Abstract
The study discusses the relationship between the content of NF-KB and cytokine signaling suppressor 7 (SOCS7) in mononuclear peripheral blood cells (MNC) phosphorylated form of nuclear transcription factor inhibitor (NF-KB) and the production of MNC cytokines (TNF, IFN, IL-1β, IL-4, IL-10, IL-12) determining the state of congenital and adaptive immune response.
The content and level of phosphorylation of the nuclear transcription factor NF-KB (Ikba) inhibitor and the SOCS7 protein concentration were determined by enzyme immunoassay in MNC. In addition, the concentration of TNF, IFN, IL-1β, IL-4, IL-10, IL-12 was determined in cellular supernatants. The interrelations between the studied factors were evaluated by the method of linear regression analysis.
The results of the study indicate that the stage of recovery of community-acquired pneumonia is accompanied by a decrease in the level of IL-1, TNF and IL-4 and an increase in the production of Information. Also in the stage of convalescence there is a decrease in phosphorylation of Ikba and an increase in the concentration of SOCS7 in the OLS. The analysis revealed a significant effect on the level of phosphorylation of Ikba content in the cell SOCS7. Thus, a strong negative relationship between SOCS7 and phosphorylation of Ikba can be mediated by inhibition under its influence of STAT3/5 and MARK / SAPK-dependent cytokine production mechanisms, which allows to consider this factor as a therapeutic target for limiting excessive immunosuppression in pneumonia.
