Amyloid fibril structure of α-synuclein determined by cryo-electron microscopy. Cell Res. 28 , 897–903 (2018). CAS PubMed PubMed Central Google Scholar 2018-03-19 · Fig. 1: Amyloid fibril preparation and examples of amyloid fibril liquid crystal polymorphs. Fig. 2: Nematic and cholesteric phases of amyloid fibrils as observed by rotating the sample in the 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).
doi: 10.1073/pnas.1922741117. The in vitro amyloid fibril formation procedure is well established  and was initiated by diluting the protein solutions with an equal volume of 200 m m acetate buffer (pH 4.2)/100 m m KCl/1 m m EDTA. 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. Here we present the atomic model of an Aβ(1-42) amyloid fibril, from solid-state NMR (ssNMR) data. It displays triple parallel-β-sheet segments that differ from reported structures of Aβ(1-40) fibrils. The interplay between gO/CFs and amyloid fibrils has a high relevance for AD pathogenesis: GO/CFs, which are thought to represent the main toxic Aβ species, 8, 13, 21, 32 were shown to associate with amyloid fibril plaques in vivo, with potential consequences for the neurotoxic activities of both assembly types.

These partially (un)folded amyloidogenic conformations self-assemble into amyloid fibrils. During the amyloid fibril formation reactions of many proteins, the 9 Jan 2020 Further testing of the biopsy may be done to identify the type of amyloidosis by identifying the protein composition of the amyloid fibrils.
