Abstract
Interastrocytic gap junctions in the blood-brain barrier of the experimental penumbra area were studied in the cat caudate nucleus 1 h after ischemia. Transmission electron microscopy and freeze-fracture studies revealed only slight changes in gap junctions between astrocytes, indicating that these junctions are very resistant to hypoxia.
摘要
在猫尾状核缺血1小时后，对实验性半暗带区域血脑屏障中的星形胶质细胞间缝隙连接进行了研究。透射电子显微镜和冷冻蚀刻研究显示，星形胶质细胞之间的缝隙连接仅有轻微变化，表明这些连接对缺氧具有很强的抵抗力。
