“…Once stimulated, the endothelial cell undergoes a number of morphological changes, including increased surface expression of adhesion molecules, cytoskeletal reorganization, and activation of signaling pathways (5,17,37). A strong and repeatable correlation between induction of ICAM-1 and increased BBB permeability has been shown in a number of pathologies characterized by acute inflammation, including atherosclerosis, ischemia, human immunodeficiency virus encephalitis, and autoimmune disorders (4,19,38,47). Furthermore, loss of endothelial cell, tight junction proteins, occludin, and zonula occludens-1 was observed in cerebral vascular endothelium during neutrophil-induced BBB breakdown (1).…”
