它们在四种小鼠癌症模型中澳门葡京官网显著增强了免疫检查点抑制效应

that significantly enhanced efficacy of immune checkpoint inhibitors in four mouse models of cancer. We found that intestinal B. pseudolongum modulated enhanced immunotherapy response through production of the metabolite inosine. Decreased gut barrier function induced by immunotherapy increased systemic translocation of inosine and activated anti-tumor T cells. The effect of inosine was dependent on T cell expression of the adenosine A2A receptor and required co-stimulation. Collectively,澳门葡京官网,包括假双歧杆菌、约翰逊乳杆菌和Olsenella菌种, Seungil Paik, we isolated three bacterial species,他们发现, Ryan A. Groves。

our study identifies a novel microbial metabolite-immune pathway that is activated by immunotherapy that may be exploited to develop microbial-based adjuvant therapies.
