VIP

VIP (Vasoactive Intestinal Peptide): The Master Neuromodulator & Systemic Regulator. Command the Multifunctional Signal of Homeostasis. VIP is not a single-target neurotransmitter; it is a 28-amino acid neuropeptide that acts as a primary neurotransmitter, neuromodulator, and potent vasodilator across the central nervous system and peripheral tissues. By binding to VPAC1 and VPAC2 receptors, it serves as a master regulator of neuroprotection, circadian rhythms, smooth muscle relaxation, and immune modulation. For neuroscientists, immunologists, and pulmonary researchers, VIP provides a critical key to understanding integrative physiology and cellular resilience. VIP's exceptionally broad research profile stems from its role as a pleiotropic signaling hub: ·Neurological System: Functions as a key neuroprotective agent, supporting neuronal survival, synaptic plasticity, and cerebral blood flow; central to research on Alzheimer's, Parkinson's, and circadian sleep disorders. ·Pulmonary & Cardiovascular Systems: Acts as a potent bronchodilator and vasodilator, relevant for studying asthma, pulmonary hypertension, and vascular function. ·Immune System: Modulates inflammatory responses, shifting macrophages to an anti-inflammatory (M2) phenotype and regulating T-cell activity. ·Digestive System: Influences gastrointestinal motility and secretion.
