| Sumario: | This study presents data upon the effects of CpG oligonucleotide substance (CpG ODN 2006). The commercial preparation was applied in vitro as a single agent, or in combination with various cytokine production inducers. Spontaneous and induced cytokine levels were tested in cultures of human blood cells taken from the persons before and after anti-plague vaccination. It has been shown that the vaccination had no effect upon spontaneous production of cytokines participating in innate (IL-8, TNFα) and adaptive (IFNγ, IL-4) immunity. CpG ODN 2006 proved to exert effects upon functional activity of human blood Th1 and Th2 pro-inflammatory cytokines after the first vaccination with live anti-plague vaccine, being reflected as higher Th1/ proinflammatory (IL-17 and IFNг) and Th2/ antiinflammatory (IL-4) cytokine production. Postvaccination changes of IgM, IgG, IgA, and IgE contents were non-significant. Following repeated vaccination, the CpG ODN 2006 induced an increase of IL-4 and IL-17 production in blood cells, as well as decrease in IFNг levels. Thus, the ability of CpG ODN 2006 to activate the cells participating in innate and adaptive immunity opens some prospects for usage of this oligodeoxynucleotide in the development of more efficient anti-plague vaccines. |
