One-way trip: Influenza virus' adaptation to gallinaceous poultry may limit its pandemic potential [PDF]
We hypothesise that some influenza virus adaptations to poultry may explain why the barrier for human-to-human transmission is not easily overcome once the virus has crossed from wild birds to chickens.

Influenza A Strain-Dependent Pathogenesis in Fatal H1N1 and H5N1 Subtype Infections of Mice
To determine if fatal infections caused by different highly virulent influenza A viruses share the same pathogenesis, we compared 2 different influenza A virus subtypes, H1N1 and H5N1. The subtypes, which had shown no pathogenicity in laboratory mice, were forced to evolve by serial passaging.

Complement-Independent Modulation of Influenza A Virus Infection by Factor H
The complement system is an ancient innate immune defense mechanism that can recognize molecular patterns on the invading pathogens. Factor H, as an inhibitor of the alternative pathway, down-regulates complement activation on the host cell surface ...

Pandemic Paradox: Early Life H2N2 Pandemic Influenza Infection Enhanced Susceptibility to Death during the 2009 H1N1 Pandemic. [PDF]
Recent outbreaks of H5, H7, and H9 influenza A viruses in humans have served as a vivid reminder of the potentially devastating effects that a novel pandemic could exert on the modern world.

Pathogenesis of swine influenza virus (Thai isolates) in weanling pigs: an experimental trial
Background The objective of this study is to investigate the pathogenesis of swine influenza virus (SIV) subtype H1N1 and H3N2 (Thai isolates) in 22-day-old SPF pigs. Results The study found that all pigs in the infected groups developed typical signs of

Mimicry between proteins of human and avian influenza viruses and host immune system proteins
Viral infection can lead to dangerous and severe manifestations associated with immunosuppression and a cytokine storm. The last is typical for influenza A virus infection of H1N1 subtype, when the level of cytokines in the peripheral blood is ...
