THE PHENOTYPE AND FUNCTION OF MONOCYTES IN PATIENTS WITH PULMONARY TUBERCULOSIS

Abstract

Abstract. Peripheral blood monocytes were investigated in the patients with pulmonary tuberculosis. It was established that population of CD14+16+ monocytes was twofold increased in the patients with tuberculosis. The higher level of CD14+CD16+ monocytes was associated with decreasing number of monocytes with intracellular TNF–α, and negative correlation between these parameters was revealed. On the contrary, the higher level of CD14+CD16+ monocytes was connected with increased number of IL–10–producing monocytes. IL–10–producing cells were established mainly in the population of CD16+ monocytes and so population of CD14+CD16+ monocytes may represent the cells with suppressive activity. Really, the CD14+CD16+ monocytes were increased in patients with defective antigen specific response. Enhancement of CD14+CD16+ monocytes was observed in patients with active tuberculosis independently of form and dissemination of disease and did not connected with concomitant viral or bacterial infection.
