MICE SERUM CYTOKINE LEVEL UNDER MUCOSAL IMMUNIZATION WITH OPPORTUNISTIC MICROBIAL ANTIGENS

Abstract

An important parameter of immunotropic preparation effect is the influence on the production of cytokines that provide the interaction between the effectors of both congenital and adaptive immunity. Cytokine level was determined in the work while using the methods of mucosal immunization with Immunovac-VP-4 and compared with the subcutaneous introduction of this preparation. In case of intranasal and peroral methods of antigen application IL-5, IL-6, and IL-12 expression was found to be elevated, the same was true for IL-1β, IL-5, IL-6, IL-12, and IFN-γ under the subcutaneous immunization. Resulting mice cytokine profile confirmed that irrespective of the method of Immunovac introduction, the activation of immune effectors occurred that was manifested in the increase in proinflammatory and regulatory cytokine levels. It was concluded that the introduction of opportunistic microbial antigens initiated the activation of the cascade of immunologic reactions and under the influence of synthesized cytokines the polarization of immune response was involved that was predominantly of Th1 type.
