Functional Vasoactive Intestinal Polypeptide (VIP) Receptors in Human Neuroblastoma Subclones That Contain VIP Precursor mRNA and Release VIP-like Substances

Vasoactive intestinal peptide (VIP).

In 1969, Said and Mutt reported the extraction from secretion, increased flow of alkaline pancreatic normal lung tissue of a peptide which was capable juice and small intestinal juice with increased cyclic of causing gradual but prolonged peripheral AMP content (Makhlouf and Said, 1975), overlap vasodilation. This finding led them to search for markedly with the actions of the other three pepti...

Vasoactive Intestinal Peptide (VIP) and VIP Receptors-Elucidation of Structure and Function for Therapeutic Applications

Vasoactive intestinal peptide (VIP) is a 28-amino acid polypeptide first isolated from swine duodenum. VIP is a neurotransmitter that is extensively distributed in tissues. According to published reports, VPAC1 and VPAC2 act as VIP receptors and are widely present in the central nervous system and peripheral tissues. VIP exerts diverse actions on the cardiovascular system, pancreas, digestive t...

Cyclical release of vasoactive intestinal polypeptide (VIP) from a pancreatic islet cell apudoma.

A patient is described who presented with the classical symptomatology and profound electrolyte disturbance of the Verner-Morrison syndrome due to a pancreatic apudoma secreting vasoactive intestinal polypeptide (VIP). Diagnosis was confirmed by plasma VIP as measured by a radio-immunoassay technique now available. It is suggested that the cyclical nature of the symptoms in this case was due to...

Vasoactive Intestinal Polypeptide (VIP) Regulates Metabolic Processes in Human and Murine Adipocytes by Modulating PPARγ Expression

Evidence that vasoactive intestinal polypeptide (VIP) mediates neurogenic vasodilation of feline cerebral arteries.

In this study the magnitude of non-sympathetic, non-cholinergic neurogenic vasodilation of feline cerebral arteries in vitro was correlated with the extent of innervation by VIP-immunoreactive nerves. Well-innervated arteries underwent nerve-mediated relaxation whereas those that are not supplied with VIP-containing axons did not relax to transmural nerve stimulation. The relaxation of cerebral...
