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.

We work on three exciting novel findings from our group.1. Brichos, a proprotein chaperone, blocks amyloid fibril formation of the amyloid beta-peptide (Abeta),

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. 22, 23 For example, amyloid fibril plaques might serve as reservoir of toxic gO Thioflavin T (ThT) is a commonly used probe to monitor in vitro amyloid fibril formation. Upon binding to amyloid fibrils, ThT gives a strong fluorescence signal at approximately 482 nm when excited at 450 nm . The mechanism of fluorescence enhancement upon binding to amyloid has been attributed to the rotational immobilization of the central C More generally, amyloid fibrils are associated with many different human diseases (Knowles et al., 2014), but how mutations alter the propensity of proteins to aggregate into amyloid fibrils is not well understood and there has been no large-scale analysis of the effects of mutations on the formation of any amyloid fibril. Amyloid β (Aβ) monomers are the smallest assembly units, and play an important role in most of the individual processes involved in amyloid fibril formation.

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.

When present during the phase of fibril polymerization, Congo red could inhibit fibril formation from some peptides.
