Peptide YY (PYY), human
Based on 1 Customer Validation
Peptide YY (PYY) is a gut hormone that regulates appetite and inhibits pancreatic secretion. Peptide YY (PYY) can mediate its effects through the Neuropeptide Y receptors.

Biologische Aktivität
Neuropeptide Y receptor[1]
The gut hormone peptide YY ( PYY) belongs to the pancreatic polypeptide (PP) family along with PP and neuropeptide Y (NPY). These peptides mediate their effects through the NPY receptors of which there are several subtypes (Y1, Y2, Y4, and Y5)[1]. Pancreatic polypeptide YY (Peptide YY), a small peptide consisting of 36 amino acids, is originally isolated from porcine intestine and is secreted from the neuroendocrine cells (L cells) in the mucosa of the gastrointestinal tract, but it has been localized to other locations associated with the digestive system[2].

Protokoll
Cats[3]
The inhibitory effects of Peptide YY on pancreatic exocrine secretion are studied by using an anesthetized adult (4 kg) cat. Infusion of secretin and CCK (1.5 units/ kg/hr each) in saline solution is made through the saphenous vein by using a perfusion pump at a flow rate of 10 ml/hr. Infusion or single injection of Peptide YY (10-250 pmol/kg) is also made through the saphenous vein. Pancreatic juice from the cannulated pancreatic duct is collected in test tubes for 10-min periods by using a fraction collector. The volume of the juice and A280 are measured. Bicarbonate is determined by the titration method[3].
Rabbits[2]
New Zealand White rabbits are fed an atherogenic diet and control animals fed a normal diet for 4 weeks. Immunohistochemistry is used to determine the localization of Peptide YY and eNOS in the aorta. The aorta, carotid, renal, iliac, inferior mesenteric, and renal interlobular arteries are removed, mounted in organ baths, and subjected to doses of Peptide YY (1-100 nM) and then acetylcholine (1 μM)[2].
