Figure 3. Expression level of cytokines: BALB/c and C57BL/6 derived macrophages were infected with the stationary phase of promastigotes as test groups. Cell sediments were collected 24 hours post infection from test groups (white bar) and controls (black bar) for IL-10 and IL-12 expression. (A) The expression levels of IL-10 and IL-12 in BALB/c derived macrophages. (B) The mRNA levels of IL-10 and IL-12 in C57BL/6 derived macrophages.
