Abstract
1. The present study was aimed at elucidating effects of transforming growth factor-β (TGF-β) on blood–brain barrier (BBB) functions with mouse brain capillary endothelial (MBEC4) cells.
2. The permeability coefficients of sodium fluorescein and Evans blue albumin for MBEC4 cells and the cellular accumulation of rhodamine 123 in MBEC4 cells were dose-dependently decreased after a 12-h exposure to TGF-β1 (0.01–10 ng/mL).
3. The present study demonstrates that TGF-β lowers the endothelial permeability and enhances the functional activity of P-gp, suggesting that cellular constituents producing TGF-β in the brain may keep the BBB functioning.
