Inhibition of allogeneic T-cell response by Kupffer cells expressing indoleamine 2,3-dioxygenase

Figure 3 Reduction of allogeneic T-cell stimulation by IDO and FasL-expressing KC. Naive lymphocyte (LC), naive KC, KC pretreated with IFN-γ were coincubated with allogeneic spleen T-cell for 5 d and cell proliferation measured by ³H-TdR incorporation. ^aP < 0.05 vs KC group.
