ZK cells and primary AMs with MS^-/- reduced binding and phagocytosis of TiO₂ (A) and fluorescently labeled heat-killed S. aureus (B) in comparison to the wild-type primary AMs. TiO₂, 50 μg/ml; the ratio of S. aureus to cells was 50:1. Values represent the mean ± SD. **Significant difference from WT control, P < 0.001, n = 4.
