Lectin-Fc(IgG) binding enhanced complement activation resulting in A. fumigatus killing. (a,b) Opsonization of the A. fumigatus conidia with the lectin-Fc(IgG) proteins increased the deposition of C3 protein, in relation to the control groups incubated with active or inactivated mouse serum as evaluated by (a) fluorescence microscopy (100×) and (b) flow cytometry displaying the fluorescence intensity of individual cells (* p < 0.05, ** p < 0.01, *** p < 0.001, compared to serum alone). Comparison among groups was performed by One-way ANOVA.
