Abnormalities in the BSCB in PTS. Typical appearance of an occluding tight junction (black arrowhead) between capillary endothelial cells (EC), in the spinal cord of a healthy rat (a). Examples of abnormal capillaries in the rat spinal cord with PTS. The typical tight junctions between endothelial cells are not visible, and instead the intercellular junction is characterized by local swelling and dilation (black arrows). The intra- and extra-luminal spaces appear to be in continuity (b). L, lumen. Magnification: ×46,000 (a), ×64,000 (b). Scale bars: 0.2  µm (a), 0.1  µm (b)
