Donation of N- or B-tropic phenotype to NB-tropic murine leukemia virus during mixed infections.

RESUMO
The IC isolate of Moloney murine leukemia virus (MuLV), which is NB-tropic, was grown in cells producing conditionally defective or defective virus particles derived from N- or B-tropic MuLV. The infectious MuLV that was then released was found to be sensitive to Fv-1 restriction but produced NB-tropic progeny upon passage. These results indicate that this NB-tropic MuLV can acquire sensitivity to Fv-1 restriction by phenotypic mixing with N- or B-tropic MuLV. It is thus suggested that NB-tropic MuLV is insensitive to Fv-1 restriction simply because it lacks the determinants of tropism.
