Evaluation of the effect of Nilvadipine after r-mTBI on microglial population (Iba1) at 22 days post-r-mTBI in CC, CA1 and cortex: (A–D) Representative images (20×) of the Iba1 staining in the CC revealed increased microglial activation after r-mTBI (p < 0.0001) and a reduction of Iba1 immunoreactivity by Nilvadipine (p < 0.001). No difference in Iba1 was detected for CA1 (A–D) and cortex (E–H). Quantitative analysis of Iba1 staining in three 100 μm2 fields of the CC (I), CA1 (J) and cortex (K) at 22 days post-injury confirms the injury-induced and Nilvadipine-induced changes in glial response in CC. Scale bars equal 50 μm. Data are presented as mean ± standard error of the mean; significance is calculated using one-way ANOVA. ***p < 0.001; ****p < 0.0001.
