As depicted in the histograms displayed in Figure 4C, at day 12 post-HIV-1 infection in MTb-co-infected cells there was a significant reduction in levels of HIV-1Lai/Bal-env-κB I-Mut, HIV-1Lai/Bal-env-κB II-Mut, HIV-1Lai/Bal-env-κB I+II-Mut, and HIV-1Lai/Bal-env -N5-Mut in comparison to wild-type virus (Figure 4C). The gene discussed is ERVW-1; the disease is HIV-1 infection.
