AU - Dear, Alexander J. AU - Meisl, Georg. AU - Šarić, Anđela The α-syn amyloid fibril structure shows two protofilaments intertwining along an approximate 2 1 screw axis into a left-handed helix. Each protofilament features a Greek key-like topology. Remarkably, five out of the six early-onset PD familial mutations are located at the dimer interface of the fibril (H50Q, G51D, and A53T/E) or involved in the stabilization of the protofilament (E46K). Amyloid fibril polymorphism. Amyloid fibril polymorphism describes the variations in fibril structures formed by a given polypeptide chain. Variations between sequence different polypeptide chains, such as Aβ(1‐40) and Aβ(1‐42), may not therefore classify, strictly speaking, as polymorphisms.

Amyloid fibrils are long fibrillar homopolymers of self-assembled proteins. They can be formed by essentially any polypeptide, but are of particular interest because of their occurrence in several incurable and debilitating human diseases, e.g. Alzheimer’s disease (AD). A central pathological event in AD is build-up of amyloid fibrils by the amyloid-β (Aβ) peptide. This thesis describes my

The protein solutions were then distributed into a series of cluster tubes and incubated at 37 °C. The amyloid fibril composition has important clinical implications, both regarding diag- nostic tests, phenotype of the disease, and on response to treatment since early onset ATTR Val30Met amyloidosis patients, who predominantly carry type B fibrils, display superior sur- However, structural details of misfolded Aβ(1-42) have remained elusive.

Amyloids are aggregates of proteins characterised by a fibrillar morphology of 7–13 nm in diameter, a β-sheet secondary structure (known as cross-β) and ability to be stained by particular dyes, such as Congo red. 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.

2021-04-07 · Amyloid plaques and neuroinflammation are hallmarks of Alzheimer’s disease. Fibrils, rope-like fibres, formed by amyloid-beta are the principal component of the amyloid plaques. Amyloid-beta can however assemble into multiple different fibril types, known as polymorphs, each of which has a distinctive molecular structure.
