VIP (Vasoactive Intestinal Peptide): An Immune and Vascular Research Guide
What is VIP?
VIP (vasoactive intestinal peptide) is a 28-amino-acid neuropeptide found throughout the body, originally identified in the gut but now recognised as a widespread signalling molecule. It acts as both a neurotransmitter and a hormone, and it is studied for a notably broad range of effects spanning the vascular system, the immune system and the regulation of inflammation. This breadth of activity is the basis of its research interest.
Studied mechanisms of action
In research models, VIP acts at the VPAC1 and VPAC2 receptors, G-protein-coupled receptors expressed in blood vessels, immune cells and many tissues. Through these receptors it is studied for relaxing vascular smooth muscle (its original vasodilatory effect), for modulating the activity of immune cells, and for shifting inflammatory signalling toward a more regulated, anti-inflammatory profile. Because it influences both the vascular and immune systems, VIP is used as a research tool to study the connections between circulation, immunity and inflammation.
The state of the research
VIP has a substantial scientific literature in physiology, neuroscience and immunology, where it is a well-characterised signalling peptide. Within the research-compound community its use is experimental and model-dependent, and its short half-life and broad receptor distribution are relevant considerations. Results remain preclinical.
Handling & storage for research
Supplied as a lyophilised powder. Store sealed vials cold and protected from light; reconstitute with bacteriostatic water for laboratory handling and keep the reconstituted solution refrigerated, using it within the appropriate window. Avoid repeated freeze-thaw cycles and vigorous agitation. Every Aura Labs batch ships with a third-party certificate of analysis confirming identity and purity above 99%.
