Figure 6. Reduction in absolute Treg cell number in chronic HIV infection.

Figure 6

The frequency of Treg cells in HIV+ subjects defined as CD4+CD25+ (A) and CD4+CD25+ FOXP3+ (C) was first enumerated by immunofluroescence and absolute numbers of these subsets derived based on absolute CD4 T cell count of each subject. Bars represent mean values with SEM. P-values were calculated using Student's t test. Correlation between absolute Treg cell numbers and CD4 T cell count was determined using GraphPad PRISM software. (B) Correlation between CD4+CD25+ number and CD4 T cell count. (D) Correlation between CD4+CD25+FoxP3+ number and absolute CD4 cell count. P-values were calculated using Spearman's rho linear regression.
