5-HT3 Receptors

The 5-HT3 receptor is expressed throughout the central and peripheral nervous systems and mediates a variety of physiological functions. On a cellular level, it has been shown that postsynaptic 5-HT3 receptors mediate fast excitatory synaptic transmission in rat neocortical interneurons, amygdala, and … Visa mer The 5-HT3 receptor belongs to the Cys-loop superfamily of ligand-gated ion channels (LGICs) and therefore differs structurally and functionally from all other 5-HT receptors (5-hydroxytryptamine, or serotonin receptors) … Visa mer The genes encoding human 5-HT3 receptors are located on chromosomes 11 (HTR3A, HTR3B) and 3 (HTR3C, HTR3D, HTR3E), so it appears that they have arisen from gene duplications. The genes HTR3A and HTR3B encode the 5-HT3A and 5-HT3B subunits and Visa mer Agonists for the receptor include: • Cereulide • 2-methyl-5-HT • Alpha-Methyltryptamine Visa mer These agents are not agonists at the receptor, but increase the affinity or efficacy of the receptors for an agonist: • Indole Derivatives • Small Organic Anaesthetics Visa mer The 5-HT3 receptor differs markedly in structure and mechanism from the other 5-HT receptor subtypes, which are all G-protein-coupled. A functional channel may be composed of five identical 5-HT3A subunits (homopentameric) or a mixture of 5-HT3A and one of … Visa mer When the receptor is activated to open the ion channel by agonists, the following effects are observed: • CNS: nausea and vomiting center in brain stem, … Visa mer Antagonists for the receptor (sorted by their respective therapeutic application) include: • Visa mer Webb5-HT3A receptors select among permeant ions based on size and charge. The membrane-associated (MA) helix lines the portals into the channel's cytoplasmic vestibule in the 4-Å resolution structure of the homologous acetylcholine receptor. 5-HT3A MA helix residues are important determinants of single-channel conductance. pop fashionsWebb26 jan. 2016 · The 5-HT3 receptor emerged as a likely mediator of the antiemetic effect, and the pharmaceutical industry employed various strategies to develop selective 5-HT3 receptor antagonists.
