Aggregation dynamics of a 150 kDa Aβ42 oligomer: Insights from cryo electron microscopy and multimodal analysis.

ABSTRACT: Protein misfolding is a widespread phenomenon that can result in the formation of protein aggregates, which are markers of various disease states, including Alzheimer's disease (AD). In AD, amyloid beta (Aβ) peptides are key players in the disease's progression, particularly the 40- and 42- residue variants, Aβ40 and Aβ42. These peptides aggregate to form amyloid plaques and contribute to neuronal toxicity. Recent research has shifted attention from solely Aβ fibrils to also include Aβ protofibrils and oligomers as potentially critical pathogenic agents. Particularly, oligomers demonstrate more significant toxicity compared to other Aβ specie. Hence, there is an increased interest in studying the correlation between toxicity and their structure and aggregation pathway. The present study in
