247-“冷”肿瘤转“热”:机制与治疗策略

20 Nov 2025

Description

该文章主要讨论了“冷肿瘤”(“cold” tumors)的内在机制及其转化为“热肿瘤”(“hot” tumors)的治疗策略。文章详细阐述了“冷肿瘤”逃避免疫系统检测和破坏的三大核心机制:伪装(Camouflage),即通过缺陷的抗原呈递和免疫细胞浸润障碍实现;胁迫(Coercion),即通过免疫抑制细胞网络和代谢重编程等方式压制免疫功能;以及细胞保护(Cytoprotection),即通过抵抗炎性细胞死亡信号来实现免疫逃逸。最后,文章综述了将“冷肿瘤”转化为“热肿瘤”的创新疗法,包括生物材料递送系统、靶向代谢和神经-免疫轴的策略,以及促进炎性细胞死亡的方法,旨在增强癌症免疫治疗的有效性。References: Liu Y T, Wang Y L, Wang S, et al.
