| Influenza is the prototypic virus containing a class I fusion protein, hemagglutinin, that requires low pH for fusion. |
| Unfortunately, a traditional flu vaccine can protect against only flu viruses with a matching hemagglutinin protein. |
| The different subtypes and strains of influenza viruses are distinguished by the hemagglutinin and neuraminidase antigens they possess. |
| In this study we monitored membrane ionic permeability at early stages of fusion mediated by the fusogenic protein influenza hemagglutinin. |
| Most consist of a viral protein called hemagglutinin, which has the unique ability to latch onto respiratory cells and invade them. |
| Most are made of a viral protein called hemagglutinin, which can latch onto cells that the virus seeks to enter. |
