Researchers apply VIP to investigate its potent activation of VPAC receptors, resulting in elevated intracellular cAMP and relaxation of vascular and non-vascular smooth muscle. Pre-clinical findings in isolated vessel preparations and gastrointestinal tissue models indicate dose-dependent vasodilation, inhibition of contractile responses, and stimulation of secretory functions.
This neuropeptide facilitates examination of receptor-mediated signaling cascades, modulation of smooth muscle tone, and coordinated neuroendocrine effects in models of vascular or digestive physiology.
Scientific Overview of VIP Applications
Pre-clinical models illustrate VIP’s engagement with receptor and effector pathways:
- Activation of VPAC1 and VPAC2 receptors leading to cAMP accumulation and smooth muscle relaxation in vascular and gastrointestinal tissue preparations. https://pubmed.ncbi.nlm.nih.gov/22289055/
- Stimulation of intestinal fluid secretion and pancreatic bicarbonate release in exocrine gland models.
- Modulation of inflammatory mediator expression and immune cell responses in mucosal and pulmonary systems. https://pubmed.ncbi.nlm.nih.gov/14757212/
- Support for investigations into neuroprotective effects and anti-apoptotic signaling in neuronal stress models.
- Examination of pulmonary vasodilation and airway smooth muscle relaxation in respiratory physiology research.
- Contribution to studies on circadian rhythm regulation and neuroendocrine integration across central and peripheral systems.
