Abstract

Background: Cystic echinococcosis or hydatid disease is a widely endemic helminthic zoonotic disease caused by infection with metacestodes the larval stage of the tapeworm ECHINOCOCCUS GRANULOSUS. P-29, a 29-kDa antigen from E. granulosus, is a protoscolex specific component. The immunologic cross reactivity between P-29 and a major diagnostic antigen of E. granulosus (Ag5) indicated that P-29 might be another useful antigen of E. granulosus to be used in diagnosis or in multi epitope vaccines to prevent secondary echinococcosis. In this study, the peptide epitope regions after the identification and synthesis were evaluated in order to determine the effect of stimulating an immune response in a mouse model.Methods: In this study, the p29 antigen epitope regions of the parasite ECHINOCOCCUS GRANULOSUS detected by the IEDB Bioinformatics software and a 8 amino acids sequence were synthesized. BALB/c mice were immunized subcutaneously three times with two weeks interval. Fourteen days after last immunization spleen tissues were extracted and splenocytes were cultured in presence of antigen for 72 hours. Supernatants were collected and used for CYTOKINE ASSAY by Quantikine ELISA kit.Results: Sandwich ELISA results were analyzed and showed significant difference in IFN-γ but no significant differences observed in levels of two cytokines IL-4, IL-10, between immunized and control groups.Conclusion: This study has assessed the effect of SYNTHETIC PEPTIDE EGP-29aa134-142 on the immune response and our results showed that the peptide can increase IFN-γ and therefore induce activation of innate Immunity as well as CTL and Th1 response.
