Proteomic and bioinformatic characterization of extracellular vesicles released from human primary macrophages upon influenza A infection

ABSTRACT: We have previously shown that IAV infection of human monocyte-derived macrophages causes major alterations to subcellular protein trafficking inside the cell and triggers robust protein secretion (Lietzén et al, 2011). Here, we have used high-throughput proteomics to identify proteins secreted in extracellular vesicles (EVs) during influenza A virus infection of human macrophages.

Influenza A viruses (IAVs) are aggressive pathogens that cause acute respiratory diseases and annual epidemics in humans. Host defense against IAV infection is initiated by macrophages, which are the principal effector cells of the innate immune system. We have previously shown that IAV infection of human macrophages is associated with robust secretion of proteins via conventional and unconventional protein release pathways. Here we have characterized unconventional, extracellular vesicle (EV)-m ...[more]

Transcriptomics of isolated alveolar macrophages from WT and CD47 deficient mice upon influenza A virus infection

Project description:CD47 is an ubiquitously expressed surface molecule that has a significant impact on immune responses. However, its role for antiviral immunity is not fully understood. We can show that CD47 has an inhibitory role in influenza virus defense, since CD47-deficient mice (CD47-/-) display an increased viral clearance during influenza virus infection. This effect is strongly associated with alveolar macrophages, yet the underlying mechanisms are unclear. Thus, to assess the precise impact of CD47 on antiviral action of alveolar macrophages, transcriptional analysis of ex vivo isolated alveolar macrophages from CD47-/- and WT mice were performed isolated 3dpi. Surprisingly, instead of classical antiviral mediators, an increased expression of both hemoglobin α and hemoglobin β was found in CD47 deficient compared to WT alveolar macrophages upon influenza A virus infection. Importantly, antiviral activity of hemoglobin was already shown for other viruses and thus, CD47 might limit influenza virus defense via the regulation of hemoglobin, which could act as a modulator of the antiviral immune response during the infection.

Expression data of influenza A infected human macrophages

Project description:Human disease caused by highly pathogenic avian influenza (HPAI) H5N1 can lead to a rapidly progressive viral pneumonia leading to acute respiratory distress syndrome. There is increasing evidence suggests a role for virus-induced cytokine dysregulation in contributing to the pathogenesis of human H5N1 disease. The key target cells for the virus in the lung are the alveolar epithelium and alveolar macrophages, and previous data has shown that compared to seasonal human influenza viruses, equivalent infecting doses of H5N1 viruses markedly up-regulate pro-inflammatory cytokines in both primary cell types in vitro. The dysregulation of H5N1-induced host responses is therefore important for understanding the viral pathogenesis. We used microarrays to analyze and compare the gene expression profiles in primary human macrophages after influenza A virus infection. Peripheral-blood leucocytes were separated from buffy coats of three healthy blood donors and cells were differentiated for 14 days before use. Differentiated macrophages were infected with H1N1 and H5N1 at a multiplicity of infection (MOI) of two. Total RNA was extracted from cells after 1, 3, and 6h post-infection, and gene expression profiling was performed using an Affymetrix Human Gene 1.0 ST microarray platform.

RNA-seq of mouse alveolar macrophages from control and Influenza A virus infected animals

Project description:Based on the observations that influenza infection led to behavioral changes in alveolar macrophages (AMs), we performed an RNAseq experiment to delineate global gene expression changes that occurred in the AM population after influenza infection versus a control (non-infected) population.

Effect of influenza infection on genome structure in human primary cells [Hi-C]

Project description:Hi-C was used to profile changes in the genome structure of human primary cells at multiple time points in response to infection with active and UV-inactivated H5N1 influenza virus. Human tracheobronchial epithelial cells (HTBE) and monocyte-derived macrophages (MDM) were used. 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.

Genome-wide analysis of gene expression in human macrophages in response to infection with recombinant A/WSN/33 influenza A viruses expressing wild type NS1 protein or its mutant R38A, K41A. [macrophages]

Project description:Analysis of gene expression in human macrophages infected with influenza A viruses expressing wild type NS1 protein or its mutant R38A, K41A. The hypothesis tested was that R38 and K41 residues within viral NS1 protein are essential fro transctiptional control of cellluar gene expression. Cells were infected with influenza A/WSN/33 viruses expressing wild type NS1 protein (WT), its R38A, K41A mutant (RK/AA) or non-infected (Mock) Total RNA isolated from macrophages after 10 hours of infection with wild type or mutant influenza A virus (multiplicity of infection = 1)
