Mucosal immunology research continues its fascination with microbial metabolites. In 2019, researchers uncovered extended functions for microbial metabolites in immunity, deepening our understanding of the regulation and function of metabolite-reactive immune cells, and revealed the receptors by which immune cells can recognize bioactive microbial metabolites. In the past year, researchers have gained a deeper understanding of the interactions between immune cells and microbially derived metabolites. Wendy Garrett describes the new insights into the receptors, immune cells and pathways triggered by microbial metabolites.

对微生物代谢产物的免疫识别。

粘膜免疫学研究继续对微生物代谢产物着迷。在2019年，研究人员发现了微生物代谢物在免疫中的扩展功能，加深了我们对代谢物反应性免疫细胞的调节和功能的了解，并揭示了免疫细胞可以识别生物活性微生物代谢物的受体。在过去的一年中，研究人员对免疫细胞和微生物衍生的代谢物之间的相互作用有了更深入的了解。温迪·加勒特（Wendy Garrett）介绍了由微生物代谢物触发的受体，免疫细胞和途径的新见解。
