Core Tip

Core tip: This study established a new immortalized mouse hepatic cell line through the transfection of the pRSV-T plasmid. SV40 T-antigen (SV40LT)-immortalized mouse hepatic cells had the same morphology and biological characteristics as primary mouse hepatic cells. SV40LT-immortalized mouse hepatic cells could be transfected with the pHBV1.3 plasmid, which caused the hepatitis B virus (HBV) genes to replicate in SV40LT-immortalized mouse hepatic cells. The expressions of hepatitis B surface antigen and hepatitis B c antigen, as well as the presence of HBV DNA replication intermediates, were observed in the pHBV1.3-transfected cells. This cell model will contribute to the research of HBV and the evaluation of anti-viral drugs in vivo.
