Figure 2

Frequencies of CD4+ and CD8+ T cells, and CD4+/CD8+ T-cell ratios. Percentages of CD4+ T cells (A) and CD8+ T cells (B), and CD4+/CD8+ T-cell ratios (C) in peripheral blood are exhibited. Frequencies of CD4+ T cells (D) and CD8+ T cells (E), and CD4+/CD8+ T-cell ratios (F) from bronchoalveolar lavage (BAL) fluid are shown. For cells from blood, n = 27 patients with Pneumocystis jirovecii pneumonia (PCP), and 17 patients without PCP. BAL fluid, n = 23 in PCP, and 14 patients in non-PCP groups. *P < 0.05; **P < 0.01; ***P < 0.001. NS, not significant.
