Fig 4. Memantine inhibits I1 PP2A-induced tau hyperphosphorylation.

Fig 4

A, B) Western blots showed increase in abnormal hyperphosphorylation of tau in AAV1-I1 PP2A rats. Quantitative analysis of the blots of hyperphosphorylated tau normalized with total tau showed significant increase in tau hyperphosphorylation at several sites studied and memantine was found to reverse this change. *P<0.05, **P<0.01 AAV1-I1 PP2A vs. AAV1-GFP rats; ΔP<0.05, ΔΔP<0.01 AAV1-I1 PP2A-memantine vs. AAV1-I1 PP2A-vehicle.
