aFGF administration attenuates the loss of the TJ proteins claudin-5, occludin, and ZO-1. The AJ proteins p120-catenin and β-catenin improve BBB integrity following experimental TBI in mice. GAPDH was used as a loading control and for band density normalization. A. Representative western blots of the TJ proteins claudin-5, occludin, and ZO-1 and the AJ proteins p120-catenin and β-catenin. B. Quantified data regarding expression of the TJ proteins claudin-5, occludin, and ZO-1. C. Quantified data regarding expression of the AJ proteins p120-catenin and β-catenin. *P < 0.05 versus sham group. **P < 0.01 versus sham group. #P < 0.05 versus TBI group. Data are presented as the mean ± standard error of the mean. n = 6.
