CpG induces maturation (CD83 expression) of DCs. Freshly prepared peripheral blood DCs were incubated for 3 days with GMCSF (800 units/ml) and oligonucleotides (2006, CpG phosphorothioate; 2117, methylated 2006; 2 μg/ml). Values (%) represent the percentage of CD83-positive cells. Results are representative of four independent experiments.
