Keyword:  贫血再生障碍性三联免疫治疗调节性T细胞;
Abstract: 目的 探讨三联免疫治疗再生障碍性贫血患者调节性T细胞(Treg)的变化以及其在再生障碍性贫血发病机制中的作用.方法 采用流式细胞仪分别检测21例慢性再生障碍性贫血(CAA)患者(CAA组)、9例急性再生障碍性贫血(AAA)患者(AAA组)、20例健康儿童(对照组)外周血CD4+、CD4+CD25+、CD4+CD25+CD127lowTreg水平.结果 CAA组和AAA组患者治疗前外周血CD4+、CD4+CD25+、CD4+ CD2+ CD127lowTreg水平分别为0.304±0.018、0.052±0.004、0.048±0.021和0.259±0.041、0.034±0.002、0.021±0.008,治疗后分别为0.321±0.009、0.062±0.006、0.055±0.011和0.323±0.029、0.065±0.009、0.041±0.009,均低于对照组的0.369±0.032、0.070±0.005、0.058±0.015,差异有统计学意义(P< 0.05);CAA组和AAA组患者治疗后外周血CD4+、CD;CD25+、CD4+CD25+CD127lowTreg水平均较治疗前明显上升(P<0.05).结论 三联免疫治疗可能是通过调节Treg细胞功能治疗再生障碍性贫血.
