Western blot - Anti-Avian Influenza A Neuraminidase antibody (AB21304)

Expression of the H1 or N1 proteins by recombinant vaccinia viruses was detected by Western blotting. Vero cells in case of the VV-L constructs, or the avian cell line DF-1 [15] in case of MVA, were infected at a multiplicity of infection of 0.1 for 48 hours. MVA-H1-Ca or rVVL-H1-Ca infected cells were harvested by scraping or by adding trypsin. MVA-N1-Ca or rVVL-N1-Ca infected cells were harvested by scraping. Sonicated cell lysates were loaded onto 12% polyacrylamide gels and afterwards blotted on nitrocellulose membrane. To detect the H1 protein, a sheep antiserum against the A/California/7/2009 hemagglutinin (NIBSC 09/152) was used. Donkey-anti-sheep alkaline phosphatase-conjugated IgG was used as a secondary antibody. To detect the N1 protein ab21304 was utilized. Goat-anti-rabbit alkaline phosphatase-conjugated IgG was used as a secondary antibody. A whole virus vaccine H1N1 A/California/7/2009 [16] served as positive control.

補足情報

This supplementary information is collated from multiple sources and compiled automatically.

Avian Influenza A Neuraminidase sometimes called N1 or neuraminidase protein is a viral enzyme with significant mechanical functions in the life cycle of influenza viruses. This enzyme a glycoprotein with an approximate mass of 470 kDa is expressed on the surface of the influenza virus particles. Neuraminidase cleaves sialic acid residues from glycoproteins and glycolipids facilitating the release of newly formed viral particles from infected host cells. This action helps the virus to spread efficiently and infect more cells.
Biological function summary

In the influenza virus life cycle the neuraminidase protein helps in preventing viral self-aggregation and assists in viral movement within the host. It is not part of a complex but functions in coordination with the hemagglutinin protein. Both neuraminidase and hemagglutinin are found on the viral envelope and play important roles in the viral infection process with hemagglutinin binding to host cell receptors and neuraminidase aiding in viral egress.

Pathways

Neuraminidase activity is integral to the sialic acid metabolic pathway ensuring the process of viral particle release is efficient. Neuraminidase works alongside hemagglutinin in the infection cycle with the two proteins together maintaining equilibrium necessary for efficient viral replication and dissemination. Additionally neuraminidase is involved in the neuraminidase inhibitor pathway which is targeted for antiviral drug development that block its function to prevent virus spread.

Avian influenza neuraminidase is most associated with influenza infections specifically avian influenza affecting both birds and occasionally humans. Antigenic variation in neuraminidase leads to the emergence of new strains complicating vaccine development and treatment strategies. Neuraminidase also plays a role in swine flu pathogenesis interacting with host proteins and hemagglutinin to mediate infection. Efforts to create avian antibodies target neuraminidase aiming to develop therapies that can either prevent or limit the spread of these infections.

ターゲットの情報

Catalyzes the removal of terminal sialic acid residues from viral and cellular glycoconjugates. Cleaves off the terminal sialic acids on the glycosylated HA during virus budding to facilitate virus release. Additionally helps virus spread through the circulation by further removing sialic acids from the cell surface. These cleavages prevent self-aggregation and ensure the efficient spread of the progeny virus from cell to cell. Otherwise, infection would be limited to one round of replication. Described as a receptor-destroying enzyme because it cleaves a terminal sialic acid from the cellular receptors. May facilitate viral invasion of the upper airways by cleaving the sialic acid moieties on the mucin of the airway epithelial cells. Likely to plays a role in the budding process through its association with lipid rafts during intracellular transport. May additionally display a raft-association independent effect on budding. Plays a role in the determination of host range restriction on replication and virulence. Sialidase activity in late endosome/lysosome traffic seems to enhance virus replication.
