Varenicline Ameliorates Learning and Memory Deficits in Amyloid β(25–35) Rat Model of Alzheimer’s Disease
Introduction: Alzheimer’s disease (AD) is a enfeeble neurodegenerative disorder characterized by increased β-amyloid (Aβ) deposition and neuronal dysfunction leading to impaired learning and recall. Among proposed risk factors, impaired cholinergic transmission is a main cause for incidence of disease. Methods: In the present study, effects of the intracerebroventricularly administration of an ...
متن کاملMethionine 35 oxidation reduces fibril assembly of the amyloid abeta-(1-42) peptide of Alzheimer's disease.
The major component of amyloid plaques in Alzheimer's disease (AD) is Abeta, a small peptide that has high propensity to assemble as aggregated beta-sheet structures. Using three well established techniques for studying amyloid structure, namely circular dichroism, thioflavin-T fluorescence, and atomic force microscopy, we demonstrate that oxidation of the Met-35 side chain to a methionine sulf...

متن کاملInhibition of toxicity and protofibril formation in the amyloid-beta peptide beta(25-35) using N-methylated derivatives.
Beta (25-35) is a fragment of beta-amyloid that retains its wild-type properties. N-methylated derivatives of beta(25-35) can block hydrogen bonding on the outer edge of the assembling amyloid, so preventing the aggregation and inhibiting the toxicity of the wild-type peptide. The effects are assayed by Congo Red and thioflavin T binding, electron microscopy and an MTT [3-(4,5-dimethylthiazol-2...
متن کاملAmyloid-β peptide promotes bacterial aging
The pathological hallmark of Alzheimer's disease is brain deposition of senile plaques composed predominantly of amyloid fibrils. These conformational structures, characteristic of many other human disorders, are formed mainly by the amyloid-β peptide Aβ42. This peptide, which is primarily disordered and soluble as an isolated monomer, can undergo an aggregation and fibrillation process that re...
