Comparative Analysis of Genes Induced by Respiratory Syncytial Virus and DsRNA in Human Epithelial Cells

ABSTRACT: Epithelial cells are the primary target of respiratory viral infections and play a pivotal role in virus-induced lung inflammation and in anti viral immune response. A common signal for the presence of viral infections and induction of inflammation is recognition of double stranded RNA (dsRNA). Thus far, there has not been a high-throughput transcrptome analysis of RSV- or dsRNA-induced genes in primary human bronchial epithelial cells (PHBE), nor there has been a comparison between dsRNA- and RSV-induced genes. To establish the transcriptome profiles and to determine the contribution of dsRNA in the induction of inflammation during respiratory virus infection, we compared the gene expression profiles of PHBE cells that were infected with RSV or were treated with dsRNA. Our transcriptome analysis showed that RSV infection and and dsRNA treatment induced up-regulation of 2024 and 159 genes in PHBE respectively. Comparison of genes revealed that RSV and dsRNA commonly induced 80 genes in PHBE cells. The common up-regulated genes were functionally grouped in multiple response pathways involved in inflammation and immune responses. Interestingly, there were several previously unreported genes that were up-regulated in primary human epithelial cells that are relevant to a TH2 allergic phenotype. This comparison of a high-throughput gene expression study offers a comprehensive view of transcriptional changes induced by dsRNA and RSV, and importantly compares dsRNA-induced genes with RSV-induced genes in PHBE cells.

RSV-induced Cytoskeletal Inflammation

Project description:We studied RSV infection in an appropriate in vitro model of respiratory epithelium, a pseudostratified and fully differentiated mucociliary epithelium of normal human bronchial epithelial (NHBE) cells. RSV infection increased actin cytoskeleton without compromising adherent-, tight-, and tricellular-junctions as well as ciliary functions and epithelial tissue barrier integrity. This increased cytoskeleton depends on actin polymerization and the induction of proinflammatory cytokines and chemokines. Thus, we observed a novel signature “increased cytoskeleton” termed “cytoskeletal inflammation” in RSV-infected respiratory epithelium that presumably lacks classical antigen presenting cells, such as resident dendritic cells and macrophages. Our results suggest that RSV-induced cytoskeletal inflammation is a noncanonical earliest host response to the pathogen and contributes to airway inflammation.

RSV vs BSA

Project description:Rationale: Respiratory syncytial virus (RSV) and Streptococcus pneumoniae are major respiratory pathogens. Co-infection with RSV and S. pneumoniae is associated with severe and often fatal pneumonia but the molecular basis for this remains unclear. Objectives: To determine if interaction between RSV and pneumococci enhances pneumococcal virulence. Methods: We used confocal microscopy and western blot to identify the receptors involved in direct binding of RSV and pneumococci, the effects of which were studied in both in vivo and in vitro models of infection. Human ciliated respiratory epithelial cell cultures were infected with RSV for 72h and then challenged with pneumococci. Pneumococci were collected after 2h exposure and changes in gene expression determined using qRT-PCR. Results: Following incubation with RSV or purified G protein, pneumococci demonstrated a significant increase in the inflammatory response and bacterial adherence to human ciliated epithelial cultures and markedly increased virulence in a pneumonia model in mice. This was associated with extensive changes in the pneumococcal transcriptome and significant upregulation in the expression of key pneumococcal virulence genes, including the gene for the pneumococcal toxin, pneumolysin. We show that mechanistically this is due to RSV G glycoprotein binding penicillin binding protein 1a. Conclusion: The direct interaction between a respiratory virus protein and the pneumococcus resulting in increased bacterial virulence and worsening disease outcome is a new paradigm in respiratory infection.

TGF-beta treated airway epithelium

Project description:Despite being exposed to respiratory syncytial virus (RSV) infection multiple times in our lives, infants, older-adults, and immunocompromised patients are vulnerable to RSV-associated severe diseases, such as bronchiolitis and pneumonia. Respiratory viral infections are known to promote pulmonary fibrosis formation, which are often associated with a cellular remodeling process epithelial-mesenchymal transition (EMT). However, there is no information on whether RSV causes EMT in bronchial epithelial cells. Our results suggest that RSV-infection does not induce EMT in three different in vitro lung models: epithelial A549 cell line, primary normal human bronchial epithelial cells, and pseudostratified airway epithelium. Interestingly, RSV infection increased cell surface area and perimeter in the infected airway epithelium, which is distinct from the TGF-β1 driven cell elongation. Genome-wide transcriptome analysis also revealed that RSV infection is not involved in cell motility and locomotion. Thus, our results suggest that RSV infection does not induce EMT in the airway epithelium

Double-Stranded RNA-Activated Protein Kinase Regulates early innate immune responses during RSV Infection

Project description:Respiratory Syncytial virus (RSV) is the most common cause of childhood viral bronchiolitis and lung injury. Inflammatory responses significantly contribute to lung pathologies during RSV infections and bronchiolitis but the exact mechanisms have not been completely defined. The double-stranded RNA-activated protein kinase (PKR) functions to inhibit viral replication and participates in several signaling pathways associated with innate inflammatory immune responses. Using a functionally defective PKR (PKR-/-) mouse model, we investigated the role of this kinase in early events of RSV-induced inflammation. Our data showed that bronchoalveolar lavage (BAL) fluid of infected PKR-/- mice had significantly lower levels of several innate inflammatory cytokines and chemokines. Histological examinations revealed that there was less lung injury in infected PKR-/- mice as compared to the wild type. A genome-wide analysis showed that several early anti viral and immune regulatory genes were affected by PKR activation. These data suggest that PKR is a signaling molecule for immune responses during RSV infections.

