Protection against Multiple Subtypes of Influenza Viruses by Virus-Like Particle Vaccines Based on a Hemagglutinin Conserved Epitope
We selected the conserved sequence in the stalk region of influenza virus hemagglutinin (HA) trimmer, the long alpha helix (LAH), as the vaccine candidate sequence, and inserted it into the major immunodominant region (MIR) of hepatitis B virus core protein (HBc), and, by using the E. coli expression system, we prepared a recombinant protein vaccine LAH-HBc in the form of virus-like particles (...
متن کاملDesigning of A Multi-epitope Recombinant Protein, Consisting of Several Conserved Epitopes from Hemagglutinin Protein of the H1N1 and H5N1 Strains of Influenza Virus by Immunoinformatics Approaches
Introduction: According to marked advances in bioinformatics studies, development of influenza vaccines has been greatly modified in many studies. In this study, we have designed a multi-epitope recombinant protein, consisting of several conserved epitopes from Hemagglutinin protein of the H1N1 and H5N1 strains of Influenza virus by immunoinformatics approaches. Materials and Methods: The regis...
متن کاملGlobular Head-Displayed Conserved Influenza H1 Hemagglutinin Stalk Epitopes Confer Protection against Heterologous H1N1 Virus.
Significant genetic variability in the head region of the influenza A hemagglutinin, the main target of current vaccines, makes it challenging to develop a long-lived seasonal influenza prophylaxis. Vaccines based on the conserved hemagglutinin stalk domain might provide broader cross-reactive immunity. However, this region of the hemagglutinin is immunosubdominant to the head region. Peptide-b...
متن کاملProtection against Multiple Influenza A Virus Strains Induced by Candidate Recombinant Vaccine Based on Heterologous M2e Peptides Linked to Flagellin
Matrix 2 protein ectodomain (M2e) is considered a promising candidate for a broadly protective influenza vaccine. M2e-based vaccines against human influenza A provide only partial protection against avian influenza viruses because of differences in the M2e sequences. In this work, we evaluated the possibility of obtaining equal protection and immune response by using recombinant protein on the ...
متن کاملPotential recombinant vaccine against influenza A virus based on M2e displayed on nodaviral capsid nanoparticles
Influenza A virus poses a major threat to human health, causing outbreaks from time to time. Currently available vaccines employ inactivated viruses of different strains to provide protection against influenza virus infection. However, high mutation rates of influenza virus hemagglutinin (H) and neuraminidase (N) glycoproteins give rise to vaccine escape mutants. Thus, an effective vaccine prov...
