IAPP is a normal product of the pancreatic islet β-cell and is stored along with insulin in secretory granules ( 35 – 38 ). Reproduced material should be attributed as follows: If the material has been adapted instead of reproduced from the original RSC publication This pathological characteristic is most probably of great importance for the development of the β-cell failure in this disease ( 146 , 171 ), but the molecule also has regulatory properties in normal physiology. Unlike the accelerating effects of BPA, four BPs analogues (BPAF, BPAP, TBBPA and TCBPA) showed inhibitory effects on hIAPP aggregation and decreased the membrane disruption capacity of hIAPP. Deposition of β-cell toxic misfolded human islet amyloid polypeptide (hIAPP), a hormone biosynthesized and secreted by the pancreatic β-cells, is a cardinal finding in type 2 diabetes mellitus (T2DM).

Islet Amyloid Polypeptide (IAPP), amylin, is a 37 amino acid polypeptide, that was originally isolated as the chief constituent of pancreatic islets from subjects with type 2 diabetes (T2DM) [1,2]. IAPP may serve as a novel pancreatic hormone to control carbohydrate metabolism. Features Islet amyloid polypeptide is a 37-amino acid peptide hormone, encoded by the homologous gene located on chromosome 12 (12p12.1). In type 2 diabetes, this peptide aggregates to form amyloid fibrils that are toxic to β-cells.
