Development of an effective, broadly-active and safe vaccine for protection of poultry from H5N1 highly pathogenic avian influenza viruses (HPAIVs) remains an important practical goal. In this study we used a low pathogenic wild aquatic bird virus is

Hemagglutinin (HA) of influenza virus is S-acylated with stearate at a transmembrane cysteine and with palmitate at two cytoplasmic cysteines. The amount of stearate varies from 35 (in avian strains) to 12% (in human strains), although the acylation

Influenza virus hemagglutinin spike neck architectures and interaction with model enzymes evaluated by MALDI-TOF mass spectrometry and bioinformatics tools

Interactions between model enzymes and the influenza virus hemagglutinin (HA) homotrimeric spike were addressed. We digested influenza virions (naturally occurring strains and laboratory reassortants) with bromelain or subtilisin Carlsberg and analyz

Postreassortment Changes in Influenza A Virus Hemagglutinin Restoring HA–NA Functional Match

An important function of influenza virus neuraminidase (NA) is the removal of sialic acid residues from virion components in order to prevent the aggregation of virus particles. In previous communications we have reported that reassortant viruses con

Influenza virus A (FluA) reassortants with low-functional neuraminidase (NA) of subtype N1 and hemagglutinin (HA) of subtypes H2, H3, H4, and H13 display virion aggregation and accumulate to a lower titer because sialyl residues are not completely re

Influenza virus hemagglutinin is a homotrimeric spike glycoprotein crucial for virions' attachment, membrane fusion, and assembly reactions. X-ray crystallography data are available for hemagglutinin ectodomains of various types/subtypes but not for

Intergenic HA-NA interactions in influenza A virus: postreassortment substitutions of charged amino acid in the hemagglutinin of different subtypes

Publikováno v: Virus research. 66(2)

In our previous studies influenza A virus reassortants having neuraminidase (NA) gene of A/USSR/90/77 (H1N1) strain and hemagglutinin (HA) genes of H3, H4 and H13 subtypes were shown to produce a low virus yield and to exhibit a strong tendency to vi
