摘要 目的分析强直性脊柱炎(AS)患者外周血CD4+CD25-效应性T细胞(Teff)和CD4+CD25+Foxp3+调节性T细胞(Treg)的比例以及两群细胞表面程序性死亡蛋白配体1(PD-L1)的表达情况。方法流式细胞术检测49例AS患者和31例健康对照者外周血中Teff和Treg的比例以及PD-L1在这两种细胞表面的表达水平。结果与健康对照组相比,活动期AS患者外周血中Teff的比例显著增加,Treg比例无明显变化;活动期AS患者外周血PD-L1+Teff的比例显著降低,且低于稳定期AS患者;活动期AS患者外周血Teff膜表面PD-L1的相对表达量也显著低于稳定期AS患者和健康对照组;AS患者外周血PD-L1+Treg的比例和Treg膜表面PD-L1的相对水平均显著低于健康对照组。结论活动期AS患者外周血中Teff比例增加,PD-L1水平降低。
