Project description:Purpose: The goal of this study is to investigate the alteration of gene expression pattern of alveolar macrophages by allergen challenge in human asthmatics. Method: By using subsegmental bronchial provocation with allergen (SBP-AG) protocol, we obtained BAL fluids, before and 48 hours after allergen challenge in the subjects enrolled in the protocol. Alveolar macrophages were purified from the BAL fluids and total RNA was isolated. Next-generation sequencing data were generated by using the Illumina system. Results: Using an optimized data analysis workflow, we mapped about 75 million sequence reads per sample to the human genome and identified 29,691 transcripts in the macrophage mRNAs. Among them, the change in the expression profiles of 37 transcripts were statistically significant. Conclusions: It has been well accepted that Th2 cytokine enriched environment transforms the phenotype of macrophages into alternatively activated form. However, the details of a genome-wide gene expression profiles of macrophages were not well investigated. Using RNA-seq technology, we provided comprehensive data of macrophage gene expression profiles in allergic lung inflammation. Our data could offer a framework to study biologic functions of alternatively activated macrophage in chronic inflammatory diseases. mRNA profiles of alveolar macrophages obtained from asthmatics, before and after allergen challenge.

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.
