Abstract
Cystic echinococcosis is a worldwide zoonotic disease, represents a threat for livestock and humans, manifests as a quiescent, subclinical and chronic hydatid cyst infection. The disease imposes high expenditures and economic losses in medical and veterinary. Prophylactic vaccination would be one of the effective preventive health care against echinococcosis. During the last decades, many studies have characterized the protective antigens of Echinococcus granulosus and their role in immunization of various animal host species. Herein, we aimed to systematically evaluate and represent the best antigens as possible vaccine candidates for cystic echinococcosis. Data were systematically searched from five databases including ProQuest, PubMed, Scopus, ScienceDirect and Web of Science, up to 1 February 2020. Two reviewers independently screened and assessed data extraction and quality assessment. A total of 47 articles were eligible for inclusion criteria in the current study. The most common antigens used for vaccination against E. granulosus were EG95 and antigen B. Freund's adjuvant and Quil A have been predominantly utilized. In addition, regarding the antigen delivery, animal models, measurement of immune responses and reduction in hydatid cyst have been discussed in the text. The data demonstrated that DNA vaccines with antigen B and recombinant protein vaccines based on EG95 antigen have the best results and elicited protective immune responses.

Abstract
The aims of the present study were to investigate the immunoprotection of recombinant Echinococcus granulosus myophilin (rEg.myophilin) against the establishment of a challenge oral infection with E. granulosus eggs, as well as to determine the mechanisms underlying this protection. Sheep were subcutaneously immunized two times with rEg.myophilin, followed by the challenge with E. granulosus eggs orally. The animals were sacrificed 44 weeks after infection and the immunoglobulin (Ig) and cytokine levels were analyzed using ELISA. The results identified significant changes in several indexes of animal immune response subsequent to immunization with rEg.myophilin. These changes included reduced number of formed cysts, as well as elevated levels of IgG, IgA and cytokines. The present data suggest that immunization with rEg.myophilin in sheep can successfully reduce the formation of cysts caused by challenge E. granulosus infection and stimulate immune response, suggesting that rEg.myophilin a has potential value as a candidate vaccine against E. granulosus.

Abstract
Background The local immune responses to chronic echinococcal infections in various organs are largely unknown. Since the liver is the most frequently involved organ in such infections in human we aimed to characterize the inflammatory as well as immune cell infiltrate around hydatid cysts in the liver and compared to common inflammatory processes of the liver. Method Surgical samples from the liver of 21 cystic echinococcosis (CE) patients were studied and the distribution of different types of inflammatory and immune cells were determined by immunohistochemistry. Furthermore, expression levels of costimulatory CTLA4, CD28, CD80 and CD86 molecules were measured at RNA level by PCR. Liver biopsy samples from patients with steatohepatitis (SH, n = 11) and chronic hepatitis (CH, n = 11) were used as non-inflammatory and chronic inflammatory controls, respectively. The composition and density of the inflammatory and immune cell infiltrates have been compared by using morphometry. Results CD3+ T cells predominated the inflammatory infiltrate in all pathological processes, while in CE samples CD20+ B cells, in CH samples CD68+ macrophages were also frequent. Both myeloperoxidase (MPO) + leukocytes and CD68+ macrophages were found to be significantly decreased in CE as compared to either SH or CH samples. Concerning T cell subtypes, only CD8+ T cells were found to be significantly decreased in SH samples. CD1a + dendritic cells were almost completely missing from CE biopsies unlike in any other sample types. There were no differences detected in the mRNA expression of costimulatory molecules except decreased expression of CD28 in CE samples. Conclusion In the hydatid lesions of the liver of chronic echinococcal infections T cell-mediated immunity seems to be impaired as compared to other types of chronic inflammatory processes, suggesting an immunosuppressive role for Echinococcus granulosus, which deserve further attentions.

Abstract
BACKGROUND Echinococcosis or hydatidosis is a chronic, zoonotic worldwide infection caused by the larval stage of the dog taeniid tapeworm Echinococcus granulosus. Vaccination has been considered as one of the ways to prevent of hydatidosis in recent decades. The aim of this study was to construct a pcDNA3.1 eukaryotic expression vector containing the subunit 8-kDa antigen B (Hyd1) of E. granulosus (G1 strain) and investigate its capability to induce protein expression in mammalian cell line, as a basis toward developing a DNA vaccine against hydatidosis. METHODS The coding sequence of HydI was amplified by PCR with the specific PCR primers from pQE/HydI, and then was sub-cloned into pcDNA3.1 plasmid as expression vector. The pcHyd1 plasmid was digested by restriction enzymes and amplified with the specific PCR primers to confirm cloning of this gene in pcDNA3 plasmid. In last step, the sub-cloned gene was expressed in mammalian cell line (NIH 3T3 cells). RESULT The subunit 8-kDa antigen B (Hyd1) was successfully sub-cloned in pcDNA3.1 and Hyd1 protein was expressed in eukaryotic cell confirmed by SDS-PAGE and Western blot. CONCLUSION Recombinant plasmid of pcDNA3.1 was successfully constructed and express of recombinant Hyd1 protein was confirmed. That is promising step for forthcoming measures on providing vaccine against human and animal hydatidosis.

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.

Dynamic changes of DC and T cell subsets in mice during Echinococcus multilocularis infection. Cent Eur J Immunol 2014; 39:19-24.

Abstract
The aim of this study was to determine the dynamic changes of dendritic cell (DC) pheno-types and T cell in response to Echinococcus multilocularis (Em) infection in BALB/c mice. Mice comprised the control and Em-infected group. At day 0, 2, 7, 30, 60, 90 and 120 after infection, the size of larval cysts, the phenotype of DC and Th in splenocytes and the expression of CD40, CD86, TLR2 and TLR4, on DCs sulfur were examined. The results show that after 60 days’ infection, larval cysts grow on the surface of liver, and they become larger over time. Compared with the control mice, MHC I and MHC II expressions on DC were significantly increased at day 7 (p < 0.05). At the same time, CD40, CD86, TLR2 and TLR4 increased rapidly, but after that they decreased gradually. At day 120, those markers were lower than in the control group. The ratio of CD4/CD8 was normal during 90 days of infection, while at day 120, a decline in CD4 T cell and increase in CD8 were foundleading to the inversion of the CD4/CD8 ratio. Our findings suggest that within the 120 days of Em infection, the major function of DC is to present antigens. Immune response is provided predominantly by Th1 cells, inducing host immune response against Em. However, after 120 days, DC matured and the function was suppressed. Furthermore, inversion of the CD4/CD8 ratio is beneficial to the growth of Em, thus favoring its immune evasion.
