Figure 2. RA-DCs release tolerogenic cytokines.
The fold increase (mean ± SEM, n=8) in the concentration of the indicated soluble factors in the supernatants of RA-DCs are shown compared to the control moDCs (set as 1) at day 6 of culture. The data from 1 donor were excluded for TGF-β1, because this donor had 4-fold less TGF-β1 in RA-DCs than in moDCs. This was in contrast with all other donors showing the opposite trend (*p<0.05; **p<0.01; ***p<0.001).