Xuanfei Formula Attenuates RSV Infection

Project description:RSV, a leading cause of severe respiratory illnesses in vulnerable populations, lacks effective, affordable treatments for pediatric use. The potential of traditional Chinese medicine for relieving viral symptoms prompted this investigation into Xuanfei Formula (XFF) as an anti-RSV agent. This study employed H&E staining, cytokine profiling, and RSV titer quantification in BALB/c mice to evaluate the impact of XFF on RSV infection. Strikingly, immediate post-treatment observation showed a precipitous drop in both serum pro-inflammatory cytokine levels and pulmonary RSV-N gene copies in comparison to infected controls, suggesting XFF’s direct anti-RSV action. Transcriptome analyses were used to pinpointed the underlying mechanism behind formula’s immune-independent anti-RSV, a leading cause of severe respiratory illnesses in vulnerable populations, lacks effective, affordable treatments for pediatric use.

Dexamethasone inhibits respiratory syncytial virus-driven mucus production while increasing viral replication without altering antiviral interferon signaling

Project description:Purpose: To understand how dexamethasone has beneficial effects on reducing mucus production but inhibits viral defense mechanisms Methods: RSV-infected mouse lungs and various cell lines, plus and minus dexamethason, were examined by RNAseq, and pathway analysis of differentially-expressed genes were compared Results: Using RNA-seq we identified a subset of cytokines that were induced by RSV and repressed by dexamethasone. Interestingly, while RSV induced interferons (IFNs) and IFN stimulated genes (ISGs), dexamethasone treatment did not affect the expression of these genes or antiviral IFN signaling pathways as has been observed with glucocorticoid treatment of other respiratory viruses [13]. Using an unbiased approach, we found that certain RSV-driven gene expression networks and genes were specifically modulated by dexamethasone treatment. Importantly, dexamethasone also reduced RSV clearance in vivo, which correlated with a reduction in specific immune response markers. Conclusion: Our results support the possibility that the beneficial anti-inflammatory effects of dexamethasone treatment are counterbalanced by the increased viral load in patients, accounting for the lack of clinical benefit derived from treatment during RSV infection.

8-Oxoguanine DNA glycosylase 1 hijacked by nucleoprotein conceals guanine oxidation in respiratory syncytial virus RNA

Project description:Respiratory Syncytial Virus (RSV), alongside other prominent respiratory RNA viruses such as influenza and SARS-CoV-2, significantly contributes to the global incidence of respiratory tract infections. These pathogens prompt the production of reactive oxygen species (ROS), which play a crucial role in the onset and progression of respiratory diseases. However, the strategies by which viral RNA manages ROS-induced base oxidation are not well understood. Here we uncover that 8-oxo-7,8-dihydroguanine (8-oxoGua) is not merely an incidental byproduct of ROS activity but serves as a strategic adaptation of RSV RNA during replication within host cells. Through RNA immunoprecipitation and next-generation sequencing, we discovered that 8-oxoguanine DNA glycosylase 1 (OGG1) binding sites are predominantly found in the RSV antigenome, especially within guanine-rich areas. Further investigation revealed that viral ribonucleoprotein complexes specifically hijack OGG1. Crucially, our findings show that inhibiting OGG1's ability to recognize 8-oxoGua leads to a substantial reduction in RSV progeny production. Our results underscore the viral replication machinery's adaptation to oxidative challenges, pointing to the inhibition of OGG1's reading function as a potential novel strategy for antiviral intervention.

Viral N6-methyladenosine upregulates replication and pathogenesis of human respiratory syncytial virus

Project description:N6-methyladenosine (m6A) is the most prevalent internal modification of mRNAs in most eukaryotes. Likewise, viral RNAs may acquire m6A methylation during replication within these cells. Here we show that RNAs of human respiratory syncytial virus (RSV), a medically important non-segmented negative-sense (NNS) RNA virus, are modified by m6A within discreet regions and that these modifications enhance viral replication and pathogenesis. Overexpression of m6A binding proteins significantly enhanced RSV replication and gene expression. Knockdown of m6A methyltransferases decreased viral replication and gene expression whereas knockdown of m6A demethylases had the opposite effect. The G gene contained the most abundant m6A modifications. Recombinant RSV expressing a G gene lacking different m6A sites, resulted in RSVs with various degrees of defects in replication in A549 cells, primary well differentiated human airway epithelial (HAE) cultures, upper and lower respiratory tract of cotton rats, and were also less pathogenic to the lungs of cotton rats. One of the m6A-deficient rgRSVs, rgRSV-G12, was completely attenuated yet retained high immunogenicity in cotton rats. Moreover, a small molecule that inhibits S-adenosyl-L-homocysteine (SAH) hydrolase, thereby reducing the cellular SAH pool and viral RNA m6A, also inhibited RSV replication in HAE cells. Collectively, our results demonstrate viral m6A methylation upregulates RSV replication and pathogenesis and identify viral m6A methylation as a target for rational design of live attenuated vaccine candidates and for novel antiviral therapeutic agents for RSV.
