Comparison of the effect of SB with IFN-γ for the induction of costimulatory molecules.
The cells were treated with 500 IU/mL IFN-γ in the presence or absence of SB for 48 hours then analyzed by flow cytometry. Closed histograms (in black) represent medium-treated cells. Open histograms with the broken line and thin line represent SB-treated and IFN-γ–treated cells, respectively. Bold line histograms represent cells treated with SB and IFN-γ simultaneously 48 hours before the assay.
