摘要

The Arctic mutation within the amyloid-β (Aβ) peptide causes Alzheimer disease. In vitro, Arctic-mutant Aβ forms (proto)fibrils more effectively than wild-type Aβ. We generated transgenic mouse lines expressing Arctic-mutant human amyloid precursor proteins (hAPP). Amyloid plaques formed faster and were more extensive in Arctic mice than in hAPP mice expressing wild-type Aβ, even though Arctic mice had lower Aβ1-42/1-40 ratios. Thus, the Arctic mutation is highly amyloidogenic in vivo.
