Highly Pathogenic Avian Influenza Viruses Avoid Effective Inflammatory Response of Human Macrophages

ABSTRACT: Macrophages were infected with low (PR8) and high pathogenic influenza viruses (FPV and H5N1). To our surprise a genome-wide comparative systems biology approach revealed that in contrast PR8 infections with HPAIV H5N1 and FPV result in a reduced immune response of human macrophages contradicting a primary role of this cell type for the cytokine storm. Our data point to a viral strategy of HPAIV to bypass a major amplifier of the initial local inflammatory response thereby hampering antiviral effector mechanisms and facilitating virus spreading and systemic disease.

Transcription profiling of HUVEC infected with Influenza virus

Project description: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. 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).

An H5N1 virus-encoded atypical microRNA is a major contributor to cytokine storm and mortality

Project description:An H5N1 virus-encoded microRNA directly targets mammalian poly(rC) binding protein 2 and is a major contributor to H5N1-associated ‘cytokine storm’ and mortality.

MiRNA profiling in lung epithelial cells during infection with influenza A virus of H5N1 strain

Project description:This study aims at elucidating how H5N1 influenza infection perturbs the host's miRNA regulatory pathways that may lead to adverse pathological events, such as cytokine storm, using the miRNA microarray approach. The cell line - NCI-H292, was infected with various preparations of H5N1 influenza viruses was analysed for miRNA expression profiles subsequently. The miRNA expression profiles were measured at 3, 6, 18, and 24 hours post infection, respectively.

Differences in cytokine production in human macrophages and in virulence in mice are attributable to the PA protein of H5N1 influenza viruses

Project description:Background. The pathogenesis of influenza A virus subtype H5N1 (hearafter, "H5N1") infection in humans is not completely understood, although hypercytokinemia is thought to play a role. We previously reported that most H5N1 viruses induce high cytokine responses in human macrophages, whereas some H5N1 viruses induce only a low level of cytokine production similar to that induced by seasonal viruses. Methods. To identify the viral molecular determinants for cytokine induction of H5N1 viruses in human macrophages, we generated a series of reassortant viruses between the high cytokine inducer A/Vietnam/UT3028II/03 clone 2 (VN3028IIcl2) and the low inducer A/Indonesia/UT3006/05 (IDN3006), and evaluated cytokine expression in human macrophages. Results. Viruses possessing the acidic polymerase (PA) gene of VN3028IIcl2 exhibited high levels of hypercytokinemia-related cytokine expression in human macrophages, compared with IDN3006, but showed no substantial differences in viral growth in these cells. Further, the PA gene of VN3028IIcl2 conferred enhanced virulence in mice. Conclusions. These results demonstrate that the PA gene of VN3028IIcl2 affects cytokine production in human macrophages and virulence in mice. These findings provide new insights into the cytokine-mediated pathogenesis of H5N1 infection in humans.

Human monocyte-derived macrophage (MDM) cell transcriptome response to infection with H1N1, H3N2, and H5N1 influenza virus.

Project description:Human monocyte-derived macrophages (MDM) serve as a model for resident alveolar macrophages (AM) in the human respiratory tract. mRNA-Seq analysis was used to profile the cellular transcriptome of MDM cells at multiple time points in response to infection with influenza A/California/04/09 (H1N1), A/Wyoming/03/03 (H3N2), and A/Vietnam/1203/04 (H5N1) HALo virus. The Influenza A/Vietnam/1203/04 (H5N1) HALo mutant virus is an attenuated H5N1 virus generated from wild-type Influenza A/Vietnam/1203/04 (H5N1) virus as described in Steel, J., et al. J Virol. 2009 Feb; 83(4):1742-53.
