Actions biochimiques/physiologiques

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.
E T Jaikaran et al.
Biochimica et biophysica acta, 1537(3), 179-203 (2001-12-04)
Islet amyloid polypeptide (IAPP, amylin) is secreted from pancreatic islet beta-cells and converted to amyloid deposits in type 2 diabetes. Conversion from soluble monomer, IAPP 1-37, to beta-sheet fibrils involves changes in the molecular conformation, cellular biochemistry and diabetes-related factors.
Allam S Reddy et al.
Biophysical journal, 99(7), 2208-2216 (2010-10-07)
Patients with type II diabetes exhibit fibrillar deposits of human amylin protein in the pancreas. It has been proposed that amylin oligomers arising along the aggregation or fibril-formation pathways are important in the genesis of the disease. In a step

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
