Day 5 immature DCs were cultured in the absence of cytokine or in GM-CSF plus IL-4 in the absence or presence of 25 ng/mL IFN-γ, 25 ng/mL IFN-γ plus 100 ng/mL M-CSF, or 100 ng/mL M-CSF plus 100 ng/mL IL-6.
ND indicates not done.
After 1 day, membrane CD115 expression was analyzed by FACS.
After 3 days, CD1a and CD14 expression were analyzed by FACS. For CD1a, CD14, and CD115, results are expressed in MFI ± values, mean SD of 4 separate experiments.
After 3 days, cells were further stimulated for 24 hours with LPS, and CD83 was analyzed by FACS. Results are expressed in percentage of positive cells.
After 2 days, cells were used as stimulatory cells in primary allogeneic MLRs.
After 2 days, cells were stimulated for 24 hours with LPS before being used as stimulatory cells in primary allogeneic MLRs. Results are expressed in counts per minute × 10−3 as mean ± SD of quadruplicate values and are representative of 1 of 3 experiments.
