Vasoactiveintestinal peptidedosage Vasoactive intestinal peptide (VIP) is a crucial neuropeptide with widespread distribution throughout the body, playing significant roles in both the central and peripheral nervous systems, as well as the gastrointestinal tract2024年9月19日—Detectingvasoactive intestinal polypeptide-producing tumorsin patients with chronic diarrheal diseases.. Originally identified for its potent vasodilator properties, VIP is a 28-amino acid polypeptide that acts as a neurotransmitter and neuromodulator, influencing a diverse array of physiological processes. Its functions extend to regulating smooth muscle relaxation, stimulating water secretion in the pancreas and bile, and inhibiting gastric acid secretion. Understanding the multifaceted nature of VIP is essential for comprehending its involvement in various bodily functions and potential pathological conditions.
VIP is a peptide hormone that is widely distributed, not just in the intestine but also in the pancreas and the central nervous system. It is found in neurons within the gastrointestinal system and also within the central and peripheral nervous systems, acting as a nonadrenergic, noncholinergic neurotransmitter. This broad presence allows VIP to exert influence over numerous bodily systems, from digestive processes to neural signaling.VIP - Overview: Vasoactive Intestinal Polypeptide, Plasma Its origin as a gut peptide hormone, initially reported as a vasodilator, highlights its primary role in regulating vascular tone and intestinal functions.
The functions of vasoactive intestinal peptide are extensive and varied.Vasoactive intestinal peptide: cardiovascular effects As its name suggests, VIP is a potent vasodilator, meaning it relaxes blood vessels, thereby increasing blood flow. Beyond its cardiovascular effects, VIP acts as a bronchodilator and a smooth muscle relaxant, contributing to the regulation of respiratory and digestive tract motility. It also plays a significant role in fluid and electrolyte balance, stimulating the secretion of water into pancreatic juice and bile, while inhibiting gastric acid secretion and absorption from the intestine. Furthermore, VIP modulates the activity of various immune system cells and has been identified as a mitogen for embryonic cells.It is a vasodilator, bronchodilator and smooth muscle relaxant. It modulates the activity of many immune system cell types. It is a mitogen for embryonic ...
Emerging research also points to VIP's involvement in hormonal regulation, potentially acting as an important factor in the biosynthesis of testosterone and the secretion of follicle-stimulating hormone (FSH). Its presence in the enteric nervous system underscores its importance as a neurotransmitter in gastrointestinal motility and secretion.
Disruptions in VIP levels or function can be associated with certain medical conditions. Notably, VIP-producing tumors, known as VIPomas, can lead to severe symptoms, including chronic diarrheal diseases due to excessive VIP secretion. Measuring VIP levels in the blood is a diagnostic tool used to detect such tumors, though they are extremely rare.2023年10月4日—Chemical Identifiers· UNII: 6J2WVD66KR · CAS number: 37221-79-7 · InChI Key: VBUWHHLIZKOSMS-RIWXPGAOSA-N · InChI · IUPAC Name · SMILES. CC[C@H]( ... The potential clinical applications of VIP and its analogs are being explored for a range of conditions, including tumors, diabetes, inflammatory bowel diseases, sepsis, rheumatoid arthritis, and neurodegenerative disorders. The pleiotropic effects of VIP suggest its broad therapeutic potential.
