Research Abstract

Our group demonstrated that N-cadherin expression facilitates cis-dimerization of APP. Moreover, N-cadherin expression led to increased production of Abeta as well as soluble APP beta, indicating that beta secretase mediated cleavage of APP is enhanced. Then we investigated whether copper alters the state of APP dimerization and how it affects APP metabolism. We demonstrated that copper enhanced APP dimerization and increased extracellular release of Abeta. Taken together, our results suggest that modulation of APP dimerization state could be one of mechanisms, which alters Abeta production.
