VIPmedical hormone Vasoactive intestinal peptide (VIP) is a crucial 28-amino acid peptide with widespread physiological functions, acting as both a neurotransmitter and a hormone.VIP (Vasoactive Intestinal Peptide) Antibody Originally identified for its potent vasodilator properties, VIP is involved in regulating a diverse array of processes throughout the body, from gastrointestinal function to immune responses and even brain activityVasoactive Intestinal Polypeptide (VIP). Understanding VIP's multifaceted roles is essential for grasping its implications in various physiological and pathological conditions.Vasoactive intestinal peptide, also known as vasoactive intestinal polypeptide or VIP,is a peptide hormone that is vasoactive in the intestine.
VIP's biological actions are extensive, stemming from its ability to bind to specific receptors (PACAP subfamily of class B1 G protein-coupled receptors). Its name reflects one of its primary roles: it is vasoactive in the intestine, promoting vasodilation and thus influencing blood flow. Beyond this, VIP serves as a potent smooth muscle relaxant, contributing to the regulation of various organ systems, including the gastrointestinal tract, where it can stimulate the secretion of water and electrolytes. Research also indicates VIP's involvement as a bronchodilator, suggesting a role in respiratory function作者：RA Simon·2021·被引用次数：15—We hypothesizedplasma VIP levelsto be associated with symptoms of anxiety and depression, as well as brain volume and resting-state functional connectivity..
Furthermore, VIP acts as a neuromodulator and neurotransmitter, widely distributed in both the central and peripheral nervous system. This broad distribution underpins its influence on a range of neurological functions. Emerging research also highlights VIP's potential in modulating immune responses, with studies suggesting it may possess anti-inflammatory activities and can decrease inflammatory cytokines, offering a protective effect in conditions like arthritis.VIP, a 28-amino-acid polypeptide secreted by cells throughout the intestinal tract.

The physiological importance of VIP translates into significant clinical relevance, particularly in the context of certain tumors. Elevated levels of VIP can be indicative of vasoactive intestinal polypeptide-secreting tumors (VIPomas)VIP - Vasoactive intestinal peptide - Homo sapiens (Human). These neuroendocrine tumors, often found in the pancreas or duodenum, can lead to a syndrome characterized by profuse secretory diarrhea, hypokalemia, and gastric acid hypersecretion, sometimes referred to as Verner-Morrison syndrome.
To aid in the diagnosis and monitoring of such conditions, a Vasoactive intestinal peptide test is available. This blood test measures the amount of VIP in the blood. For accurate results, specific preparation instructions are often required, such as fasting for 10-12 hours prior to specimen collection and avoiding certain medications that could affect intestinal function. The test is crucial for detecting VIP-producing tumors in patients presenting with chronic diarrheal diseases.
The scientific community continues to explore the intricate workings of VIPVasoactive Intestinal Peptide (VIP) | Spartanburg Regional. Studies have investigated the association of plasma VIP levels with conditions such as anxiety and depression, suggesting a potential link between VIP and mood regulation, as well as its influence on brain volume and functional connectivity. The synthesis of VIP has been a subject of scientific inquiry since the 1970s, underscoring its long-standing recognition as a key regulatory peptide.
Ongoing research into VIP's diverse functions, from its roles in smooth muscle relaxation and vasodilation to its immunomodulatory and potential therapeutic effects, promises to deepen our understanding of this vital peptide. As our knowledge expands, so too may the clinical applications derived from targeting or monitoring VIP in various health and disease states.010397: Vasoactive Intestinal Polypeptide (VIP), Plasma
