The Role of Foxp3-Expressing Regulatory T Cells and T Helpers in Immunopathogenesis of Multidrug Resistant Pulmonary Tuberculosis

Figure 2

Individual bar chart of distribution of regulatory T cells in a population of CD4-positive lymphocytes of blood, expressing CD25 and Foxp3, in a patient with infiltrative pulmonary tuberculosis (patient N., 39 years old, diagnosed with infiltrative tuberculosis S_1-2 of the right lung in a phase of decay and semination, MTB (+)). The relative abundance of CD4⁺CD25^+hiFoxp3⁺ cells (upper-right quadrant) is 5%, CD4⁺CD25⁻Foxp3⁺ cells (upper-left quadrant) is 7%, CD4⁺CD25⁺Foxp3⁻ cells (lower-right quadrant) is 13.5%.
