All the time, echinococcosis is a global zoonotic disease which seriously endangers public health all over the world. In order to speed up the development process of anti- vaccine, at the same time, it can also save economic cost. In this study, immunoinformatics tools and molecular docking methods were used to predict and screen the antigen epitopes of , to design a multi-epitope vaccine containing B- and T-cell epitopes. The multi-epitope vaccine could activate B lymphocytes to produce specific antibodies theoretically, which could protect the human body against infection. It also could activate T lymphocytes and clear the infected parasites in the body. In this study, four CD8 T-cell epitopes, three CD4 T-cell epitopes and four B-cell epitopes of Protein EgTeg were identified by immunoinformatics methods. Meanwhile, three CD8 T-cell epitopes, two CD4 T-cell epitopes and four B-cell epitopes of Protein EgFABP1 were identified. We constructed the multi-epitope vaccine using linker proteins. The study based on the traditional methods of antigen epitope prediction, further optimized the prediction results combined with molecular docking technology and improved the precision and accuracy of the results. Finally, and experiments had verified that the vaccine designed in this study had good antigenicity and immunogenicity.
棘球蚴病一直是一种全球性的人畜共患疾病,严重威胁着全世界的公共卫生。为了加快疫苗的研发进程,同时也可以节省经济成本。本研究运用免疫信息学工具和分子对接方法预测和筛选抗原表位,设计含有 B 细胞和 T 细胞表位的多表位疫苗。多表位疫苗理论上可以激活 B 淋巴细胞产生特异性抗体,从而保护人体免受 感染。它还可以激活 T 淋巴细胞并清除体内感染的寄生虫。本研究通过免疫信息学方法鉴定了蛋白 EgTeg 的四个 CD8 T 细胞表位、三个 CD4 T 细胞表位和四个 B 细胞表位。同时,鉴定了蛋白 EgFABP1 的三个 CD8 T 细胞表位、两个 CD4 T 细胞表位和四个 B 细胞表位。我们使用连接蛋白构建了多表位疫苗。本研究在抗原表位预测的传统方法的基础上,结合分子对接技术对预测结果进行了进一步优化,提高了结果的精度和准确性。最后,和 实验验证了本研究设计的疫苗具有良好的抗原性和免疫原性。
