ملف بحث VIP / Vasoactive Intestinal Peptide
Vasoactive intestinal peptide is a 28-amino-acid neuropeptide studied through the VPAC1 and VPAC2 receptors and cyclic-AMP signaling. Research spans smooth-muscle response, vascular signaling, epithelial and barrier function, neuroimmune communication, cytokine regulation, airway models, and gastrointestinal physiology. VIP is a short-lived signaling peptide, so stability, assay timing, receptor expression, and delivery conditions strongly influence experimental results. It is selected when a project requires a native VPAC-receptor ligand rather than a general immune or vascular peptide. Its broad physiological literature provides mechanism context but should not be converted into disease, treatment, or personal-use claims for a catalog material.
الآلية المقترحة
Binds VPAC1 and VPAC2 receptors, activating Gs and cyclic AMP. Depending on tissue, this can produce smooth-muscle relaxation, vasodilation, altered epithelial secretion, and modulation of immune-cell cytokine signaling.
التأثيرات المذكورة في الدراسات
- Cell and animal studies report bronchodilatory, vasodilatory, epithelial, neuroprotective, and anti-inflammatory effects in selected models.
- Human physiology studies report vasodilation, changes in blood pressure or heart rate, flushing, and gastrointestinal or airway effects.
- VIP is rapidly degraded and has broad receptor distribution, making exposure, stability, and systemic effects difficult to control.

الأدلة والقيود
Physiology and receptor mechanisms are well characterized, but short half-life and broad systemic actions limit translation of model results.
