We developed a novel immunomagnetic bead ELISA based on IgY (egg yolk immunoglobulin) for detection of circulating antigen (CA) in sera of mice infected with Schistosoma japonicum. The assay involved the use of chicken polyclonal antibodies IgY against soluble egg antigens (SEA) of S. japonicum as a capture antibody and anti-SEA mouse monoclonal antibody(More)
Bone morphogenetic proteins (BMPs) are known to play an important role in the regulation of cell proliferation, survival, differentiation and apoptosis in many vertebrates and invertebrates through the TGF-β signaling pathway. Although the TGF-β signaling pathway exists in schistosomes, BMP homologue, a ligand of TGF-β in Schistosoma japonicum, has not yet(More)
In a previous study we demonstrated that CD4(+)CD25(+) regulatory T cells (Tregs) contributed to the escape of Schistosoma japonicum (S. japonicum) from the host's immune responses. In this paper, we studied the effect of cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) on CD4(+)CD25(+) Tregs in murine Schistosomiasis japonica and its corresponding role(More)
It has been known that parasites developed sophisticated strategies to escape from the host immune assault. More recently, one strategy to induce immune evasion involved CD4+CD25+ regulatory T cells (Tregs). Mice were infected with Schistosoma japonicum cercariae and then injected intraperitoneally with anti-CD25 monoclonal antibody (anti-CD25 mAb). The(More)
The effect of anti-CD25 monoclonal antibody (anti-CD25 mAb) on the protection efficacy of Schistosoma japonicum 26 kDa GST (glutathione-S-transferase) vaccine was evaluated. Mice were immunized with GST before infection with S. japonicum cercariae and then injected with anti-CD25 mAb. The worm reduction rate was promoted from 24.18% in mice with GST(More)
The specific molecular targets of schistosomula have been investigated for being new vaccine candidates. The mechanism of the growth and development of the skin-stage, lung-stage and hepatic schistosomula may be related to the immune regulation, signal transduction, sex-differentiation and apoptosis. Actin et al are important molecules which related to the(More)
