SUN Y, Xu Q, Shen Y, Liu L, et al. Naturally occurring mutations in the PA gene are key contributors to increased virulence of pandemic H1N1/09 influenza virus in mice.. J Virol. 2014.  Abstract  
submitted by kickingbird at Feb, 16, 2014 from J Virol. 2014
We examined the molecular basis of virulence of pandemic H1N1/09 influenza viruses by reverse genetics based on two H1N1/09 virus isolates (A/California/04/2009 [CA04] and A/swine/Shandong/731/2009 [SD731]) ...

TARNOW C, Engels G, Arendt A, Schwalm F, et al. TMPRSS2 is a host factor that is essential for pneumotropism and pathogenicity of H7N9 influenza A virus in mice. J Virol. 2014 Feb 12.  Abstract  
submitted by kickingbird at Feb, 16, 2014 from J Virol. 2014 Feb 12
Cleavage of the hemagglutinin (HA) by host proteases is essential for the infectivity of influenza viruses. We have analysed here the role of the serine protease TMPRSS2 activating HA in the human respiratory ...

Novel influenza A viruses of the H7N9 subtype [A(H7N9)] emerged in the spring of 2013 in China and have infected 163 people as of January 10, 2014; fifty of them died of the severe respiratory infection ...

YANG H, Chang JC, Guo Z, Carney PJ, et al. Structural stability of influenza A(H1N1)pdm09 virus hemagglutinins. J Virol. 2014 Feb 12..  Abstract  
submitted by kickingbird at Feb, 16, 2014 from J Virol. 2014 Feb 12.
The non-covalent interactions that mediate trimerization of the influenza hemagglutinin (HA) are important determinants of its biological activities. Recent studies have demonstrated that mutations in ...

submitted by kickingbird at Feb, 16, 2014 from Arch Virol. 2014 Feb 9
Both H9N2 subtype avian influenza and 2009 pandemic H1N1 viruses (pH1N1) can infect humans and pigs, which provides the opportunity for virus reassortment, leading to the genesis of new strains with potential ...
