THE INHIBITORY EFFECTS OF VSV INFECTION ON MULV PRODUCTION OCCUR BETWEEN SYNTHESIS AND RELEASE OF MULV GENOMIC RNA
Abstract
The inhibitory effects of VSV infection on MuLV production were investigated using the VSV temperature-sensitive mutants t1B17(I & V), tsT1026(I), tsG22(II), and ts052(II). At the permissive temperature, all four mutants suppressed the release of virion-associated MuLV gRNA by approximately 98% within 0.5 to 2.5 hr post infection. At the restrictive temperature and in the absence of cell killing, infection with t1B17(I & V) inhibited the release of MuLV gRNA, while tsT1026(I) and tsG22(II) did not. In contrast, ts052(II) inhibited the release of MuLV gRNA and induced cell killing. During the same time period and at either temperature, all four mutants did not suppress either MuLV-associated protein release or intracellular MuLV sRNA synthesis. These results indicate that VSV inhibits MULV gRNA release at a level somewhere between the synthesis and release of newly synthesized gRNA.
