FIG. 7.

Dependency of STAT5 phosphorylation on CD127 expression. STAT5 phosphorylation (ΔpSTAT5 MFI) in response to IL-7 stimulation was plotted as a function of CD127 expression (CD127 MFI) for each CD4⁺ T-cell subset. Since four CD4⁺ T-cell subsets were analyzed per sample (NTreg, Nv, MTreg, and Mem), four data points were plotted per patient. Cells were stimulated with low doses of IL-7 (A) and high doses of IL-7 (B) in the group of healthy donors (HD) and viremic patients (VIR).
