Gastrin is an endogenous peptide hormone that acts as an agonist at the cholestocystokinin 2 (CCK2) receptor, exhibiting anorexigenic and gastrointestinal motility modulating activities. Gastrin inhibits food intake and slows gastric emptying, constricting the pyloric sphincter in vivo. Additionally, gastrin increases release of histamine and induces membrane translocation of the H+/K+ ATPase, stimulating gastric acid release.
