Membrane fusion activity of reconstituted vesicles of influenza virus hemagglutinin glycoproteins
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1983Reconstituted vesicles of hemagglutinin glycoproteins into egg yolk phosphatidylcholine/spin-labeled phosphatidylcholine/cholesterol (molar ratio 1.6:0.4:1) were prepared by dialysis. Preparations at appropriate protein-to-lipid ratios (1:44 and 1:105 mol/mol) contained vesicles with a diameter of 100-300 nm and a high density of spikes on the surface.

An H5N1 avian influenza virus (AIV) hemagglutinin (HA) protein pseudotyped lentivirus, HIV/H5-HA, was generated, characterized in vitro and evaluated for its ability to induce protective immunity against virulent wild type AIV in mice. The HIV/H5-HA virus was able to infect 293T, BHK, Vero, PK-15, MDCK cells but not IBRS-2 cells and therefore ...

Influenza D virus (IDV) is a new member of influenza virus that uses cattle as the primary reservoir and infects multiple agricultural animals. Similar to influenza C virus (ICV), IDV also has seven segments in its genome and has only one major surface glycoprotein, called the hemagglutinin-esterase-fusion (HEF) protein, for receptor-binding, receptor ...

We have analyzed the mechanism by which the matrix (M1) protein associates with cellular membranes during influenza A virus assembly. Interaction of the M1 protein with the viral hemagglutinin (HA) or neuraminidase (NA) glycoprotein was extensively analyzed by using wild-type and transfectant influenza viruses as well as recombinant vaccinia viruses ...

A cDNA copy of RNA segment 4 of influenza C/Cal/78 virus was cloned into an SV40 vector and expressed in CV-1 cells. The gene product expressed from the SV40 recombinant virus was immunoprecipitated by monoclonal antibodies directed against the influenza C virus glycoprotein.

Influenza vaccines represent the most effective preventive strategy to control influenza virus infections; however, adaptive mutations frequently occur in the hemagglutinin (HA) glycoprotein during the preparation of candidate vaccine virus and production of vaccine in embryonated eggs.

Abstract The effect of the host cell and virus strain on the glycosylation of influenza A virus hemagglutinin glycoproteins was investigated by analysis of Pronase-digested glycopeptides labeled with radioactive sugar precursors. When influenza A/WSN virus was grown in MDBK cells, HA 1 contained both complex galactose-containing (type I) and mannose-

We used monoclonal antibodies that recognize monomeric and/or trimeric forms of the influenza virus hemagglutinin (HA) to study biosynthesis of this integral membrane protein in influenza virus-infected cells. We find the following: First, the globular head of the HA folds into its mature conformation in the endoplasmic reticulum prior to the assembly ...

Aim: S16, a monoclonal antibody against the hemagglutinin-esterase fusion (HEF) glycoprotein of influenza C virus, reacts with SV40 large T antigen (LT) and a host cellular component(s). The aim is to determine the location of S16 linear epitope on LT and the amino acid sequence of S16 epitope. Materials & methods: BHK-21 cells expressing wild-type and

We reported previously that monoclonal antibody S16, which had been raised against the hemagglutinin-esterase (HE) glycoprotein of influenza C/Ann Arbor/1/50 (AA/50) virus, recognizes a linear epitope present on the HE molecules of all influenza C viruses examined except for viruses belonging to a lineage represented by Aichi/1/81 (AI/81).
