As IL-10 has been shown to limit the recruitment of CD11b+ Ly6C+ monocytes during infection with T. brucei[33] and we have previously shown that IL-10−/− mice infected with L. mexicana resolve their lesions [6], we hypothesized that monocyte recruitment following L. mexicana infection is impacted by IL-10 production at the lesion site. The gene discussed is IL10; the disease is infection.
