Identification of differentially expressed proteins between the male and female worm of Schistosoma japonicum may provide new insights into the development of schistosomes, especially the molecular mechanism of female worm maturation induced by the male worm after pairing. Comparative two-dimensional gel electrophoresis (2-DE) and mass spectrometry were(More)
The Wnt signaling pathway is an evolutionarily conserved signal transduction pathway used extensively during animal development. We aim, by increasing our understanding of the Wnt signaling pathway, to find a key gene or protein present in schistosomes that can be developed into vaccine candidate or drug target. We therefore isolated the Wnt4 gene from(More)
OBJECTIVE To clone, express and characterize a tegument protein gene of Schistosoma japonicum (Sj29) , and investigate the immune protection of the recombinant protein against S. japonicum in mice. METHODS The gene coding for Sj29 protein was amplified by PCR, and the sequence was analyzed by bioinformatics tools. Partial fragment of Sj29 gene was(More)
Cellular immunity plays an important role in defense against diseases, such as pathogenic infection, autoimmunity and tumor. With the progress of molecular immunology, mechanisms of T cellular immunity, and the T cell epitopes and functional genomics, studies on the prediction based on data-derived for T cell epitopes has been highlighted, and could be one(More)
OBJECTIVE Current advances in reverse vaccinology based on the principle of "sequence-structure-function" and such integrated platform technologies as immunoinformatics, computer-aid design, and various high-throughput omics (including genomics, transcriptomics and proteomics) may pave a new way for the discovery of candidate vaccine molecules against(More)
Based on the phenomenon of the natural anti-schistosomiasis in Microtus fortis, the sera from normal Microtus fortis were employed to immunoscreen the cDNA library of adult Schistosoma japonicum (Chinese strain), two positive clones were obtained, RACE technique was further applied to amplify one of the clones, and a cDNA fragment with an ORF was(More)
OBJECTIVE To get the characteristic differentially expressed genes of Schistosoma japonicum from three important reservoir hosts: yellow cattle, water buffalo and goat, so as to find the genetic markers to identify the various sources of the parasite reservoir hosts. METHODS The 49 d worms were collected from artificially infected animals, and the total(More)
The cDNA fragments of interest were amplified using Sj lambda ZipLox library as the templates by PCR and then cloned into a eukaryotic expression vector p-CMV-GH; A small number of DNA fragments inserted in the recombinants was identified by restriction cleavage, EST sequencing and bioinformatical analysis; mice were injected intramuscularly with the(More)
OBJECTIVE To understand the endemic situation dynamics of schistosomiasis in domestic animals (mainly bovine) in mountainous endemic regions, so as to provide the reference for evaluating the control effect and improving control strategy. METHODS Two representative pilots (Renmei and Dacang) in mountainous schistosomiasis endemic regions were selected for(More)
Wnt proteins together with their downstream effectors forms a set of important signal pathways. The Wnt signal pathway is important in a wide variety of development processes including cell growth, cell differentiation, cell polarity and apoptosis. Wnt4 is a key regulator of gonadal differentiation in humans and mice, playing a pivotal role in early(More)
