Effects of the circulating environment of COVID-19 on platelet and neutrophil behavior

Project description:Thromboinflammatory complications are well described sequalae of Coronavirus Disease 2019 (COVID-19), and there is evidence of both hyperreactive platelet and inflammatory neutrophil biology that contributes to the thromoinflammatory milieu. It has been demonstrated in other thromboinflammatory diseases that the circulating environment may affect cellular behavior, but what role this environment exerts on platelets and neutrophils in COVID-19 remains unknown. We tested the hypotheses that 1) plasma from COVID-19 patients can induce a prothrombotic platelet functional phenotype, and 2) contents released from platelets (platelet releasate) from COVID-19 patients can induce a proinflammatory neutrophil phenotype. We treated platelets with COVID-19 patient and disease control plasma and found that COVID-19 patient plasma promoted auto-aggregation, thereby reducing response to further stimulation ex-vivo. Neither disease condition increased the number of platelets adhered to a collagen and thromboplastin coated parallel plate flow chamber, but both markedly reduced platelet size. We treated healthy neutrophils with COVID-19 patient and disease control platelet releasate and found that COVID-19 patient platelet releasate increased myeloperoxidase-deoxyribonucleic acid complexes and induced changes to neutrophil gene expression. Together these results suggest aspects of the soluble environment of COVID-19 stimulate circulating platelets, and that the contents released from those platelets can elicit inflammatory neutrophil behavior independent of direct cellular contact.

Spatial transcriptomics of post-mortem lung tissue from COVID-19 donors

Project description:Visualization of gene expression in lung tissue was performed using Visium spatial gene expression kits (10x Genomics) following the manufacturer`s protocol. The four capture areas in a 10x Genomics Visium Gene Expression slide consist of 5000 spots with DNA oligos for mRNA capture that have a unique spatial barcode and a unique Molecular Identifier (UMI). Each spot has 55 µm diameter and can therefore capture mRNA from 1 to 10 cells. We report the spatially resolved transcriptome of 3 control lung samples from non-COVID-19-related pneumonia donors and 9 COVID-19 lung samples analyzed with the 10x Visium platform.

Multi-omic analysis resolves coordinated immune responses to mild, moderate and severe COVID-19

Project description:This study utilizes multi-omic biological data to perform deep immunophenotyping on the major immune cell classes in COVID-19 patients. 10X Genomics Chromium Single Cell Kits were used with Biolegend TotalSeq-C human antibodies to gather single-cell transcriptomic, surface protein, and TCR/BCR sequence information from 254 COVID-19 blood draws (a draw near diagnosis (-BL) and a draw a few days later (-AC)) and 16 healthy donors.

Immunophenotyping of COVID-19 and Influenza Underscores the Association of Type I IFN Response in Severe COVID-19

Project description:Although most SARS-CoV-2-infected individuals experience mild COVID-19, some patients suffer from severe COVID-19, which is accompanied by acute respiratory distress syndrome and systemic inflammation. To identify factors driving severe progression of COVID-19, we performed single-cell RNA-seq using peripheral blood mononuclear cells (PBMCs) obtained from healthy donors, patients with mild or severe COVID-19, and patients with severe influenza. Patients with COVID-19 exhibited hyper-inflammatory signatures across all types of cells among PBMCs, particularly upregulation of the TNF/IL-1beta-driven inflammatory response as compared to severe influenza. In classical monocytes from patients with severe COVID-19, type I IFN response co-existed with the TNF/IL-1beta-driven inflammation, and this was not seen in patients with milder COVID-19 infection. Based on this, we propose that the type I IFN response exacerbates inflammation in patients with severe COVID-19 infection.

PLATELET PROTEOME REVEALS FEATURES OF CELL DEATH, ANTIVIRAL RESPONSE AND VIRAL REPLICATION IN COVID-19.

Project description:This article provides the first proteomic analysis of platelets from COVID-19 patients. Our dataset shows that platelets are reprogrammed during severe COVID-19 and respond with the activation of type I interferon and cell death pathways, indicating platelet participation in the antiviral response. Additionally, identification of proteins involved in translation, mainly in non-surviving, and complete sequencing of SARS-CoV-2 genome call attention to platelets as viral repositories and markers poor prognosis in COVID-19.

Multiple Early Factors Anticipate Post-Acute COVID-19 Sequelae

Project description:Post-acute sequelae of COVID-19 (PASC) represent an emerging global crisis. However, quantifiable risk-factors for PASC and their biological associations are poorly resolved. We executed a deep multi-omic, longitudinal investigation of 309 COVID-19 patients from initial diagnosis to convalescence (2-3 months later), integrated with clinical data, and patient-reported symptoms. We resolved four PASC-anticipating risk factors at the time of initial COVID-19 diagnosis: type 2 diabetes, SARS-CoV-2 RNAemia, Epstein-Barr virus viremia, and specific autoantibodies. In patients with gastrointestinal PASC, SARS-CoV-2-specific and CMV-specific CD8+ T cells exhibited unique dynamics during recovery from COVID-19. Analysis of symptom-associated immunological signatures revealed coordinated immunity polarization into four endotypes exhibiting divergent acute severity and PASC. We find that immunological associations between PASC factors diminish over time leading to distinct convalescent immune states. Detectability of most PASC factors at COVID-19 diagnosis emphasizes the importance of early disease measurements for understanding emergent chronic conditions and suggests PASC treatment strategies.

Proteome of extracellular vesicles from plasma of COVID-19 patients

Project description:Background: Extracellular vesicles are a valuable source of biomarkers and display the pathophysiological status of various diseases. In COVID-19, EVs are explored in several studies for their ability to reflect molecular changes caused by SARS-CoV-2 infection and impacts on disease progression. Methods: In this study, we used a label-free shotgun proteomics approach to identify and quantify any alterations in EVs proteins abundance in severe COVID-19 patients. We isolated plasma extracellular vesicles from healthy donors and patients with severe COVID-19 by size exclusion chromatography (SEC). Then, flow cytometry was performed to assess the origin of EVs and investigate the presence of circulating procoagulant EVs in COVID-19 patients. A total protein extraction was performed and samples were analyzed by nLC-MS/MS in a Q-Exactive HF-X. Finally, computational analyzes were applied to sign biological processes related to disease pathogenesis. Results: We report significant changes in the proteome of EVs from patients with severe COVID-19. Differently expressed proteins in the disease groups were associated with platelet degranulation, integrin cell surface interaction, and acute inflammatory response. Flow cytometry experiments indicated an increase in total circulating EVs and with TF-dependent procoagulant activity.
