Aβ(1–42) fibril structure illuminates self-recognition and replication of amyloid in Alzheimer's disease

Aβ(1–42) is the most pathogenic amyloid-β species in Alzheimer's disease (AD). The solid-state NMR–based atomic model of an Aβ(1–42) fibril elucidates the mechanism of fibril formation and propagation in AD and other amyloid diseases.
