BACE1 activity impairs neuronal glucose oxidation:rescue by beta-hydroxybutyrate and lipoic acid [PDF]

, 2015
Glucose hypometabolism and impaired mitochondrial function in neurons have been suggested to play early and perhaps causative roles in Alzheimer's disease (AD) pathogenesis. Activity of the aspartic acid protease, beta-site amyloid precursor protein (APP)

Targeting signaling pathways in neurodegenerative diseases: Quercetin's cellular and molecular mechanisms for neuroprotection

Animal Models and Experimental Medicine, EarlyView.
Quercetin regulates signaling pathways in neurodegenerative diseases, including NF‐κB, sirtuins, and PI3K/Akt. Studies show quercetin improves symptoms and pathology in neurodegenerative models. The study aims to incorporate laboratory research into practical medical treatment, focusing on quercetin's neuroprotective effects and optimal dosage ...

Intracellular pH regulates amyloid precursor protein intracellular domain accumulation

Neurobiology of Disease, 2007
The amyloid precursor protein (APP) metabolism is central to pathogenesis of Alzheimer’s disease (AD). Parenchymal amyloid deposits, a neuropathological hallmark of AD, are composed of amyloid-beta peptides (Abeta).

Krüppel‐like factor 4 transcription factor in blood–brain barrier endothelial cells: A potential role in Alzheimer's disease

Animal Models and Experimental Medicine, EarlyView.
KLF4 (Krüppel‐like factor 4) plays a protective role in blood–brain barrier (BBB). KLF4 plays an ambiguous role in the central nervous system. KLF4 in the BBB endothelial cells could be a potential target for Alzheimer's disease. Abstract Alzheimer's disease is the most prevalent chronic neurodegenerative disorder worldwide, with no sufficient cure ...

A guide to selecting high-performing antibodies for amyloid-beta precursor protein for use in Western Blot, immunoprecipitation and immunofluorescence [version 2; peer review: 2 approved, 1 approved with reservations]

F1000Research
The amyloid-beta precursor protein is a transmembrane protein expressed in many tissues and highly concentrated in the brain. The protein is of significant interest due to its involvement in the generation of amyloidogenic β-amyloid peptides, prone to ...

The Budapest Amyloid Predictor and its Applications [PDF]

arXiv, 2020
The amyloid state of proteins is widely studied with relevancy in neurology, biochemistry, and biotechnology. In contrast with amorphous aggregation, the amyloid state has a well-defined structure, consisting of parallel and anti-parallel $\beta$-sheets in a periodically repeated formation.

Amyloid proteotoxicity initiates an inflammatory response blocked by cannabinoids. [PDF]

, 2016
The beta amyloid (Aβ) and other aggregating proteins in the brain increase with age and are frequently found within neurons. The mechanistic relationship between intracellular amyloid, aging and neurodegeneration is not, however, well understood.

Vitamin B12 Levels Association with Functional and Structural Biomarkers of Central Nervous System Injury in Older Adults

Annals of Neurology, EarlyView.
At low levels of B12, specifically when bound to transcobalamin for cellular uptake, evidence of slower conductivity in the brain could point toward impaired myelin. At high levels of B12, specifically when bound to the biologically inert transport protein haptocorrin, biomarkers of neurodegeneration appear in the serum, indicating neuroaxonal injury ...

Atomic-resolution structures of prion AGAAAAGA amyloid fibrils [PDF]

Published in [Amyloids: Composition, Functions and Pathology, Editors Irene P. Halcheck and Nancy R. Vernon, NOVA Science Publishers, Hauppauge, N.Y., March 1st 2012, ISBN 978-1-62100-538-4, hardcover], Chapter 10, pp.177-186, 2011
To the best of the author's knowledge, there is little structural data available on the AGAAAAGA palindrome in the hydrophobic region (113-120) of prion proteins due to the unstable, noncrystalline and insoluble nature of the amyloid fibril, although many experimental studies have shown that this region has amyloid fibril forming properties and plays ...
