The expression of Claudin-5 and Occludin in penumbra at different time points after MCAO. Expression levels of claudin-5 at 8, 12 and 120 h after ischemia and of occludin at 8, 12, 24, and 120 h after were significantly reduced compared to the sham group. Data represent mean ± SEM, n = 6. *p < 0.05, **p < 0.01 vs. sham group
