1588-粪便微生物移植与免疫检查点抑制剂治疗中的免疫调控

from 聊聊Sci

本综述探讨了粪便微生物移植(FMT)在提升免疫检查点抑制剂(ICI)治疗癌症效果及减轻其副作用方面的关键作用。研究提出了一个两阶段生态功能模型,强调了清除受体原有的有害菌群以及实现供体菌群功能稳定性的重要性。作者分析指出,短链脂肪酸(SCFA)的产生和特定代谢通路是维持免疫平衡、预防严重毒性反应的核心机制。文中特别提到,普氏栖粪杆菌等有益菌能增强治疗耐受性,而塞加特氏共栖杆菌在特定免疫背景下可能诱发炎症风险。通过对黑色素瘤、肾细胞癌和非小细胞肺癌临床试验的整合,本文为未来通过功能导向筛选供体和动态监测微生物群落来实现精准肿瘤治疗提供了理论支撑。References:Ninkov M, Maleki Vareki S.
