    ..DAPT attenuated the toxic effect of EW or glutamate on HT22 cells. These results suggest that PS1 expression is triggered by glutamate through p38?, contributing to the excitotoxic stimulus of EW. ..

    ..Our data raise the possibility that PS1 may prevent development of AD pathology by activating the PI3K/Akt signaling pathway. In contrast, FAD mutations may promote AD pathology by inhibiting this pathway. ..

J Neurochem. 2006;96:1322-35 pubmed
