Abstract
Hypoxia and post-hypoxic reoxygenation induces disruption of the blood–brain barrier (BBB). Alterations of the BBB function after hypoxia/reoxygenation (H/R) injury remain unclear. Cyclosporin A (CsA), a potent immunosuppressant, induces neurotoxic effects by entering the brain, although the transport of CsA across the BBB is restricted by P-glycoprotein (P-gp), a multidrug efflux pump, and tight junctions of the brain capillary endothelial cells. The aim of this study was to evaluate whether the BBB after H/R damage is vulnerable to CsA-induced BBB dysfunction. We attempted to establish a pathophysiological BBB model with immortalized mouse brain capillary endothelial (MBEC4) cells. The effects of CsA on permeability and P-gp activity of the MBEC4 cells were then examined. Exposure to hypoxia for 4 h and reoxygenation for 1 h (H/R (4 h/1 h)) produced a significant decrease in P-gp function of MBEC4 cells, without changing cell viability and permeability for sodium fluorescein and Evan’s blue-albumin at 7 days after H/R (4 h/1 h). CsA-induced hyperpermeability and P-gp dysfunction in MBEC4 monolayers at 7 days after H/R (4 h/1 h) were exacerbated. The possibility that CsA penetrates the BBB with incomplete functions in the vicinity of cerebral infarcts to induce neurotoxicity has to be considered.
