Iba1 immunohistochemistry. Mice were sacrificed and brain sections were immunohistochemically stained for the microglial marker Iba1. (A, C) Representative microphotographs show Iba1 immuno-stained microglia of the mouse hippocampus. (B, D) The number of Iba1 antibody-stained microglia was normalized in the corresponding same area, as the ratio (in percentage) of the Veh+Veh are shown. Original magnifications are 200× (Scale bar=150 μm) and 400× (Scale bar=50 μm). Data shown are expressed as mean±SEM. n=6. ^*P<0.05, ^**P<0.01 vs LPS+Veh.
