Background: Peptide YY

Peptide YY (PYY), a secretory peptide, is expressed by L cells (enteroendocrine cells) in the small and large intestine, Islet of Langerhans cells, testis, and in some central and peripheral neurons. Because PYY is released from L cells after feeding, it is thought to produce a satiety signal. While the regulation of appetite by PYY and GLP-1 have been studied extensively, recent evidence supports a role for PYY in Islet of Langerhans beta cell survival. PYY secretion is also modulated by gut microbiota, and levels of colonic PYY have reduced in rats with DSS-induced colitis, and in humans with inflammatory bowel disease (IBD), while circulating PYY increased in IBD.
