The percentages of CD4+ T cells and CM CD4+ T cells were significantly higher in Group 4 (ART + PH-797804 since week 6) compared to Group 3 (ART alone since week 6) (p = 0.02 for CD4+ T cells and p = 0.01 for CM CD4+ T cells) (Fig 8A and 8B) and differences were not significant when Group 4 was compared to Group 5 (ART since week 1 post-infection). This evidence concerns the gene CD4 and infection.
