Cancer immunotherapy is increasingly popular in the field of cancer treatment, and related research is emerging. For patients with non-small cell lung cancer (NSCLC), in recent years, immune checkpoint inhibitors (ICIs) represented by programmed cell death 1 (PD-1)/programmed cell death ligand 1 (PD-L1) immunosuppressants, have become one of the most promising treatments for malignant tumors. Immune checkpoint blockade therapy includes anti-cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) mAb, anti-PD-1 mAb and anti-PD-L1 mAb, with the best-known number of PD-L1 immunotherapy. At present, ICIs have achieved very good therapeutic results in clinical treatment, but with less effective efficiency, so we hope to obtain higher therapeutic efficiency. In recent years, exosomal PD-L1 has played an important role in the progress of immunotherapy for NSCLC. This paper reviews the effects of tumor exosomal PD-L1 protein on the tumor microenvironment, the effect prediction of immunotherapy, and as novel therapeutic strategies for immunotherapy in NSCLC. .
【中文题目：外泌体PD-L1在非小细胞肺癌免疫治疗 的研究进展】 【中文摘要：肿瘤免疫疗法在当前癌症治疗领域中愈来愈受瞩目，相关研究也层出不穷。对于非小细胞肺癌（non-small cell lung cancer, NSCLC）患者来说，近些年来，以程序性死亡受体1（programmed cell death 1, PD-1）/程序性死亡配体1（programmed cell death ligand 1, PD-L1）免疫抑制剂为代表的免疫检查点抑制剂（immune checkpoint inhibitors, ICIs）已经成为治疗恶性肿瘤的一种最具前景的治疗方案。免疫检查点阻断治疗包括抗细胞毒T淋巴细胞相关抗原4（cytotoxic T lymphocyte-associated antigen 4, CTLA-4）单抗、抗PD-1单抗和抗PD-L1单抗，其中最被人熟知的为PD-L1免疫疗法。目前ICIs在临床治疗中取得了很不错的治疗效果，但有效率较低，因此我们希望获得更高的治疗有效率。近几年外泌体PD-L1在NSCLC免疫治疗中发挥了重要作用。本文就肿瘤外泌体PD-L1蛋白对肿瘤微环境的影响、预测免疫治疗效果以及作为NSCLC免疫治疗的新型治疗策略作一综述。 】 【中文关键词：外泌体；PD-L1；肺肿瘤；免疫治疗】.
