Universal type/subtype-specific antibodies for quantitative analyses of neuraminidase in trivalent influenza vaccines

Scientific Reports, 2018
Both influenza viral hemagglutinin and neuraminidase can induce protective immune responses in humans. Although the viral hemagglutinin antigens have been quantified in influenza vaccines, the amounts of neuraminidase remain undetermined.

Homology modelling and insilico analysis of neuraminidase protein in H1N1 Influenza A virus

Brazilian Archives of Biology and Technology, 2011
In this work, modelling of Neuraminidase protein of Influenza A virus (A/Himeji/1/2009(H1N1)) neuraminidase (NA) protein was done using Modeller 9V2.

Cross-protection against European swine influenza viruses in the context of infection immunity against the 2009 pandemic H1N1 virus : studies in the pig model of influenza [PDF]

, 2015
Pigs are natural hosts for the same influenza virus subtypes as humans and are a valuable model for cross-protection studies with influenza. In this study, we have used the pig model to examine the extent of virological protection between a) the 2009 ...

Influenza Hemagglutinin and Neuraminidase: Yin–Yang Proteins Coevolving to Thwart Immunity

Viruses, 2019
Influenza A virions possess two surface glycoproteins—the hemagglutinin (HA) and neuraminidase (NA)—which exert opposite functions. HA attaches virions to cells by binding to terminal sialic acid residues on glycoproteins/glycolipids to initiate the ...

Microglia activated by microbial neuraminidase contributes to ependymal cell death

Fluids and Barriers of the CNS, 2021
The administration of microbial neuraminidase into the brain ventricular cavities of rodents represents a model of acute aseptic neuroinflammation. Ependymal cell death and hydrocephalus are unique features of this model.

Alterations of membrane curvature during influenza virus budding [PDF]

, 2014
Influenza A virus belongs to the Orthomyxoviridae family. It is an enveloped virus that contains a segmented and negative-sense RNA genome. Influenza A viruses cause annual epidemics and occasional major pandemics, are a major cause of morbidity and ...

Characterization of the hemagglutinin receptor specificity and neuraminidase substrate specificity of clinical isolates of human influenza A viruses

Memorias do Instituto Oswaldo Cruz, 1994
Six clinical isolates of influenza A viruses were examined for hemagglutinin receptor specificity and neuraminidase substrate specificity. All of the viral isolates minimally passaged in mammalian cells demonstrated preferential agglutination of human ...

Self-amplifying mRNA bicistronic influenza vaccines raise cross-reactive immune responses in mice and prevent infection in ferrets

Molecular Therapy: Methods & Clinical Development, 2022
Vaccines are the primary intervention against influenza. Currently licensed inactivated vaccines focus immunity on viral hemagglutinin (HA). Self-amplifying mRNA (sa-mRNA) vaccines offer an opportunity to generate immunity to multiple viral proteins ...

Ferrets exclusively synthesize Neu5Ac and express naturally humanized influenza A virus receptors [PDF]

, 2014
Mammals express the sialic acids ​N-acetylneuraminic acid (​Neu5Ac) and ​N-glycolylneuraminic acid (​Neu5Gc) on cell surfaces, where they act as receptors for pathogens, including influenza A virus (IAV). ​Neu5Gc is synthesized from ​Neu5Ac by the enzyme

Influenza A Virus Hemagglutinin–Neuraminidase–Receptor Balance: Preserving Virus Motility

Trends in Microbiology, 2019
Influenza A viruses (IAVs) occasionally cross the species barrier and adapt to novel host species. This requires readjustment of the functional balance of the sialic acid receptor-binding hemagglutinin (HA) and the receptor-destroying neuraminidase (NA ...
