Previously,it was found that several proteins of Haemonchus contortus were involved in the stimulation of the host immune ***,the information about the selection of superlative antigens with immunogenic efficacies on host DCs is *** the current study,the stimulatory effects of five recombinant proteins(elongation factor-1α,arginine kinase,ES-15,ES-24,and ADP-ribosylation factor 1) of *** on the maturation of goat monocyte-derived dendritic cells(md.DCs) were *** proteins were purified separately in *** expression and incubated with isolated goat peripheral blood mononuclear cells(PBMC).Immunofluorescence assay(IFA) results confirmed the binding of these molecules to the md.DC’s surface as compared to control *** the flow cytometry analysis,recombinant proteins induced md.DC stimulation via the up-regulation of the expression of the costimulatory molecule(CD80) and MHC-Ⅱ.Quantitative RT-PCR data showed a significant increase in the expression of specific genes of the WNT and toll-like receptor(TLR) signaling *** result of ELISA indicated the higher levels of cytokine(IL-10,IL-12,IFN-y,and TNF-α) secretion in the md.DC compared to the negative(pET-32 a His-Tag) and blank(PBS)control *** data gives valuable support in the selection of potential antigens for future studies on the immunomodulation of the host against the infection of ***.
