[Immune response in vaccinated and non-vaccinated mice infected with tick-borne encephalitis virus].

The paper deals with an investigation of an immune response in BALB/c mice immunized with tick-borne encephalitis (TBE) vaccine and infected with TBE virus and in non-immunized mice. The parameters of specific humoral (IgG and IgM) and cellular (gamma-interferon (IFN) and cell proliferation) immunities and the activity of cytokines (necrosis tumor factor-alpha, interleukin (IL)-1beta, IL-2, IL-6, IL-10, and IL-12) were studied. There were significant differences in the specific and nonspecific immune response of immunized and non-immunized animals. Noteworthy is the difference in the time course of changes in the levels of IL-6, IL-2, IL-12, and gamma-IFN in the immunized and non-immunized animals.
