NS1 Influenza Protein - Pathogenicity
... The fact that NS1 is involved in the pathogenicity of influenza A viruses makes it a good target to attenuate these viruses ... Several studies demonstrated that influenza viruses with partial deletions in NS1 proteins are attenuated and do not cause disease, but induce a protective immune ... Although it had been known for more than a decade that influenza viruses with partial deletions in NS1 proteins were attenuated, all but one NS1 truncation variants of ...
H5N1 Genetic Structure - Surface Encoding Gene Segments
... for hemagglutinin which is an antigenic glycoprotein found on the surface of the influenza viruses and is responsible for binding the virus to the ... Hemagglutinin forms spikes at the surface of flu viruses that function to attach viruses to cells ... One genetic factor in distinguishing between human flu viruses and avian flu viruses is that "avian influenza HA bind alpha 2-3 sialic acid receptors while human influenza HA bind alpha 2-6 sialic acid ...
Human Mortality From H5N1 - Predicting Pandemic Mortality Rate - Genetic Factors
... H5N1 may cause more than one influenza pandemic as it is expected to continue mutating in birds regardless of whether humans develop herd immunity to a future pandemic strain ... Influenza pandemics from its genetic offspring may include influenza A virus subtypes other than H5N1 ... analysis of the H5N1 virus shows that influenza pandemics from its genetic offspring can easily be far more lethal than the Spanish Flu pandemic, planning for a ...
H5N1 Genetic Structure
... H5N1 is an Influenza A virus subtype ... of highly pathogenic varieties, but all currently belonging to genotype Z of avian influenza virus H5N1 ... The "H5N1 viruses from human infections and the closely related avian viruses isolated in 2004 and 2005 belong to a single genotype, often referred to as ...
H5N1 - Genetics - Genetic Structure and Related Subtypes
... H5N1 is a subtype of the species Influenza A virus of the Influenzavirus A genus of the Orthomyxoviridae family ... Like all other influenza A subtypes, the H5N1 subtype is an RNA virus ... for hemagglutinin, an antigenic glycoprotein found on the surface of the influenza viruses and is responsible for binding the virus to the cell that is being infected ...
