德国海德尔堡大学的研究人员利用乙型肝炎病毒（ＨＢＶ）或嗜肝ＤＮＡ病毒感染肝细胞的能力，将其用作载体，在肝炎动物模型中传递干扰素（ＩＦＮ）至肝炎病毒感染细胞。随着技术的不断改进，本法可用于治疗人类ＨＢＶ感染和获得性肝病。本研究是首次利用嗜肝ＤＮＡ病毒载体成 Researchers at Heidelberg University in Germany used the ability of Hepatitis B virus (HBV) or Hepadnavirus to infect hepatocytes and used it as a vector to deliver interferon (IFN) to hepatitis virus-infected cells in an animal model of hepatitis. With the continuous improvement of technology, this law can be used to treat human HBV infection and acquired liver disease. This study is the first to make use of hepadnavirus vectors
