069-免疫检查点阻断:响应、抵抗与毒性

24 Aug 2025

Description

这篇文章主要讨论了免疫检查点阻断(ICB)在癌症治疗中的应用及其局限性。文中概述了ICB的作用机制,特别是针对CTLA-4和PD-1/PD-L1等关键免疫检查点的策略。文章还详细探讨了影响ICB治疗效果和毒性(irAEs)的各种因素,包括宿主内在因素(如肿瘤遗传、肿瘤微环境中的免疫细胞和微生物)和宿主外在因素(外暴露组),例如饮食、压力、用药以及环境暴露。最后,该文献还提出了旨在提高疗效和降低副作用的诊断与治疗策略,以期拓宽ICB的适用范围并改善癌症患者的预后。References: Morad G, Helmink B A, Sharma P, et al.
