Figure 3. Microglia are less reactive in Gfap+/R236H mice without Nrf2.

Figure 3

(A) Compared to wild-type mice, Gfap mutant mice show elevated Iba1 immunoreactivity in hippocampus either with or without Nrf2. (B) Western analysis of hippocampal protein shows reduced Iba1 expression in Gfap+/R236H/Nrf2−/− compared with Gfap+/R236H/Nrf2+/+ mice (8 wks), although levels remain elevated above wild-type (**p<0.01, unpaired t-test comparing Gfap+/R236H/Nrf2+/+ with Gfap+/R236H/Nrf2−/− mice, n = 4). Lanes 5 and 6 for Nrf2−/− samples are from a different region of the same gel as lanes 1–4 (Nrf2+/+ samples).
