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

Figure 4

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 fibrous-cavernous pulmonary tuberculosis (patient S., 53 years old, diagnosed with fibrous-cavernous tuberculosis of the upper lobe of the left lung in a phase of infiltration and semination, MTB (+)). The relative content of CD4⁺CD25^+hiFoxp3⁺ cells (upper-right quadrant) is 11%, CD4⁺CD25⁻Foxp3⁺ cells (upper-left quadrant) is 13,5%, CD4⁺CD25⁺ Foxp3⁻ cells (lower-right quadrant) is 25.3%.
