Modulation of spontaneous apoptosis by addition of IL-2 and IFN-γ

Peripheral blood mononuclear cells (PBMC) from three patients and three controls were cultured in medium alone and in the presence of either IL-2 (100 U/ml) or IFN-γ (250 ng/ml). 7-aminoactinomycin D (7AAD) incorporation and the number of Bcl-2-expressing cells were detected by flow cytometry.
