Fig 2. HIV VL is negatively correlated with the proportion of CD4+ MTB-specific T-cells secreting IFN-γ and IL-2.

Graph shows Spearman’s rank correlation of proportion of PPD-specific CD4+ IFN-γ and IL-2-dual-secreting cells with HIV VL. Participants with both active TB/HIV (closed circles) and LTBI/HIV (open circles) and a positive response to PPD are shown (n = 16).
