N2 - Glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) are the incretin hormones secreted from enteroendocrine K-cells and L-cells, respectively, by oral ingestion of various nutrients including glucose. K-cells, L-cells and pancreatic β-cells are glucose-responsive cells with similar glucose-sensing machinery including glucokinase and an adenosine triphosphate-sensitive K+ channel comprising KIR6.2 and sulfonylurea receptor 1. However, the physiological role of the adenosine triphosphate-sensitive K+ channel in GIP secretion in K-cells and GLP-1 secretion in L-cells is not elucidated. Recently, it was reported that GIP and GLP-1-producing cells are present also in pancreatic islets, and islet-derived GIP and GLP-1 contribute to glucose-induced insulin secretion from pancreatic β-cells. In this short review, we focus on GIP and GLP-1 secretion by monosaccharides, such as glucose or fructose, and the role of the adenosine triphosphate-sensitive K+ channel in GIP and GLP-1 secretion.
