Project description:Analysis of nasal epithelial cells from adult patients with seasonal allergic rhinitis and from non allergic controls. Results provide insight into the molecular mechanisms associated with inflammatory responses in nasal mucosa. Total RNA was obtained from nasal epithelial cells of 7 seasonal allergic rhinitis patients and 5 non-allergic control subjects

Project description:Seasonal allergic rhinitis (SAR) is a complex disease that is caused by many interacting genes and environmental factors. It is also an excellent model disease for clinical studies; it is common, it is seasonal, and since it takes place in the nasal cavity it can be studied in vivo non-invasively. Furthermore, the key disease cell, the Th2 cell is known. We study SAR using allergen-challenged CD4+ cells from allergic patients.

Project description:To explore the impact of nasal commensal viruses on the onset and progression of allergic rhinitis, We used single cell RNA sequencing (scRNA-seq) to analyze the diversity of CD45+ cells in the nasal mucosa of mice treated with Vehicle, Ribavirin, Vehicle-OVA, or Ribavirin-OVA.

Project description:To elucidate the epithelial cell diversity within the nasal inferior turbinates, a comprehensive investigation was conducted comparing control subjects to individuals with house dust mite-induced allergic rhinitis. This study aimed to delineate the differential expression profiles and phenotypic variations of epithelial cells in response to allergic rhinitis. This research elucidated distinct subpopulations and rare cell types of epithelial cells within the nasal turbinates, discerning alterations induced by allergic rhinitis. Furthermore, by interrogating transcriptomic signatures, the investigation provided novel insights into the cellular dynamics and immune responses underlying allergic rhinitis pathogenesis

Project description:For analyzing the exploratory nasal commensal viruses, we performed the metatranscriptomic analysis of the nose swabs from the enrolled AR patients both before and after treatments, as well as sequenced the nose swabs from a set of healthy volunteers without AR history.Simultaneously, to assess the expression of interferon-stimulated genes in patients with allergic rhinitis, we analyzed the gene expression of host reads.

Project description:Purpose: Ipratropium bromide (IB) is able to ameliorate symptoms of allergic rhinitis (AR) by neuroimmunologic mechanism. We intended to explorer whether IB induced effect through modulating specific alteration of miRNA profiling or not. Methods: Nasal sRNAs (miRNAs) profiles of control mice and OVA-induced AR mice that were pre-treated with IB or normal saline before intranasal OVA challenge for 2 or 4 weeks were generated by high-throughput sequencing using Illumina Hiseq 2000.Raw data for sRNA (miRNA) profiles were processed to obtain corresponding clean data which were mapped to reference sequence(mm10) by TopHat(v2.0.9).The expression levels for these resulting mapped miRNAs were estimated by TPM (transcript per million),afterwards, the differentially expressed miRNAs were identified, and the candidate allergic-related miRNAs were further determined by RT-qPCR. Results: Using an optimized data analysis workflow,our data showed that in nasal mucosa of allergic mice with ipratropium bromide (IB) treatment 87 miRNAs are differentially expressed whereas in the nasal mucosa of non-allergic mice 113 miRNAs are differentially expressed, when compared with allergic mice treated with normal saline.IB treatment significantly up-regulated the levels of mmu-miR-124-3p/5p, -133b-5p, -133a-3p/5p, -384-3p, -181a-5p, -378a-5p, -3071-5p. RT-qPCR data further validated these miRNAs expression. Conclusions: Our study represents the detailed analysis of nasal mucosa miRNAs profiles of OVA-induced allergic mice treated with IB, generated by RNA-seq technology. Moreover, IB treatment orchestrated expression of allergic immune-related miRNAs of nasal mucosa in allergic mice, which may associate with ameliorated nasal allergic symptoms

Project description:Background: In asthma, airway epithelium remodeling can already be detected during childhood, and epithelial cells are more susceptible to virus and oxidative stress. Their exact role in natural history and severity of children allergic respiratory disease remains however surprisingly unexplored. Aim: To analyze dysfunctions of epithelium in dust mite allergic respiratory disease (rhinitis ± asthma) in children. Methods: Expression profilings of nasal epithelial cells collected by brushing were performed on Affymetrix Hugene 1.0 ST arrays. All allergic patients were sensitized to dust mite. 19 patients had an isolated allergic rhinitis (AR). 14 patients had AR associated with asthma. Patients were compared to 12 controls, their severity and control being assessed according to NAEPP and ARIA criteria. Infections by respiratory viruses were excluded by real-time PCR measurements. Results: 61 probes were able to distinguish allergic rhinitis children from healthy controls. A majority of these probes was under the control of Th2 cytokines, as evidenced by parallel experiments performed on primary cultures of nasal epithelial cells. In uncontrolled asthmatic patients, we observed not only an enhanced expression of these Th2-responsive transcripts, but also a down-regulation of interferon-responsive genes. Conclusion: Our study identifies a Th2 driven epithelial phenotype common to all dust mite allergic children. Besides, it suggests that epithelium is involved in the severity of the disease. Expression profiles observed in uncontrolled asthmatic patients suggest that severity of asthma is linked at the same time to atopy and to impaired viral response. Nasal epithelium gene expression profiling of dust mite allergic children with isolated rhinitis, rhinitis associated with asthma and controls. 38 samples classified in 4 categories : 14 isolated rhinitis (R), 6 rhinitis with uncontrolled asthma (UA), 7 rhinitis with controlled asthma (CA) and 11 healthy subjects (C )

Project description:This study investigated temporal transcriptomic changes in response to nasal allergen challenge of titrated timothy grass pollen. This is an open single-center observational study conducted outside the pollen season. Twelve participants with seasonal allergic rhinitis underwent a control (diluent) challenge followed by nasal allergen challenge after an interval of 14 days. On each challenge day, nasal challenge with control or titrated timothy grass pollen (Aquagen, phleum pratense; ALK) was administered. Peripheral blood was collected before nasal challenge (baseline) and at 3, 6 and 24 hours following challenge. RNA was extracted from whole blood and CD4 cells for microarray experiment using Affymetrix Human Gene 1.0 ST arrays.
