Project description:Global patterns of gene expression was profiled in nasal lavage samples obtained from asthmatic children during an acute Picornavirus-induced exacerbation and 7-14 days later. Gene coexpression network analysis and prior knowledge was employed to reconstruct the wiring diagram of the underlying gene networks. The study design consisted of paired samples obtained during the acute exacerbation and 7-14 days later from 16 asthmatic children.

Project description:Asthma is a very frequent airway disease that affects 6 to 20% of the population. Severe asthma, represents 3 to 5% of all asthmatic patients and is histologically characterized by an increased bronchial smooth muscle (BSM) mass and clinically by viral exacerbations. Functionally, BSM remodeling had a poor prognostic value in asthma, since higher BSM mass was associated with lower lung function and increased exacerbation rate. However, the role of BSM as a potential actor of asthma exacerbation has only been sparsely suggested. Thus, we hypothesis that asthmatic BSM cell metabolism is modified compare to that of non-asthmatic and that could be a potential target to reduce asthmatic BSM cell proliferation and remodeling in asthma.

Project description:We report the application of RNA sequencing technology for high-throughput profiling of gene expression responses to human rhinovirus infection at 24 hours in air-liquid interface human airway epithelial cell cultures derived from 6 asthmatic and 6 non-asthmatic donors. RNA-seq analysis identified sets of genes associated with asthma specific viral responses. These genes are related to inflammatory pathways, epithelial remodeling and cilium assembly and function, including those described previously (e.g. CCL5, CXCL10 and CX3CL1), and novel ones that were identified for the first time in this study (e.g. CCRL1, CDHR3). We concluded that air liquid interface cultured human airway epithelial cells challenged with live HRV are a useful in vitro model for the study of rhinovirus induced asthma exacerbation, given that our findings are consistent with clinical data sets. Furthermore, our data suggest that abnormal airway epithelial structure and inflammatory signaling are important contributors to viral induced asthma exacerbation. Differentiated air-liquid interface cultured human airway epithelial cell mRNA profiles from 6 asthmatic and 6 non-asthmatic donors after 24 hour treatment with either HRV or vehicle control were generated by deep sequencing, using Illumina HiSeq 2000.

Project description:Murine Pulmonary Responses to Ambient Baltimore Particulate Matter: Genomic Analysis and Contribution to Airway Hyperresponsiveness; Asthma is a complex disease characterized by airway hyperresponsiveness (AHR) and chronic airway inflammation. Environmental factors such as ambient particulate matter (PM), a major air pollutant, has been demonstrated in epidemiological studies to contribute to asthma exacerbation and increased asthma prevalence. OBJECTIVE: We investigated the genomic and pathophysiological effects of Baltimore PM (median diameter 1.78 µm) in a murine model of asthma to identify potential biomarkers. METHODS: A/J mice with ovalbumin (OVA) âinduced AHR were exposed to PM (20 mg/kg, intratracheal), and both AHR and bronchoalveolar lavage (BAL) were assayed on days 1, 4, and 7 post exposure. Lung gene expression profiling (Affymetrix Mouse430_ 2.0) by PM (20 mg/kg, intratracheal) were assayed on OVA- and / or PM--challenged mice. RESULTS: Significant increases of airway responsiveness in OVA-treated mice were observed, indicating an asthmatic phenotype. Ambient PM exposure induced significant changes in AHR in both naive mice and OVA-induced asthmatic mice. In both naive and OVA challenged asthmatic mice, PM induced eosinophil and neutrophil infiltration into airways, elevated BAL protein content, and stimulated secretion of TH1 cytokines (IFN-g, IL-6, and TNF-a) and TH2 cytokines (IL-4, IL-5, and eotaxin) into BAL. Consistent with these results, PM induced expression of genes of innate immune response, chemotaxis and complementary system. CONCLUSION: These studies, consistent with epidemiological data, indicate that PM increases AHR and lung inflammation in naïve mice and exacerbates the asthma phenotype of increased AHR and gene expression pattern changes correlated with acute lung inflammation and airway damage. We used microarrays to detail the global programme of gene expression induced by rhPBEF treatment and VALI. Experiment Overall Design: animals were treated by PBS, Oval albumin, PM, or both OVA/PM

Project description:Although the nose, as a gateway for organism-environment interactions, may have a key role in asthmatic exacerbation, the rhinobiome of exacerbated children with asthma was widely neglected to date. Deep nasopharyngeal swab specimens, nasal epithelial spheroid cultures (NAEsp), and blood samples of acute exacerbated wheezers (WH), asthmatics (AB), and healthy controls (HC) were used for culture (n=146), 16 S-rRNA gene amplicon sequencing (n=64), proteomic and cytokine analyses. Interestingly, Proteobacteria were over-represented in WH (WH to AB: p=0.005; WH to HC: p=0.021), whereas Firmicutes and Bacterioidetes were associated with AB. In contrast, Actinobacteria commonly colonized HCs (PermANOVA p=0.005). Moreover, Staphylococcaceae (p<0.05), Enterobacteriaceae (p<0.05), Burkholderiaceae (p<0.05), Xanthobacteraceae (p<0.05), and Sphingomonadaceae (p<0.05) were significantly more abundant in AB compared to WH and HC. The α‐diversity analyses demonstrated an increase of bacterial abundance levels in atopic AB and a decrease in WH samples. Microbiome profiles of atopic WH differed significantly from atopic AB. The NAEsp bacterial exposure with M. catarrhalis, S. aureus and H. influenzae experiments provided a disrupted epithelial cell integrity, a cytokine release and cohort specific proteomic differences especially for M. catarrhalis cultures. Our comprehensive dataset contributes to a deeper insight into the poorly understood plasticity of the nasal microbiota, and, in particular, may enforce our understanding in the pathogenesis of asthma exacerbation in childhood.

Project description:Our study aimed to better understand the immune responses during an acute asthma exacerbation in children. Gene expression profiles were examined by RNA-sequencing in blood samples. Samples were collected on average 2.5 day after systemic corticosteroid treatment. Our findings show that pro-inflammatory genes and pathways related to innate responses and signaling remained increased in children hospitalized for acute asthma exacerbation. Genes and pathways involved in adaptive immune respones, particularly T lymphocyte activation, were decreased in children hospitalized for acute asthma exacerbation. These studies suggest that innate immune responses may remain activated following hospitalization for asthma exacerbation.
