Effect of adding different numbers of CD4+CD25+ T cells upon degree of suppression. Various numbers of CD4+CD25+ T cells were added to a constant number of CD4+CD25− T cells (5 × 103). Cells were stimulated with 1.5 μg/mL anti-CD3 and 1 × 104 T cell-depleted accessory cells for 7 days. [3H]thymidine was added for the final 18 hours of culture. The degree of suppression increased as the number of CD4+CD25+ T cells increased. All points were done in sextuplicate, and error bars represent SEM.
