Peptide YY (PYY) also known as peptide tyrosine tyrosine is a peptide that in humans is encoded by the PYY gene. Peptide YY is a short (36-amino acid) peptide released from cells in the ileum and colon in response to feeding. In the blood, gut, and other elements of periphery, PYY acts to reduce … See more Peptide YY is related to the pancreatic peptide family by having 18 of its 36 amino acids located in the same positions as pancreatic peptide. The two major forms of peptide YY are PYY1-36 and PYY3-36, which have PP fold … See more PYY is found in L cells in the mucosa of gastrointestinal tract, especially in ileum and colon. Also, a small amount of PYY, about 1-10%, is found in the esophagus, stomach See more Several studies have shown acute peripheral administration of PYY3-36 inhibits feeding of rodents and primates.

WebFor example, reduction of food intake by intraperitoneal injection of pancreatic polypeptide (PP) and peptide YY3–36 (PYY3-36), potential orexigenic peptides, was impaired in abdominal-vagotomized animals, 7,8 suggesting that PP and PYY3-36 impact anorexigenic effects through the action of vagal afferent nerves.
WebDec 6, 2024 · PYY(3–36) and PYY(3–36) both bind to the G-protein coupled receptors Y1 and Y2 with PYY(3–36) more potently activating the Y2 receptor [13,14]. PYY is known to downregulate gastrointestinal motility [ 15 ], cause intestinal vasoconstriction [ 16 ], and reduce appetite and body weight while improving glucose metabolism [ 17 ]. WebJul 8, 2004 · PYY 3-36 is a potent anorectic peptide hormone released from the L cells in response to feeding (46) and acts at a number of the Y receptors, particularly Y1, Y2, and Y5 (47).
