Vasoactive Intestinal Peptide in the Hypothalamus and Pituitary

Neuroendocrinology, 2008
Data are presented to show that vasoactive intestinal peptide (VIP) is synthesized and secreted by the hypothalamus and anterior pituitary and that it participates in the regulation of pituitary functions. Immunoreactive VIP in the hypothalamus and pituitary is increased following estrogen treatment and adrenalectomy and is reduced in ...

Vasoactive Intestinal Peptide and Nerve Regeneration

Journal of Hand Surgery, 1991
The role of vasoactive intestinal peptide (V.I.P.) in nerve regeneration was investigated by assessing the changes in immunoreactive V.I.P. levels in rat sciatic nerves following injury and repair. 60 rats were divided into three surgical groups and one control group: In group I (primary repair), sciatic nerves were divided and immediately repaired; in

Vasoactive intestinal peptide producing neuroblastoma

Journal of Pediatric Surgery, 1982
The Verner-Morrison syndrome has been described in 19 previous patients with ganglioneuroma and ganglioneuroblastoma but never neuroblastoma. Its occurrence following treatment of a neuroblastoma with chemotherapy with maturation of the tumor has only been reported on one previous occasion.

Stabilization of Vasoactive Intestinal Peptide by Lipids

The Journal of Pharmacology and Experimental Therapeutics, 1998
An anionic phospholipid, phosphatidylglycerol (PG), induced vasoactive intestinal peptide (VIP) to adopt a helical conformation, determined by circular dichroism studies. PG inhibited the trypsin-catalyzed, antibody-catalyzed and uncatalyzed cleavage of VIP, measured by radiometric and HPLC methods.

Vasoactive intestinal peptide in cerebrospinal fluid

Peptides, 1984
Immunoreactive vasoactive intestinal peptide (VIP) was measured in lumbar and ventricular cerebrospinal fluid (CSF) from patients with various neurological disorders and in 2 hour aliquots of cisternal fluid removed continuously from rhesus monkeys. Although most of the VIP in concentrated pools of human ventricular fluid and of monkey cisternal fluid ...

Vasoactive Intestinal Peptide–Secreting Tumors

Pancreas, 2019
Abstract Vasoactive intestinal peptide–secreting tumors (VIPomas) are a group of rare neuroendocrine tumors, which cause a typical syndrome of watery diarrhea. Most of these tumors are found in the pancreas and are usually detected at a later stage.

Autoregulation of neuroblastoma growth by vasoactive intestinal peptide

Journal of Pediatric Surgery, 1992
Elevated serum levels of vasoactive intestinal peptide (VIP) are associated with some cases of neuroblastoma and correlate with a favorable prognosis. VIP has previously been shown in our laboratory to cause the in vitro growth inhibition and morphological differentiation of the human neuroblastoma cell line, LA-N-5.

Transmitter Role of Vasoactive Intestinal Peptide

Pharmacology & Toxicology, 1993
Abstract: Vasoactive intestinal polypeptide (VIP) is a 28 amino acid with a wide‐spread neuronal localization. VIP fulfils many of the classical criteria for neurotransmission. In the cerebral cortex bipolar VIP neurones are involved in the coupling between energy metabolism, blood flow and neuronal activity. Furthermore, VIP in the brain plays a role
