Peptide YY inhibits intestinal Cl- secretion in experimental porcine cryptosporidiosis through a prostaglandin-activated neural pathway.
Peptide YY (PYY) is a powerful inhibitor of intestinal secretion mediated by cAMP agonists such as vasoactive intestinal peptide and prostaglandin E2. We hypothesized that PYY would attenuate the secretory diarrhea in piglet cryptosporidiosis, which is mediated by prostaglandins E2 and I2. Control and infected ileal tissues from piglets were studied in Ussing chambers. The addition of PYY to th...
متن کاملPeptide YY inhibits vasopressin-stimulated chloride secretion in inner medullary collecting duct cells.
mIMCD-k2 cells are derived from the inner medullary collecting duct of a mouse and exhibit electrogenic sodium absorption and cAMP- and vasopressin (AVP)-stimulated electrogenic chloride secretion [N. L. Kizer, B. Lewis, and B. A. Stanton. Am. J. Physiol. 268 (Renal Fluid Electrolyte Physiol. 37): F347-F355, 1995; and N. L. Kizer, D. Vandorpe, B. Lewis, B. Bunting, J. Russell, and B. A. Stanton...
متن کاملCharacterization of brainstem peptide YY (PYY) neurons.
Peptide YY (PYY), a member of the NPY superfamily of peptides, is predominantly synthesized by the colon and is thought to act on both the gut and brain to modulate energy homeostasis. Although neurons expressing PYY mRNA have also been reported in the brainstem, little is known about their physiological role and study of their projections has been problematic due to crossreactivity of PYY anti...
متن کاملPlasma and tissue alterations of peptide YY and enteroglucagon in rats after colectomy.
Peptide YY (PYY) and enteroglucagon are produced by endocrine cells of the colonic mucosa. PYY inhibits upper gastrointestinal motility, and enteroglucagon is trophic for small bowel mucosa. Adaptive increase in the production and release of these peptides may improve functional results after colorectal resections. We hypothesized that if segments of the colon were resected, then production and...
متن کاملSomatostatin receptor subtype-5 mediates inhibition of peptide YY secretion from rat intestinal cultures.
Somatostatin-14 (S-14) and somatostatin-28 (S-28) bind to five distinct membrane receptors (SSTRs), but S-28 has higher affinity for SSTR-5. Whether S-28 acting through SSTR-5 regulates inhibition of peptide YY (PYY) secretion was tested in fetal rat intestinal cell cultures. S-28 and S-14 caused dose-dependent inhibition of PYY secretion stimulated by gastrin-releasing peptide, but S-28 was mo...
