Here, we report the high-resolution cryo-EM structures of Aβ filaments from the frontal cortex of a previously described case (AβPParc1) with the Arctic mutation. Most filaments consist of two pairs of non-identical protofilaments that comprise residues V12-V40 (human Arctic fold A) and E11-G37 (human Arctic fold B). They have a substructure (residues F20-G37) in common with the folds of type I and type II Aβ42. When compared to the structures of wild-type Aβ42 filaments, there are subtle conformational changes in the human Arctic folds, because of the lack of a side chain at G22, which may strengthen hydrogen bonding between mutant Aβ molecules and promote filament formation. A minority of Aβ42 filaments of type II was also present, as were tau paired helical filaments. In addition, we report the cryo-EM structures of Aβ filaments with the Arctic mutation from mouse knock-in line App. Most filaments are made of two identical mutant protofilaments that extend from D1 to G37 (App murine Arctic fold). In a minority of filaments, two dimeric folds pack against each other in an anti-parallel fashion. The App murine Arctic fold differs from the human Arctic folds, but shares some substructure. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
