The pathogenesis of Influenza A (H1N1) has attracted focused attention internationally. It has been known that Influenza A (H1N1) virus inducing host cells apoptosis is one of the most important mechanisms in its pathogenesis. Many studies have demonstrated that it is Caspases that mediates the process of Influenza A (H1N1) virus induced host cells apoptosis, which can be regulated via multiple ways, factors and genes. It has been proved that Influenza A (H1N1) virus induced host cells apoptosis is a complex process [1].
