5-HT2A Serotonin Receptor: A serotonin receptor subtype found widely distributed in peripheral tissues where it mediates the contractile responses of variety of tissues that contain SMOOTH MUSCLE. Selective 5-HT2A receptor antagonists include KETANSERIN. The 5-HT2A subtype is also located in BASAL GANGLIA and CEREBRAL CORTEX of the BRAIN where it mediates the effects of HALLUCINOGENS such as LSD.
The explanation for therapeutic effects characteristic of SSRIs may be found in delayed neurochemical adaptations. A leading hypothesis for this action is desensitization of somatodendritic serotonin 1A autoreceptors in the midbrain raphe. The hypothesis to explain why SSRIs have such diverse therapeutic actions is that somatodendritic 5HT1A autoreceptor desensitization increases serotonin in those critical brain regions and at those key serotonin receptor subtype(s) which may mediate the pathophysiologies of the various disorders. Understanding the topography of serotonin receptor subtypes in discrete anatomical pathways may enhance our understanding of both the therapeutic actions and side effects of these important pharmaceutical agents.

Prior to investigating the effect of GS on mouse serotonin receptor 2a (mHtr2a), it was first examined whether the cloned mHtr2a was functionally active in transiently-expressed HEK-293T cells. For this reason, HEK293T cells expressing mHtr2a were treated with α-Me-5HT, an agonist for serotonin receptor 2 subfamily, and its response was measured by calcium imaging. It turned out, as shown in Fig. 1A, that treatment of 10 μM α-Me-5HT significantly increased the intracellular fluorescence intensity, which is proportional to the intracellular calcium concentration. As expected, the increment by α-Me-5HT was not observed in cells that were only transfected with the vector pcDNA3.1 alone (data not shown). Moreover, the response to α-Me-5HT was virtually abolished by pretreatment of 500 nM ketanserin, a specific antagonist for serotonin receptor 2a ("+Ket" in Fig. 1A). These data suggest that the cloned mHtr2a was indeed functionally active in HEK293T cells, and thus considered ready to be used ...
5-hydroxytryptamine receptors or 5-HT 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. They mediate both excitatory and inhibitory neurotransmission. The serotonin receptors are activated by the neurotransmitter serotonin, which acts as their natural ligand. The serotonin receptors modulate the release of many neurotransmitters, including glutamate, GABA, dopamine, epinephrine / norepinephrine, and acetylcholine, as well as many hormones, including oxytocin, prolactin, vasopressin, cortisol, corticotropin, and substance P, among others. The serotonin receptors influence various biological and neurological processes such as aggression, anxiety, appetite, cognition, learning, memory, mood, nausea, sleep, and thermoregulation. The serotonin receptors are the target of a variety of pharmaceutical drugs, including many antidepressants, antipsychotics, anorectics, antiemetics, ...

The present study is the first thorough analysis of serotonin receptor subtype expression in TRCs. An initial screening using RT-PCR with 14 5-HT receptor subtype-specific primers demonstrated the presence of 5-HT1A and 5-HT3 receptor mRNAs in pure taste bud total RNA. Additionally, data suggest the expression of 5-HT1B, 5-HT1D, 5-HT1E, 5-HT1F, 5-HT2A, 5-HT2B, 5-HT2C, 5-HT4, 5-HT5A, 5-HT5B, 5-HT6, and 5-HT7, in rat posterior TRCs to be unlikely. Because these primers were first optimized on rat positive control tissue, even low-level expression of these subtypes in rat taste buds would likely have been detected. However, if some tissue-specific postgenomic modification, such as alternative splicing, exists in TRCs, detection of these mRNAs might not have been evident with these primer sets. Moreover, our 14 primer sets comprise a minority of all serotonin receptor subtypes, whose exhaustive exploration would be a prohibitively large undertaking. Also, it is always possible that rare expression ...

Two distinct serotonin (5-hydroxytryptamine) receptors designated serotonin 1 and serotonin 2 bind tritium-labeled serotonin and tritium-labeled spiroperidol, respectively. Drug potencies at serotonin 2 sites, but not at serotonin 1 sites, predict their effects on the "serotonin behavioral syndrome," indicating that serotonin 2 sites mediate these behaviors. The limited correlation of drug effects with regulation by guanine nucleotides suggests that serotonin 1 sites might be linked to adenylate cyclase. Drug specificities of serotonin-elicited synaptic inhibition and excitation may reflect serotonin 1 and serotonin 2 receptor interactions, respectively. ...
Background: The main source of 5-HT in body is in enterchromafin cells of intestine, different studies mentioned different roles for endogenous 5-HT and receptors involved and it is not clearified the mechanism of action of endogenous 5-HT.. Objectives: To study the role of endogenous 5-HT on modulation of contraction and relaxation responses induced by electrical field stimulation (EFS) in different regions of the rat intestine..

