Immunostimulating effect of AMB on TNF-α production. Macrophages (105 cells per well) were cultured with various combinations of immunostimulants after an activation phase of 5 h. TNF-α production was determined as described in Materials and Methods. (A) TNF-α production as a function of IFN-γ concentration. □, IFN-γ alone; ○, IFN-γ with AMB (0.3 μg/ml); ●, IFN-γ with LPS (5 μg/ml); ■, IFN-γ with AMB (0.3 μg/ml) and LPS (5 μg/ml). (B) TNF-α production as a function of AMB concentration. ■, AMB alone; ●, AMB with LPS (5 μg/ml); ○, AMB with IFN-γ (5 IU/ml); □, AMB with IFN-γ (5 IU/ml) and LPS (5 μg/ml).
