1190-炎性细胞因子诱导癌症新脆弱性

这项研究探讨了肿瘤细胞如何通过改变遗传依赖性来适应炎症细胞因子（如IFNβ、IFNγ和TNF）带来的压力。研究人员在八种癌症模型中进行了全基因组规模的CRISPR筛选，旨在识别那些能让肿瘤在炎症环境下生存的关键基因。实验发现了GPI转座酶复合物和脂质磷酸酶FITM2是特定于干扰素的生存依赖项。通过敲除这些基因，研究者成功增强了小鼠体内免疫检查点阻断（ICB）疗法的效果。特别是FITM2的缺失会诱发内质网应激和氧化应激，最终导致癌细胞发生类副凋亡。总体而言，该研究揭示了炎症环境诱导的肿瘤内在脆弱性，为提高癌症免疫治疗效果提供了新的潜在靶点。References:* Cheruiyot CK, Kim SY, Dubrot J, Lane-Reticker SK, Miranda A, Kammula AV, Perera JJ, Du PP, Chuong CL, Fetterman R...去小宇宙查看完整单集简介前往小宇宙评论区与主播互动
