The 5-HT 2 receptors are a subfamily of 5-HT receptors that bind the endogenous neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). [1] The 5-HT 2 subfamily consists of three G protein-coupled receptors (GPCRs) which are coupled to G q /G 11 and mediate excitatory neurotransmission , [ 2 ] including 5-HT 2A , 5-HT 2B , and 5-HT 2C .
The 5-HT 2A receptor is a subtype of the 5-HT 2 receptor that belongs to the serotonin receptor family and is a G protein-coupled receptor (GPCR). [4] The 5-HT 2A receptor is a cell surface receptor, [5] but has several intracellular locations. [6] Like all 5-HT 2 receptors, the 5-HT 2A receptor is G q /G 11-protein coupled.
5-HT receptors, 5-hydroxytryptamine receptors, or serotonin receptors, are a group of G protein-coupled receptor and ligand-gated ion channels found in the central and peripheral nervous systems. [ 1 ] [ 2 ] [ 3 ] They mediate both excitatory and inhibitory neurotransmission .
The 5-HT 2C receptor is a subtype of the 5-HT2 receptor that binds the endogenous neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). Like all 5-HT2 receptors, it is a G protein-coupled receptor (GPCR) that is coupled to G q /G 11 and mediates excitatory neurotransmission .
The 5-HT 2 receptors (of which the 5-HT 2B receptor is a subtype) mediate many of the central and peripheral physiologic functions of serotonin. Cardiovascular effects include contraction of blood vessels and shape changes in platelets; central nervous system (CNS) effects include neuronal sensitization to tactile stimuli and mediation of some ...
Studies indicate that 5-HT 2C receptor activation will regulate appetite and food consumption, most likely by promoting satiety through appetite suppression by activation of 5-HT 2C. Consequently, selective agents with high affinity for this receptor over 5-HT 2B and 5-HT2 2A are being developed for the treatment of obesity. [38] [6]
