Influenza virus neuraminidase (na) plays an essential role in release and spread of progeny virions, following the intracellular viral replication cycle to test whether na could also facilitate virus entry into cell, we infected cultures of human airway epithelium with human and avian influenza . It is the enzyme neuraminidase, projecting form the surface of influenza virus particles, which allows the virus to leave infected cells and spread in the body antibodies which inhibit the enzyme limit the infection, but antigenic variation of the neuraminidase renders it ineffective in a vaccine.
