Selection for nonamyloidogenic mutants of islet amyloid polypeptide (IAPP) identifies an extended region for amyloidogenicity.
The aggregation of the 37-residue protein, islet amyloid polypeptide (IAPP), as either insoluble amyloid or as small oligomers, appears to play a direct role in the death of pancreatic beta-islet cells in type II diabetes. While IAPP has been known to be the primary component of type II diabetes amyloid, the molecular interactions responsible for this aggregation have not been identified. To id...
متن کاملcontribution of setting to the study of characters and the main idea in e. brontes: wuthering heights and t. hardys: return of the native.
this thesis aims to adduce an unmitigated and comprehensive explication concerning the relationship of three significant elements of fiction: setting, chracter and theme. my research is basically placed on two outstanding novels of the 19th century: emily brontes wuthering heights and thomas hardys return of the native. my endeavour lies in studying the correlation among the three above-mention...
15 صفحه اولIslet 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 کاملIslet 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 کاملGenetic background determines the extent of islet amyloid formation in human islet amyloid polypeptide transgenic mice.
Genetic background is important in determining susceptibility to metabolic abnormalities such as insulin resistance and beta-cell dysfunction. Islet amyloid is associated with reduced beta-cell mass and function and develops in the majority of our C57BL/6J x DBA/2J (F(1)) male human islet amyloid polypeptide (hIAPP) transgenic mice after 1 yr of increased fat feeding. To determine the relative ...
