| Sumario: | At present, the search for biomarkers, which indicate the presence of tense antiplague immunity, is continuing. The aim of the study was to determine the parameters of cellular and humoral immunity in persons vaccinated with the plague vaccine according to epidemiological indications and to characterize the correlation interrelations between them in the dynamics of the antiplague response formation. Blood samples from 114 people living in the territory of the Pre-Caspian sandy natural plague foci were investigated. Using commercial kits, the production of cytokines IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-18, IFNγ, TNFα (Vector-Best, Russia) IL-17A (eBioscience, Austria), immunoglobulins IgG, IgM, IgA (Vector-Best, Russia) was determined on the enzyme immunoassay analyzer LAZURIT (Dynex Technologies, США). Blood leukocyte immunophenotyping was carried out using f luorochrome-labeled monoclonal antibodies Cyto-Stat CD45-FITC, CD4-PE, CD8-ECD, CD3-PC5 (Beckman Coulter, США) on the CyAn ADP DakoCytomation f low cytometer (Denmark). Obtained data analysis revealed a number of differences in the production of detectable cytokines (TNFα, IL-1β, IL-2, IL-4, IL-6, IL-17) between groups of vaccinated and first-vaccinated people. However, human blood cells, regardless of the multiplicity of the graft, retained their functional reactivity and were able to actively secrete the majority of the analyzed cytokines (8 of 10) in response to stimulation with concanavalin A. Diagnostically significant changes in the concentration of IFNγ, TNFα and IL-4 were detected for the characteristics of a specific antiplague response. For these marker cytokines, the greatest number of correlations have been revealed, both with each other and with changes in the level of other parameters: cytokines, immunoglobulins, T cells. The revealed multiple correlation links between the cytokine and immune status indices indicate the activation of both the cellular and humoral components of the antiplague immune response. The informative value of the complex analysis application of correlation interrelations between the humoral and cellular immunity parameters is shown to assess the level of immunological efficacy (actual vaccination) of vaccination in persons vaccinated against plague. |
