Cytotoxic Activity of Dendritic Cells as a Possible Mechanism of Negative Regulation of T Lymphocytes in Pulmonary Tuberculosis

Figure 3

The number of freshly isolated PD-1⁺CD4⁺ and PD-1⁺CD8⁺ cells in PPD-anergic TB patients was higher than that of healthy donors. The numbers of PD-1⁺CD4⁺ (M ± S.E.) cells (a) and of PD-1⁺CD8⁺ cells (b) were detected in the peripheral blood of healthy donors: PPD-reactive and PPD-anergic TB patients.
