Production of IL-1β by mice neutrophils. These cells were incubatedwith PLA₂ (3, 6, and 12 μg/mL) or RPMI (control) for 12 hours (a) and 24 hours (b) at 37°C in a humid atmosphere with 5% CO₂. Quantification was done by ELISA as described in 2.9. Each bar represents the average +/− SD of three independent groups. *P < 0.05 compared to the control.
