5-Hydroxytryptamine receptor 3B (5-HT3B, HTR3B) belongs to the superfamily of ligand-gated ion channels. Serotonin receptors, other than the 5-HT3 subtype, belong to the superfamily of G-protein coupled receptors.The 5-HT3 receptor is formed by five subunits arranged around a pore forming unit. Receptors could be either monomeric, such as 5-HT3A or heteromeric entities like 5-HT3A/B. Indeed, the type of channel formed displays different pharmacological and electrophysiological characteristics1, 2. To date, five 5-HT3 subunits have been identified and labeled 5-HT3A-E, which show variability in the N-terminus and in the transmembrane region2. 5-HT3A and 5-HT3B are the best characterized among the different types.In general, 5-HT3 receptors are located in the peripheral and central nervous system, in lymphocytes and intestinal enterochromaffine cells2. In presynaptic neurons, activation of these receptors leads to an increase in intracellular Ca2+ (by both influx and mobilization of intracellular stores), and modulates the release of a number of neurotransmitters and neuropeptides2. At the postsynaptic level, activation leads to membrane depolarization2, 3. The localization of 5-HT3B subunits is somewhat controversial; some studies show that its expression is restricted to the peripheral nervous system and others show that it is also detected in the brain and in hippocampal neurons1, 4-7.5-HT3 receptors have become important targets for which to develop treatments for irritable bowel syndrome (IBS), side effects resulting from chemotherapeutic treatment, schizophrenia and bipolar disorder1, 2.
