Research record

Overview

Name: Vasoactive Intestinal Peptide (VIP)

Abbreviation: VIP

Classification: Endogenous neuropeptide / immunomodulatory peptide

Amino Acid Length: 28 amino acids

Family: Secretin / glucagon peptide family

Endogenous Presence: Naturally produced in the central nervous system, gastrointestinal tract, and peripheral nerves

VIP is a naturally occurring signaling peptide involved in vasodilation, immune regulation, smooth muscle relaxation, and neuroendocrine communication.

Mechanism of Action

VIP exerts its effects through activation of VPAC1 and VPAC2 receptors:

Stimulates adenylate cyclase → increases intracellular cAMP

Promotes smooth muscle relaxation and vasodilation

Regulates cytokine production

Modulates T-cell differentiation

Influences neurotransmission and gut motility

Key pathways:

Anti-inflammatory signaling via inhibition of TNF-α, IL-6, and IL-12

Promotion of regulatory T-cell activity

Enhancement of epithelial barrier integrity

Pulmonary vasodilation and bronchodilation
