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 ...
Intrachain loop formation allows unfolded polypeptide chains to search for favorable interactions during protein folding. We applied triplet-triplet energy transfer between a xanthone moiety and naphthylalanine to directly measure loop formation in various ...
Described is a new class of small molecule inhibitors of amyloid beta protein (Abeta) aggregation, based on apomorphine. These molecules target the nucleation phase of Abeta self-assembly and interfere effectively with aggregation of Abeta 1-40 into amyloi ...
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 ...
Alzheimer's disease presents morphologically with senile plaques, primarily made of extracellular amyloid-beta (A beta) deposits, and neurofibrillary lesions, which consist of intracellular aggregates of hyper-phosphorylated tau protein. To study the in vi ...
Neurodegenerative diseases are more and more prevalent in our aging societies. A rapid overview of the etiology of many neurodegenerative diseases like Alzheimer, Parkinson, Huntington disease and amyotrophic lateral sclerosis suggests a tight link with mi ...
The key pathogenic event in the onset of Alzheimer's disease (AD) is the aggregation of beta-amyloid (Abeta) peptides into toxic aggregates. Molecules that interfere with this process might act as therapeutic agents for the treatment of AD. The amino acid ...
Alzheimer's disease is the most common form of neurodegenerative diseases in humans, characterized by the progressive accumulation and aggregation of amyloid-beta peptides (Abeta) in brain regions subserving memory and cognition. These 39-43 amino acids lo ...
The study of conformational transitions of peptides has obtained considerable attention recently because of their importance as a mol. key event in a variety of degenerative diseases. However, the study of peptide self-assembly into beta-sheets and amyloid ...
Reversal of amyloid formation through a controlled induced transformation from beta-sheet to sol. alpha-helix structures through the use of a switch element S could have an important consequences understanding the mechanisms of amyloid formation and cleara ...
