Potentiation of serotonin signaling leads to increased carbohydrate and lipid absorption in the murine small intestine

Study demonstrates that enhanced serotonin signaling in SERT-deficient mice increases both carbohydrate and lipid absorption in the small intestine through serotonin-mediated mucosal growth. Findings suggest serotonin's role as a mucosal growth factor directly impacts nutrient absorption capacity.
