Invasion of Influenza A

Abnova April E-Newsletter
New Discoveries on Influenza A Viruses (IAVs)
  • Facilitated by high mutation rate of the viral genome and polymerase, IAVs can cause annual epidemics of approximately 500,000 deaths per year and the function interplay between hemagglutinin and neuraminidase glycoprotein characterizes the pathogenic profile of each viral subtype. (Lancet Infect Dis, 2014)
  • IAVs, mimicked as misfolded protein aggregates, carry unanchored ubiquitin chains to exploit host cell’s aggresome processing machinery for efficient IAV entry and capsid dissociation. (Science, 2014)
  • NiPT5, as a potent anti-IAV agent, can suppress the transcription, translation of vRNA and the synthesis of nucleoprotein to impede the early phase of viral replication. (Scientific Reports, 2015)

Newly Cited Antibody
Influenza A virus nucleoprotein monoclonal antibody, clone InA108
(MAB1272)

Belardo, G., et al. investigated the anti-influenza activity by using combination therapy of NTZ with neuraminidase inhibitors against broad range of Influenza A viruses and found positive outcome showing synergistic effect. Abnova’s anti-nucleoprotein monoclonal antibody was used in this study for the detection of viral replication via immunocytochemical staining. (Antimicrob. Agents Chemother., 2014)
