Infection of mice with T. cruzi led to the accumulation of Gr1+ cells (i.e., neutrophils), Gr1+/CD11c+cells (i.e., plasmacytoid dendritic cells), CD11b+cells (i.e., myeloid lineage cells), and F4/80+cells (i.e., macrophages) in their spleens when compared with uninfected control mice (Figures 4(a)–4(d)). This evidence concerns the gene ITGAX and infection.
