AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Selective lowering of Abeta42 levels (the 42-residue isoform of the amyloid-beta peptide) with small-molecule gamma-secretase modulators (GSMs), such as some non-steroidal anti-inflammatory drugs, is a promising therapeutic approach for Alzheimer's disease ...
Formation of amyloid-beta (A beta)(1-42) amyloid fibrils, a characteristic feature of Alzheimer's disease (AD), was monitored in situ through atomic force microscopy (AFM). Well-structured amyloid fibrils slowly formed in solution within 24 hours for which ...
Microglial cells aggregate around amyloid plaques in Alzheimer's disease, but, despite their therapeutic potential, various aspects of their reactive kinetics and role in plaque pathogenesis remain hypothetical. Through use of in vivo imaging and quantitat ...
Aggregation and fibril formation of amyloid-β (Aβ) peptides play a pivotal role in the pathogenesis of Alzheimer's disease (AD). Aβ peptides, principally comprising of 40 or 42 amino acid residues (Aβ40 and Aβ42), are produced by proteolytic processing of ...
The amyloid cascade hypothesis, supported by strong evidence from genetics, pathology and studies using animal models, implicates amyloid-beta (Abeta) oligomerization and fibrillogenesis as central causative events in the pathogenesis of Alzheimer's diseas ...
Aggregation and fibril formation of amyloid-beta (Abeta) peptides Abeta40 and Abeta42 are central events in the pathogenesis of Alzheimer disease. Previous studies have established the ratio of Abeta40 to Abeta42 as an important factor in determining the f ...

Recently, two large independent genome-wide association studies have provided compelling evidence that polymorphisms at the phosphatidylinositol-binding clathrin assembly protein (PICALM) locus are linked to Alzheimer’s disease (AD). At the cellular level, ...
Several amyloid-forming proteins are characterized by the presence of hydrophobic and highly amyloidogenic core sequences that play critical roles in the initiation and progression of amyloid fibril formation. Therefore targeting these sequences represents ...
Alzheimer's disease (AD) is the most common cause of dementia, and is characterized by memory loss and cognitive decline, as well as amyloid β (Aβ) accumulation, and progressive neurodegeneration. Cdk5 is a proline-directed serine/threonine kinase whose ac ...
The heat shock protein Hsp104 has been reported to possess the ability to modulate protein aggregation and toxicity and to "catalyze" the disaggregation and recovery of protein aggregates, including amyloid fibrils, in yeast, Escherichia coli, mammalian ce ...
