Figure 6. IL-6 levels bear a significant negative correlation with higher CCR5 expressing Tregs.

A. A representative scatter diagram depicting the Spearman correlation between TNF-α (pg/ml), CCR5 expression (MFI) on CD4+CD25^high Tregs, CD25^intermediate and CD25^low/negative effector cell in PBMCs from HIV-1 infected individuals. B. A representative scatter diagram depicting the Spearman correlation between IL-6 (pg/ml), percent CCR5+ cell on CD4+CD25^high Tregs, CD25^intermediate and CD25^low/negative effector cell in PBMCs from HIV-1 infected individuals. The solid line represents the linear regression of points. Rho and p-values are from the Spearman rank correlation test.
