英文摘要
Hepatitis B virus infection is a serious health problem worldwide. As the hepatitis B virus infects only humans and chimpanzees, establishment of reliable culture system is necessary to study this important pathogen. We cloned a fu11 length genotype C clone of the hepatitis B virus from a patient with a very mild hepatitis. About one and half genome was cloned into a plasmid vector. The 1.4 length clone was transfected to a HepG2 cell line. The resultant cell line produced HBs antigen, HBe antigen and HBV DNA to a supernatant. The titer of HBV DNA was 10^6-10^7 copy/ml. The production of the HBV DNA was reduced by incubation of lamivudine and interferons. The clones should be useful to further develop anti-hepatitis B virus agents and study biological properties of the hepatitis B virus.
