Project description:There is a life-long relationship between rhinovirus (RV) infection and the development and clinical manifestations of asthma. In this study we demonstrate that cultured primary bronchial epithelial cells from adults with asthma (n = 9) show different transcriptional and chromatin responses to RV infection compared to those without asthma (n = 9). Both the number and magnitude of transcriptional and chromatin responses to RV were muted in cells from asthma cases compared to controls. Pathway analysis of the transcriptionally responsive genes revealed enrichments of apoptotic pathways in controls but inflammatory pathways in asthma cases. Using promoter capture Hi-C we tethered regions of RV-responsive chromatin to RV-responsive genes and showed enrichment of these regions and genes at asthma GWAS loci. Taken together, our studies indicate a delayed or prolonged inflammatory state in cells from asthma cases and highlight genes that may contribute to genetic risk for asthma.

Project description:Rhinovirus (RV) infection has been shown to exacerbate asthma. Understanding of the underlying mechanisms by which RV infections provoke airway inflammation and remodeling in asthma may offer significant insight into asthma pathogenesis and exacerbations as well as offer opportunities for improved disease management. Expression analysis of RV A16-treated primary peripheral blood monocytes from human donors was performed to determine what pattern of gene expression is associated with RV infection of monocytes in vitro.

Project description:Rhinovirus infections exacerbate chronic respiratory inflammatory diseases such as asthma and chronic obstructive pulmonary disease (COPD). Airway epithelial cells are the primary site of rhinovirus replication and responsible for initiating the host immune response to infection. Numerous studies have reported that the anti-viral innate immune response in asthma is deficient leading to the conclusion that epithelial innate immunity is a key determinant of disease severity during a rhinovirus induced exacerbation. However, deficient rhinovirus-induced epithelial interferon production in asthma has not always been observed. We hypothesised that disparate in vitro airway epithelial infection models lacking genome-wide, time-course analyses have obscured the role of epithelial innate anti-viral immunity in asthma and COPD. To address this, we developed a low multiplicity of infection (MOI) rhinovirus model of differentiated primary epithelial cells obtained from healthy, asthma and COPD donors. Using genome-wide gene expression following infection, we demonstrated that gene expression patterns are similar across patient groups, but that the kinetics of induction are delayed in cells obtained from asthma and COPD donors. Rhinovirus-induced innate immune responses were defined by interferons (type-I, II and III), interferon response factors (IRF1, IRF3 and IRF7), TLR signalling and NF‐kB and STAT1 activation. Induced gene expression was evident at 24 hours and peaked at 48 hours post‐infection in cells from healthy subjects. In contrast, in cells from donors with asthma or COPD induction was maximal at or beyond 72-96 hours post infection. Thus, we propose that propensity for viral exacerbations of asthma and COPD relate to delayed (rather than deficient) expression of epithelial cell innate anti-viral immune genes which in turns leads to a delayed and ultimately more inflammatory host immune response.

Project description:Rhinovirus (RV) infection has been shown to exacerbate asthma. Understanding of the underlying mechanisms by which RV infections provoke airway inflammation and remodeling in asthma may offer significant insight into asthma pathogenesis and exacerbations as well as offer opportunities for improved disease management. Expression analysis of RV A16-treated primary peripheral blood monocytes from human donors was performed to determine what pattern of gene expression is associated with RV infection of monocytes in vitro. Peripheral blood monocytes were isolated from 5 adults. Following overnight incubation in RPMI supplemented with 10% FBS, the monocytes were stimulated with purified major group RV A16 at multiplicity of infection of 10 plaque forming units (pfu) per cell or with growth media alone (mock). Cells were lysed 4 hours after treatment and isolated total RNAs were pooled per treatment and analyzed using the Affymetrix GeneChip HuGeneFL Array (Hu6800, Affymetrix, Santa Clara, CA).

