Objective To investigate the effect of transfection of human liver cancer HepG2215 cells with Tollip on secretions of HBsAg and HBeAg as well as the relevant mechanism,and to search a novel target for therapy of hepatitis B.Methods Recombinant plasmid pCMV-HA-Tollip with a HA tag was digested with EcoRⅠ and KpnⅠ,and transfected to HepG2215 cells in mediation of LipofectamineTM 2000.HepG2215 cells were divided into liposome control,empty plasmid control,empty plasmid + pCMV-HA-Tollip and pCMV-HA-Tollip group...
