Activation markers in T cell population from chagasic patients and uninfected controls.

<p>Averaged percentages of HLA-DR+/CD38+ CD4+ (<b>A</b>) and CD8+ (<b>B</b>) T lymphocytes in chagasic patients (CP) without (stages A+B = non-CARD, black dots n = 15) and with structural cardiac damage (stages C+D = CARD, black dots n = 12), healthy controls (HC, empty squares, n = 20) and non-chagasic cardiomyopathy (NCC, empty triangles, n = 28) donors. Representative density plots of CD38 and HLA-DR expression on CD4+ (<b>C</b>) and CD8+ (<b>D</b>) T cells; the percentage of CD38+/HLA-DR+ cells is shown in each quadrant. * <i>P</i><0.05 and ** <i>P</i><0.001.
