Abstract: The bioinformatics software was used to predict the B cell and T cell epitopes of Toxoplasma gondii microneme 16 (TgMIC16) followed by epitopes display on the yeast of Saccharomyces cerevisiae.B and T cell epitopes of TgMIC16 were predicted by DNAStar and IEDB,and software of SYFPEITHI and BIMAS,respectively.According to the predicted results,the antigenic epitope region was expressed with pCTCON2/EBY100 display system.The expression protein was detected by indirect immunofluorescence (IFA) and flow cytometry.Results showed that there were potential B/T cell epitopes in TgMIC16 and concentrated in the aa343-625 region.The epitope region was successfully displayed on the surface of yeast cells,and the optimal induction time was 24 hours.The study would lay the foundation for the development and efficacy evaluation of the yeast carrier vaccine in the further research.
