Cytokine production by immature dendritic cells (iDC) or mature dendritic cells (mDCs) incubated or not with allogeneic or syngeneic apoptotic thymocytes. Surface marker transforming growth factor-latency associated peptide (LAP) and intracell staining for interleukin-10 (IL-10) and IL-12 (a) were performed as described in the Materials and methods. Statistic analysis on mean of fluorescence intensity of LAP (b) and IL-12 production (c) were also performed. Results are presented as mean ± SD and are representative of three independent experiments. *P < 0·05 **P < 0·005.
