Calcium signaling inhibits IL-12 production by DCs.
DCs were activated with IFN-γ, TNF-α, and CD40L in the presence of the indicated concentrations of CI, and IL-12 p70 production was measured by ELISA. Levels of p70 IL-12 production by DCs activated with IFN-γ, TNF-α, and CD40L were 2000 to 3000 pg/mL. Results are based on triplicate cultures from a single representative experiment with SEM. Three other experiments demonstrated similar results.
