Vasoactive Intestinal Peptide (VIP), also known as vasoactive intestinal polypeptide or PHM27, is a concise peptide hormone present in the gut, pancreas, and brain of various vertebrate species, including humans. It interacts with class II G protein-coupled receptors, exerting multiple effects such as:

Enhancing glycogen breakdown in the liver and muscles
Decreasing blood pressure
Inducing relaxation of smooth muscles in the gastrointestinal tract
Triggering contraction of cardiac muscles by augmenting both heart rate and the strength of contractions
Stimulating water secretion in different parts of the GI tract
Influencing vaginal lubrication
Regulating prolactin release
Safeguarding cartilage and neurons against ischemia and oxidative stress
Modulating autonomic nerve function
Assisting in the synchronization of the central nervous system, particularly neurons in the suprachiasmatic nucleus, with light cues to regulate circadian rhythms.
VIP has been a focus of extensive research due to its multifaceted functions, leading to a vast body of scientific literature. Despite the breadth of VIP-related studies, a noteworthy aspect is its ability to mitigate inflammation and fibrosis across various organs.
