Effect of BaTX-I, BaTX-II, and BaPLA₂ on lipid body formation by J774A.1 macrophages. 2 × 10⁵ macrophages were incubated with toxins (6 µg/mL) or RPMI (control) for 60 minutes at 37°C in a humidified atmosphere of 5% CO₂ before the addition of opsonized zymosan particles. The number of lipid bodies stained with osmium tetroxide within macrophages was determined using phase-contrast microscopy. Values represent the mean ± S.E.M. from 3 independent experiments. *P ≤ 0.05 compared with control and ^# P ≤ 0.05 compared with control submitted to phagocytosis (ANOVA).
