摘要 目的:观察重型再生障碍性贫血(severe aplastic anenia,SAA)患者调节性T细胞(Treg细胞)、Th17及Treg/Th17比值的变化,以探讨其在SAA发病中的作用及其机制。方法:用流式细胞仪测定29例SAA患者外周血CD4+CD25highFoxp3+T细胞(Treg细胞)、CD3+CD8-IL-17A+(Th17)及比值的变化并与15名正常对照者相比较。结果:SAA患者Treg细胞(2.15±0.26)%较正常对照(5.61±0.32)%降低,差异具有统计学意义(P<0.01)。Th17比率(1.96±0.25)%较正常对照(0.91±0.12)%升高,差异具有统计学意义(P<0.01)。Treg/Th17比值(2.88±0.78)较正常对照(6.95±0.75)降低(P<0.01),Treg细胞比率和Th17细胞比率呈负相关(r=-0.7229,P<0.01),差异具有统计学意义。结论:SAA患者Treg细胞比例减低和Th17细胞比例的增加所致的Treg/Th17细胞失衡,在SAA的免疫机制中起着重要作用。
