Figure 2From: Green tea polyphenols alleviate early BBB damage during experimental focal cerebral ischemia through regulating tight junctions and PKCalpha signaling The postischemic ultra structure of TJ after GTPs administration was examined by TEM. Representative graphs of the following groups: A1–A4, the vehicle group at 0, 30, 60, and 120 min after ischemia; B1–B4, the GTPs group at 0, 30, 60, and 120 min after ischemia, respectively. Graphs (A1, A2, B1, B2, B3, B4) show that TJ barrier was intact. Graphs (A3, A4) display an increase in the gap at TJ. Arrows show TJ. Scale bars = 400 nm.Back to article page
