We previously demonstrated that cellular mRNAs are degraded in CD4 positive lymphocytes infected by the human immunodeficiency virus, HIV-1, but not in cells infected by the simian lentivirus, SIV. To begin to define the molecular mechanisms underlying this RNA degradation, we have established anin vitroRNA degradation assay utilizing extracts from both infected and uninfected cells. We found thatin...
We have examined the effects of interferon (IFN)-α/β on HIV-1 and SIV replication in CD4+ T-cell lines. To enable us to examine these effects on a single cycle of virus replication, cells were synchronously infected with HIV-1 LAI or SIV mac251. Cell lines included MT4 cells which were responsive to IFN and, as controls, C8166 cells which failed to respond to interferon treatment. Similar to previous...
