Scientific background

5-HT is involved in a variety of physiological and biological processes. In the brain, 5-HT has been found to affect sleep, mood, appetite, anxiety, aggression, perception, pain, and cognition1. Signaling of 5-HT is mediated by receptors that are located on the cell membrane of neurons and most other cells in the body. The 5-HT2 family consists of three G-protein coupled receptors (GPCRs): 5-HT2A, 5-HT2B, and 5-HT2C2. Like other members, they are transmembrane proteins consisting of seven membrane-spanning α-helical segments with an extracellular N-terminus and an intracellular C-terminus. The binding of 5-HT to one of its receptors is thought to elicit a conformational change that activates associated heterotrimeric G proteins and recruits other downstream signaling/scaffolding molecules, such as GPCR kinases and β-arrestins.

5-HT2B receptors have been found to be present in both rodent and human tissues, particularly in the cardiovascular system, gastrointestinal tract, bone, and central nervous system2. Only low expression levels are found in the brain and blood. The highest expression levels are found in the stomach fundus3.

Over-expression of 5-HT2B receptors in hearts of transgenic mice results in cardiac hypertrophy and decreased ventricular function due to enhanced extracellular matrix (ECM) and remodeling. Likewise, genetic deletion of 5-HT2B receptors was shown to lead to ventricular dilation and incomplete cardiac development5.

Last update: 12/08/2021

Anti-5HT2B Receptor (HTR2B) (extracellular) Antibody (#ASR-035) is a highly specific antibody directed against an epitope of the rat 5-HT-2B receptor. The antibody can be used in western blot and immunohistochemistry applications. It recognizes an extracellular epitope and can potentially detect 5HT2B receptor in living cells. It has been designed to recognize 5-hydroxytryptamine receptor 2B from rat, mouse and human samples.
