Abstract:

The current study was undertaken to certify the immunological adjuvant effect of recombinant IL-2,IL-4 and IFN-γ of porcine on the foot-and-mouth disease synthetic peptide vaccine.The changes of antibody and IL-4,IL-10,IL-17 and IFN-γ levels of porcines injected with synthetic peptide vaccine against foot-and-mouth disease and recombinant IL-2,IL-4 and IFN-γ of porcine,respectively.The results showed that the recombinant protein we made all had good biological activity.IL-2 and IFN-γ protein significantly increased the level of antibody against foot-and-mouth disease (P<0.01),while IL-4 appeared to have a suppressive effect (P<0.01).Recombinant IL-4 significantly enhanced IL-4 and IL-10 secretions compared with that of the vaccine control group (P<0.05).The IL-2 and IFN-γ could significantly stimulate the production of IFN-γ (P<0.01).These results indicated that IL-2 and IFN-γ of porcine could significantly enhance the immune response against FMDV respectively.
