Nonetheless, P. brasiliensis infection reduced the number of alveolar (Figures 3(c)-3(d)) and tissue (Figures 3(e)-3(f)) macrophages as well as B cells (Figures 3(i)-3(j)) in the all postinfection periods evaluated; CD4 (Figures 3(k)-3(l)) and CD8 T (Figures 3(m)-3(n)) cells were also diminished in number at 48 h after infection, while DC (Figures 3(g)-3(h)) and NK (Figures 3(o)-3(p)) cells were increased in number at 96 h after challenge in those infected animals. This evidence concerns the gene CD8A and infection.
