Abstract
Inflammatory bowel diseases (IBDs) are chronic inflammatory multifactorial diseases caused by genetic, immune, and environmental factors. A decrease in intestinal serotonin transporter (SERT), which controls the extracellular availability of serotonin (5-HT) has been implicated in IBD. We previously showed that SERT deletion in mice altered gut bacterial community structure. The gut microbiota-derived metabolites are functional intermediaries between the microbiota and host. Here, we investigated the impact of SERT deficiency on gut metabolites under basal conditions and chronic colitis mimicking human IBD.
