Originally isolated from the porcine small intestine by Said and Mutt in 1970, vasoactive intestinal peptide (often abbreviated as VIP) is a 28-amino-acid peptide.VIPis produced in many tissues of vertebratesincluding the gut, pancreas, neocortex, and suprachiasmatic nuclei of the hypothalamus in the brain. VIP ... It belongs to a family of neuropeptides and has been a subject of extensive research due to its pleiotropic effectsVasoactive intestinal peptide produces long-lasting .... The initial discovery highlighted its significance in the gastrointestinal system, but subsequent investigations have revealed its production in a much broader spectrum of locations.

VIP is produced in many tissues of vertebrates, extending far beyond the digestive tract. Research has pinpointed its synthesis and secretion within the central nervous system, particularly in the hypothalamus and anterior pituitary. Here, it plays a role in regulating various neuroendocrine functions. High levels of vasoactive intestinal peptide are found in the neurons of the suprachiasmatic nucleus (SCN), a key area for the regulation of circadian rhythms.

Beyond the nervous system, VIP is produced by specialized cells within the endocrine system.作者：MG Bryant·1978·被引用次数：5—splanchnic vasodilatorypeptidefrom hog small by Grossman et al.

Studies have shown that VIP derived from pigs, cows, and rats share the same fundamental structure, underscoring its conserved biological importance across different mammalian species. This conservation allows for comparative studies and a deeper understanding of its mechanisms.Synthesis of the vasoactive intestinal peptide (VIP)

The term vasoactive intestinal polypeptide (VIP) is often used interchangeably with vasoactive intestinal peptide.Like other gastrointestinal peptides,vasoactive intestinal polypeptide (VIP) is synthesized as a precursor molecule of 170 amino acids containing a signal ... This peptide is synthesized as a precursor molecule, a larger polypeptide of 170 amino acids, which is then processed to yield the active 28-amino-acid peptide. The production of this peptide is a sophisticated biological process.

In the context of specific medical conditions, Vasoactive intestinal peptide-producing tumor tissue fragments have been identified, most notably in the case of VIPomasVasoactive intestinal peptide. These tumors, often found in the pancreas, secrete excessive amounts of VIP into the bloodstream, leading to a condition characterized by watery diarrhea, hypokalemia, and achlorhydria, known as Verner-Morrison syndrome. A Vasoactive intestinal peptide test can be performed to measure VIP levels in the blood, aiding in the diagnosis of such conditions.

The distribution of VIP is extensive, and it is secreted by cells throughout the intestinal tract, contributing to its role in regulating gastrointestinal function, including fluid and electrolyte secretion. Its presence is also noted in the adrenal glands, heart, and other organs. Therefore, understanding the multifaceted production of this peptide is key to appreciating its wide-ranging physiological and pathological implications.

In summary, vasoactive intestinal peptide is a widely distributed neuropeptide produced by a variety of cell types and tissues. From the neurons of the brain and the endocrine cells of the gastrointestinal system to immune cells and even tumor cells, the origins of VIP are diverse. This broad distribution highlights its critical role in numerous bodily functions, including neurotransmission, endocrine regulation, immune modulation, and gastrointestinal physiology. The ongoing research into Vasoactive Intestinal Peptide continues to unveil its complex synthesis and release mechanisms, further solidifying its importance in human health.
