Early Divergence in Misfolding Pathways of Amyloid‐Beta Peptides [PDF]

ChemPhysChem, 2021
AbstractThe amyloid cascade hypothesis proposes that amyloid‐beta (Aβ) aggregation is the initial triggering event in Alzheimer's disease. Here, we utilize NMR spectroscopy and monitor the structural dynamics of two variants of Aβ, Aβ40 and Aβ42, as a function of temperature.

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

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

Engineering neprilysin activity and specificity to create a novel therapeutic for Alzheimer's disease. [PDF]

PLoS ONE, 2014
Neprilysin is a transmembrane zinc metallopeptidase that degrades a wide range of peptide substrates. It has received attention as a potential therapy for Alzheimer's disease due to its ability to degrade the peptide amyloid beta.

Western Agarose Native GeELution (WANGEL) with beta-amyloid and tau: Novel method to elute proteins or peptides using native agarose gels followed by Lumipulse assay

MethodsX, 2022
Alzheimer´s disease is characterized by hyperphosphorylated tau neurofibrillary tangles and beta-amyloid plaques. Both molecules can be easily measured in human fluids or tissue extracts by immunoassays.

The orphan drug dichloroacetate reduces amyloid beta-peptide production whilst promoting non-amyloidogenic proteolysis of the amyloid precursor protein.

PLoS ONE, 2022
The amyloid cascade hypothesis proposes that excessive accumulation of amyloid beta-peptides is the initiating event in Alzheimer's disease. These neurotoxic peptides are generated from the amyloid precursor protein via sequential cleavage by β- and γ ...

Recent advancements in nanomaterials-based electrochemiluminescent and photoelectrochemical techniques for the determination of beta-amyloid peptides

International Journal of Electrochemical Science, 2022
Beta-amyloid (Aβ) peptides have been considered as the core biomarkers for early diagnosis of Alzheimer's disease. Electrochemiluminescent (ECL) and photoelectrochemical (PEC) biosensors are two promising methods for disease diagnosis in view of their ...
