Research in mice shows how diet alters immune system function through a gut microbe

Research in mice demonstrates how diet alters a gut microbe molecule that, in turn, prompts immune cells to downregulate inflammation. The study elucidates molecular mechanism behind long-standing belief that diet, microbiota, and immunity influence one another in myriad ways. If affirmed in larger animals and humans, the findings could inform the design of small-molecule drugs that regulate immune response to treat inflammatory conditions
