Amyloid pathology is absent in these mice, but they have impaired neurogenesis. Specifically, the survival of BrdU-labeled neural progenitor cells was impaired leading to fewer newborn neurons. This effect was specific to expression of the mutant PSEN1 in that the survival and differentiation of progenitors in mice overexpressing wild-type human PSEN1 were similar to nontransgenic mice (Wen et al., 2002).
Transgene of human PSEN1 with the P117L mutation driven by the neuron specific enolase (NSE) promoter.
