VIP, short for vasoactive intestinal peptide, is a naturally occurring neuropeptide found throughout the nervous, digestive, respiratory, and immune systems. It communicates through the VPAC1 and VPAC2 receptors and plays a role in several important biological signaling pathways.

Research involving VIP commonly focuses on:

• Immune system regulation
• Inflammatory signaling
• Blood vessel relaxation and circulation
• Respiratory and airway function
• Intestinal movement and digestive activity
• Gut barrier signaling
• Communication between the nervous and immune systems

VIP is especially studied for its ability to influence inflammatory activity while supporting communication between the brain, immune system, lungs, and digestive tract. It remains an investigational compound, and its potential applications continue to be evaluated in laboratory and clinical research.