Project description:Rhinoviruses (RVs) are major instigators of acute exacerbations of asthma, COPD and other respiratory diseases. RVs are categorized into three species (RV-A, RV-B, and RV-C), which comprise more than 160 serotypes, making it difficult to develop an effective vaccine. Currently no effective treatment for RV infection is available. Pulmonary surfactant is an extracellular complex of lipids and proteins that plays a central role in regulating innate immunity in the lung. The minor pulmonary surfactant lipids, palmitoyl-oleoyl-phosphatidylglycerol (POPG) and phosphatidylinositol (PI), are potent regulators of inflammatory processes, and exert antiviral activity against respiratory syncytial virus (RSV) and influenza A viruses (IAV). In the current study, we examined the potencies of POPG and PI against rhinovirus A16 (RV-A16) in primary human airway epithelial cells (AECs) differentiated at an air-liquid interface (ALI). After AECs were infected with RV-A16, PI reduced viral RNA copy number by 80% and downregulated (55-65%) expression of antiviral genes (MDA5, IRF7 and IFN-lambda). In contrast, POPG only slightly decreased MDA5 (24%) and IRF7 (11%) gene expression but did not inhibit IFN-lambda gene expression or RV-A16 replication in AECs. However, both POPG and PI inhibited (50-80%) IL6 and CXCL11 gene expression and protein secretion. PI treatment dramatically attenuated global gene expression changes induced by RV-A16 infection in AECs. Cell type enrichment analysis of viral regulated genes opposed by PI treatment revealed that PI inhibited viral induction of goblet cell metaplasia and virus-induced downregulation of ciliated, club, and ionocyte cell types. Notably, PI treament altered the ability of RV-A16 to regulate expression of some phosphatidylinositol 4-kinase (PI4K), acyl-CoA binding domain containing (ACBD) and low density lipoprotein receptor (LDLR) genes that play critical roles in the formation and functioning of replication organelles (ROs) required for RV replication in host cells. These data suggest PI can be used as a potent, non-toxic antiviral agent for RV infection prophylaxis and treatment.

Project description:Background: Evidence suggests that immune responses to rhinovirus A and C are altered in asthmatic children and rhinovirus species induce different types of antibody responses. Objective: To ascertain and compare the T-cell memory response induced by RV-A and RV-C in asthmatic and non-asthmatic children. Methods: Peripheral blood mononuclear cells from children who previously suffered asthma exacerbation (asthmatics) and non-asthmatic controls were stimulated in vitro with peptide formulations to induce representative species-specific responses to RV-A and RV-C. Expression of genes was measured by RNA-seq and differentially expressed genes were further analysed to identify enriched pathways and upstream regulators. Results: Responses to RV-A showed markedly higher upregulation of IFNG and the IFNG responsive genes CXCL9, 10 and 11 and STAT1 compared to RV-C. There was no reciprocal upregulation of Th2 cytokine genes or the Th2 chemokine genes CCL11, CCL17 and CCL22. RV-C but not RV-A induced high upregulation of CCL24 (eotaxin-2) in both non-asthmatic and asthmatic responses. Upstream regulator analysis showed both RV-A and, although to a diminished extent, RV-C induced predominant Th1 and inflammatory cytokine expression. The responses of asthmatics compared to non-asthmatics was diminished to both RV-A and RV-C while retaining the pattern for gene expression and upstream regulators characteristic of each species and there was no upregulation of Th2-type responses. All groups showed activation of the IL-17A pathway. Conclusions: RV-C induced memory cells with a lower IFNG type response than RV-A without Th2 upregulation. Asthmatics had lower recall responses than non-asthmatics while largely retaining the same gene activation profile for each species.

Project description:Rhinovirus (RV) is the most prevalent human respiratory virus. Each year, RV infects billions of people and is responsible for at least half of all common colds, the most common illness of humans. RV infection also affects the morbidity of a range of respiratory illnesses, such as bronchiolitis, pneumonia, asthma, chronic obstructive pulmonary disease, and cystic fibrosis. Despite its biological importance and public health significance, little is known about the genetic architecture of response to RV. To address this, we obtained genome-wide genotype and gene expression data in uninfected and RV-infected peripheral blood mononuclear cells (PBMCs) from 98 individuals. We characterized gene expression differences in response to RV infection and mapped expression quantitative trait loci (eQTLs) in both uninfected and RV-infected PBMCs. The study includes data from uninfected and rhinovirus-infected peripheral blood mononuclear cells (PBMCs) from 98 individuals. Twenty ml of blood was drawn from each participant. PBMCs were isolated from whole blood samples by Ficoll-Paque separation. From each subject, 4 million PBMCs were treated with media alone for 24 hours and 4 million PBMCs were treated with media containing RV16 for 24 hours. The multiplicity of infection was 10 plaque-forming units per cell. Total RNA was extracted after 24-hour incubation, using the RNeasy Plus Mini Kit; concentrations were measured on a Nanodrop ND-100 Spectrophotometer and quality was assessed using an Agilent 2100 Bioanalyzer. Genome wide gene expression profiling of uninfected and rhinovirus-infected PBMCs was obtained using Illumina HumanHT-12 v4 Expression BeadChip arrays at the University of Chicago Functional Genomics Core.
