摘要:

肿瘤细胞表达程序性死亡蛋白配体-1(PD-L1)是引起免疫逃逸的主要机制,也是免疫检查点抑制剂治疗疗效的预测因素。PD-L1表达受多种机制调控,其中DNA甲基化、组蛋白修饰、非编码RNA等表观遗传修饰可通过调控PD-L1的表达促进肿瘤发生发展和产生耐药。明确其调控机制可为肿瘤临床免疫治疗带来新的思路。

Abstract:

Tumor cells expression of programmed death ligand-1 (PD-L1) is a major mechanism of immune escape and a predictor of therapeutic efficacy of immune checkpoint inhibitors. The expression of PD-L1 is regulated by a variety of mechanisms, among which epigenetic modifications such as DNA methylation, histone modification and non-coding RNA can promote the occurrence, development and drug resistance of tumors by regulating the expression of PD-L1. To clarify its regulation mechanism can bring new ideas for clinical immunotherapy of tumors.
