Thioflavin T (ThT) is a reagent known to become strongly fluorescent upon binding to amyloid fibrils. Here, we show that, by monitoring ThT fluorescence with total internal reflection fluorescenc … 2021-02-08 2019-03-05 Amyloid Fibril Formation by Aβ 16-22, a Seven-Residue Fragment of the Alzheimer's β-Amyloid Peptide, and Structural Characterization by Solid State NMR† John J. Balbach, Yoshitaka Ishii, Oleg N. Antzutkin, Richard D. Leapman, Nancy W. Rizzo, Fred Dyda, Jennifer Reed, and ; Robert Tycko 2018-03-19 2020-09-11 2021-02-01 In addition, the Alzheimer's plaque protein Aβ has been shown to undergo reversible amyloid fibril formation to a position of dynamic equilibrium such that reaction thermodynamics can be quantified. Studies of these well-behaved amyloid systems are allowing us to peer more deeply into the process and products of off-pathway misfolding and aggregation. However, structural details of misfolded Aβ(1-42) have remained elusive. Here we present the atomic model of an Aβ(1-42) amyloid fibril, from solid-state NMR (ssNMR) data.

Depending on the protein making up the fibrils, amyloid structures can accumulate at different sites in the body, including the brain, joints and pancreas. The amyloid fibrils are composed of the amyloid-β peptide (Aβ), a 39–43 amino acid residue peptide produced by cleavage from a larger amyloid precursor protein, APP. The Aβ peptide is known to be present in unaffected individuals and is thought to have a normal physiological role. An amyloid fibril protein is a protein that is deposited as insoluble fibrils, mainly in the extracellular spaces of organs and tissues as a result of sequential changes in protein folding that result in a condition known as amyloidosis. Accumulation of phosphorylated α-syn fibrils in Lewy bodies and Lewy neurites is the histological hallmark of these diseases.

In the human body, amyloids have been linked to the development of various diseases. Amyloid fibrils are thread-like protein aggregates that are insoluble and resistant to protease activity.

Here, we determin … Amyloids are implicated in neurodegenerative diseases. Fibrillar aggregates of the amyloid-β protein (Aβ) are the main component of the senile plaques found in brains of Alzheimer’s disease Identification of regions in the protein chains that form the backbone of amyloid fibril is a direction in the investigation of amyloid formation. Amyloid fibrils can also possess very high kinetic and thermodynamic stabilities, often exceeding those of the functional folded states of proteins (6), as well as a greater resistance to degradation by chemical or biological means (7). Amyloid fibrils are large and non-crystalline, which makes them difficult to study using the structural techniques developed for soluble proteins. So although there have been some important insights, the detailed molecular structures of amyloid fibrils from diseased tissue have remained out of reach.
