As shown in Figure 4C, wild type and SIT1-reconstituted C. glabrata yeast cells, but not sit1Δ cells, showed enhanced survival to macrophages expressing wild type Fpn only when grown in the presence of ferrichrome prior to infection, as interpreted from the increased number of CFU when compared to the wild type C. glabrata strain grown in the absence of FC (dashed line set at 100). The gene discussed is SLC40A1; the disease is infection.
