PubMed Abstract: The influenza virus enters the host via hemagglutinin protein binding to cell surface sialic acid. Receptor-mediated endocytosis is followed by viral nucleocapsid uncoating for replication aided by the transmembrane viral M2 proton ion channel. M2 ectodomain (M2e) is a potential universal candidate for monoclonal antibody therapy owing to its conserved nature across influenza virus subtypes and its importance in viral propagation.
