Abstract

Summary

The reduced rate of synthesis, maturation and degradation as well as the level of accumulation of the intracellular virus proteins in VSV-infected cells may account for the overall reduction (less than 10-fold) of progeny virion yield due to interferon (IFN); however, the deficiency of the virions proteins, G and M, which apparently caused a drastic loss of infectivity of these progeny virions (about 1000-fold) cannot be easily explained, because the concentrations of G and M proteins relative to other virus proteins were not reduced in the cell. In fact, intracellular M protein was significantly increased. Moreover, the virus proteins in IFN-treated and control cells were synthesized and accumulated in large excess of the amount incorporated into the released virions. The reduction in the intracellular activity of GlcNac-P-P-Dol transferase did not appear to play a direct role in the antiviral mechanism in this system. Our results, however, do suggest that the deficiency of G and M proteins in the virion is related to specific inhibition of the incorporation of either or both of these proteins in the virus assembly process.
