As depicted in Figures 2A, B, HIV infection itself did not induce any IFNα2 and also the treatment with IFNα14 and IFNβ did not result in the expression of IFNα2 by an IFN-mediated feedback loop suggesting that we just detected the IFNα2 that was added for stimulation. This evidence concerns the gene IFNB1 and HIV infectious disease.
