Figure 1. Characteristics of bone-marrow-derived CD11c+ dendritic cells (DC).
A. The phenotype of DC were analyzed for expression levels of MHC I, MHC-II, CD80, CD86, CD40, and CCR7 using flow cytometry; mature DC (mDC) expressed higher levels of maturation molecules than immature DC (iDC). Representative histograms show marker expression levels (shaded) compared to those of the isotype controls (black line). B, C. An ELISA revealed that mDC produced higher levels of IL-12p70 and lower levels of IL-10 in culture supernatants after subsequent CD40L stimulation, compared to iDC (P < 0.05). The data are shown as the means (pg/mL) ± standard deviation (SD) of triplicate cultures from three independent experiments.
