Bile acid 7α-dehydroxylating bacteria accelerate injury-induced mucosal healing in the colon.

ABSTRACT: Host-microbiome communication is frequently perturbed in gut pathologies due to microbiome dysbiosis, leading to altered production of bacterial metabolites. Among these, 7α-dehydroxylated bile acids are notably diminished in inflammatory bowel disease patients. Herein, we investigated whether restoration of 7α-dehydroxylated bile acids levels by Clostridium scindens, a human-derived 7α-dehydroxylating bacterium, can reestablish intestinal epithelium homeostasis following colon injury. Gnotobiotic and conventional mice were subjected to chemically-induced experimental colitis following administration of Clostridium scindens. Colonization enhanced the production of 7α-dehydroxylated bile acids and conferred prophylactic and therapeutic protection against colon injury through epithelial rege
