Control, macrophages interacting with no yeast-like cells. * P < 0.05 when compared to WT strain. In B, similar experiments to those described in panel A were performed but with human cells previously preincubated with 5 μg mL −1 polymyxin B and 10 μg mL −1 anti-TLR2 (+anti-TLR2), with 5 μg mL −1 polymyxin B and 200 μg mL −1 L-rhamnose (+Rhamnose), 5 μg mL −1 polymyxin B and 10 μg mL −1 anti-TLR4 (+anti-TLR4), or with 5 μg mL −1 polymyxin B and 200 μg mL −1 laminarin (+Laminarin). No treatment refers to cells preincubated only with 5 μg mL −1 polymyxin B. Results correspond to cells in the late stage of phagocytosis. For all cases, 100% corresponds to the system with no treatment and the absolute values were similar to those shown in panel A.

    Phagocytosis of RmlD -silenced S. schenckii by human monocyte-derived macrophages. In A, Acridine Orange-labeled yeast-like cells were coincubated with human monocyte-derived macrophages at a macrophage-yeast ratio 1:6, for 2 h at 37 °C and 5% (v/v) CO 2 . The macrophages were gated by FACS and 50,000 cells were counted per sample. Macrophages interacting with at least one fluorescent yeast cell were included as counted events. Control, macrophages interacting with no yeast-like cells. * P < 0.05 when compared to WT strain. In B, similar experiments to those described in panel A were performed but with human cells previously preincubated with 5 μg mL −1 polymyxin B and 10 μg mL −1 anti-TLR2 (+anti-TLR2), with 5 μg mL −1 polymyxin B and 200 μg mL −1 L-rhamnose (+Rhamnose), 5 μg mL −1 polymyxin B and 10 μg mL −1 anti-TLR4 (+anti-TLR4), or with 5 μg mL −1 polymyxin B and 200 μg mL −1 laminarin (+Laminarin). No treatment refers to cells preincubated only with 5 μg mL −1 polymyxin B. Results correspond to cells in the late stage of phagocytosis.

For both panels, data represent means ± SD from six donors assayed by duplicate. WT, strain 1099–18 ATCC MYA 4821. Strains HSS29 and HSS30 were transformed with pBGgHg; while HSS20-HSS25 with pBGgHg- RmlD .

    Mortality of Galleria mellonella larvae inoculated with RmlD -silenced Sporothrix schenckii . Groups containing 30 larvae were inoculated with 1 × 10 5 yeast-like cells in 10 μL of PBS and survival recorded daily for 15 days. Data are shown in Kaplan–Meier plots. The statistical analysis showed no differences among the WT, HSS29, and HSS30 strains ( P = 0.68), but the silenced strains generated survival curves with significantly increased median survival times ( P < 0.05). When compared among them, no differences were observed in the curves generated with strains HSS20, HSS21, and HSS22 ( P = 0.76), nor with those generated with strains HSS23, HSS24, and HSS25 ( P = 0.88). WT, strain 1099–18 ATCC MYA 4821. Strains HSS29 and HSS30 were transformed with pBGgHg; while HSS20-HSS25 with pBGgHg- RmlD .
