TBI led to long-term activation of microglia in the brain. (A) Representative fluorescence images of cortical and hippocampal (CA1, CA3, and DG) tissues from C57BL/6 and C57BL/6 TBI group mice immunostained for IBA-1 (in red) and subjected to nuclear staining with DAPI (in blue). (B) The fluorescence intensity of IBA-1 in the cortex and in the hippocampus (CA1, CA3, and DG). The error bars represent the SEM (n = 8/group). ns, non-significant; *p < 0.05; **p < 0.01; ***p < 0.001.
