Description
Vasoactive Intestinal Peptide (VIP) is a 28-amino-acid neuropeptide widely distributed in the nervous, immune, and respiratory systems. It is studied for its roles in immune modulation, inflammation control, neuroprotection, and pulmonary health.
Benefits
- Immune modulation — studied for balancing Th1/Th2 responses and calming overactive immunity.
- Anti-inflammatory — explored for suppressing pro-inflammatory cytokine activity.
- Pulmonary health — interest in protecting lung function and airway relaxation.
- Neuroprotection — studied for safeguarding neurons and supporting brain signaling.
- Gut health — linked to regulation of intestinal smooth muscle and secretion.
What researchers look at
- VIP receptor activity (VPAC1/VPAC2) in immune and nervous system pathways.
- Clinical studies in asthma, pulmonary hypertension, and autoimmune conditions.
- Neuroprotective roles in models of neurodegeneration and brain injury.
- Exploration of gut-brain axis and intestinal immune modulation.
