چکیده

Human islet amyloid polypeptide (hIAPP) deposit is the hallmark of type 2 diabetes pathology. Here, we report that apo-cyclen, attached to a specific hIAPP recognition motif (NYGAIL), captured copper ions and became proteolytically active. This cyclen-NYGAIL-copper complex was able to interfere with hIAPP aggregation and cleave hIAPP. These activities rescued INS-1 cells from hIAPP induced cytotoxicity.

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 ...

Copper-induced cytotoxicity: reactive oxygen species or islet amyloid polypeptide oligomer formation.

Copper enhances amyloid cytotoxicity and mediates human islet amyloid polypeptide (hIAPP) oligomerization; nickel, a redox inactive metal with similar protein binding affinity to copper, also mimics this effect, thereby demonstrating copper-mediated hIAPP cytotoxicity is due mainly to granular oligomer generation rather than ROS accumulation in type 2 diabetes.

Carvacrol and Thymol Attenuate Cytotoxicity Induced by Amyloid β25-35 Via Activating Protein Kinase C and Inhibiting Oxidative Stress in PC12 Cells

Background: Our previous findings indicated that carvacrol and thymol alleviate cognitive impairments caused by Aβ in rodent models of Alzheimer's disease (AD). In this study, the neuroprotective effects of carvacrol and thymol against Aβ25-35-induced cytotoxicity were evaluated, and the potential mechanisms were determined. Methods: PC12 cells were pretreated with Aβ25-35 for 2 h, followed by ...

Inhibition of human amylin fibril formation by insulin-mimetic vanadium complexes.

The toxicity of amyloid-forming proteins can be linked to many degenerative and systemic diseases. Human islet amyloid polypeptide (hIAPP, amylin) has been associated with type II diabetes. Methods for efficient inhibition of amyloid fibril formation are highly clinically important. This study demonstrated the significant inhibitory effects of six vanadium complexes on hIAPP aggregation. Vanadi...
