Val97Leu mutant presenilin-1 induces tau hyperphosphorylation and spatial memory deficit in mice and the underlying mechanisms.

Abstract excerpt

Although the pathological role of presenilin-1 mutation in early onset familial Alzheimer's disease has been widely studied, few focused on how the presenilin-1 mutations result in memory impairment and tau hyperphosphorylation. In the present study, we expressed human Val97Leu mutant presenilin-1, which is reported in Chinese pedigrees by our group, in transgenic mice and found that the mutant presenilin-1...
