The global spread of highly pathogenic avian influenza virus (H5N1 subtype) has promoted efforts to develop human vaccines against potential pandemic outbreaks. However, current platforms for influenza vaccine production are cumbersome, limited in scalability and often require the handling of live infectious virus. We describe the production of(More)
BACKGROUND Influenza A viruses are of major concern for public health, causing worldwide epidemics associated with high morbidity and mortality. Vaccines are critical for protection against influenza, but given the recent emergence of new strains with pandemic potential, and some limitations of the current production systems, there is a need for new(More)
Highly pathogenic avian influenza (HPAI) viruses of the H5N1 subtype have been identified as a potential pandemic threat by the World Health Organization (WHO). Since 1997, these viruses have been spreading from Asia to Europe and Africa with increasing genetic and antigenic diversities. Vaccination is the preferred strategy for the prevention and control(More)
In 2009, a novel H1N1 swine influenza virus was isolated from infected humans in Mexico and the United States, and rapidly spread around the world. Another virus, a highly pathogenic avian influenza virus of the H5N1 subtype, identified by the World Health Organization as a potential pandemic threat in 1997, continues to be a significant risk. While(More)
BACKGROUND Influenza virus is a globally important respiratory pathogen that causes a high degree of annual morbidity and mortality. Significant antigenic drift results in emergence of new, potentially pandemic, virus variants. The best prophylactic option for controlling emerging virus strains is to manufacture and administer pandemic vaccines in(More)
Influenza is a globally important respiratory pathogen that causes a high degree of morbidity and mortality annually. Although current vaccines are effective against virus infection, new strategies need to be developed to satisfy the global demand for an influenza vaccine. To address this point, we have engineered and produced the full-length hemagglutinin(More)
The increased worldwide awareness of seasonal and pandemic influenza, including pandemic H1N1 virus, has stimulated interest in the development of economic platforms for rapid, large-scale production of safe and effective subunit vaccines. In recent years, plants have demonstrated their utility as such a platform and have been used to produce vaccine(More)
Influenza is a prevalent, highly contagious and sometimes fatal respiratory disease. Vaccination provides an effective approach to control the disease, but because of frequent changes in the structure of the major surface proteins, there is great need for a technology that permits rapid preparation of new forms of the vaccine each year in sufficient(More)
Damage to the vascular endothelium by reactive oxygen species causes many cardiovascular diseases including atherosclerosis. Such damage can be prevented by selenium (Se), which is thought to exert its actions mainly through the expression of selenoproteins. Se deficiency increased the susceptibility to tert-butylhydroperoxide (t-BuOOH) and enhanced lipid(More)
The H1N1 influenza pandemic of 2009 stimulated interest in developing safe and effective subunit influenza vaccines using rapid and cost-effective recombinant technologies that can avoid dependence on hens' eggs supply and live viruses for production. Among alternative approaches to subunit vaccine development, virus-like particles (VLPs) represent an(More)
