摘要: 摘要: 程序性死亡蛋白 1 (PD-1) 主要表达于活化的 T 细胞表面, 其与配体 PD-L1/PD-L2 结合后激活下游信号通路负向调控 T 细胞的活化。肿瘤发生时肿瘤细胞表面 PD-1 配体的表达异常增加, 介导了肿瘤的免疫逃逸。抑制 PD-1 信号通路有助于 T 细胞的抗肿瘤效应, 该通路抑制剂的开发也成为肿瘤免疫治疗的一个热点。本文阐述了抑制 PD-1 通路在体内外实验中的抗肿瘤效应以及 PD-1 通路抑制剂临床开发的最新进展, 为肿瘤免疫治疗提供一个新的靶点, 并为免疫治疗联合传统治疗方法的临床应用提供理论及临床基础。

Abstract: Abstract: Programmed death1 (PD-1) is mainly expressed on the surface of activated T cell. The combination between PD-1 and its legends PD-L1/PD-L2 activate downstream signaling pathways and negatively regulate T cell activation. Ab⁃ normal increase expression of PD-L1 on tumor cell surface mediates the tumor immune escape. Inhibition of PD-1 signaling pathway contributes to antitumor effect of T cells. The development of this pathway inhibitors has become a hot spot for tu⁃ mor immunotherapy. This article expounds the progress about antitumor effects mediated by PD-1 pathway inhibition from experiments in vivo or in vitro and clinical development of PD-1 pathway inhibitors, providing a new target for cancer immu⁃ notherapy and theoretical and clinical basis for the clinical application of immunotherapy with traditional therapy methods.
