Background: Beside neurofibrillary tangles, amyloid plaques are the major histological hallmarks of Alzheimer's disease (AD) being composed of aggregated fibrils of beta-amyloid (A beta). During the underlying fibrillogenic pathway, starting from a surplus ...
Neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease and Huntington's disease share common mechanisms characterized by protein misfolding and aggregation, including formation of plaques or inclusion bodies. The rapid growing number o ...
Molecular probes for selective Identification of protein aggregates are important to advance our understanding of the molecular pathogenesis underlying cerebral amyloidoses. Here we report the chemical design of pentameric thiophene derivatives, denoted lu ...
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 ...
Soluble oligomers are potent toxins in many neurodegenerative diseases, but little is known about the structure of soluble oligomers and their structure-toxicity relationship. Here we prepared on-pathway oligomers of the 140-residue protein alpha-synuclein ...
The misfolding and aggregation of amyloid proteins has been associated with incurable diseases such as Alzheimer's or Parkinson's disease. In the specific case of Alzheimer's disease, recent studies have shown that cell toxicity is caused by solubl ...
Centrioles are evolutionarily conserved cylindrical cell organelleswith characteristic radial symmetry. Despite their considerable size (400 nm x 200 nm, in humans), genetic studies suggest that relatively few protein components are involved in their assem ...
We propose the application of a new label-free optical technique based on photonic nanostructures to real-time monitor the amyloid-beta 1-42 (Ab(1-42)) fibrillization, including the early stages of the aggregation process, which are related to the onset of ...
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, ...
In Alzheimer's disease, microglia cluster around beta-amyloid deposits, suggesting that these cells are important for amyloid plaque formation, maintenance and/or clearance. We crossed two distinct APP transgenic mouse strains with CD11b-HSVTK mice, in whi ...
