VIP
Vasoactive Intestinal Peptide (VIP) is a 28-amino acid neuropeptide that activates VPAC1 and VPAC2 receptors (class B GPCRs). It plays roles in vasodilation, smooth muscle relaxation, neuromodulation, circadian rhythm regulation, and immune signaling. Research examines its broad-spectrum effects across multiple organ systems.
