In conclusion, our studies are consistent with the notion
that A-AChE complexes trigger some of the neurodegenerative
changes observed in AD brain, and that
AChE may potentiate not only the amyloid deposition in
vivo, but also the toxicity of the amyloid deposits. Finally,
recent studies obtained with a double-transgenic mice
that overexpress human AChE and APP are consistent
with the results presented here, in fact, double-APPAChE
transgenic mice showed amyloid plaques earlier
than those animals overexpressing APP alone
