CD8+T细胞耗竭发生和特征及其与肿瘤免疫治疗耐药的研究进展

Research progress on the occurrence and characteristics of CD8+T cell exhaustion and its relationship with tumor immunotherapy resistance

    摘要
  • 摘要: 免疫检查点抑制剂（immune checkpoint inhibitors，ICIs）是治疗多种肿瘤的重要手段，但耐药成为其最大难题。肿瘤免疫治疗耐药与肿瘤微环境（tumor microenvironment，TME）密切相关，TME中CD8+T细胞耗竭不仅持续性高表达抑制性受体（inhibitory receptors，IRs），同时也是导致ICIs耐药的关键环节，靶向IRs为克服免疫治疗耐药提供了新思路。本文将重点对CD8+T细胞耗竭发生和特征及其与肿瘤免疫治疗耐药性相关的研究进行综述。

     

    Abstract: Immune checkpoint inhibitors (ICIs) have emerged as important targets of treatment for various types of cancers, yet drug resistance poses considerable problems. Tumor immunotherapy resistance is closely related to the tumor microenvironment (TME). Exhaustion of CD8+T cells in the TME continuously express high levels of inhibitory receptors (IRs) and play a central role in ICIs resistance. Targeting IRs provides new prospects for overcoming immunotherapy resistance. This review focuses on the occurrence and characteristics of CD8+T cell exhaustion and explores its association with tumor immunotherapy resistance.
