Project description:Some patients infected with Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) develop severe pneumonia and the acute respiratory distress syndrome (ARDS). Distinct clinical features in these patients have led to speculation that the immune response to virus in the SARS-CoV-2-infected alveolus differs from other types of pneumonia. We collected bronchoalveolar lavage fluid samples from 88 patients with SARS-CoV-2-induced respiratory failure and 211 patients with known or suspected pneumonia from other pathogens and subjected them to flow cytometry and bulk transcriptomic profiling. We performed single-cell RNA-seq on 10 bronchoalveolar lavage fluid samples collected from patients with severe COVID-19 within 48 hours of intubation. In the majority of patients with SARS-CoV-2 infection, the alveolar space was persistently enriched in T cells and monocytes. Bulk and single-cell transcriptomic profiling suggested that SARS-CoV-2 infects alveolar macrophages, which in turn respond by producing T cell chemoattractants. These T cells produce interferon-gamma to induce inflammatory cytokine release from alveolar macrophages and further promote T cell activation. Collectively, our results suggest that SARS-CoV-2 causes a slowly-unfolding, spatially-limited alveolitis in which alveolar macrophages harboring SARS-CoV-2 and T cells form a positive feedback loop that drives persistent alveolar inflammation.

Project description:Acute Respiratory Distress Syndrome (ARDS) remains a significant clinical challenge, with its pathogenesis not fully understood. Proteomic analyses of plasma and bronchoalveolar lavage fluid (BALF) in patients with ARDS have been performed to uncover diagnostic and prognostic markers, although previous studies have not adequately focused on longitudinal biomarker comparison. This study aims to elucidate the proteomic profiles of patients with ARDS in acute and subacute phases to better understand pathophysiological progression of ARDS.

Project description:Hyperinflammation contributes to lung injury and subsequent acute respiratory distress syndrome (ARDS) with high mortality in severe COVID-19. To understand the underlying mechanisms, we investigated the role of the lung-specific immune response. Here we profiled lymphocytes and myeloid cells in the bronchoalveolar lavage (BAL) fluid and blood of COVID-19 patients. By tracking T cell clones across tissues, we identified clonally expanded tissue-resident memory-like Th17 cells (Trm17 cells) in the lung even after viral clearance. These Trm17 cells are characterized by a potentially pathogenic cytokine profile with expression of IL17A and CSF2 (GM-CSF). Interactome analysis revealed that Trm17 cells interact with macrophages and cytotoxic CD8+ T cells, which have been associated with disease severity and lung damage. High IL-17A and GM-CSF protein levels in the serum of COVID-19 patients correlated with severe clinical course. This study suggests pulmonary Trm17 cells as one of the orchestrators of the hyperinflammation in severe COVID-19 and that these cells and their cytokines, such as GM-CSF, are promising biomarkers and potential targets for a COVID-19 therapy.

Project description:Influenza A virus (IAV) causes severe respiratory infections and alveolar epithelial damage resulting in acute respiratory distress syndrome (ARDS). Extracellular vesicles (EV) have been shown to mediate cellular crosstalk in inflammation by transfer of microRNAs. In this study, we found significant changes in the miRNA composition of EVs in the broncho-alveolar lavage fluid (BALF) from patients with IAV-induced ARDS. Among the nine significantly deregulated microRNAs, miR-17-5p was upregulated in patients` BALF and in EVs of IAV-infected lung epithelial cells (A549). In these cells, transfer of miR-17-5p strongly downregulated expression of the antiviral factor Mx1 and significantly enhanced IAV replication.

Project description:Bronchoalveolar lavage fluid (BALF) collected from mice with and without the induction of Acute Respiratory Distress Syndrome (ARDS) and treated with engineered extracellular vesicles (EVs). BALF extracts were analyzed by LC-MS/MS performed in an 6545 Q-TOF LC/MS (AGILENT) using a Poroshell 120 SB-C18 reversed phase column (2.1 x 100 mm, 2.7 um). (NEGATIVE mode)

Project description:Obesity is associated with increased risk for acute respiratory distress syndrome (ARDS). High fat diet induced obesity was linked to increased lung injury and bronchoalveolar lavage fluid (BALF) free fatty acids in a hyperoxic model of ARDS. In this study, we show significant transcriptional downregulation of fatty acid oxidation (FAO), the mitochondrial process of breaking down fatty acids, in alveolar epithelial type 2 cells (AEC2) of obese compared to lean mice after hyperoxia. AEC2 from obese mice exhibited increased intracellular lipids, more severe mitochondrial bioenergetic failure and reduced ATP production after hyperoxia compared to lean mice. FAO downregulation in AEC2 through a genetic mouse model targeting carnitine palmitoyltransferase 1A (Cpt1aloxp/loxpSftpcCreERT2+/– mice) resulted in further increased BALF fatty acids and lung injury in obese mice. High fat diet was associated with markers of impaired alveolar epithelial regeneration after hyperoxia, which include reduced surfactant AEC2 lineage markers, as well as reduced surfactant related phospholipids in hyperoxic AEC2, and increased BALF surface tension. In a reanalysis of a human molecular single-cell lung atlas of COVID19 ARDS, significant downregulation of the FAO signature in AEC2 compared to controls was observed only in ARDS patients with BMI >30, and not those with BMI <30.

Project description:Bronchoalveolar lavage samples collected from lung transplant recipients. Numeric portion of sample name is an arbitrary patient ID and AxBx number indicates the perivascular (A) and bronchiolar (B) scores from biopsies collected on the same day as the BAL fluid was collected. Several patients have more than one sample in this series and can be determined by patient number followed by a lower case letter. Acute rejection state is determined by the combined A and B score - specifically, a combined AB score of 2 or greater is considered an acute rejection.
