Over Expression of Influenza Virus M2 Protein in Prokaryotic System
Background and Aims: Influenza A virus of Orthomyxoviridae family is able to create pandemic influenza. Vaccination is the most effective way to prevent influenza virus infection. Matrix protein 2 (M2) is a homotetramer ion channel with 97 amino acids length and highly conserved among influenza viruses and is considered for development of a universal influenza vaccine. Materials and Methods: We...
متن کاملInteractions of misfolded influenza virus hemagglutinin with binding protein (BiP)
We have characterized the association between the binding protein, BiP (also known as GRP 78), and misfolded forms of the influenza virus hemagglutinin precursor, HA0. BiP is a heat-shock-related protein that binds to unassembled immunoglobulin heavy chain and to a variety of misfolded proteins in the lumen of the ER. A small fraction (5-10%) of newly synthesized HA0 in CV-1 cells was found to ...
متن کاملInfluenza B virus with modified hemagglutinin cleavage site as a novel attenuated live vaccine.
BACKGROUND Both pandemic and interpandemic influenza is associated with high morbidity and mortality worldwide. Seasonal epidemics are caused by both influenza A and B virus strains that cocirculate with varying predominance and may give rise to severe illness equally. According to World Health Organization recommendations, current annual vaccines are composed of 2 type A and 1 type B virus-spe...
متن کاملMechanisms of Hemagglutinin Targeted Influenza Virus Neutralization
Human monoclonal antibodies have been identified which neutralize broad spectra of influenza A or B viruses. Here, we dissect the mechanisms by which such antibodies interfere with infectivity. We distinguish four mechanisms that link the conserved hemagglutinin (HA) epitopes of broadly neutralizing antibodies to critical processes in the viral life cycle. HA-stem binding antibodies can act int...
متن کاملAntigenic determinants in influenza virus hemagglutinin.
Three antigenic determinants were revealed in H3 hemagglutinin of influenza A viruses isolated from 1968 to 1975. One of them was common for all viruses, and two others specified differences between the viruses possessing H3 hemagglutinin.
