Host gene expression profiling in influenza A virus-infected lung epithelial (A549) cells: a comparative analysis between highly pathogenic and modified H5N1 viruses

Abstract
To understand the molecular mechanism of host responses to highly pathogenic avian influenza virus infection and to get an insight into the means through which virus overcomes host defense mechanism, we studied global gene expression response of human lung carcinoma cells (A549) at early and late stages of infection with highly pathogenic avian Influenza A (H5N1) virus and compared it with a reverse genetics modified recombinant A (H5N1) vaccine virus using microarray platform.
