Serotonin acts through several receptor types and subtypes. The profusion of 5-HT receptors should eventually allow a better understanding of the different and complex processes in which serotonin is involved. 2020-12-23 · Selective serotonin receptor (5-HT3) antagonists block serotonin both peripherally on vagal nerve terminals in the gastrointestinal (GI) system and centrally in the chemoreceptor trigger zone in the area postrema of the fourth ventricle, resulting in powerful antiemetic effects. Serotonin possesses both vasoconstrictor and vasodilator properties. The constrictor action of the monoamine can be due to: (a) direct activation of vascular smooth muscle; in most blood vessels, this is mediated by S2-serotonergic receptors; (b) augmentation (amplification) of the action of other e … Reduction of serotonin (5HT 1A) receptor availability ([11 C]WAY binding potential) in aging.

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.

Therefore, maximizing the receptor's functionality in serotonin-deficient disorders will optimize the function of the systems requiring this neurotransmitter .

The clinical effects of serotonin receptors are multifaceted. At this time, only a few of the identified receptors have drugs that are currently marketed for use in humans. Buspirone stimulates the 5-HT1A receptor to cause antianxiety effects.

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.

They activate serotonin receptors in a manner similar to that of serotonin (5-hydroxytryptamine; 5-HT), a neurotransmitter and hormone and the endogenous ligand of the serotonin receptors.
