Figure 3: Up-regulated expression change of CD80 was observed on samples S4 and S9 in SFI dosages of 1/20 & 1/40. For expression change of HLA-DR, upregulation of the marker was seen on S4 in SFI of 1/20 & 1/40 and S9 in SFI of 1/40 respectively. Out of the eight MDDC samples S2 to S5 and S9 to S12, only S4 and S9 were activated by SFI in the experiments.
