Outline of Final Research Achievements

HBV is not eradicated by current antiviral therapies due to persistence of HBV cccDNA in host cells, and thus development of novel culture models for productive HBV infection is urgently needed, which will allow the study of HBV cccDNA eradication. To meet this need, we developed culture models of HBV infection using human induced pluripotent stem cell-derived hepatocyte lineages, including immature proliferating hepatic progenitor-like cell lines and differentiated hepatocyte-like cells. These cells were susceptible to HBV infection, produced HBV particles, and maintained innate immune responses. This study provides evidence that iPS-derived hepatic cell lines can be utilized for novel HBV culture models with genetic variation to investigate the interactions between HBV and host cells and the development of anti-HBV strategies.
