Core Tip
Core Tip: This study comprehensively investigated the changes in gut microbiota and fecal bile acid profiles and analyzed the relationship of bile acids with gut microbiota and inflammation in patients with ulcerative colitis. It was demonstrated that fecal bile acid profiles are closely related to gut microbiota and serum inflammatory cytokines. Dysregulation of gut microbiota and altered constitution of fecal bile acids may participate in regulating inflammatory responses via the bile acid receptors Takeda G-protein-coupled receptor 5 and vitamin D receptor.
