Abstract:
Objective To investigate the function of chemokine receptor 5(CCR5)in human brain microvascular endothelial cells(HBMEC)during T lymphocytes transendothelial migration induced by amyloid beta(Aβ).Methods The in vitro model of blood-brain barrier was established with cultured HBMEC monolayer.The ability of T lymphocytes transendothelial migration induced by Aβ was analyzed by Transwell and Millicell-ERS endothelia volt-ohmmeter.Results Aβ could promote T lymphocytes to migrate through the HBMEC monolayer.Over-expression of CCR5 in HBMEC promoted T lymphocytes to migrate through HBMEC monolayer.Expression of CCR5 mutant in HBMEC inhibited the transendothelial migration of T lymphocytes.Conclusion CCR5 of HBMEC is involved in T lymphocytes transendothelial migration induced by Aβ.
