A quantitative proteomic analysis of lung epithelial (A549) cells infected with 2009 pandemic influenza A virus using stable isotope labelling with amino acids in cell culture.

Influenza A virus is one of the world's major uncontrolled pathogens, causing seasonal epidemics as well as global pandemics. This was evidenced by the recent emergence and now prevalence of the 2009 swine origin pandemic H1N1 influenza A virus. In this study, quantitative proteomics using stable isotope labelling with amino acids in cell culture was used to investigate the changes in the host cell proteome in cells infected with pandemic H1N1 influenza A virus.
