Product Overview

VIP, or Vasoactive Intestinal Peptide, is a naturally occurring 28-amino-acid neuropeptide belonging to the secretin/glucagon peptide family.

VIP is widely distributed throughout the nervous system and peripheral tissues and has been investigated extensively for its role in cellular signaling, smooth-muscle activity, vascular responses, immune signaling, and gastrointestinal physiology.

As a research peptide, VIP provides a useful experimental model for studying neuropeptide signaling and interactions with VIP receptors and related G-protein-coupled receptor pathways.

Mechanism of Action

Research has investigated VIP in relation to several biological mechanisms:

VIP Receptor Signaling

VIP interacts primarily with VPAC1 and VPAC2 receptors, which are G-protein-coupled receptors involved in intracellular cyclic-AMP signaling.

Neurotransmitter & Neuropeptide Research

VIP has been investigated as a signaling molecule within the nervous system and in studies examining communication between neurons and peripheral tissues.

Vascular Signaling

Experimental research has examined VIP in relation to vascular smooth-muscle signaling and mechanisms involved in vascular tone.

Gastrointestinal Research

VIP has been studied in experimental models involving intestinal motility, secretion, and smooth-muscle activity.

Immune & Inflammatory Research

Research has investigated interactions between VIP signaling and immune-cell activity, cytokine pathways, and inflammatory responses.
