IFNA1 and HIV-1 infection: We quantitated differences between transcriptome changes induced after stimulation with each interferon and corresponding changes induced upon HIV-1Bal infection using the Euclidean method: ∑i=1n(qi−pi)2 (where p and q are gene expression levels induced by HIV-1 infection (p) or IFN stimulation (q) and i denotes the gene in the datasets that are being compared) (Figure 1c).
