- W251499933 abstract "目的探讨乙型肝炎病毒所致慢加急性肝衰竭(HBV—ACLF)患者外周血中CD8^+T细胞上PD-1(Programmed death-1)的表达以及对CD8^+T细胞的影响。方法收集60例HBV—ACLF患者外周血;应用流式细胞仪检测外周血中CD8^+淋巴细胞上的PD-1、CD95、穿孔素、颗粒酶A、颗粒酶B、CD107a的表达以及CD14细胞上PD—L1的表达;根据不同病情分期和不同预后比较各分子的表达差异;设15名肝硬化患者及15名健康人为对照组。结果(1)HBV-ACLF患者CD8^+T细胞上PD-1较肝硬化组和健康组表达上调(P〈0.05);好转组PD-1表达率低于无效组(P〈0.05);早、中、晚三期PD-1表达率呈上升趋势(P〈0.05);(2)PD—L1在好转组及病情早期表达相对最低;(3)PD-1与CD95在死亡组表达明显升高;穿孔素、颗粒酶及CD107a在死亡组表达升高,但PD-1在这三类细胞上表达率非常低。结论PD-1在HBV.ACLF患者外周血CD8^+T细胞上表达上调,且与病情严重程度呈正比。其上调表达可能促进总CD8^+T细胞的凋亡,但对于具有杀伤活性的CD8^+T细胞抑制作用相对较弱。" @default.
