These mice express wild-type human PSEN1. Compared with mice expressing similar levels of human PSEN1 with the P117L mutation (i.e. PSEN1(P117L), expression of wild-type PSEN1 was associated with increased survival and differentiation of neural progenitor cells in the hippocampus, leading to the generation of more immature granule cells (Wen et al., 2002).
