Supplementary Material

Supplementary Figure S1: The high levels of IL-17A, IL-6 and NOx were detected in the serum of chronically T. cruzi-infected mice (Figures S1(a) and S1(b)), resembling chronic chagasic patients [4]. Anti-TNF therapy tended to decrease the levels of IL-17A, Il-6 and NOx in the serum in comparison with saline-injected chronically infected mice.

Supplementary Figure S2: At 120 dpi, chronically Colombian-infected C57BL/6 mice show CD8-enriched myocarditis [18]. Anti-TNF therapy did not diminish the general inflammatory foci composed of CD8+, CD4+, and F4/80+ macrophages) (Figure S2(a)) but reduced the number of CD8+ cells infiltrating the cardiac tissue (Figures S2(b) and S2(c)). Therefore, we tested whether it was a site restricted effect examining the cell composition of a secondary lymphoid tissue. The frequencies of CD4+ and CD8+ T-cells in the spleen persisted unchanged after anti-TNF administration (Figure S2(d)).
