A prominent current hypothesis is that impaired metal ion homeostasis may contribute to Alzheimer's disease (AD). We elucidate the interaction of Cu2+ with wild‐type (WT) Aβ1–40 and the genetic variants A2T and A2V which display increasing pathogenicity as A2T<WT<A2V. Cu2+ significantly extends the lag phase in aggregation kinetics, in particular for the pathogenic A2V variant. Additionally,...
The apolipoprotein E4 (apoE4) genotype is a major risk factor for Alzheimer's disease (AD); however, the mechanism is unknown. We previously demonstrated that apoE isoforms differentially modulated neurite outgrowth in embryonic neurons and in neuronal cell lines. ApoE3 increased neurite outgrowth whereas apoE4 decreased outgrowth, suggesting that apoE4 may directly affect neurons in the brain. In...
