The PB1-F2 protein of Influenza A virus: increasing pathogenicity by disrupting alveolar macrophages

With the prospect of another pandemic Influenza fresh in our consciousness, the pathogenic nature of the Influenza A virus and its ability to induce high rates of mortality are ever more pertinent. Recently a novel protein encoded by an alternate reading frame in the PB1 Gene segment of Influenza A virus has been discovered and in turn shown to enhance viral virulence in a mouse model [1]. This protein has been shown to specifically target and destroy alveolar macrophages [2]. This review suggests that this protein, present in all previous pandemic strains, may reappear as a virulence factor in a subsequent pandemic strain. This PB1-F2 protein will enhance the mortality rate of the virus by increasing the likelihood of a secondary bacterial infection, which is the primary cause of death to a patient infected with Influenza A.
