Utilizing blocking antibodies specific to CD81 or the viral envelope protein E2, expression of entry factor mutants and mice with a targeted disruption of the SCARB1 gene validated uptake of HCV into murine hepatocytes in an HCV glycoprotein-mediated fashion. Taking advantage of the high mutational plasticity of HCV, three adaptive mutations in the viral glycoproteins E1 and E2 were identified that allowed the virus to enter cells expressing human SCARB1, CLDN1, OCLN and mouse CD81. Recently, a genetically humanized mouse model was constructed utilizing cell culture produced recombinant hepatitis C virus to activate a cellular encoded reporter (Dorner et al., 2011, in press ).
