Defective interleukin-2 production and interleukin-2 receptor expression in pulmonary tuberculosis.

The evolution of Mycobacterium tuberculosis as an intracellular pathogen has led to a complex relationship between it and its host, the human mononuclear phagocyte. The products of M. tuberculosis-specific T lymphocytes are essential for macrophage activation for intracellular mycobacterial killing. However, dysfunction cell-mediated immune response to infection with M. tuberculosis may contribute to progressive primary infection or reactivation of endogenous foci of mycobacteria. Th1 cells produce IL-2, which is essential for proper cellular immunity. The aim of this study was to identify the variation in IL-2 activity and soluble IL-2 receptor (IL-2 R) in peripheral blood lymphocyte in patients suffering with pulmonary tuberculosis. A significant decrease in IL-2 and IL-2 receptor level was observed in patients with pulmonary tuberculosis when compared to normal controls. Our results suggested that patients with pulmonary tuberculosis had a defect in IL-2 production. Better understanding of these interactions will allow the development of increasingly specific immune-based interventions for prevention and treatment of tuberculosis.
