Illuminating microbial dark matter: Dietary alterations uncover microbial regulation of immunity and metabolism

Dietary alterations uncover microbial regulation of immunity and metabolism

science.org

In this issue of @nature.com, we identified a new class of molecules: host-modified microbial metabolites. While microbial bile acid metabolites are FXR agonists, we show that the host can modify them into antagonists, therefore balancing microbial signaling. www.nature.com/articles/s41... 1/2

Host metabolism balances microbial regulation of bile acid signalling - Nature

A family of host-derived bile acid–methylcysteamine conjugates functions as FXR antagonists, forming part of a microbiota-dependent metabolic network that regulates FXR-dependent physiology.
