Islet amyloid deposition is a characteristic feature of Type 2 diabetes. Accumulation of IAPP by abnormal intracellular peptide degradation in beta-cell could promote fibril formation. IAPP is present in high concentrations in beta-cell lysosomes. To determine if fibrils form in lysosomes and the pathway for the accumulation human islets were cultured under conditions of elevated production of insulin (11mM glucose) and inhibition of secretion (0.6mM diazoxide) and/or lysosoma...
