Nanopore analysis of amyloid fibrils formed by lysozyme aggregation.
The measurement of single particle size distributions of amyloid fibrils is crucial for determining mechanisms of growth and toxicity. Nanopore sensing is an attractive solution for this problem since it gives information on aggregates' shapes with relatively high throughput for a single particle technology. In this paper we study the translocation of lysozyme fibrils through quartz glass nanop...
متن کاملAnalysis of Core Region from Egg White Lysozyme Forming Amyloid Fibrils
Some of the lysozyme mutants in humans cause systemic amyloidosis. Hen egg white lysozyme (HEWL) has been well studied as a model protein of amyloid fibrils formation. We previously identified an amyloid core region consisting of nine amino acids (designated as the K peptide), which is present at 54-62 in HEWL. The K peptide, with tryptophan at its C- terminus, has the ability of self-aggregati...
متن کاملIdentification of the core structure of lysozyme amyloid fibrils by proteolysis.
Human lysozyme variants form amyloid fibrils in individuals suffering from a familial non-neuropathic systemic amyloidosis. In vitro, wild-type human and hen lysozyme, and the amyloidogenic mutants can be induced to form amyloid fibrils when incubated under appropriate conditions. In this study, fibrils of wild-type human lysozyme formed at low pH have been analyzed by a combination of limited ...
متن کاملAmyloid seeds formed by cellular uptake, concentration, and aggregation of the amyloid-beta peptide.
One of the neuropathological hallmarks of Alzheimer's disease (AD) is the amyloid plaque, primarily composed of aggregated amyloid-beta (Abeta) peptide. In vitro, Abeta(1-42), the major alloform of Abeta found in plaques, self-assembles into fibrils at micromolar concentrations and acidic pH. Such conditions do not exist in the extracellular fluid of the brain where the pH is neutral and Abeta ...
متن کاملInhibition of Amyloid Fibrils Formation from Hen Egg White Lysozyme by Satureia Hortensis Extract and its Effect on Learning and Spatial Memory of Rats
Background & Aims: Alzheimer's disease is a neurodegenerative disorder characterized by the abnormal aggregation of amyloid-β plaques in the brain. Although several studies have been done for finding effective medicines in the treatment of this disease, a drug that inhibits amyloid β aggregation and ameliorates the disorder has not been approved so far. One important therapeutic approach is use...
