Influenza hemagglutinin drives viral entry via two sequential intramembrane mechanisms [PDF]
Proceedings of the National Academy of Sciences, 2020 AbstractEnveloped viruses enter cells via a process of membrane fusion between the viral envelope and a cellular membrane. For influenza virus, mutational data have shown that the membrane-inserted portions of the hemagglutinin protein play a critical role in achieving fusion.

One-way trip: Influenza virus' adaptation to gallinaceous poultry may limit its pandemic potential [PDF]
, 2014 We hypothesise that some influenza virus adaptations to poultry may explain why the barrier for human-to-human transmission is not easily overcome once the virus has crossed from wild birds to chickens.

Potent Anti-Influenza Activity of Cyanovirin-N and Interactions with Viral Hemagglutinin [PDF]
Antimicrobial Agents and Chemotherapy, 2003 ABSTRACT The novel antiviral protein cyanovirin-N (CV-N) was initially discovered based on its potent activity against the human immunodeficiency virus (HIV). Subsequent studies identified the HIV envelope glycoproteins gp120 and gp41 as molecular targets of CV-N.

The inducible amphisome isolates viral hemagglutinin and defends against influenza A virus infection [PDF]
Nature Communications, 2020 AbstractThe emergence of drug-resistant influenza type A viruses (IAVs) necessitates the development of novel anti-IAV agents. Here, we target the IAV hemagglutinin (HA) protein using multivalent peptide library screens and identify PVF-tet, a peptide-based HA inhibitor.

The production and development of H7 Influenza virus pseudotypes for the study of humoral responses against avian viruses [PDF]
, 2013 In recent years, high pathogenicity avian influenza (HPAI) virus, H5N1, low pathogenicity avian influenza (LPAI) virus, H9N2, and both HPAI and LPAI H7 viruses have proved devastating for the affected economies reliant on poultry industry, and have posed

Glycan receptor specificity as a useful tool for characterization and surveillance of influenza A virus [PDF]
, 2014 Influenza A viruses are rapidly evolving pathogens with the potential for novel strains to emerge and result in pandemic outbreaks in humans. Some avian-adapted subtypes have acquired the ability to bind to human glycan receptors and cause severe ...

An Open Receptor-Binding Cavity of Hemagglutinin-Esterase-Fusion Glycoprotein from Newly-Identified Influenza D Virus: Basis for Its Broad Cell Tropism. [PDF]
, 2016 Influenza viruses cause seasonal flu each year and pandemics or epidemic sporadically, posing a major threat to public health. Recently, a new influenza D virus (IDV) was isolated from pigs and cattle. Here, we reveal that the IDV utilizes 9-O-acetylated

Cross-protection between antigenically distinct H1N1 swine influenza viruses from Europe and North America [PDF]
, 2011 Background An avian-like H1N1 swine influenza virus (SIV) is enzootic in swine populations of Western Europe. The virus is antigenically distinct from H1N1 SIVs in North America that have a classical swine virus-lineage H1 hemagglutinin, as does the ...
