NFKB1 and infection: Furthermore, whereas HIV-1 protein expression levels are higher after infection by HIV-1 env−gfp+ WT than by HIV-1 env−gfp+ D116N viruses (Fig. 1B), the uDNA expression presents the same modulation profile in WT and D116N conditions, indicating that this modulation by the NF-κB pathway is independent of HIV-1 protein levels.
