Figure Lengend Snippet: Temporal expression of TLR2 in rat brain after DAI. (a) A coronal brain map showed the region where the TLR2 expression was observed in frontal cortex, corpus callosum (from brain midline to lateral ventricle, at bregma level −3), and internal capsule. (b) The expression of TLR2 in rat cortex, corpus callosum, and internal capsule was measured at 1 d, 3 d, and 7 d after DAI by immumohistochemical staining (scale bar = 100 μ m; n = 6). The bar graphs showed the statistical results for TLR2 expression ( ∗ p < 0.05, compared with control group; # p < 0.05, compared with DAI 1 d group; & p < 0.05, compared with DAI 3 d group). TLR2 positive cell levels were counted in 10 random fields (40x magnification). The relative increase in TLR2 level was assessed by densitometry (IOD). Data was presented as mean ± SD in three separate experiments.
