Abstract
1. The present study aimed at elucidating the effect of nitric oxide (NO) on blood-brain barrier (BBB) function with mouse brain capillary endothelial (MBEC4) cells.2. Histamine (20-100 microM) evoked NO production (1.6-7 microM) in MBEC4 cells in a dose-dependent manner.3. The permeability coefficient of sodium fluorescein for MBEC4 cells and the cellular accumulation of rhodamine 123 in MBEC4 cells were increased dose-dependently by the addition of NO solutions (14 and 28 microM) every 10 min during a 30-min period.4. The present study demonstrated that NO increased the permeability and inhibited the P-glycoprotein efflux pump of brain capillary endothelial cells, suggesting that NO plays an inhibitory role in the dynamic regulation of the BBB function.Entities:
