Abstract

Pseudotypes of vesicular stomatitis virus were prepared with avian sarcoma viruses and avian leukemia viruses representing five different subgroups. These pseudotypes display a host range restricted to that of the avian tumor virus when assayed on avian cells and are neutralized by subgroup-specific antisera. The efficiency of penetration of mammalian cells was assayed by using these vesicular stomatitis virus pseudotypes. Pseudotypes of avian tumor viruses belonging to subgroup D and of B77 virus were able to plate on mammalian cells with a high efficiency, whereas pseudotypes of other strains were not. The efficiency of penetration of the vesicular stomatitis virus pseudotypes was 10-2-to 10-3-fold higher than the efficiency of transformation of the corresponding avian tumor virus strain assayed on mammalian cells, suggesting that there are postpenetration blocks to the expression of transformation in these cells.

摘要

用代表五个不同亚群的禽肉瘤病毒和禽白血病病毒制备水泡性口炎病毒假型。当在禽细胞上进行检测时,这些假型显示出宿主范围仅限于禽肿瘤病毒的宿主范围,并且被亚群特异性抗血清中和。通过使用这些水泡性口炎病毒假型来检测其对哺乳动物细胞的穿透效率。属于D亚群的禽肿瘤病毒假型和B77病毒能够高效地感染哺乳动物细胞,而其他毒株的假型则不能。水泡性口炎病毒假型的穿透效率比在哺乳动物细胞上检测的相应禽肿瘤病毒株的转化效率高10 - 2至10 - 3倍,这表明在这些细胞中存在转化表达的穿透后障碍。
