Fluvastatin prevents glutamate-induced blood-brain-barrier disruption in vitro.

2008

Abstract Glutamate is an important excitatory amino acid in the central nervous system. Under pathological conditions glutamate levels dramatically increase. Aim of the present study was to examine whether the HMG-CoA inhibitor fluvastatin prevents glutamate-induced blood-brain-barrier (BBB) disruption. Measurements of transendothelial electrical resistance (TEER) were performed to analyze BBB integrity in an in vitro co-culture model of brain endothelial and glial cells. Myosin light chain (MLC) phosphorylation was detected by immunohistochemistry, or using the in-cell western technique. Intracellular Ca 2+ and reactive oxygen species (ROS) levels were analyzed using the fluorescence dyes …

MK801 blocks hypoxic blood-brain-barrier disruption and leukocyte adhesion.

2008

The aim of the present study was to examine the signaling pathways of hypoxia followed by reoxygenation (H/R)-induced disruption of the blood-brain-barrier (BBB) in a co-culture of astrocytes and brain endothelial cells (BEC) in vitro. We analyzed the possible stabilizing effect of MK801, a highly selective N-methyl-d-aspartate receptor (NMDAR) antagonist, on BBB integrity. Levels of reactive oxygen species (ROS), glutamate (Glut) release and monocyte adhesion were measured under normoxia and H/R. BBB integrity was monitored measuring the trans-endothelial electrical resistance (TEER). TEER values dropped under H/R conditions which was abolished by MK801. Glut release from astrocytes, but n…
