Transcriptome response of murine alveolar epithelial cells to infection by three unrelated respiratory viruses commonly studied in mouse models

ABSTRACT: The severity and outcome of respiratory viral infections is partially determined by the cellular response mounted by infected lung epithelial cells. Disease prevention and treatment is dependent on our understanding of the shared and unique responses elicited by diverse viruses. We used microarray analysis to compare changes in gene expression of murine lung epithelial cells infected by one of three respiratory viruses causing mild (rhinovirus, RV1B), moderate (coronavirus, MHV-1), and severe (influenza A virus, PR8) disease in mice. The viruses prompted changes in host gene expression that differed in magnitude and timing. RV1B infection caused numerous gene expression changes, but the differential effect peaked at 12 hours post-infection. PR8 altered an intermediate number of genes whose expression continued to changes through 24 hours. MHV-1 had comparatively few effects on host gene expression. All three viruses elicited overlapping responses in antiviral defense systems, though MHV-1 induced a lower type I IFN response than the other two viruses. Our comparative approach identified signatures of each virus infection that can be used to discover mechanisms of pathogenesis in the respiratory tract.

Transcriptome response of murine alveolar epithelial cells to infection by three unrelated respiratory viruses commonly studied in mouse models II

Project description:Rhinoviruses (RV) have been shown to inhibit subsequent infection by heterologous respiratory viruses, including influenza viruses and severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2). To better understand the mechanisms whereby RV protects against pulmonary coronavirus infection, we used a native murine virus, mouse hepatitis virus strain 1 (MHV-1), that causes severe disease in the lungs of infected mice. We found that priming of the respiratory tract with RV completely prevented mortality and reduced morbidity of a lethal MHV-1 infection. Replication of MHV-1 was reduced in RV-primed mouse lungs although type I interferon (IFN-b) expression was more robust in mice infected with MHV-1 alone. We further showed that type I IFN signaling was required for survival of mice given a non-lethal dose of MHV-1. RV-primed mice had reduced pulmonary inflammation and hemorrhage and influx of leukocytes, especially neutrophils, in the airways. RV-mediated priming in the respiratory tract protects against a lethal pulmonary coronavirus infection in mice. This model can be used to understand how heterologous viruses impact each other during coinfection of the respiratory tract.

Alarmin S100A8/A9 mediates activation of aberrant neutrophils in the pathogenesis of COVID-19

Project description:To characterize the early immune responses against coronavirus infection, we infected rhesus macaques and hACE2 transgenic mice with SARS-CoV-2 and analyzed the transcriptome of infected and non-infected animals. We infected WT mice with IAV as a normal respiratory virus group. During analysis, we found that S100A8 was dramatically upregulated by SARS-CoV-2 and a mouse coronavirus (mouse hepatitis virus, MHV), but not by other tested viruses. A group of non-canonical neutrophils were also activated during SARS-CoV-2 infection.

microRNA-mediated GALNT3 upregulation facilitates mucin production and viral replication in influenza A virus-infected respiratory epithelial cells

Project description:Viral infections affecting the upper or lower respiratory tract induce mucin production in the epithelial surfaces of the respiratory cells. However, a little is known about how mucins are produced on the surfaces of respiratory epithelial cells and affects viral replication. In the course of the investigation of the cellular responses in the early stage of Influenza A virus (IAV) infection, we found that two miRNAs, miR-221 and miR-17-3p, which target the mRNA of GalNAc transferase 3 (GALNT3), are rapidly down-regulated as early as 1.5 h post-infection. To understand the early host cell responses to the IAV infection, we performed miRNA microarray analysis using a human alveolar adenocarcinoma cell line, A549 cells, infected with influenza A/Puerto Rico/8/34 H1N1 (PR8) virus. We isolated the cellular RNAs at 0.5, 1.5 and 4.5 h post-infection and detected significant changes in the global profile of miRNA expression after infection with IAV. mouse embryonic fibroblasts. Each sample was run in duplicate.

Host responses that correlate with respiratory droplet transmission of swine-origin influenza viruses in ferrets.

Project description:The determinants of influenza transmission remain poorly understood. Swine influenza viruses preferentially attach to receptors found in the upper airways; however, most swine influenza viruses fail to transmit efficiently from swine to humans, and from human-to-human. The pandemic 2009 H1N1 (H1N1pdm) virus was a rare exception of a swine virus that acquired efficient transmissibility from human-to-human, and is reflected in efficient respiratory droplet transmission in ferrets. We hypothesize that virus-induced host responses in the upper airways correlate with airborne transmission in ferrets. To address this question, we used the H1N1pdm virus and swine influenza A/swine/Hong Kong/201/2010 (HK201) virus that has comparable titre in the ferret nasopharynx, but it exhibits differential transmissibility in ferrets via respiratory droplet route. We performed a transcriptomic analysis of tissues from the upper and lower respiratory tract from ferrets infected with either H1N1pdm or HK201 viruses using ferret-specific Agilent oligonucleotide arrays. We found differences in the kinetics of the innate immune response elicited by these two viruses that varied across tissues.

