Islet Amyloid Polypeptide is not a Target Antigen for CD8+ T-Cells in Type 2 Diabetes
Background: Type 2 diabetes (T2D) is a chronic metabolic disorder in which beta-cells are destroyed. The islet amyloid polypeptide (IAPP) produced by beta-cells has been reported to influence beta-cell destruction. Objective: To evaluate if IAPP can act as an autoantigen and therefore, to see if CD8 + T-cells specific for this protein might be present in T2D patients. Methods: Peripheral blood ...
متن کاملIslet amyloid polypeptide, islet amyloid, and diabetes mellitus.
Islet amyloid polypeptide (IAPP, or amylin) is one of the major secretory products of β-cells of the pancreatic islets of Langerhans. It is a regulatory peptide with putative function both locally in the islets, where it inhibits insulin and glucagon secretion, and at distant targets. It has binding sites in the brain, possibly contributing also to satiety regulation and inhibits gastric emptyi...
متن کاملRapid Publications Sequence of a cDNA Encoding Syrian Hamster Preproinsulin GRAEME I. BELL AND RAY SANCHEZ-PESCADOR
A complementary DNA (cDNA) library was prepared from messenger RNA (mRNA) isolated from Syrian hamster islets. Bacterial colonies containing hamster preproinsulin cDNA were identified by cross-hybridization with the human preproinsulin gene. The sequences of two of these established the complete sequence of Syrian hamster preproinsulin mRNA and predicted the sequence of the protein. Hamster pre...
متن کاملHuman islet amyloid polypeptide monomers form ordered beta-hairpins: a possible direct amyloidogenic precursor.
Oligomerization of human islet amyloid polypeptide (IAPP) has been increasingly considered a pathogenic process in type II diabetes. Here structural features of the IAPP monomer have been probed using a combination of ion mobility mass spectrometry (IMS-MS) and all-atom replica exchange molecular dynamics (REMD) simulations. Three distinct conformational families of human IAPP monomer are obser...
متن کاملIslet Amyloid Polypeptide: Structure, Function, and Pathophysiology
The hormone islet amyloid polypeptide (IAPP, or amylin) plays a role in glucose homeostasis but aggregates to form islet amyloid in type-2 diabetes. Islet amyloid formation contributes to β-cell dysfunction and death in the disease and to the failure of islet transplants. Recent work suggests a role for IAPP aggregation in cardiovascular complications of type-2 diabetes and hints at a possible ...
