(Submitter supplied) Virus and host factors contribute to cell-to-cell variation in viral infection and determine the outcome of the overall infection. However, the extent of the variability at the single cell level and how it impacts virus-host interactions at a systems level are not well understood. To characterize the dynamics of viral transcription and host responses, we used single-cell RNA sequencing to quantify at multiple time points the host and viral transcriptomes of human A549 cells and primary bronchial epithelial cells infected with influenza A virus. more...

(Submitter supplied) Host-influenza virus interplay at the transcript level has been extensively characterized in epithelial cells. Yet, there are no studies that simultaneously characterize human host and influenza A virus (IAV) genomes. We infected human bronchial epithelial BEAS-2B cells with two seasonal IAV/H3N2 strains, Brisbane/10/07 and Perth/16/09 (reference strains for past vaccine seasons) and the well-characterized laboratory strain Udorn/307/72. more...

(Submitter supplied) Replication defective viral genomes (DVGs) generated during virus replication are the primary triggers of antiviral immunity in many infections. However, DVGs also provide viruses with an evolutionary advantage by facilitating virus persistence. Why and how DVGs and the host interact to achieve these two divergent functions remains unknown. We report that DVGs engage a MAVS-mediated antiviral response that promotes apoptosis on highly infected cells while protecting cells dominated by DVGs from death. more...

(Submitter supplied) We developed VODKA (Viral Opensource DVG Key Algorithm) to identify cbDVGs from RNA-Seq data from infected samples and used these DVG sequences to identify signals that regulate cbDVG generation. We applied VODKA to datasets from RSV-positive patients. VODKA identified common cbDVGs across multiple samples in both patients, and predicted specific genomic loci that mediate cbDVG formation.

(Submitter supplied) The outcome of viral infection is extremely heterogeneous at the cellular level, and infected cells only sometimes activate innate immunity. Here we assess how the genetic variation inherent in viral populations contributes to this heterogeneity. We do this by developing a new approach to determine both the cellular transcriptome and full-length sequences of all viral genes in single influenza-infected cells. more...

(Submitter supplied) Parasitic elements of the viral population which are unable to replicate on their own yet rise to high frequencies, defective interfering particles are found in a variety of different viruses. Their presence is associated with a loss of population fitness, both through the depletion of key cellular resources and the stimulation of innate immunity. For influenza A virus, these particles contain large internal deletions in the genomic segments which encode components of the heterotrimeric polymerase. more...

(Submitter supplied) The host response to influenza A infections is strongly influenced by host genetic factors. Animal models of genetically diverse mouse strains are well suitable to identify host genes involved in severe pathology, viral replication and immune responses. Here, we have utilizing a dual RNAseq approach that allowed us to investigate both viral and host gene expression in the same individual from a single expression assay after H1N1 infection. more...

(Submitter supplied) Influenza A virus has a broad cellular tropism in the respiratory tract. Infected epithelial cells sense the infection and initiate an antiviral response. To define the antiviral response at the earliest stages of infection we used two different single cycle replication reporter viruses. These tools demonstrated heterogeneity in virus replication levels in vivo. Transcriptional profiling demonstrated tiers of interferon stimulated gene responses that were dependent on the magnitude of virus replication. more...

(Submitter supplied) The purpose of this experiment was to understand the pathogenic role of individual 1918 genes on the host response to the 1918 pandemic influenza virus. We examined reassortant avian viruses nearly identical to the pandemic 1918 virus (1918-like avian virus) carrying either the 1918 HA or PB2 gene. Both genes enhanced 1918-like avian virus replication, but only the mammalian host adaptation of the 1918-like avian virus through reassortment of the 1918 PB2 led to increased lethality in mice. more...

(Submitter supplied) Viral infection can dramatically alter a cell's transcriptome. However, these changes have mostly been studied by bulk measurements on many cells. Here we use single-cell mRNA sequencing to examine the transcriptional consequences of influenza virus infection. We find extremely wide cell-to-cell variation in production of viral gene transcripts -- viral transcripts compose less than a percent of total mRNA in many infected cells, but a few cells derive over half their mRNA from virus. more...

(Submitter supplied) Human Bocavirus 1(HBoV1), which belongs to the genus Bocaparvovirus of the family Parvoviridae, infects well differentiated human airway epithelium which is at mitotically quiescent state. To systematicaly investigate the host and viral small RNA expression after HBoV1 infection of primary human airway epithelium cultured at an air-liquid interface (HAE-ALI), small RNA-seq was applied to study the small RNA transcriptome profile of HAE-ALI infected by HBoV1.

(Submitter supplied) Transcriptome analysis of mock or H1N1 IAV PR8 infected p53WT A549 and p53null A549-KO3 cells by Affymetrix GeneChip Human Transcriptome 2.0 Arrays to achieve a set of genes those are regulated by p53 and responsive to IAV infection. Influenza A virus infection activates cellular p53, however it has not been clear whether this process has pro- or anti- viral effects. In this study, using human isogenic p53 wildtype A549 cells and p53null A549-KO3 cells generated from the CRISPR/Cas9 technology, we report that p53null cells exhibit significantly reduced viral propagation property when infected with influenza A virus (H1N1/A/Puerto Rico/8/34). more...

(Submitter supplied) The influenza virus is a major cause of morbidity and mortality worldwide, yet, the impact of intracellular viral invasion and the cellular response diversity remain uncharacterized. By massively parallel single-cell RNA-seq we comprehensively mapped the host lung response to in-vivo influenza infection in wild-type and Irf7-knockout mice across nine immune and non-immune cell types. We found an unexpected high prevalence of infected cells in all cell types, showed that infection is a characteristic property of cell types that is independent of type-I interferon activity, and demonstrated that all cell types responded primarily with a robust generic transcriptional response. more...

(Submitter supplied) We aimed at systematically inferring the regulatory functions of host lncRNAs in response to influenza A virus (IAV) and severe acute respiratory syndrome coronavirus (SARS-CoV) in the mouse model, using a ‘guilt-by-association’ approach which relies on finding which lncRNAs have similar expression profiles to protein-coding genes of known function. To build a large panel of diverse host responses to viral infection, we took advantage of the genetic diversity present in the 8 founder strains of the Collaborative Cross (CC) mouse resource. more...

(Submitter supplied) Classical antiviral therapy inhibit viral proteins and are subject to resistance. To counteract this emergence, alternative strategy has been developed that target cellular factors. We hypothesized that such approach could also be useful to identify broad antivirals.
