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...

While microbial metabolites are known to influence host physiology, this study provides a glimpse into the mechanisms of our co-evolution and symbiosis. This new group of bile acid conjugates may help reduce cholesterol levels, with implications for liver disease. Full article: rdcu.be/d5VUz

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.

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
