Abstract

The aim of this study was to investigate the immunoprotective effects of recombinant Echinococcus granulosus glutathione S-transferase (rEgGST) against the development of protoscolices (PSCs), and to determine the mechanisms underlying this protection. ICR mice were subcutaneously immunized three times with rEgGST at weeks 0, 2 and 4, followed by the intraperitoneal administration of E. granulosus PSCs at week 10. Six mice in each group were sacrificed at 0, 2, 4, 6, 10, 18 and 30 weeks following the initial vaccination in order to observe the macroscopic and microscopic effects of parasite development. Various analyses were subsequently conducted, including determination of the levels of immunoglobulins (Igs) and cytokines. Significant differences were observed a number of indices of immune response following immunization with rEgGST. These included reduced cyst formation and elevated levels of IgG1, IgG2a, IgG3, IL‑2, IL‑4, IL‑10 and IFN‑γ, which indicated an increased percentage of immune helper cells. The results of the present study suggest that immunization with rEgGST in mice is able to successfully reduce the PSC‑induced formation of cysts and to stimulate an immune response, suggesting that rEgGST possesses potential value as a candidate vaccine for PSC infection.
