In AKR mouse cells chronically infected with a murine leukemia virus, treatment with interferon for nine days resulted in sustained inhibition of extracellular production of murine leukemia virus but no inhibition of viral intracellular p30 antigen or of reverse transcriptase. Removal of interferon resulted in rapid reversal of these effects. Interferon-treated mouse L-cells were infected with high multiplicities of vesicular stomatitis virus or herpes simplex virus type 1. Infectious virus and intracellular viral antigen were rapidly eliminated from the interferon-treated cultures infected with herpes simplex virus. In cultures infected with vesicular stomatitis virus, titers of virus remained low in interferon-treated cells, but after about two weeks they rose rapidly and the cultures were destroyed. If treatment with interferon was reinstituted as late as nine days after primary infection, infectious vesicular stomatitis virus was eliminated, and there was no evidence for survival of the viral genome in these cultures. In the cultures infected with murine leukemia virus, inhibition of production of virus by treatment with interferon was possible, but the viral genome was not eliminated. In cells acutely infected with vesicular stomatitis virus or herpes simplex virus, however, the viral genomes were apparently eliminated from cultures treated with interferon.

The interaction of endogenous type C viruses with superinfecting herpes simplex virus type 2 (HSV-2) was investigated in two murine cell lines. Replication of HSV-2 was suboptimal in random-bred Swiss/3T3A cells and, in initial experiments, infection with a low virus-to-cell ratio resulted in carrier cultures with enhanced murine leukemia virus (MuLV) p30 expression. Immunofluorescence tests with Swiss/3T3A cells productively infected with HSV-2 also showed HSV-associated cytoplasmic antigens and enhanced MuLV p30 expression when compared with uninfected controls. Inactivation of HSV-2 with UV light did not abolish this reaction, although the number of cells expressing p30 was reduced. HSV-2 replicated more efficiently in a line of NIH Swiss cells (N c1 A c1 10). These cells are not readily inducible for type C expression by conventional methods; however, untreated and UV-inactivated HSV-2 induced both HSV-2-associated antigens and MuLV p30 in these cells. Although the Birch strain of human cytomegalovirus induced MuLV p30, neither mouse cytomegalovirus nor vesicular stomatitis virus induced MuLV p30 in either cell line.
