Metoclopramide stimulates catecholamine- and granin-derived peptide secretion from pheochromocytoma cells through activation of serotonin type 4 (5-HT4) receptors. Metoclopramide and the 5-HT(4) receptor agonist cisapride were found to activate catecholamine- and granin-derived peptide secretions by cultured tumor cells.

Pharmacology review. This gene is a member of the family of human serotonin receptors, which are G protein-coupled receptors that stimulate cAMP production in response to serotonin (5-hydroxytryptamine). The gene product is a glycosylated transmembrane protein that functions in both the peripheral and central nervous system to modulate the release of various neurotransmitters . Selective antagonist of this type of serotonin receptor have an impact on behaviour and seem to improve the spatiel memory of laboratory animal. 25. 5-HT7 Receptors 5-HT7 receptors are expressed abundantly in the vessels and are responsible for persistant vasodilation of anesthesized experimental animal.
