Wnt-5aoccludes Aβ oligomer-induced depression of glutamatergic transmission in hippocampal neurons
(2010)
Abstract
Background
Soluble amyloid-β (Aβ;) oligomers have been recognized to be early and key intermediates in Alzheimer's disease (AD)-related synaptic dysfunction. Aβ ...
Direct Observations of Amyloid β Self-Assembly in Live Cells Provide Insights into Differences in the Kinetics of Aβ(1–40) and Aβ(1–42) Aggregation
(Cell Press, 2014-05)
Insight into how amyloid β (Aβ) aggregation occurs in vivo is vital for understanding the molecular pathways that underlie Alzheimer’s disease and requires new techniques that provide detailed kinetic and mechanistic ...
Envolvimento de reguladores traducionais e do sistema ubiquitina-proteassoma em modelos de toxicidade de oligômeros de Aβ

β-amyloid inhibits protein prenylation and induces cholesterol sequestration by impairing SREBP-2 cleavage
(Society for Neuroscience, 2012-05-09)
Accumulation of β-amyloid (Aβ) inside brain neurons is an early and crucial event in Alzheimer's disease (AD). Studies in brains of AD patients and mice models of AD suggested that cholesterol homeostasis is altered in ...
Intrahippocampal Inoculation of Aβ1–42 Peptide in Rat as a Model of Alzheimer’s Disease Identified MicroRNA-146a-5p as Blood Marker with Anti-Inflammatory Function in Astrocyte Cells
(MDPI, 2023)
Circulating microRNAs (miRNAs) have aroused a lot of interest as reliable blood diagnostic biomarkers of Alzheimer's disease (AD). Here, we investigated the panel of expressed blood miRNAs in response to aggregated ...
STAT3 neuronal como mediador de la toxicidad de los astrocitos estimulados con oligómeros del péptido β-amiloide
(2018)
El estrés oxidativo y la desregulación de la señalización de calcio son señales importantes en una variedad de enfermedades neurodegenerativas, incluyendo la enfermedad de Alzheimer (EA). El factor de transcripción STAT3 ...
Rol de las especies reactivas de oxígeno en la modificación de la red mitocondrial y en la disminución de la expresión de la isoforma 2 del receptor de ryanodina inducidos por los oligómeros del péptido Aβ en neuronas
(Universidad de Chile, 2015)
La enfermedad de Alzheimer (EA) es un desorden neurodegenerativo caracterizado por la pérdida progresiva de memoria. Los oligómeros solubles sinaptotóxicos del péptido β-amiloide (AβOs) son reconocidos como los agentes ...
Amyloid-B-Acetylcholinesterase complexes potentiate neurodegenerative changes induced by the AB peptide. Implications for the pathogenesis of Alzheimer's disease
(2010)
Abstract
The presence of amyloid-β (Aβ) deposits in selected brain regions is a hallmark of Alzheimer's disease (AD). The amyloid deposits have "chaperone molecules" which play critical roles in amyloid ...
