It is cosecreted with insulin from the pancreatic β-cells in the ratio of approximately 100:1 (insulin:amylin). Amylin plays a role in glycemic regulation by slowing gastric emptying and promoting satiety, thereby preventing post-prandial spikes in blood glucose levels

WebbImportantly, intraperitoneal inoculation of pancreatic homogenates containing IAPP aggregates into transgenic mice expressing human IAPP dramatically accelerates IAPP amyloid deposition, which was accompanied by clinical abnormalities typical of T2D, including hyperglycemia, impaired glucose tolerance, and a substantial reduction on β … WebbIAPP[19-37], accounting for 57% of IAPP- immunoreactivity in rat pancreas, is a major molecular form of rat IAPP moiety. A large amount of IAPP (328.5 ± 25.0 pmol/g wet weight) was found in rat pancreas and the peptide was also detected in pyloric antrum of stomach, duodenum, jejunum, ileum, and colon at 0.1-0.8% of the level of pancreas.
