FIGURE 4.
A. fumigatus killing by macrophages. 5 × 104 RAW 264.7 macrophages were stimulated with 0.1, 0.2, and 0.4 μg of EVs (measured as total protein content) for 5 h. After that, the macrophages were challenged with 5 × 105 (MOI 10:1) conidia of A. fumigatus for 6 h. The amount of live conidia was quantified in YG media as unit forming colony (UFC). Data are representative of three experiments. ∗ Represents statistically differences between the indicated groups (p < 0.05) as determined by One Way-ANOVA.
