以计算方式优化的H3N2、H2N2和B型流感病毒的广泛反应性抗原
摘要：
本文描述了用于引起针对流感病毒分离株的广泛反应性免疫应答的优化的H3N2、H2N2和B型流感HA多肽的产生。基于H3N2、H2N2和B型流感分离株，通过一系列的HA蛋白比对和随后的共有序列产生，开发了优化的HA多肽。本文提供了优化的H3N2、H2N2和B型流感HA多肽以及包含所述HA多肽的组合物、融合蛋白和VLP。本文还提供了编码所述HA多肽的密码子优化的核酸序列。本公开内容还提供了在受试者中引起针对流感病毒的免疫应答的方法。
摘要（英）：

Described herein is the generation of optimized H3N2, H2N2 and B influenza HA polypeptides for eliciting a broadly reactive immune response to influenza virus isolates. The optimized HA polypeptides were developed through a series of HA protein alignments, and subsequent generation of consensus sequences, based on H3N2, H2N2 and B influenza isolates. Provided herein are optimized H3N2, H2N2 and B influenza HA polypeptides, and compositions, fusion proteins and VLPs comprising the HA polypeptides. Further provided are codon-optimized nucleic acid sequences encoding the HA polypeptides. Methods of eliciting an immune response against influenza virus in a subject are also provided by the present disclosure.
