A panel of influenza A viruses expressing chimeric hemagglutinins (cHA) with intragroup or intergroup head/stalk combinations was generated. Viruses were characterized for growth kinetics and preservation of stalk epitopes. With a few notable exceptions, cHA viruses behaved similarly to wild-type viruses and maintained stalk epitopes, which indicated their potential as vaccine candidates to induce stalk-specific antibodies.
构建了一组表达具有组内或组间头部/茎部组合的嵌合血凝素(cHA)的甲型流感病毒。对病毒的生长动力学和茎部表位的保留情况进行了表征。除了一些明显的例外,cHA病毒的行为与野生型病毒相似,并保留了茎部表位,这表明它们作为诱导茎部特异性抗体的候选疫苗具有潜力。
