We have investigated the IFN-mediated inhibition of human parainfluenza virus-3 (HPIV-3) replication in cultured human A549 cells. IFN-alpha inhibited the virus yield significantly with concomitant reduction of viral RNA accumulation by more than 90%. Further studies indicated that the inhibitory action of IFN was at the level of primary transcription of HPIV3 replication. Since the IFN-inducible protein, MxA, has been shown to inhibit virus replication in several RNA viruses, we examined the role of MxA in HPIV-3 replication using a stably transfected human glioblastoma cell line expressing MxA. In these cells HPIV-3 replication was decreased by more than 100-fold depending on the virus dosage used with concomitant inhibition of viral RNA synthesis by about 80%. However, the viral primary transcription was not affected in this MxA-producing cell line. In contrast, in the parental cell line IFN-mediated inhibition occurred at the primary transcription step of HPIV-3 replication. These data suggest that in addition to MxA, other IFN-inducible proteins are involved in the anti-HPIV-3 effect of IFN in both the cell lines used.
