Overview

What it is.

VIP (Vasoactive Intestinal Peptide) is a naturally occurring neuropeptide distributed across the gut, lungs, and central nervous system, studied for its role in airway-smooth-muscle signaling and vasodilation-related research questions. It's also referenced in immune-modulation and neuroimmune-signaling research literature.

Research Areas

  • Studied for its potential role in airway-smooth-muscle and pulmonary-signaling research
  • Studied for its potential role in immune-modulation and neuroimmune-signaling research
  • Studied more broadly as a neuropeptide across gut-brain and vasodilation-related research pathways

Research Deep-Dive

How it works.

VIP (Vasoactive Intestinal Peptide) is a naturally occurring neuropeptide distributed across the gut, lungs, and central nervous system, studied for a wide range of signaling roles spanning smooth-muscle regulation, immune modulation, and neuroimmune communication.

It's studied for engaging VIP receptors on smooth-muscle and immune cells, triggering relaxation of airway smooth muscle and modulating cytokine signaling in immune cells — a broad distribution and receptor profile that makes it a subject of research across several distinct physiological systems at once.

Use Cases Explored

  • Studied for its potential role in airway-smooth-muscle and pulmonary-signaling research
  • Studied for its potential role in immune-modulation and neuroimmune-signaling research
  • Studied more broadly as a neuropeptide across gut-brain and vasodilation-related research pathways

The Evidence

Established neuropeptide literature

VIP's distribution and receptor pharmacology are well characterized across decades of neuropeptide research, spanning pulmonary, gastrointestinal, and immunological research contexts.

Breadth-versus-depth tradeoff

Because VIP is studied across so many different physiological systems, evidence for any single research application (for example, pulmonary versus immune) is generally less deep than for peptides with a narrower, more focused research footprint.

Questions

VIP FAQ

What is VIP studied for?+

VIP (Vasoactive Intestinal Peptide) is studied for its role in airway-smooth-muscle and pulmonary-signaling research, immune-modulation and neuroimmune-signaling research, and broader gut-brain and vasodilation-related pathways.

What does 'VIP' stand for and where is it found naturally?+

It stands for Vasoactive Intestinal Peptide — a naturally occurring neuropeptide distributed across the gut, lungs, and central nervous system.

How should VIP be handled and stored?+

It ships as a lyophilized powder. Reconstitute with bacteriostatic water and refrigerate at 2–8°C after mixing — good for roughly 4–6 weeks refrigerated, or up to 24 months unreconstituted in a cool, dry place.

What testing does this batch undergo?+

Every batch is HPLC tested for purity and identity, plus sterility and endotoxin screening, before release. The Certificate of Analysis for that lot ships with your order.
