是一群具有免疫调节功能的T细胞亚群，其功能异常可导致多种自身免疫病。类风湿关节炎（RA）是一种主要累及周围关节的多系统炎症性自身免疫病，多种免疫细胞与其发病存在密切关联。本文回顾近年来有关CD4^＋Treg及其在RA中的研究进展情况，为进一步研究RA的发病机制和治疗打下基础。     

IL-8在强直性脊柱炎活动期的表达与意义

目的 探讨趋化因子IL-8在强直性脊柱炎(AS)活动期的表达及意义。方法 通过cDNA微阵列及RT-PCR技术检测活动期AS患者和对照组[健康志愿者、类风湿关节炎(RA)及膝关节外伤患者]的外周血、关节液中单个核细胞和滑膜细胞IL-8的表达．比较AS患者组与各对照组IL-8表达情况的差异。结果 在活动期AS患者外周血单个核细胞(PBMC)或关节液单个核细胞(SFMC)中IL-8的表达均明显高于健康志愿者PBMC中的表达,在RA患者PBMC中IL-8的表达亦高于健康志愿者PBMC中的表达．关节滑膜细胞IL-8的表达水平在AS患者也明显高于膝关节外伤患者。结论 IL-8在活动期AS中存在高表达,可能是AS的一种重要的炎症介质,介导AS滑膜甚至其他受累组织炎症的发生和发展。

Abnormal high-expression of CD154 on T lymphocytes of ankylosing spondylitis patients is down-regulated by etanercept treatment

The pathogenesis of ankylosing spondylitis (AS) still remains an enigma. Although some studies have indicated the importance of T-cells and proinflammatory cytokines in the pathogenesis of the AS, it is still unknown whether co-stimulatory molecule CD154 participates in the pathogenesis of AS and how its level changes during the anti-TNF-α treatment of AS. This study is performed to evaluate the expression of CD154 in peripheral blood T-lymphocytes of patients with AS and observe the change of CD154 in etanercept-treated AS patient. We collected the peripheral blood and clinical data from 66 AS, 30 rheumatoid arthritis (RA) patients, and 30 healthy controls. Thirty-nine active AS patients were enrolled in a randomized double-blind placebo-controlled trial. We followed up 37 cases that fulfilled the ASAS20 response criteria after they finished etanercept treatment till week 48. The percentage of CD3+CD154+ in peripheral blood lymphocytes was evaluated by flow cytometry. We found that CD154 expression in AS patients was significantly higher than that in healthy volunteers and RA patients (both P < 0.001). The expressions of CD154 in AS patients at active stage or with peripheral joint involvement were significantly higher than those at stable stage or with axial involvement alone (P = 0.005 and 0.044, respectively). The expression of CD154 decreased in AS patients treated with etanercept compared with patients treated with placebo at week 6 (P < 0.001). Compared with healthy volunteers, the expression of CD154 in 16 AS patients who relapsed after finishing etanercept treatment was elevated again (P = 0.012). These findings show that co-stimulatory molecule CD154 is overexpressed on T-lymphocytes in peripheral blood of AS patients and can be down-regulated by etanercept treatment, which suggest that CD154 might be involved in the inflammatory evolvement of AS and might be a potential biomarker to monitor AS disease activity and the effect of etanercept treatment.
