Project description:Mild asthmatics who met the criteria of the IRB approved protocol of Sub-segmental Bronchial Provocation with Allergen were recruited. The subjects were challenged with sensitive allergen through bronchoscopy. Bronchoalveolar lavage (BAL) fluids were collected before and at 48 hours after allergen challegen. From the BAL fluids, alveolar macrophages were purifed and their RNA was extracted. Total 138 genes including five house keeping genes were evaluated.
Project description:RNA was extracted from the meninges of mice from either Specific pathogen free or Germ free facilities or from the offspring of mice reconstituted with different human microbiomes.
Project description:Exsome microRNA stably present in various body fluids (such as amniotic fluid, breast milk, blood, bronchial lavage, malignant ascites fluid, tears, saliva, and urine) shown to be associated with various pathological conditions. We report the microRNA expression profiles in porcine serum, plasma, semen, urine and bile exsome at postnatal 180-days-old by a deep sequencing technology.
Project description:Mild asthmatics who met the criteria of the IRB approved protocol of Sub-segmental Bronchial Provocation with Allergen were recruited. The subjects were challenged with sensitive allergen through bronchoscopy. Bronchoalveolar lavage (BAL) fluids were collected before and at 48 hours after allergen challegen. From the BAL fluids, alveolar macrophages were purifed and their RNA was extracted. Total 138 genes including five house keeping genes were evaluated. Two samples of alveolar macrophages from single subject, before and 48 hours after allergen challenge, were directly compared in terms of the expression of inflammatory, chemokine, cytokine genes and their receptor genes.
Project description:HuMiChip2 was applied to analyze perform both strain-level identification and the functional profiling of human gut microbiomes from alcoholic cirrhosis patients and healthy individuals with alcohol abuse.
Project description:We performed single cell RNA sequencing on bronchial cells from human bronchoalveolar lavage fluid from 4 independent study participants who had asthma and who underwent lung segmental allergen challenge with diluent or allergen (either house duse mite or cat). The goal was to assess total mRNAs in single cell preparations of bronchoalveolar lavage cells.
Project description:Bronchial Epithelial Cells were isolated processed as described (Chu et al., 2002 and Zhao et al., 2011). The objective of the study was to identify differentially expressed genes between normal control (NC), mild-moderate asmathic (notSA) and severe asthmatic (SA) patients. For demographics data, contact Dr. Sally Wenzel (wenzelse@upmc.edu) Bronchoscopy with endobronchial epithelial brushing was performed as previously described (Chu et al., 2002; Zhao et al., 2011). Bronchial alveolar lavage fluids were spun down on 4000 g for 10 minutes. 0.5- 1X10^6 cells were stored in Trizol for RNA extraction. RNA in Trizol solution was extracted using the QIACube system (Qiagen, Valencia, CA). RNA quality was determined using the Agilent Bioanalyzer 2100 (Agilent Technologies, Santa Clara, CA), and only samples with an RIN higher than 7 used for microarray experiments.
Project description:Aspergillus fumigatus mutant strains were collected from bronchoalveolar lavage fluids (BALFs) during acute mouse infection (4 and 12 hours).
