生物活性

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.

IC50 & Target

Neuropeptide Y receptor[1]
体外研究
(In Vitro)

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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

Peptide YY is capable of strongly inhibiting secretin-stimulated pancreatic secretion. A very low dose of Peptide YY (10-20 pmol/kg) significantly decreases the pancreatic secretion of bicarbonate as well as fluid that is stimulated by a single dose of secretin (0.1 unit/kg). A dose of Peptide YY of 100-200 pmol/kg causes a 70-80% reduction of the pancreatic bicarbonate and fluid secretion[3]. Peptide YY is localised to blood vessels and atherosclerotic plaques of rabbits. It causes vasoconstriction of the vascular tree[2].

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
