(Submitter supplied) Pulmonary fibrosis develops as a consequence of environmentally induced lung injury and/or an inherent disease susceptibility causing fibroblast activation, proliferation and extracellular matrix deposition. The study was undertaken to characterise global gene expression in pulmonary fibroblasts to better understand the mechanisms underlying the fibrotic fibroblast phenotype.

(Submitter supplied) Myofibroblasts are key effector cells in the extracellular matrix remodeling of systemic sclerosis-associated interstitial lung disease (SSc-ILD), however the diversity of fibroblast populations present in the healthy and SSc-ILD lung is unknown, and has prevented the specific study of the myofibroblast transcriptome. We sought to identify and define the transcriptomes of myofibroblasts and other mesenchymal cell populations in human healthy and SSc-ILD lungs to understand how alterations in fibroblast phenotypes lead to SSc-ILD fibrosis.

(Submitter supplied) Idiopathic pulmonary fibrosis (IPF) and systemic sclerosis-associated interstitial lung disease (SSc-ILD) differ in the predominant demographics and identified genetic risk alleles of affected patients, however both diseases frequently progress to respiratory failure and death. Contrasting advanced SSc-ILD to IPF provides insight to the role dysregulated immunity may play in pulmonary fibrosis. To analyze cell-type specific transcriptome commonalities and differences between IPF and SSc-ILD, we compared single-cell RNA-sequencing (scRNA-seq) of 21 explanted lung tissue specimens from patients with advanced IPF, SSc-ILD, and organ donor controls. more...

(Submitter supplied) Objective: Pulmonary complications in systemic sclerosis (SSc), including pulmonary fibrosis (PF) and pulmonary arterial hypertension (PAH), are the leading cause of mortality. We compared the molecular fingerprint of SSc lung tissues and matching primary lung fibroblasts to those of normal donors, and patients with idiopathic pulmonary fibrosis (IPF) and idiopathic pulmonary arterial hypertension (IPAH). more...

(Submitter supplied) Objective: MicroRNAs (miRNAs) control key elements of mRNA stability and likely contribute to the dysregulated lung gene expression observed in systemic sclerosis associated interstitial lung disease (SSc-ILD). We analyzed the miRNA gene expression of tissue and cells from SSc-ILD patients. A chronic lung fibrotic murine model was used. Methods: RNA was isolated from lung tissue of 12 SSc-ILD patients and 5 control lungs. more...

(Submitter supplied) Systemic sclerosis (SSc) is a rare but devastating disease of fibrosis impacting the dermis and multiple organ systems. The prevalence ranges from 4 to 489 cases per million individuals with ten year mortality rates reported around 18 percent. Survival is related to the extent of skin involvement, yet the precise mechanisms driving skin fibrosis in SSc remain unknown. In this study, we analyzed the shared and unique transcriptomic profiles of SSc and normal keratinocytes.

We undertook this study to analyze the gene expression of lung tissue in a prospective cohort of patients with SSc-related ILD and to compare it with that in control lungs and with 2 prospective clinical parameters in order to understand the molecular pathways implicated in progressive lung disease. more...

(Submitter supplied) Systemic sclerosis-associated interstitial lung disease (SSc-ILD) is the leading cause of death in patients with systemic sclerosis (SSc) with unclear pathogenesis and limited treatment options. Evidence strongly supports an important role for profibrotic, SPP1-expressing macrophages in SSc-ILD. We sought to define the transcriptome and chromatin structural changes of SPP1 SSc-ILD macrophages, so as to better understand their role in promoting fibrosis and to identify transcription factors associated with open chromatin driving their altered phenotype.

(Submitter supplied) Recent publications have implicated senescent alveolar epithelial cells as the cause of lung remodeling and fibrosis. We sought to better understand the heterogeneity in the basal epithelial cell population, especially with regards to characterizing senescent alveolar epithelial cells. The basal cell cultures contain a portion of cells that display a senescent phenotype and stain for a marker of senescence. more...

(Submitter supplied) We characterized senescent alveolar epithelial cells in an effort to better understand how these cells contribute to lung remodeling and fibrosis. The transcriptional profiles of several different types of senescent lung epithelial cells was evaluated using various induction methods in order to better understand core characteristics associated with the senescent program in epithelial cells of the lung.

(Submitter supplied) Epithelial senescence, specifically in the bronchiolized regions of the fibrotic lung, is apparent in IPF but not control tissue. In order to better understand the phenotype of these senescent cells we generated a in vitro culture model of senescence utillizing primary normal human bronchial epithelial cells. Cultures were treated with doxorubicin to induce senescence and the transcriptional phenotype of the senescent cultures was compared to DMSO-treated control cultures.

(Submitter supplied) To understand the cellular composition and transcriptional phenotype of fibrotic lung tissue we performed single-cell RNA-seq on stromal, immune, epithelial, and endothelial cell populations from human lung explants. Tissue was collected from normal control lungs, patients with idiopathic pulmonary fibrosis (IPF), and patients with systemic sclerosis associated interstitial lung disease (SSc-ILD). Using the 10X Genomics Chromium platform, we generated transcriptional profiles of approximately 200,500 cells across 4 IPF, 3 SSc-ILD and 3 normal control lungs.
