EVs are able to stimulate cytokines and chemokines production by macrophages. 5 × 104 macrophages were stimulated with 0.4 μg of A. fumigatus EVs. Secretion of inflammatory mediators TNF-α (A), CCL2 (B), IFN-γ (C), and IL-10 (D) were quantified. Cells pre-incubated with EVs were challenged with 5 × 105 (MOI 10:1) conidia of A. fumigatus for 4 and 6 h. Production of inflammatory mediators TNF-α (E), CCL2 (F), IFN-γ (G), and IL-10 (H), during in vitro challenge with A. fumigatus, were quantified. Data are representative of three experiments. ∗Represents statistically differences between the indicated groups (p < 0.05) as determined by One Way-ANOVA and two-sample independent t-tests.
