Figure 7. Inhibition of antigen stimulation is mediated by signaling from type II PKA.

Figure 7

Allogeneic day 5 dendritic cells (iDC) were incubated without (Unt, black bars) or with A) the indicated concentrations of type II anchoring inhibitor (IS, red bars) or the control (SCR, blue bars), or B) the indicated concentrations of type I anchoring inhibitor (RIAD, red bars) or the control (RSCR, blue bars) for 1 hr at 37°C, 5% CO2. The cells were collected, rinsed and replated. Then 0.1 µg/ml of protein antigen (CFP10) was added for 1 hr at 37°C, 5% CO2, and antigen specific CD4+ clonal T cells were added. IFN-γ production was assayed after 16 hours by ELISPOT. Data are an average of three donors. Error bars are S.E.M. Student ttest reveals significance, P<0.05(*).
