IL-8 synthesis by PMN stimulated with viable BCG or LPS. PMN were cultured for 3.5 or 18 h in the presence of BCG (106 CFU/ml) or LPS (0.1 μg/ml) as indicated in the figure legend. Supernatants were harvested, and IL-8 content was measured by ELISA. The figure bars show the combined results (mean values of duplicate samples) of three independent experiments (SDs < 20%).
