Figure 4. DAPT administration significantly reduces Aβ40 after SCI.
DAPT (a γ-secretase Inhibitor) and vehicle were administered orally (30mg/kg) twice a day for 3 days to sham and injured mice starting at 15 minutes after injury. Mice were sacrificed (n=4) on the next day after the last dose and Aβ40 ELISA was performed. There is no difference between the amount of Aβ present in sham vehicle- and DAPT-treated. However, the DAPT-treated injured mice have significantly (p value < 0.01) less Aβ than the vehicle-treated SCI mice.
