"This is because influenza viruses that circulate in human and animal populations mutate two key viral surface proteins, haemagglutinin (HA) and neuraminidase (NA), thus allowing them to escape from protective antibodies produced through natural infection or vaccination," Pleass added.

NKp46 and NKp44 detect the terminal N-acetylneuraminic acid residues (sialic acids) in sendai virus neuraminidase and influenza virus haemagglutinin. NKp44 detects cell-free mycobacteria and HIVgp41 [8].
H1N1 virus possesses haemagglutinin, the antigenic surface protein which mediates the entry of virus in to host cell and this is the most important antigen against which neutralising antibodies are directed.
In our study, we cloned the codon-optimized gene encoding haemagglutinin of the H5N1 influenza virus and expressed it intracellularly using the nisin-controlled gene expression (NICE[R]) system in L.
