Fig. 3. : Trypanosoma cruzi induces fibronectin (FN) deposition in the cardiac tissue during the chronic phase of infection. A: representative sections of the heart tissue of non-infected (NI) and infected C57BL/6 mice analysed by immunohistochemistry for FN deposition; B: quantitative data of FN-stained area (%) in the heart tissue of NI and T. cruzi-infected C57BL/6 and C3H/He mice; ***: p < 0.001, NI compared to T. cruzi-infected mice; #: p < 0.05, C57BL/6 compared to C3H/He lineage. Data obtained from three independent experiments (3 NI and 5 T. cruzi-infected mice per experiment).
