Neurotoxicity of .BETA.-amyloid.

open access: yesFolia Pharmacologica Japonica, 2000
Recent observations on the neurotoxicity of beta-amyloid have been reviewed and possible roles of racemization of beta-amyloid are discussed. beta 1-40, beta 25-35 and D-Ser26 beta 25-35 (all HCl salt forms), but not commercially available beta 1-40 (TFA salt form), take the beta-structure within few hours in PBS, form fibrils, exert toxic effects on ...

Synapses, synaptic activity and intraneuronal Aβ in Alzheimer's disease

open access: yesFrontiers in Aging Neuroscience, 2010
β-amyloid peptide accumulation plays a central role in the pathogenesis of Alzheimer’s disease. Aberrant β-amyloid buildup in the brain has been shown to be present both in the extracellular space and within neurons.

Acyl peptide hydrolase degrades monomeric and oligomeric amyloid-beta peptide

open access: yesMolecular Neurodegeneration, 2009
Background The abnormal accumulation of amyloid-beta peptide is believed to cause malfunctioning of neurons in the Alzheimer's disease brain. Amyloid-beta exists in different assembly forms in the aging mammalian brain including monomers, oligomers, and ...

DHA supplemented in peptamen diet offers no advantage in pathways to amyloidosis: is it time to evaluate composite lipid diet? [PDF]

open access: yesPLoS ONE, 2011
Numerous reports have documented the beneficial effects of dietary docosahexaenoic acid (DHA) on beta-amyloid production and Alzheimer's disease (AD).

Molecules that Target beta‐Amyloid

open access: yesChemMedChem, 2007
AbstractThe devastating effects of Alzheimer’s and related amyloidogenic diseases have inspired the synthesis and evaluation of numerous ligands to understand the molecular mechanism of the aggregation of the beta‐amyloid peptide. Our review focuses on the current knowledge in this field with respect to molecules that have been demonstrated to interact

Plasma pyroglutamate‐modified amyloid beta differentiates amyloid pathology

open access: yesAlzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, 2020
Introduction Pyroglutamate‐modified amyloid β (AβpE3) could be a biomarker for Aβ plaque pathology in the brain. An ultra‐high‐sensitive assay is needed for detecting AβpE3‐40.

Medroxyprogesterone Acetate Impairs Amyloid Beta Degradation in a Matrix Metalloproteinase-9 Dependent Manner

open access: yesFrontiers in Aging Neuroscience, 2020
Despite the extensive use of hormonal methods as either contraception or menopausal hormone therapy (HT), there is very little known about the potential effects of these compounds on the cellular processes of the brain.

Accelerated Amyloid Beta Pathogenesis by Bacterial Amyloid FapC

open access: yesAdvanced Science, 2020
The gut–brain axis has attracted increasing attention in recent years, fueled by accumulating symptomatic, physiological, and pathological findings. In this study, the aggregation and toxicity of amyloid beta (Aβ), the pathogenic peptide associated with ...
