RESUMO
AIM: Study cytokine status in mice immunized with vaccines containing acellular pertussis component. MATERIALS AND METHODS: Vaccines developed in Mechnikov RIVS - acellular pertussis vaccine (aPV) and adsorbed pertussis-diphtheria-tetanus vaccine (aDTaP), containing a complex of protective antigens of pertussis microbe - were used in the study. F1 (CBAxC57B16) line mice weighing 12 - 14 g were immunized intraperitoneally 3 times at an interval of 7 days with aPV and aDTaP at human immunization dose (0.5 ml), containing 25 µg of pertussis component. Intact mice were used as a control group. Levels of IFN-,γ, IL-2, IL-4, IL-5, IL-12 cytokines were de- termined after each immunization in enzyme immunoassay using commercial test-systems from Cusabio (China). RESULTS: An increase of levels of IFN-γ, IL-2, IL-5, IL-12 and lack of stimulation of production of IL-4 was established in dynamics of immune response after administration of aPV and aDTaP vaccines. CONCLUSION: The data obtained indicate that immunization of mice with aPV and aDTaP vaccines resulted in activation of production of cytokines characteristic for im- mune response during pertussis infection and immunization with whole-cellular aDTP-vaccines.
