1221-NF2缺失介导免疫治疗耐药及恢复策略研究

from 聊聊Sci

这份研究论文探讨了肿瘤抑制因子 NF2 缺失导致实体瘤产生免疫治疗耐药性的具体生物学机制。研究发现,NF2 功能丧失会通过重塑肿瘤免疫微环境,诱导免疫抑制性巨噬细胞的大量聚集,从而使肿瘤对 CAR T 细胞及 PD-1 抑制剂产生抵抗。这种耐药现象具有部位特异性,且与希波(Hippo)信号通路的异常激活密切相关。实验证明,通过药理学手段抑制 TEAD 蛋白或针对性靶向这些抑制性骨髓细胞,可以逆转耐药性并恢复免疫治疗的疗效。该成果为治疗 NF2 缺陷型间皮瘤等恶性肿瘤提供了新的联合用药策略。References:Lopez-Lago M A, Taleb M, Ningoo M, et al.
