1112-肠道微生物群与癌症免疫检查点阻断治疗

from 聊聊Sci

这份综述深入探讨了肠道微生物群、代谢产物以及饮食如何共同调节癌症免疫检查点阻断(ICB)疗法的效果。研究表明,肠道菌群的多样性和特定菌种是决定治疗成败的关键因素,而抗生素或某些益生菌的使用可能会削弱疗效。微生物通过代谢产物循环、抗原交叉反应以及诱导微生物易位等多种机制,从远端增强宿主的抗肿瘤免疫反应。此外,文章强调了高纤维饮食通常能通过产生短链脂肪酸提升药效,而高脂肪饮食与肥胖对治疗的影响则更为复杂且存在争议。作者还分析了肠道菌群与免疫相关副作用(irAEs)之间的关联,指出特定的微生物组成可以预测不良反应的发生。最后,该文献指出了目前在肠道免疫细胞运输及“暗代谢组”研究中的知识空白,为未来通过精准调节肠道环境来优化癌症免疫治疗指明了方向。References:Gladstone J, Sonnenberg G.
