Expression of Polar Tube Protein 1 (NbPTP1) from Nosema bombycis in Drosophila S2 cell lines and its glycosylation / 生物工程学报

The polar tube protein is the major component of polar tube, and can specifically locate on the polar tube of microsporidia and plays an important role in invasion host cell. In this study, we analyzed the potential O- and Nglycosylation sites in polar tube protein 1 from Nosema bombycis. NbPTP1 was successfully cloned to eukaryotic expression vector pMT/Bip/V5-His A, involved V5 and His tags. After transfection, NbPTP1 gene could be efficiently expressed in Drosophila S2 cells. In addition, Lectin blotting and beta elimination analysis showed that NbPTP1 expressed in Drosophila S2 cells was O-glycosylation. These studies provided a basis for understanding the relationship between glycosylation and function of NbPTP1, helped us to reveal the infection mechanism of microsporidia and established effective diagnosis and prevention methods for microsporidia.

Research Progress on the Technology of Microsporidian Detection / 中国寄生虫学与寄生虫病杂志

The microsporidia are obligate intracellular eukaryotic parasites.They have been paid more attention as being the emerging pathogen of human, so it is important to control microsporidiosis using fast and precise detecting technology.In order to provide a reference for controlling microsporidian infection effectively, this paper reviews the progress of studying on the detecting technology from the microscopic staining methods, immunological and molecular biology.
