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.
莫洛尼鼠白血病病毒(MuLV)的IC分离株具有嗜NB特性,它在产生源自嗜N或嗜B型MuLV的条件性缺陷或缺陷病毒颗粒的细胞中生长。随后释放的感染性MuLV被发现对Fv-1限制敏感,但传代后产生嗜NB特性的子代。这些结果表明,这种嗜NB特性的MuLV可通过与嗜N或嗜B型MuLV进行表型混合而获得对Fv-1限制的敏感性。因此提示,嗜NB特性的MuLV对Fv-1限制不敏感仅仅是因为它缺乏嗜性决定簇。
