Project description:Interstitial lung disease (ILD) is a group of respiratory disorders characterized by chronic inflammation and fibrosis of the pulmonary interstitial tissues. Although the etiology of ILD remains unclear, some drug treatments are one of the primary causes of ILD. In the present study, we analyzed FDA Adverse Event Reporting System and JMDC insurance claims to find a coexisting drug that reduced the incidence of ILD associated with use of an anti-arrhythmic agent, amiodarone, and found that the thrombin inhibitor dabigatran prevented the amiodarone-induced ILD in both clinical datasets. In an experimental validation of the hypothesis, a long-term, oral treatment of mice with amiodarone caused a gradual decrease in the body weight caused by respiratory insufficiency. In the lung of amiodarone-treated mice, infiltration of macrophages and interstitial thickening were observed in parallel with a delayed upregulation of platelet-derived growth factor receptor α gene. In contrast, co-treatment with dabigatran significantly attenuated these amiodarone-induced changes representing ILD. These results suggest that dabigatran is effective in preventing the drug-induced ILD. This combinatorial approach of drug repositioning based on clinical big data will pave the way for finding a new treatment with high clinical predictability and a well-defined molecular mechanism.
Project description:RNAseq analysis of human lung slices after treatment with different interferons. Results: Differentially expressed genes were observed after treatment with different interferons. Methods: Tumor-free human lung explants were obtained from patients undergoing lung surgery at the University Hospital Muenster on the day of surgery. Tissue blocks were individually placed in a 12-well plate in RPMI medium. Tissues were treated with different interferons. RNA was prepared from tissue homogenates.

Project description:IIn contrast to the young mice treated with anti-PD-1 therapy, aged mice exhibited immune-related adverse event (irAE)-like symptoms in the lung when treated with anti-PD-1 therapy. To understand the molecular events underlying the development of anti-PD-1 therapy-induced irAE, we employed deep RNA sequencing of whole lung transcript from anti-PD-1 therapy-treated young and aged mice. In order to further evaluate the effect of IL-21 signal on PD-1-blockade-mediated immune response, gene expression profile in lung tissue from aged mice twith the blockade of IL-21 activity was also assessed.
Project description:Fra-2tg mice develop spontaneous lung fibrosis. We carried out this sequencing with tissue from young animals before they develop the tissue fibrosis, to explore the early gene expression changes that might contribute to the phenotype.
