Figure 1: CD4+CD25high Treg in peripheral blood samples by analysis of surface CD25, CCR5, CxCR4 and intracellular FoxP3 on CD4 T-cells. Representative three-color flow cytometric analysis of CD4+CD25high [2%] and CD4+CD25intermediate [15%] and CD4+CD25low/negative [83%] T-cells from HIV subject. For analysis plots, template of both mean fluorescence intensity [MFI] data and percentage positive data [% of cells expressing a particular antigen] were used.
