Hemagglutinin-based polyanhydride nanovaccines against H5N1 influenza elicit protective virus neutralizing titers and cell-mediated immunity

H5N1 avian influenza is a significant global concern with the potential to become the next pandemic threat. Recombinant subunit vaccines are an attractive alternative for pandemic vaccines compared to traditional vaccine technologies. In particular, polyanhydride nanoparticles encapsulating subunit proteins have been shown to enhance humoral and cell-mediated immunity and provide protection upo...

Nanodisc-incorporated hemagglutinin provides protective immunity against influenza virus infection.

Every year, influenza virus infection causes significant mortality and morbidity in human populations. Although egg-based inactivated viral vaccines are available, their effectiveness depends on the correct prediction of the circulating viral strains and is limited by the time constraint of the manufacturing process. Recombinant subunit vaccines are easier to manufacture with a relatively short...

Biogenesis of Influenza A Virus Hemagglutinin Cross-Protective Stem Epitopes

Antigenic variation in the globular domain of influenza A virus (IAV) hemagglutinin (HA) precludes effective immunity to this major human pathogen. Although the HA stem is highly conserved between influenza virus strains, HA stem-reactive antibodies (StRAbs) were long considered biologically inert. It is now clear, however, that StRAbs reduce viral replication in animal models and protect again...

Immunity Against Avian Influenza Viruspanax Ginseng Polysaccharide (GPS) Can Improve Immunity Against H9N2 Avian Influenza Virus in Chickens

The humoral immunization potential of panax ginseng polysaccharide (GPS) against H9N2 avian influenza virus (H9N2 AIV) in chickens was investigated. The effects of GPS treatment before and during H9N2 AIV infection were determined in chicken embryo fibroblast (CEF) by MTT (3(4, 5-dimethylthiazol-2-yl)-2, 3-diphenyl tetrazolium bromide) assays and quantitative RT-PCR analysis of MHC and cytokine...

Influenza virus hemagglutinin cleavage into HA1, HA2: no laughing matter.

What do an odd lab-derived strain of influenza, fowl plague virus, and the 1997 Hong Kong chicken flu have in common? The answer lies in how, and more specifically by what protease, the hemagglutinin protein of these various influenza strains is cleaved for viral activation. What does this have to do with the most devastating influenza virus of them all, the 1918 ‘‘Spanish’’ influenza? The conn...
