目的探讨Tregs细胞CCR4、CCR6受体在类风湿关节炎(RA)患者发病时的意义。方法选择45例活动期RA患者(RA组)及30例健康体检者(对照组),从外周血分离单个核细胞(PBMC),采用流式细胞分析法检测RA患者外周血中CD4+Foxp3+细胞(Tregs)占比及其该类细胞上CCR4、CCR6的表达水平,并对Tregs上CCR4、CCR6水平与RA临床活动指标进行相关性分析。结果与对照组比较,RA活动期患者外周血Tregs细胞数量明显减少,差异有统计学意义(P<0.05);RA活动期患者外周血Tregs细胞表面趋化因子受体CCR4、CCR6表达水平与对照组的差异有统计学意义(P<0.05);RA活动期患者外周血Tregs细胞CCR4、CCR6表达水平与DAS28评分呈正相关(P<0.05)。结论 RA患者外周血中Tregs细胞上趋化因子受体CCR4、CCR6表达增加,可能是Tregs细胞获得定向迁徙至病变关节能力的表现,也是机体炎症反应时反馈性调节的一种现象。

Objective To explore the role of CCR4 andCCR6 abnormal expression on Tregs in RA and the mechanism that may be involved. Methods Peripheral blood mononuclear cel s (PBMC) were isolated from blood in RA patients. Im-munofluorescence staining and flow cytometry assay were used to detect the expression of CCR4, CCR6 on Tregs surface. The correlation analysis between expression level of CCR4 and CCR6 on Tregs and the clinical activity parameters was performed. Results The expression of Tregs in peripheral blood of RA patients was lower than healthy control(P<0.05). The expression levels of chemokine receptor of CCR4, CCR6 on Tregs cell in peripheral blood of RA patients in active phase were higher than healthy control(P<0.05).The expression levels of chemokine receptor CCR4, CCR6 on Tregs cel in RA patients who were in active phase was positively correlated with the level of the DAS28 score (P<0.05).Conclusion The increased expression of CCR4, CCR6 on Tregs surface in rheumatoid arthritis patients not only means Tregs cell obtain the capability to directional migrate to joint, but also represents feedback regulation in the body's inflammatory response.
