This transgenic mouse line expresses human APP with the Arctic mutation. Mutant human APP is expressed at about three-fold higher levels than endogenous murine APP. The mice develop an age-dependent progression of amyloid pathology that starts with intracellular Aβ accumulation. Around 7-9 months diffuse extracellular Aβ deposits develop in the subiculum and then spread to interconnected brain regions, such as the retrosplenial granular cortex, thalamus, and mammillary bodies by 12-15 months. Neuropathology is more severe in female mice than males, but males exhibit a similar spatiotemporal pattern of amyloid development (Rönnbäck et al., 2011).
