Influenza virus infected HUVEC. Homo sapiens

To delineate specific patterns of signaling networks activated by H5N1 we used a comparative systems biology approach analyzing gene expression in endothelial cells infected with three different human and avian influenza strains of high and low pathogenicity. Overall design: HUVECs were infected with either PR8, FPV or H5N1 virus. We used wildtype HUVEC or HUVEC transfected with a dominant negative mutant of IKK2 (block of the NF-kB signaling pathway). In case of FPV infections we also blocked p38 MAP kinase with an SB-inhibitor.
