Vasoactive Intestinal Polypeptide Receptor 2 (VIPR2) Antibody

Background

VIPR2 is a G protein-coupled receptor activated by vasoactive intestinal peptide (VIP), a neuropeptide that plays a central role in regulating smooth muscle relaxation, vasodilation, and neurotransmission. VIPR2 primarily couples to Gs proteins, activating adenylate cyclase, which increases intracellular cAMP levels and leads to the relaxation of smooth muscle cells and dilation of blood vessels. It is expressed in the smooth muscle of the gastrointestinal tract, heart, lungs, and brain. VIPR2 has significant roles in regulating gastrointestinal motility, vascular tone, and immune cell activity. Dysregulation of VIPR2 signaling is implicated in diseases such as asthma, irritable bowel syndrome (IBS), and inflammatory disorders. VIPR2 antagonists are being studied for their potential in treating these diseases, as they could help reduce excessive smooth muscle contraction and inflammation.
