Figure 6. Levels of GFAP in mouse brains. (A) Representative immunofluorescence staining of GFAP, a marker of astrocytes. (B) Representative bands of GFAP in brain tissues detected by Western blots. (C) GFAP significantly increased in AD mice and AD-TLR2KO mice compared with WT and TLR2 mice, respectively (#: AD vs. WT, p<0.05; +: AD-TLR2KO vs. WT, p<0.05). Moreover, the level of GFAP in AD-TLR2KO mice was significantly higher than that in AD mice (*: AD-TLR2KO vs. AD, p<0.05). (n= 6 / group).
