Phenotypic properties of OCs and DCs.(A) OCs and DCs were cultured with lipopolysaccharide (LPS), interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β), or sCD40L for 48 hours. Cells were harvested and stained with antibodies for flow cytometric assay. (B) Summarized data (mean ± SEM) for mean fluorescence intensity (MFI) of cells from 3 different donors are shown.
