Аннотация
In spite of reports on cytokines induction by the Brucella DNA in murine model, there is no comparison between pathogenic and appropriate vaccine strains in human. We investigated the cytokines profile of human peripheral blood mononuclear cells (PBMCs) induced by DNA extracted from pathogenic isolates of Brucella melitensis and B. abortus as well as Rev1 and S19; the appropriate vaccine strains. It was observed that despite differential induction of Interleukin(IL)-12 and IL-10 production, identical IL-12/IL-10 concentration ratio was obtained by all Brucella strains DNAs that was 2 after 24 h and 4 after 5 days of incubation. In addition, IL-2 and Interferon(IFN)-gamma production were profoundly increased compared to the medium at day 3 and 5 respectively but IFN-alpha was not induced. Therefore, Brucella strains DNAs are Th1 inducing component with similar pattern in human PBMCs.
