Cytoskeletal morphology differentiates types of phagocytosis. Phalloidin (A), which stains f-actin, andα-actinin (B) was used as cytoskeletal markers to compare cellular morphologies. BV-2 cells were treated with invasin 195 (1 μg/ml), Aβ25-35 (60 μm; 63.6 μg/ml), invasin397 (1 μg/ml), immune IgG (1 mg/ml), and mouse complement-opsonized zymosan (mOZ) (1 mg/ml) for 30 min before an additional 30 min incubation with microspheres. Images of cells were taken at 100×. These experiments are representative of three independent studies.
