  The role of peptide YY in gastrointestinal diseases and …

  20121221 · The release of PYY from intestinal endocrine cells is stimulated by intraluminal nutrients, lipids, short-chain fatty acids, glucose, amino-acids, and bile salts. PYY release can also be mediated via a neural reflex involving the vagus nerve, as well as by other gut neuroendocrine peptides such as vasoactive intestinal peptide (VIP), …

  Endogenous PYY and GLP-1 mediate L-glutamine responses …

  20131015 · Background and Purpose. l -glutamine (Gln) is an energy source for gastrointestinal (GI) epithelia and can stimulate glucagon-like peptide 1 (GLP-1) release from isolated enteroendocrine L-cells. GLP-1 and peptide YY (PYY) are co-secreted postprandially and both peptides have functional roles in glucose homeostasis and …

  Fermentable carbohydrate stimulates FFAR2-dependent colonic PYY cell ...

  2016114 · Within the gastrointestinal tract, FFAR2 and 3 have been localized to enteroendocrine L cells [17]. These specialized gut cells secrete the anorectic hormone peptide YY (PYY) and the incretin glucagon-like peptide-1 (GLP-1) in response to luminal nutrients, such as sugars, amino acids, and long-chain fatty acids [17], [21], [22].

  Effects of 2 Novel PYY(1-36) Analogues, (P3L31P34)PYY(1-36) and PYY(1 ...

  2019617 · In this regard, recent studies have confirmed a positive effect of PYY on beta-cell survival and overall function, linked to the activation of NPYR1s. 10, 11 Thus, PYY (1-36) has been shown to enhance the growth and survival of beta-cells, 8 ultimately leading to enhanced glycaemic control. 12 In agreement with this, the ablation of PYY-expressing …

  SCFAs strongly stimulate PYY production in human enteroendocrine cells

  201818 · Peptide-YY (PYY) and Glucagon-Like Peptide-1 (GLP-1) play important roles in the regulation of food intake and insulin secretion, and are of translational interest in the field of obesity and diabetes. PYY production is highest in enteroendocrine cells located in the distal intestine, mirroring the …

  Colocalization of the -subunit of gustducin with PYY and …

  2006221 · G gust-positive cells (left) located in either the glandular or surface epithelium of the colon colocalized with PYY (middle) as shown in the merged image (overlay; right). The arrows point to representative cells that coexpressed G gust and PYY immunoreactivity. The insets show cells in the surface epithelium.
