摘要 目的:探讨系统性红斑狼疮(SLE)患者外周血辅助性T细胞17(T help cell 17,Th17)的水平和意义。方法:分离、刺激培养人外周血单个核细胞后,利用流式细胞术(FCM)分析SLE患者和正常人外周血中Th17细胞占CD+4T的比例,定量PCR检测外周血单个核细胞RORγt的表达水平、酶联免疫吸附法(ELISA)检测外周血IL-17的水平。结果:静止期和活动期SLE患者外周血中Th17细胞比例与正常对照组相比较差异有统计学意义(P<0.05),且活动期SLE患者与静止期患者相比差异有统计学意义(P<0.05)。SLE患者活动期组外周血单个核细胞RORγt mRNA表达水平与健康组及静止期组相比差异有统计学意义(P<0.05),静止期组和健康组相比差异无统计学意义(P>0.05)。与正常对照组相比,静止期和活动期SLE患者血清IL-17的水平有显著升高(P<0.05),且与静止期患者相比,活动期SLE患者差异有统计学意义(P<0.05)。结论:Th17细胞可能通过分泌细胞因子IL-17参与了SLE发病及病情发展。
