Introduction of HTR2B
5-hydroxytryptamine receptor 2B (5-HT2B), alternatively called serotonin receptor 2B, is a member of the 5-HT2 receptor for the neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). 5-HT2B is encoded by HTR2B gene in human. It has been found in the stomach fundus, intestine, kidney, heart, and lung, as well as in the brain, specifically in the cerebellum, cerebral cortex, amygdala, substantia nigra, caudate, thalamus, hypothalamus, and retina. HTR2B is also expressed in a number of blood vessels.

Function of HTR2B Membrane Protein
HTR2B or 5-HT2B is a beta-arrestin family member which inhibits signaling by G proteins and mediates activation of alternative signaling pathways. Similar to other 5-HT receptors, the binding of 5-HT2B and its receptor leads to a conformation change that triggers signaling through guanine nucleotide-binding proteins (G proteins) and regulates the activity of downstream effectors. 5-HT2B is involved in the regulation of dopamine and 5-hydroxytryptamine release, 5-hydroxytryptamine uptake and in the regulation of extracellular dopamine and 5-hydroxytryptamine levels, and thus affects neural activity. Furthermore, 5-HT2B has an impact on the regulation of behavior, including impulsive behavior. It is required for normal proliferation of embryonic cardiac myocytes and normal heart development. And it also contributes to protecting cardiomyocytes against apoptosis. In addition, 5-HT2B also plays a role in the adaptation of pulmonary arteries to chronic hypoxia as well as in vasoconstriction. Given the vasodilatory role of the 5-HT2B receptor, recently developed 5-HT2B receptor antagonists may be indicated for the treatment of migraine.

Application of HTR2B Membrane Protein in Literature
The results showed that astroglial 5-HT2B receptors were linked to mood disorders and may represent a novel target for cell- and molecule-specific therapies of depression and mood disorders.
The observations of this study indicated that the 5-HT2B receptor acted as a direct positive modulator of serotonin Pet1-positive neurons in an opposite way as the known 5-HT1A-negative autoreceptor.
This article focused on the subset-specific expression and immunomodulatory function of 5-HT2B in human moDCs. The results expanded the biological role of 5-HT2B which may act not only as a neurotransmitter receptor, but also as an important modulator of both innate and adaptive immune responses.
The findings of this study concluded that the 5-HT2B and 5-HT2C receptor subtypes appeared to be the predominant serotonin receptors that mediated the contractile action of this amine in bovine isolated ciliary muscles.
Authors of this study suggested that 5-HT promoted CCN2 production through the 5-HT2AR in growth plates and that it repressesed CCN2 production through the 5-HT2BR in articular cartilage for harmonized development of long bones.
