Self-folding and aggregation of amyloid nanofibrils.
Amyloids are highly organized protein filaments, rich in β-sheet secondary structures that self-assemble to form dense plaques in brain tissues affected by severe neurodegenerative disorders (e.g. Alzheimer's Disease). Identified as natural functional materials in bacteria, in addition to their remarkable mechanical properties, amyloids have also been proposed as a platform for novel biomateria...
متن کاملStability and cytotoxicity of crystallin amyloid nanofibrils.
Previous work has identified crystallin proteins extracted from fish eye lenses as a cheap and readily available source for the self-assembly of amyloid nanofibrils. However, before exploring potential applications, the biophysical aspects and safety of this bionanomaterial need to be assessed so as to ensure that it can be effectively and safely used. In this study, crude crystallin amyloid fi...
متن کاملSynthesis and biological assessment of 2-hydroxyiminoethanones as anti-inflammatory and β-amyloid aggregation inhibitors
Alzheimer’s disease (AD) is a neuroinflammatory based pathologic state in which β-amyloid aggregates are a major devastating agents. In this study, a series of 2-hydroxyiminoethanones were synthesized and evaluated as anti-inflammatory in carrageenan and formalin tests and inhibitors of β-amyloid aggregation. Compounds 1-10b were synthesized through a two-step reaction. Results: Compounds 1-5b ...
متن کاملProteome folding and aggregation.
The description of protein folding at the proteome level requires further principles in addition to those that govern this phenomenon for individual molecules. An important aspect of the increased complexity of the folding process in the cellular environment is that proteins tend to be metastable against aggregation, as they are often expressed at levels at which they are poorly soluble. The ma...
