Originally isolated from porcine small intestine in 1970 by Said and Mutt, vasoactive intestinal polypeptide (VIP) has since been identified in numerous vertebrate systems. Research indicates that VIP is synthesized and secreted by many tissues of vertebrates, including significant production within the gut, pancreas, neocortex, and crucially, the suprachiasmatic nuclei of the hypothalamus in the brain. This broad distribution underscores its importance in both the central and peripheral nervous systems.VIP - Overview: Vasoactive Intestinal Polypeptide, Plasma

Within the brain, VIP holds particular significance010397: Vasoactive Intestinal Polypeptide (VIP), Plasma. It is synthesized and secreted by the hypothalamus and anterior pituitary, where it participates in the regulation of various bodily processes. Specifically, VIP is also produced in the suprachiasmatic nuclei (SCN) of the hypothalamus, a region vital for regulating circadian rhythms. The presence of VIP in the hypothalamic and extrahypothalamic regions of the brain further emphasizes its role as a critical signaling molecule within the central nervous system.

Beyond the brain, the pancreas is another major site of VIP production.作者：RF Harty·1988·被引用次数：1—Vasoactive intestinal peptide-producingtumor tissue fragments obtained at surgery were maintained in short-term culture.

This association is so strong that pancreatic vasoactive intestinal peptide-producing tumors, known as VIPomas, are a recognized clinical entity. In fact, most (90%) of these rare functional neuroendocrine tumors are located in the pancreas, often presenting with symptoms related to excessive VIP release. VIP is also found in other gastrointestinal tissues, being secreted by cells throughout the intestinal tract. Historically, the pig small intestine was a key source for early research into this peptide.Recent advances in vasoactive intestinal peptide physiology ...

In summary, the production of vasoactive intestinal peptide is a complex and distributed phenomenonMechanisms of vasoactive intestinal peptide release in .... From its initial discovery in the swine duodenum and porcine small intestine, our understanding has expanded to recognize its synthesis in the hypothalamus and anterior pituitary, pancreatic islet $\alpha$-cells, diverse neurons, immune cells, and endocrine cells, and throughout the gastrointestinal (GI) tract. This extensive network of production sites allows VIP to exert its pleiotropic effects, influencing a wide array of physiological functions throughout the body. The production of this vital peptide is a testament to the interconnectedness of biological systems.
