Experiments in mice revealed that the 1918 and 2009 pandemic flu viruses have certain similarities in a surface protein, hemagglutinin, which is instrumental in infecting cells. However, unlike seasonal viruses, which have sugar glycan molecules attached to hemagglutinin, they lack these sugar molecules. The glycans, which protect the virus from antibody detection, are a key feature adopted as a pandemic virus evolves into a seasonal strain.
