Summary

These transgenic mice express a chimeric mouse/human APP carrying the Swedish mutation under the control of the mouse prion protein promoter. This line, E1-2, was generated in parallel with line C3-3 which also expresses APP with the Swedish mutation. Mice that are hemizygous for the transgene are viable and fertile and express mutant human APP at levels about three-fold higher than endogenous murine APP. They develop elevated Aβ at advanced age, with low levels at 6-14 months and higher levels at 24-26 months. On a noncongenic background some deficits in cognitive performance were observed in aging animals, but these deficits largely disappeared after the mice were back-crossed and became congenic (Savonenko et al., 2003).

This model was previously available through The Jackson Lab as Stock# 006005.

Modification Details

Transgene is a chimeric mouse/human APP (isoform 695) with a "humanized" Aβ domain carrying the Swedish mutation under the control of the mouse prion protein promoter.
