CD8 Tr cells do not suppress secondary responses. (A) 3-d secondary proliferation and (B) IFN-γ production by DC1-primed CD8 T cells induced by allogeneic monocytes plus CD8 Tr cells (1:1, 1:2, and 1:4 ratio). The stimulation index of naive CD8 T cells was calculated by the following formula: cpm [(DC1 − T + T reg + mono) − (T reg + mono)]/cpm (DC1 − T).
