Here, we report the cryo–electron microscopy (cryo-EM) structures of Aβ42 filaments from human brains. Two structurally related S-shaped protofilament folds give rise to two types of filaments. Type I filaments were found mostly in the brains of individuals with sporadic Alzheimer’s disease, and type II filaments were found in individuals with familial Alzheimer’s disease and other conditions. The structures of Aβ42 filaments from the brain differ from those of filaments assembled in vitro. By contrast, in knock-in mice, Aβ42 deposits were made of type II filaments. Knowledge of Aβ42 filament structures from human brains may lead to the development of inhibitors of assembly and improved imaging agents. 履歴 登録 2021年11月1日 - ヘッダ(付随情報) 公開 2021年11月24日 - マップ公開 2021年11月24日 - 更新 2025年7月2日 - 現状 2025年7月2日 処理サイト : PDBe / 状態 : 公開
