Lymphocyte proliferation. PBMC from 5 subjects were stimulated with 200 ng/mL anti-CD3 antibody. Stimulation index (representing the mean of triplicate wells for each subject and each condition) in the presence of no added Tregs (black bars). Proliferation was suppressed by addition of Treg at a ratio 1 : 1 Treg to PBMC (grey bars), or at a ratio of 1 : 3 Treg to PBMC (hatched bars) in each subject.
