Fig 6. Correlations between PD-L1⁺ on CD19⁺ cells and CD72⁺ on T cells.

(A) Correlations between frequencies of PD-L1 on CD19⁺ cells and frequencies of CD72 on CD4⁺ T cells and on CD8⁺ T cells. (B) Correlations between frequencies of IFN-γ-producing CD3⁺ T cells and MFI of CD72 on CD8⁺ T cells. (C) Correlations between frequencies of IFN-γ-producing CD3⁺ T cells and MFI of PD-1^hi on CD4⁺ T cells. All these correlations were determined in healthy individuals and in VL-HIV-1⁺ individuals. Correlations were determined by Spearman’s rank correlation. * = p<0.05 when comparing conditions. Each symbol corresponds to an individual.
