Determination of chemokines involved in monocyte chemoattraction. a The expression of different members of the monocyte chemoattractant protein family was evaluated by qPCR. Results are first normalised to the mean expression of two housekeeping genes (GAPDH and HPRT1) and then toward gold standard DC. The relative expression of nine different donor is represented as mean ± SE. *p < 0.05, ns p > 0.05 in the Tukey post hoc test. b The CCL2 and CCL8 concentration of “wash out” supernatants from mature DC seeded in the absence of exogenous stimuli for 24 h were determined by sandwich ELISA. The results are represented as mean ± SE of 8–12 different donors. *p < 0.05, ns p > 0.05 in the Tukey post hoc test.
