WebApr 2, 2008 · The BBB is formed by the brain microvascular endothelial cells (BMEC), which are sealed by tight junctions (TJ). To identify genes that are differentially expressed in BMEC compared with peripheral endothelial cells, we constructed a subtractive cDNA library from porcine BMEC (pBMEC) and aortic endothelial cells (AOEC). Webcharacterized tight junction-associated protein (1, 20)] and occludin [a transmembrane tight junction protein in BMEC monolayer (17)], and cytoskeletal actin fila-ments. We report that VEGF treatment significantly reduced the amount of ZO-1 and occludin located at tight junctions and altered the distribution of actin filaments in the BMEC ...
