Peptide YY (PYY) 是一种肠道激素，可调节食欲和抑制胰腺分泌。Peptide YY (PYY) 可以通过神经肽 Y 受体 (Neuropeptide Y receptors) 介导其作用。

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.

Neuropeptide Y receptor

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

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. Peptide YY is localised to blood vessels and atherosclerotic plaques of rabbits. It causes vasoconstriction of the vascular tree. has not independently confirmed the accuracy of these methods. They are for reference only.