TY - JOUR. T1 - Pharmacological properties of serotonin receptor subtypes mediating contraction of bovine inferior alveolar arteries. AU - ODonohue, H. A.. AU - Abel, P. W.. AU - Bockman, C. S.. PY - 2004/3. Y1 - 2004/3. N2 - Objective: To characterise the 5-hydroxytryptamine (5-HT) receptor subtypes mediating contraction of the inferior alveolar artery. Additionally, to determine the role of cyclooxygenase products, nitric oxide, endothelium, monoamine oxidase and 5-HT uptake in modulating contraction of inferior alveolar arteries to 5-HT. Methods: Contractile responses to 5-HT were examined in vitro using ring segments of bovine inferior alveolar arteries. Affinity constants (KBs) of subtype-selective 5-HT receptor antagonists were determined to characterise the 5-HT receptor-subtypes causing contraction of inferior alveolar arteries. Results: In 100nM ketanserin or 30nM spiperone, 5-HT caused a biphasic contraction best-fit by a two-site curve model, where one site was antagonist-sensitive ...
Treatment with specific antidepressant and antipsychotic medications is often guided empirically. Despite the wide array of drugs available for treatment, some patients do not initially respond to treatment and others who respond early may eventually relapse or develop serious side effects. Antidepressant selection may be more effectively guided by genotyping polymorphic genes encoding several cytochrome P450 enzymes, the serotonin transporter, and the serotonin (5-hydroxytryptamine) receptors HTR2A and HTR2C.(1). Drugs that bind to the serotonin receptors have a wide range of effects including altering the activation of the receptors, rendering them more or less sensitive to drug concentration, or blocking the receptor. Variations (polymorphisms) in the genes that encode for the serotonin receptor have been associated with different types of drug responses including:. -Allelic variation in the HTR2A gene has been reported to affect response to the selective serotonin reuptake inhibitor (SSRI) ...
JC virus (JCV) is a common human polyomavirus responsible for the fatal demyelinating disease progressive multifocal leukoencephalopathy (PML), in immunocompromised individuals. About 5% of AIDS patients develop this currently untreatable fatal disease. Typical and atypical antipsychotic drugs inhibit JCV infection of glial cells. Elphick et al. now find that the cellular receptor for JCV on glial cells is a serotonin receptor. The findings contribute to the understanding of the pathogenesis of PML in AIDS patients and suggest that therapy based on existing serotonin receptor inhibitors may be feasible.. G. F. Elphick, W.

Dendritic cells (DCs) are potent antigen-presenting cells endowed with the unique ability to initiate adaptive immune responses upon inflammation. Inflammatory processes are often associated with an increased production of serotonin, which operates by activating specific receptors. However, the functional role of serotonin receptors in regulation of DC functions is poorly understood. Here we demonstrate that expression of serotonin receptor 5-HT7 (5-HT7R) as well as its down-stream effector Cdc42 is upregulated in DCs upon maturation. While DC maturation was independent of 5-HT7R, receptor stimulation affected DC morphology via Cdc42-mediated signaling. In addition, basal activity of 5-HT7R was required for the proper expression of the chemokine receptor CCR7, which is a key factor to control DC migration. Consistently, we observed that 5-HT7R enhances chemotactic motility of DCs in vitro by modulating their directionality and migration velocity. Accordingly, migration of DCs in murine colon ...

Effects of 5-hydroxytryptamine (5-HT) agonists were investigated in the bovine isolated mesenteric lymphatics, and then the 5-HT receptor subtypes in the responses were pharmacologically classified by use of several 5-HT antagonists. Addition of 5-HT and that of alpha-methyl-5-hydroxytryptamine (alpha-methyl-5-HT) both produced concentration-dependent contractions in the presence of 3 x 10(-6) M [(1 alpha H, 5 alpha H)-8-methyl-8-azabicyclo(3.2.1)oct-3 alpha-yl]1H-indole-3-carboxylate hydrochloride, whereas 5-carboxamidotryptamine (5-CT) and 2-methyl-5-hydroxytryptamine (2-methyl-5-HT) caused no, or only slight, contraction in the lymphatics. Pretreatment with ketanserin caused a significant shift to the right in the concentration-response curve for 5-HT or alpha-methyl-5-hydroxytryptamine. Schild plot analyses showed that the pA2 values for ketanserin against 5-HT and alpha-methyl-5-hydroxytryptamine were 8.75 and 8.68, respectively. In contrast, 5-CT, 5-HT and metoclopramide caused ...
This group includes drugs that interact with specific serotonin or 5-HT (5-hydroxytryptamine) receptors. Serotonin contains almost all organs and tissues, however, more than 90% found in enterochromaffin cells of the gastrointestinal tract. Blood accumulates serotonin (active transport) in platelets, in the Central nervous system in serotonergic neurons; the latter it is synthesized and released.. Pharmacological effects of serotonin are mediated by the excitation of 5-HT1, 5-HT2 and 5-HT3-type serotonin receptors. Its main effect is the contraction of smooth muscle, vasoconstriction (except of vessels in skeletal muscle and heart), increased blood pressure, activation of platelet aggregation, increased tone and peristalsis of the gastrointestinal tract, stimulation of pain and the development of nausea and vomiting. Some serotonergic agents (serotonin, Maximin, etc.) stimulate serotonin receptors and are used primarily in hemorrhagic syndrome, Hypo - and aplastic anemia, hemorrhagic vasculitis, ...