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

Project description: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. Macrophages were infected with low (PR8) and high pathogenic influenza viruses (FPV and H5N1)

Dynamic responses of primary human bronchial epithelial cells to influenza virus, viral RNA and interferon-beta

Project description:We defined the major transcriptional responses in primary human bronchial epithelial cells (HBECs) after either infection with influenza or treatment with relevant ligands. We used four different strategies, each highlighting distinct aspects of the response. (1) cells were infected with the wild-type PR8 influenza virus that can mount a complete replicative cycle. (2) cells were transfected with viral RNA (âvRNAâ) isolated from influenza particles. This does not result in the production of viral proteins or particles and identifies the effect of RNA-sensing pathways (e.g., RIG-I.). (3) Cells were treated with interferon beta (IFNb), to distinguish the portion of the response which is mediated through Type I IFNs. (4) Cells were infected with a PR8 virus lacking the NS1 gene (âDNS1â). The NS1 protein normally inhibits vRNA- or IFNb-induced pathways, and its deletion can reveal an expanded response to infection. HBECs were stimulated with a 15 minute pulse of 1000U/ml IFNÃ (PBL, Piscataway, NJ), 100ng/ml vRNA (purified directly from PR8 virus) with LTX transfection reagent (Invitrogen; Carlsbad, California), wild type H1N1 influenza (A/PR/8/34) or ?NS1 virus (PR8 with a deleted NS1 gene, gift from Dr. Garcia-Sastre). Viruses were used at a multiplicity of infection (moi) of 5. Control samples were incubated with media or LTX under the same conditions. Cells were washed, supplemented with warm media and harvested at 11 timepoints (0, .25, .5, 1, 1.5, 2, 4, 6, 8, 12, and 18 hours post-treatment). HBECs were seeded in 6 well plates at a concentration of 250,000/well 18 hours prior to stimultaion. Cells were stimulated with a 15 minute pulse of IFNb, vRNA, infected with PR8 influenza or NS1 deleted influenza, or mock treated

Determination of MHV RNA poly(A) tail length and 3' end additions upon 17-CL1 cells infection [17-CL1_WT]

Project description:The mouse hepatitis virus (MHV) genomic and sub-genomic RNAs are 3’ polyadenylated. The length of the 3’ poly(A) tail is known to change during infection, but little is known about the molecular mechanisms driving this change. Here, we investigate the presence of terminal uridylation and terminal guanylation on the MHV poly(A) tail during infection. We infected 17-CL1 cells with MHV and isolated RNA at 24- and 48-hour post-infection (hpi). We observed that MHV RNAs poly(A) tails shortened during infection and that short poly(A) tails of about 20 nucleotides are highly uridylated.

A Systems Approach to Understanding Human Rhinovirus and Influenza Virus Infection

Project description:Human rhinovirus and influenza virus infections of the upper airway lead to colds and the flu and can trigger exacerbations of lower airway diseases including asthma and chronic obstructive pulmonary disease. Despite modest advances in the diagnosis and treatment of infections by these viruses, novel diagnostic and therapeutic targets are still needed to differentiate between the cold and the flu, since the clinical course of influenza can be severe while that of rhinovirus is usually more mild. In our investigation of influenza and rhinovirus infection of human respiratory epithelial cells, we used a systems approach to identify the temporally changing patterns of host gene expression from these viruses. After infection of human bronchial epithelial cells (BEAS-2B) with rhinovirus, influenza virus or co-infection with both viruses, we studied the time-course of host gene expression changes over three days. From these data, we constructed a transcriptional regulatory network model that revealed shared and unique host responses to these viral infections such that after a lag of 4-8 hours, most cell host responses were similar for both viruses, while divergent host cell responses appeared after 24-48 hours. The similarities and differences in gene expression after epithelial infection of rhinovirus, influenza virus, or both viruses together revealed qualitative and quantitative differences in innate immune activation and regulation. These differences help explain the generally mild outcome of rhinovirus infections compared to influenza infections which can be much more severe. Human bronchial epithelial cells (BEAS-2B) were infected with rhinovirus, influenza virus or both viruses and RNAs were then profiled at 10 time points (2, 4, 6, 8, 12, 24, 26, 48, 60 and 72hrs)
