(Submitter supplied) Asthma exacerbations in children are associated with respiratory viral infection and atopy, resulting in systemic immune activation and infiltration of immune cells into the airways. The gene networks driving the immune activation and subsequent migration of immune cells into the airways remains incompletely understood. Cellular and molecular profiling of PBMC was employed on paired samples obtained from atopic asthmatic children (n = 19) during acute virus-associated exacerbations and later during convalescence. more...

(Submitter supplied) Severe asthma exacerbations in children requiring hospitalisation are typically associated with viral infection, and occur almost exclusively amongst atopics, but the significance of these comorbidities is unknown. We hypothesised that underlying interactions between immunoinflammatory pathways related to responses to aeroallergen and virus are involved, and that evidence of these interactions is detectable in circulating cells during exacerbations. more...

(Submitter supplied) Background: A subset of infants are hyper-susceptible to severe/acute viral bronchiolitis (AVB), for reasons unknown. Purpose: To characterise the cellular/molecular mechanisms underlying infant AVB in circulating cells/local airways tissues. Methods: PBMC and nasal mucosal scrapings (NMS) were obtained from Infants (<18mths) and children (1.5-5yrs) during AVB and post-convalescence. Immune response patterns were profiled by multiplex analysis of plasma cytokines, flow cytometry, and transcriptomics (RNA-Seq). more...

(Submitter supplied) 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.

(Submitter supplied) A large, prospective, non-interventional study was designed to study gene expression changes in peripheral blood mononuclear cells (PBMCs) associated with asthma exacerbations over the course of a year. PBMC samples were collected from subjects at the time of the study visits defined as 1) Quiet: during stable disease at 3 month intervals, 2) Exacerbation: during a 14 day period of deteriorating asthma and 3) Follow-up: within 14 days after cessation of an exacerbation. more...

(Submitter supplied) Allergic asthmatic, allergy only, asthma only (no allergy), and non-allergic non-asthmatic (control) subjects underwent bronchoscopy with instillation of saline, lipopolysaccharide (LPS), and house dust mite antigen in separate subsegmental bronchi. Airway epithelial cells were collected four hours later (three samples per subject). RNA was extracted from these cells for microarray analysis.

(Submitter supplied) DNA methylation profiling of airway epithelial cells (AECs) and peripheral blood mononuclear cells (PBMCs) from normal, atopic and asthmatic subjects. The Illumina GoldenGate Methylation Cancer Panel I was used to obtain DNA methylation profiles across approximately 1505 CpGs in AECs and PBMCs. Samples included 7 healthy, 9 atopic, 4 atopic asthmatic and 5 non-atopic asthmatic subjects. Please note that only some of the samples are matched (i.e. more...

(Submitter supplied) Comprehensive analyses of tissues at single-cell level will benefit our understanding of genetic bases for complex traits. Here we present an initial effort of single-cell transcriptomic analyses of cattle ruminal epithelial cells during the rumen development. We obtained 5064 and 1372 cells from Holstein ruminal epithelial cells before and after weaning, respectively. We reported 6 cell types across their temporal and spatial distributions, which were partially correlated with rumen epithelium layer’s structures and functions. more...

We performed single-cell RNA sequencing (scRNA-seq) analyses of peripheral blood mononuclear cells (PBMCs) from Holstein cattle, investigating their cell types and responses to lipopolysaccharide (LPS) treatment in vitro. The responses to LPS treatment include innate immunity activation of monocytes, macrophages, and dendritic cells, as well as B cell proliferation. more...

(Submitter supplied) Allergic (Th2high immunophenotype) asthmatics have a heightened susceptibility to common respiratory viral infections such as human rhinovirus. Evidence suggests that the innate interferon response is deficient in asthmatic/atopic individuals, whilst other studies show no differences in antiviral response pathways. Unsensitized and OVA-sensitized/challenged Th2high (BN rats) and Th2low immunophenotype (PVG rats) animals were inoculated intranasally with attenuated mengovirus (vMC0). more...
