Infections with HIVSF162(CCR5) and HIVNL4.3(Δvpr) showed that the hUNG2 nuclear isoform (but not the mitochondrial hUNG1 isoform) selectively disappeared between 1 and 7 days post-infection with HIVSF162(vpr+), but not with HIVNL4.3(Δvpr) (Figure 4D) (Eldin et al., 2014). This evidence concerns the gene CCR5 and infection.
