Abstract

Recent structural studies show distinct morphologies for the fibrils of Aβ(1-42) and Aβ(1-40), which are believed not to co-fibrillize. We describe here a novel, structurally-uniform 1 : 1 mixed fibrillar species, which differs from both pure fibrils. It forms preferentially even when Aβ(1-42) : Aβ(1-40) peptides are mixed in a non-stoichiometric ratio.
