  1. HeLa, CMMT, Vero or OMK cells were stimulated with IFN-β and transduced 24 h later at a MOI of 0.5 or 5 (as determined on MDTF cells) with HIV-1, N-MLV, NB-MLV, B-MLV or SIVmac, as indicated. The same experiment was performed in parallel on MDTF cells treated or not with universal type I IFN. Fold restriction represents the ratio of untreated to IFN-treated cells to be transduced by the GFP-encoding retroviral vectors. A significant enhancement of retroviral restriction is defined as a ratio > 2 (in bold). Data are from a typical experiment representative of three independent experiments. nt: not tested.
