摘要: 程序性死亡分子-1(PD-1)是T淋巴细胞膜表面表达的负向协同刺激分子, 与其主要配体(PD-L1)形成通路后,可以减弱T淋巴细胞的免疫反应,甚至导致T淋巴细胞功能衰竭。PD-1/PD-L1信号通路在乙型肝炎病毒感染后的效应T细胞免疫耐受中具有重要作用,阻断该途径可能是抗病毒治疗的方向之一,具有良好的应用前景。

Abstract: Programmed cell death-1(PD-1),as an inhibitory co-stimulatory molecule,is expressed on the surface of T lymphocyte membranes. After interacting with its main ligand,programmed death-1 ligand(PD-L1),PD-1 decreases immune response of T lymphocytes,and even damages the overall functioning of T lymphocytes. PD-1/PD-L1 signaling pathway plays an important role in the tolerance of T cell immune response triggered by hepatitis B virus infection. Studies indicate that blocking this pathway may provide an new insights into antiretroviral therapy,and might be a promising applications in clinical practice.
