INTRODUCTION
Hepatitis E virus (HEV), with heightened virulence in immunocompromised individuals and pregnant women, is a pervasive threat in developing countries. A globaly available vaccine against HEV is currently lacking.
METHODS
We designed a multi-epitope vaccine based on protein ORF2 and ORF3 of HEV using immunoinformatics.
RESULTS
The vaccine comprised 23 nontoxic, nonallergenic, soluble peptides. The stability of the docked peptide vaccine-TLR3 complex was validated by molecular dynamic simulations. The induction of effective cellular and humoral immune responses by the multi-peptide vaccine was verified by simulated immunization.
DISCUSSION
These findings provide a foundation for future HEV vaccine studies.
引言
戊型肝炎病毒（HEV）在免疫功能低下的个体和孕妇中具有更高的毒力，是发展中国家普遍存在的威胁。目前全球缺乏针对HEV的可用疫苗。
方法
我们利用免疫信息学设计了一种基于HEV蛋白ORF2和ORF3的多表位疫苗。
结果
该疫苗由23种无毒、无过敏、可溶性肽组成。通过分子动力学模拟验证了对接肽疫苗-TLR3复合物的稳定性。通过模拟免疫验证了多肽疫苗诱导有效的细胞免疫和体液免疫反应。
讨论
这些发现为未来的HEV疫苗研究奠定了基础。
