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).

Modification Details

Human wild-type PSEN1 driven by neuron-specific enolase (NSE).
