1431-肿瘤内微生物群对固体瘤免疫疗法的重塑与影响

from 聊聊Sci

这篇文章综述了瘤内微生物群在重塑肿瘤微环境(TME)以及影响实体瘤免疫治疗效果中的关键作用。研究表明,不同类型的癌症具有独特的微生物特征,这些微生物能够通过代谢产物和免疫信号通路(如 STING 和 TLR)双向调节免疫细胞的活性。虽然特定的细菌或真菌可能诱发治疗耐药,但经过基因工程改造的菌株也展现出增强肿瘤清除率和作为药物递送平台的潜力。尽管临床转化仍面临个体差异和复杂机制等挑战,但靶向瘤内微生物已成为提高免疫检查点抑制剂疗效及预测患者预后的重要研究方向。该综述系统阐述了微生物与宿主免疫之间复杂的互作网络,为开发新型联合治疗策略提供了理论基础。References:Jia J, Gao W, Wang C, et al.
