(A) Cells from all donors support HIV-1 infection. HIV-1-specific RT-qPCR was used to assess HIV-1 expression levels at the end of the infection step of each experiment. (B) No significant difference in the overall HERV-K HML-2 expression and marked donor variability is observed in HIV-1 infection of CD4⁺ T cells. HERV-K HML-2-specific RT-qPCR was used to assess overall expression levels at the end of the infection step of each experiment. (C) No correlation between HIV-1 expression levels and a change in HERV-K HML-2 expression was detected.
