Hamster cells are resistant to infection by most retroviruses, including Moloney murine leukemia virus (MoMLV) and gibbon ape leukemia viruses (GaLVs). We have constructed MoMLV-GaLV hybrid virions to identify viral and cellular determinants responsible for the inability of GaLV and MoMLV to infect hamster cells. The substitution of MoMLV core components for GaLV core components circumvents the resistance of hamster cells to infection by GaLV, demonstrating that hamster cells have receptors for GaLV but are not efficiently infected by this primate retrovirus because of a postpenetration block. In contrast, hamster cells are apparently resistant to MoMLV infection because although they bear a receptor for MoMLV, the receptor is nonfunctional. Treatment of CHO K1 or BHK 21 hamster cells with the glycosylation inhibitor tunicamycin allows the cells to be infected by MoMLV. The construction of MoMLV-GaLV hybrid virions that can efficiently infect resistant cells has allowed the identification of viral and cellular factors responsible for restricting infection of hamster cells by MoMLV and GaLV.
