FeLV infection of NIH 3T3 and BHK cells expressing FeLV receptors can be rescued by fusion of cells with murine MDTF cells or with human TE671 cells. (A) Fused MDTF-3T3/feTHTR1 cells and MDTF-3T3/huFLVCR1 cells were tested for susceptibility to LacZ-encoding FeLV-A and FeLV-C. MDTF-3T3/huFLVCR1 fused cells were also used as controls to show that the fusion process was not responsible for enhancement in FeLV-A infection. Titers are averages of three infection experiments. Arrows, infection titers of zero; ND, not determined. (B) FeLV susceptibility of human TE671 cells fused with NIH 3T3/feTHTR1 cells and susceptibility of MDTF cells fused with BHK/feTHTR1 cells. Titers are averages of three infection experiments. Standard deviation bars are shown. Arrows, infection titers of zero; ND, not determined.
