Fig. 3From: Foxp3+Helios+ regulatory T cells are associated with monocyte subsets and their PD-1 expression during acute HIV-1 infectionCorrelations between the frequency of Foxp3+Helios+ Treg cells and monocyte subsets and their PD-1 expression in HIV-1-infected individuals. Correlation between the frequency of Foxp3+Helios+CD45RA+ Treg cells and CD14++CD16+ monocyte subsets (a), PD-1 density on CD14++CD16+ monocytes (b), and PD-1 density on CD14+CD16++ monocytes (c) during acute HIV-1 infection. Correlation between the frequency of Foxp3+Helios+CD45RO+ Treg cells and CD14++CD16+ monocyte subsets (d), PD-1 density on CD14++CD16+ monocytes (e), and PD-1 density on CD14+CD16++ monocytes (f) during acute HIV-1 infection. Correlations were analyzed by calculating Spearman’s correlation coefficientBack to article page
