Ursodeoxycholic Acid (UDCA) Mitigates the Host Inflammatory Response during Clostridioides difficile Infection by Altering Gut Bile Acids
INFECTION AND IMMUNITY, 88(6).
author keywords: C. difficile; FXR; UDCA; bile acids; inflammation; microbiome; ursodiol
MeSH headings : Animals; Bile Acids and Salts / metabolism; Biomarkers; Clostridioides difficile / drug effects; Clostridium Infections / drug therapy; Clostridium Infections / genetics; Clostridium Infections / metabolism; Clostridium Infections / microbiology; Computational Biology / methods; Dose-Response Relationship, Drug; Fibroblast Growth Factors / metabolism; Fragile X Mental Retardation Protein / metabolism; Gastrointestinal Microbiome / drug effects; Gene Expression Profiling; Host-Pathogen Interactions / drug effects; Host-Pathogen Interactions / genetics; Humans; Life Cycle Stages; Mice; Signal Transduction; Transcriptome; Ursodeoxycholic Acid / pharmacology; Ursodeoxycholic Acid / physiology
TL;DR:
Although ursodiol pretreatment did not result in a consistent decrease in the C. difficile life cycle in vivo, it was able to attenuate an overly robust inflammatory response that is detrimental to the host during CDI.
