SECRETION OF IL-12, IL-27 BY MONONUCLEAR LEUKOCYTES AND EXPRESSION OF THEIR RECEPTORS ON T-LYMPHOCYTES IN CONDITIONS OF DIRECTED CELL INDUCTION IN VITRO IN PULMONARY TUBERCULOSIS
The article presents the results of studies concerning secretion of cytokines belonging to interleukin 12 family, i.e., IL-12р70, IL-12р40, IL-12р35 and IL-27 in mononuclear blood leukocytes, as well as expression of their specific receptors on T-lymphocytes from tuberculosis patients under the in v...

| Sumario: | The article presents the results of studies concerning secretion of cytokines belonging to interleukin 12 family, i.e., IL-12р70, IL-12р40, IL-12р35 and IL-27 in mononuclear blood leukocytes, as well as expression of their specific receptors on T-lymphocytes from tuberculosis patients under the in vitro conditions of directed (resp., antigen- and cytokine-mediated) cell induction. In patients with pulmonary TB, we have registered suppression of both spontaneous and BCG-induced secretion of IL-12р70 and IL- 12р35, along with overproduction of IL-12р40 and IL-27. Furthermore, a decrease in relative contents of СD3+gp130+,CD3+IL12Rβ2+ lymphocytes were revealed in the in vitro IL-12/IL-27 induction tests, as well as increased concentration of T-cells with high expression of the inhibitory molecule WSX-1 (CD3+WSX-1+hi). It was shown that the detectable changes are unidirectional in most cases, being dependent on clinical form of the disease and sensitivity of the etiological agent to anti-tuberculosis drugs. |
