Neonatal fungi promote lifelong metabolic health through macrophage-dependent β cell development.

Loss of early-life microbial diversity is correlated with diabetes, yet mechanisms by which microbes influence disease remain elusive. We report a critical neonatal window in mice when microbiota disruption results in lifelong metabolic consequences stemming from reduced β cell development. We show evidence for the existence of a similar program in humans and identify specific fungi and bacteria that are sufficient for β cell growth.

Draft genome of a human gut-derived sp. that ameliorates colitis and colitis-associated sociability deficits in mice.

is a genus of anaerobic, gram-positive bacteria commonly found in mammalian gastrointestinal tracts. Yet, how variations among different strains can impact host health is poorly understood. We present a sp.
