Ro5-4864 reduces hippocampal gliosis in 3xTgAD mice. A–J, Representative photomicrographs show GFAP (A–E) and IBA-1 (F–J) immunoreactivities in the hippocampus CA1 region of 7-month-old 3xTgAD mice in the sham + vehicle (A, F), GDX + vehicle (B, G), and GDX + Ro5-4864 (C, H) conditions; and 24-month-old 3xTgAD mice administered vehicle (D, I) and Ro5-4864 (E, J). K, GFAP immunoreactivity volume density values (±SEM) in the hippocampus CA1 region. L, IBA-1 immunoreactivity volume density values (±SEM) in the hippocampus CA1 region. #p < 0.001, compared with GDX + vehicle. *p < 0.001, compared with all other groups.
