Comparative T-cell stimulatory capacity of the different MΦ and differentially generated DC. Unstimulated and LPS-stimulated MΦ/DC were tested in mixed lymphocyte reactions. MΦ and DC were cultured at ratios of 1:10 (blue), 1:30 (red); 1:90 (green) with lymphocytes. The * indicates a statistically significant higher activity of LPS-stimulated cells. The p value for MΦ was 0.04, for MoDC 0.02, FL-BMDC 0.05 and for GM-BMDC 0.006. Standard deviations of triplicates are shown and the data are representative of three independent experiments.
