The capacity to secrete IL-2 by antigen-specific CD4 T cells is associated with increased CD25 expression. (A) Representative histogram of the CD25 expression on cytokine-negative, MIP-1β+IL-2, and MIP-1βIL-2+ CD4 T cells after 6 h of SEB stimulation of PBMCs. (B) The fraction of CD25+ CD4 T cells among the same subsets (n = 7). Statistical analysis was performed using the Mann-Whitney test.
