摘要:

程序性死亡蛋白(PD-1)及其程序性死亡蛋白配体(PD-L1)是重要的共抑制分子,调节性T细胞(Treg)是重要的抑制性细胞,二者在肿瘤微环境中数量均增加,与肿瘤免疫逃逸及肿瘤发生发展密切相关。PD-L1对Treg的发育及功能有重要影响,抗PD-1/PD-L1抗体的应用可影响Treg的增殖和功能,进而介导耐药及超进展性疾病的发生。深入了解PD-L1与Treg在肿瘤免疫及免疫治疗中的作用及相关性,可为提高抗PD-1/PD-L1抗体疗效提供新的思路。

Abstract:

Programmed death-1 (PD-1) and programmed death ligand-1 (PD-L1) are important co-inhibitory molecules, while regulatory T cells (Tregs) are important suppressor cells. The increase of them in tumor microenvironment is closely related to tumor immune escape and tumor development. PD-L1 plays an important role in the development and function of Tregs. The application of PD-1/PD-L1 blockade also affects the proliferation and function of Tregs, which further participates in the occurrence of drug resistance and hyperprogressive disease. Further understanding of the role and correlation of PD-L1 and Tregs in tumor immunity and immunotherapy can provide new ideas for improving the efficacy of PD-1/PD-L1 blockade.
