    Abstract:
    Studies concerned evaluation of differences between parameters of cell-mediated immunity in mice, induced with whole-cell and acellular pertussis vaccines with subsequent challenge with B. pertussis strains harbouring different ptxS1/prn allele genes. In the study, concentrations of IFN-gamma/Il-2 and 1l-4/Il-5 in supernatants of cultured mice splenocytes have been determined to evaluate differences in Th1 or Th2 lymphocytes subpopulation response. Simultaneously, studies of intracellular expression of genes encoding of Il-2, Il-12, IFN-gamma and Il-4, Il-5, Il-10, Il-13 in mice splenocytes, and genes encoding factors involved in inflammatory process in the lung tissue (GM-CSF, TNF-alpha, Il-1beta, Il-6 i TGF-beta) have been performed on RNA level. The obtained results, confirmed high polarization of immunological response toward Th1 in mice immunized with DTP vaccine with whole-cell pertussis component, and toward Th2 in mice immunized with acellular pertussis vaccine. Inflammatory process in the lung tissue was more pronounced in animals immunized with whole-cell pertussis vaccine. There were no quantitative differences of analysed factors involved in the immune response among mice challenged B. pertussis strains containing different ptxS1/prn composition.
