Fig. 4. Quantification of the cytokines secreted by DCs in presence of NPs.

Fig. 4

DCs were incubated at 37°C in the presence of LPS (2μg/ml) and/or gold NPs (0.5mM) for 24 hours, then the supernatants were collected and used to determine the concentration of IL-6 and IL-12p70 as indicated in the material and methods section. A control was performed without additive: LPS and NPs. The results correspond to the mean value of three independents experiments. ** denotes a significant difference between the indicated experimental groups (p<0.05).
