Research Abstract |
In the present study, basic research was performed using cell culture system and human hepatocyte chimeric mice for clarifying the differeces between hepatitis B virus (HBV) genotype A and C. Lamivudine-resistant clones and lamivudine plus entecavir-resistant clones had similar tenofovir (TDF) susceptibilities to wild type clones. However, lamivudine plus adefovir-resistant clones acquired tolerance to TDF. Comparing between HBV genotype A and genotype C, the susceptibility to TDF in HBV genotype A was lower than that in HBV genotype C.
