Figure 4From: 5' long terminal repeat (LTR)-selective methylation of latently infected HIV-1 provirus that is demethylated by reactivation signalsSelective analysis of CpG methylation of two LTRs. Methylation of CpG sites in each plasmid clone is displayed. Closed and open circles indicate methylated and unmethylated CpG sites, respectively. TNF-α treated cells are harvested at the time points indicated in the middle. (-), ACH-2 cells harvested before TNF-α treatment.Back to article page
