ATAC-seq studies of Rhinovirus Response in asthma cases and non-asthma controls

ABSTRACT: 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.

Lipopolysaccharide modulates rhinovirus-induced chemokine secretion in monocytes and macrophages.

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).

Rhinovirus-induced human lung tissue responses mimic respiratory disease signatures allowing evaluation of therapeutics

Project description:Human rhinovirus (RV) is a major risk factor for COPD and asthma exacerbations, but exploration of RV pathogenesis has been hampered by a lack of disease relevant model systems. We performed a detailed characterization of host mRNA responses to RV infection in human precision cut lung tissue ex vivo (comparing to previously published asthma and COPD studies) and explored the impact of antiviral treatment. Genomic analyses revealed that RV not only induced anti-viral immune responses but also triggered changes in epithelial cell-associated pathways. Strikingly, the RV response in PCLS was reflective of gene expression changes described previously in COPD and asthma patients. While RV-induced host immune responses were abrogated by rupintrivir, RV-triggered epithelial processes were largely refractory to antiviral treatment.

Differential gene expression of lymphocytes stimulated with rhinovirus species A and C in asthmatic and non-asthmatic children

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.

Rhinovirus-induced modulation of gene expression in bronchial epithelial cells from subjects with asthma

Project description:Human Rhinovirus (HRV) infection can trigger exacerbations of asthma. Understanding of the mechanisms provoking airway inflammation and remodeling in asthma, as well as the pathogenic mechanisms of HRV infection and its association with asthma exacerbations, may offer significant opportunities for improved disease management. Genome-wide expression analysis of HRV type 1A-infected primary bronchial epithelial (PBE) cells from normal and asthmatic donors was performed to determine whether asthma is associated with a unique pattern of gene expression after HRV infection in vitro. Keywords: response to rhinovirus infection

Gene expression data from uninfected and rhinovirus-infected peripheral blood mononuclear cells from 98 individuals

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.
