摘要：
Introduction: CD4(+)CD25(+) T lymphocytes have been implicated in the regulation of host inflammatory response against Trypanosoma cruzi, and may be involved in the clinical course of the disease. Methods: Peripheral blood mononuclear cells from patients with chronic Chagas disease were cultured in the presence of T. cruzi recombinant antigens and assayed for lymphocytes at distinct time points. Results: It was possible to differentiate clinical forms of chronic Chagas disease at days 3 and 5 according to presence of CD4(+)CD25(+) T cells in cell cultures. Conclusions: Longer periods of cell culture proved to be potentially valuable for prospective evaluations of CD4(+)CD25(+) T lymphocytes in patients with chronic Chagas disease.
