Figure 2. DC Regulation Requires Cell Contact.
The experiment was designed as outlined in figure 1, and 96 well Transwell plates were used in this experiment. Each well contained complete RPMI medium (200 ul/well). LPMC were mixed with splenic OT2 T cells (ratio 2:1) and placed in the outer chamber (2×105 cells/well). In some cases, the outer chamber also contained DC (4×104 cells/well) derived from TI of Rag mice infected with Hpb for 2 wks (Hpb DC). Still other wells contained Hpb DC placed in the inner chamber with the LPMC + OT2 T cells in the outer chamber separated by a 0.4 um semi-permeable membrane. Data are mean ± SE of 3 independent experiments. *LPMC±OVA; or LPMC±OVA cultured without contact with Hpb DC, p<0.01.
