eEF-2 Phosphorylation Down-Regulates P-Glycoprotein Over-Expression in Rat Brain Microvessel Endothelial Cells

OBJECTIVE We investigated whether glutamate, NMDA receptors, and eukaryote elongation factor-2 kinase (eEF-2K)/eEF-2 regulate P-glycoprotein expression, and the effects of the eEF-2K inhibitor NH125 on the expression of P-glycoprotein in rat brain microvessel endothelial cells (RBMECs). METHODS Cortex was obtained from newborn Wistar rat brains. After surface vessels and meninges were removed...

Hyperbaric environment up-regulates CD15s expression on leukocytes, down-regulates CD77 expression on renal cells and up-regulates CD34 expression on pulmonary and cardiac cells in rat

Objective(s): The aim of this study was to estimate effects of hyperbaric (HB) treatment by determination of CD15s and CD11b leukocyte proinflammatory markers expression.  In addition, this study describes changes in CD77 and CD34 expression on rat endothelial cells in renal, pulmonary and cardiac tissue following exposure to hyperbaric pressure. Materials and Methods:Expression of CD11b and CD...

Brain Microvessel Endothelial Cells

Endothelial cells were prepared from bovine brain microvessels and grown in tissue culture. They contained factor VIIIivon Willebrand antigen, the most specific marker available for determination of the endothelial origin of cells in culture. The cultured cells formed complex tight junctions and contained few pinocytotic vessels. These properties are responsible for formation of the blood-brain...

Induction of P-glycoprotein by antiretroviral drugs in human brain microvessel endothelial cells.

The membrane-associated drug transporter P-glycoprotein (P-gp) plays an essential role in drug efflux from the brain. Induction of this protein at the blood-brain barrier (BBB) could further affect the ability of a drug to enter the brain. At present, P-gp induction mediated by antiretroviral drugs at the BBB has not been fully investigated. Since P-gp expression is regulated by ligand-activate...
