Acciones bioquímicas o fisiológicas

Islet amyloid polypeptide (IAPP) is a hormone coexpressed with insulin by pancreatic β-cells. IAPP is used to study the mechanisms of amyloid deposition and its role in molecular misfolding processes expecially in conditions such as diabetes type II.

Human islet amyloid polypeptide is a hormone coexpressed with insulin by pancreatic beta-cells. For reasons not clearly understood, hIAPP aggregates in type II diabetics to form oligomers that interfere with beta-cell function, eventually leading to the loss of insulin production.

The role of islet amyloidosis in the onset and progression of Type 2 diabetes remains obscure. Islet amyloid polypeptide is a 37 amino-acid, beta-cell peptide which is co-stored and co-released with insulin. Human islet amyloid polypeptide refolds to a beta-conformation

Amyloid deposits localized to the islets of Langerhans are typical of non-insulin-dependent human diabetes mellitus and of diabetes mellitus in adult cats. Amyloid deposits also commonly occur in insulin-producing pancreatic tumors. We have purified a major protein--insulinoma or islet amyloid
G J Cooper et al.
Proceedings of the National Academy of Sciences of the United States of America, 84(23), 8628-8632 (1987-12-01)
Deposition of amyloid in pancreatic islets is a common feature in human type 2 diabetic subjects but because of its insolubility and low tissue concentrations, the structure of its monomer has not been determined. We describe a peptide, of calculated
