• gastric
  • VIP has an effect on several tissues: With respect to the digestive system, VIP seems to induce smooth muscle relaxation (lower esophageal sphincter, stomach, gallbladder), stimulate secretion of water into pancreatic juice and bile, and cause inhibition of gastric acid secretion and absorption from the intestinal lumen. (wikipedia.org)
  • Gastric sodium loading results in an increase in the portal venous concentration of vasoactive intestinal peptide (VIP) and down-regulation of both the intrahepatic and circulating renin-angiotensin systems. (clinsci.org)
  • K cells secrete gastric inhibitory peptide, an incretin, which also promotes triglyceride storage. (wikipedia.org)
  • vitro
  • Vasoactive intestinal peptide (VIP) has been shown to enhance steroid production in vivo in rabbits (1) and humans (2) and in vitro in prepubertal rat ovaries (3), isolated rat granulosa cells (4), as well as cultured baboon granulosa cells (5). (springer.com)
  • gastrin releasi
  • The vagus nerve (CN X) also releases gastrin releasing peptide onto G cells. (wikipedia.org)
  • The G cells secrete gastrin, post-ganglionic fibers of the vagus nerve can release gastrin-releasing peptide during parasympathetic stimulation to stimulate secretion. (wikipedia.org)

  • Comparison of an 18 F labeled deravative of vasoactive intestinal peptide and 2-deoxy-2-[ 18 F)fluoro-D-glucose in nude mice bearing breast cancer xenografts," Molecular Imaging and Biology , vol. 4, no. 5, pp. 369-379, 2002. (hindawi.com)
  • intestine
  • The intestinal phase: The remaining 10% of acid is secreted when chyme enters the small intestine, and is stimulated by small intestine distension and by amino acids. (wikipedia.org)
  • porcine
  • Galanin was first identified from porcine intestinal extracts in 1978 by Professor Viktor Mutt and colleagues at the Karolinska Institute, Sweden using a chemical assay technique that detects peptides according to its C-terminal alanine amide structure. (wikipedia.org)
  • regulatory
  • This demonstrates that it is essential to study the effects of galanin and other regulatory peptides in their autologous species. (wikipedia.org)
  • Murine
  • We demonstrate here that administration of a hybrid peptide antagonist that blocks VIP signaling enhances CD8 T cell responses in a murine model of AML. (jimmunol.org)
  • infections
  • Rates tend to be higher in the developed world with some proposing this to be the result of less exposure to intestinal infections, or a Western diet and lifestyle. (wikipedia.org)
  • role
  • The discrete pattern of hybridization for VIP/PHI mRNA indicates that these two peptides are synthetized in rat retina and SCN and suggests that they may play a key role in the photic entrainment to the SCN regulating various circadian rhythms. (springer.com)
