Although the new virus contains pieces from a variety of human and animal flu lineages , it retains the hemagglutinin protein-the h1-from the classical swine strain .
尽管新病毒含有不同的人类和动物流感基因片段,它仍然保留着来自于猪流感病毒的血凝素(h1)。
Influenza infection begins when hemagglutinin binds to receptors on the host cell .
当血凝素结合到宿主细胞受体上时,流感病毒的感染就开始了。
Finally , they spliced the hemagglutinin gene into a common-cold virus and used that to make a vaccine .
最后他们将红血球凝集素基因与普通流感病毒融合,并用其生产疫苗。
They designed a piece of mrna encoding the hemagglutinin of the influenza strain h1n1 .
他们设计了h1n1流感病毒毒株编码血凝素的一个mrna片段。
Now , most flu vaccines consist of hemagglutinin and neuraminidase , the two proteins covering the surface of the virus .
