H7N9 Influenza Pseudovirus

Comprehensive Neutralization Assay Solutions for Advancing Influenza Research

H7N9 pseudovirus Advantages

We produce a pseudovirus pseudotyped exclusively with the hemagglutinin protein of the influenza strain A/Shanghai/4664T/2013 (H7N9) (GenBank: KC853228.1), which was responsible for the outbreak in Shanghai in 2013. These pseudoviruses carry a modified genome that expresses a luciferase or a GFP reporter gene.

H7N9 Influenza Virus Background

The H7N9 influenza virus is an avian subtype of the influenza A virus, known for its low pathogenicity in birds but significant virulence in humans. Like other influenza A viruses, H7N9 possesses an enveloped structure and a segmented, single-stranded negative-sense RNA genome composed of eight segments, each ranging from 890 to 2,341 nucleotides. These segments encode essential proteins involved in viral entry, replication, and assembly. The hemagglutinin (HA) of H7N9 binds to α2,3- and α2,6-linked sialic acid receptors, enabling infection of both avian and human epithelial cells. Viral entry occurs through clathrin-mediated endocytosis, followed by membrane fusion and release of viral RNA into the host nucleus. Although asymptomatic in poultry, H7N9 has caused several human outbreaks with high case-fatality rates, particularly in China. Its capacity for reassortment and silent transmission in birds highlights its pandemic potential and the urgent need for surveillance and preparedness strategies.

H7N9 Pseudovirus in Publications

The increasing number of human infections caused by avian influenza A (H7N9) viruses has intensified the need for the development of effective vaccines and antiviral strategies. The pseudovirus neutralization assay, which does not require the use of infectious viruses and can be conducted outside biosafety level 3 facilities, provides a safe and efficient platform for evaluating neutralizing monoclonal antibodies (mAbs) and antiviral compounds targeting the hemagglutinin (HA) of H7N9 viruses.
