Vasoactive Intestinal Peptide Receptor 1 (VIPR1) Antibody

Background

VIPR1 is a G protein-coupled receptor activated by vasoactive intestinal peptide (VIP), a neuropeptide involved in regulating smooth muscle relaxation, vasodilation, and neurotransmission. VIPR1 couples to Gs proteins, stimulating adenylate cyclase and increasing cAMP levels, leading to relaxation of smooth muscle cells, dilation of blood vessels, and modulation of gastrointestinal motility. VIPR1 is primarily expressed in the smooth muscle of the gastrointestinal tract, blood vessels, and the central nervous system, where it plays a role in regulating vascular tone, intestinal motility, and neurotransmitter release. VIP has a significant role in regulating inflammation and immune responses, and VIPR1 signaling is involved in modulating immune cell functions. Dysregulation of VIPR1 signaling has been implicated in inflammatory diseases, gastrointestinal disorders, and cardiovascular diseases. Agonists targeting VIPR1 are being investigated for their potential to treat diseases involving smooth muscle contraction and inflammation, such as asthma, irritable bowel syndrome (IBS), and hypertension.
