  • a The effect of CI-959-A on differentiation of DCs from PBMCs was determined. CD83DCs were differentiated by culturing PBMCs in the presence of GM-CSF and IL-4 for 7 days, and CD83+ DCs were differentiated by using GM-CSF, IL-4, and TNF-α. In each experiment, five independent cultures were used. The DC differentiation rate was calculated as follows: 100 × (number of DCs differentiated/number of PBMCs used). Means ± standard deviations are shown.

  • b P < 0.05 compared with no compound.

  • c ND, not determined.

  • d P < 0.01 compared with no compound.

  • e P < 0.05 compared with CI-959.
