Plasma proteomic, human Ebola virus disease

ABSTRACT: The 2013-2016 Ebola Zaire virus (EBV) outbreak in West Africa resulted in over 28,000 cases and 11,000 deaths. Ebola virus disease (EVD) is a highly virulent systemic disease with a high case fatality rate of ~ 50%. EVD results in hemorrhagic fever marked by an exaggerated systemic inflammatory response, and impaired vascular and coagulation systems. The immune response of patients who either survived or died is characterized by strong differences. Notably, fatalities showed a diminished capacity to mount an appropriate immune response, resulting in high viremia and increased pro-inflammatory cytokine production. In this study, we analyzed 38 sequential samples collected from 12 patients: 8 survivors and 4 fatalities. Our analytical strategy combined three protein-based platforms covering three different fractions of the plasma proteome: the undepleted classical plasma proteome, the depleted plasma proteome, and cytokines/chemokines, using LC/MS- and antibody-based assays, resulting in over 1000 quantified host and pathogen proteins. For depletion of the most abundant plasma proteins, we advanced a perchloric acid-based precipitation method. This method is low cost, high-throughput and robust.

Human sepsis with plasma samples

Project description:The project examines the mechanisms of neutrophil dysfunction during sepsis. Our work uncovered the central role of cell free circulating histones in eliminating mature neutrophil in favour of immature cells and characterized the mechanisms that regulate their release following systemic infection. Mature and immature neutrophil Ly6Ghigh and Ly6Glow populations isolated from the spleens of WT and TCRα-deficient mice either naïve or infected with C. albicans were characterized. In addition, these populations were compared to neutrophils isolated from WT mice receiving Clodronate-liposomes and recombinant G-CSF. These studies demonstrated that T-cell derived histones drive the release of G-CSF in the spleen and progressively eliminate mature neutrophils by shortening their lifespan. Finally, we conducted proteomic analysis of plasmas isolated from patients with microbial sepsis to correlate markers of neutrophil death to plasma cytokine and histone levels, confirming the pathogenic role these molecules play during sepsis in humans.

A time-resolved proteomic and prognostic map of COVID-19

Project description:We performed quantitative proteomic profiling of 786 plasma samples from COVID-19 inpatients, treated at two different hospitals (Charité – Universitätsmedizin Berlin and University Hospital of Innsbruck). Sampling was performed at multiple time points throughout the course of the disease, to create a time-resolved map of COVID-19 progression. Full DIA-NN analysis reports are provided, as well as raw files for the QC runs.

A proteomic survival predictor for COVID-19 patients in intensive care

Project description:Global healthcare systems are challenged by the COVID-19 pandemic. There is a need to optimize allocation of treatment and resources in intensive care, as clinically established risk assessments such as SOFA and APACHE II scores show only limited performance for predicting the survival of severely ill COVID-19 patients. Comprehensively capturing the host physiology, we speculated that proteomics in combination with new data-driven analysis strategies could produce a new generation of prognostic discriminators. We studied two independent cohorts of patients with severe COVID-19 who required intensive care and invasive mechanical ventilation. SOFA score, Charlson comorbidity index and APACHE II score were poor predictors of survival. Instead, using plasma proteomes quantifying 302 plasma protein groups at 387 timepoints in 57 critically ill patients on invasive mechanical ventilation, we found 14 proteins that showed trajectories different between survivors and non-survivors. A proteomic predictor trained on single samples obtained at the first time point at maximum treatment level (i.e. WHO grade 7) and weeks before the outcome, achieved accurate classification of survivors (AUROC 0.81, n=49). We tested the established predictor on an independent validation cohort (AUROC of 1.0, n=24). The majority of proteins with high relevance in the prediction model belong to the coagulation system and complement cascade. Our study demonstrates that predictors derived from plasma protein levels have the potential to substantially outperform current prognostic markers in intensive care.

Analysis of 1,508 plasma samples of the DiOGenes study - Robust, single shot capillary flow data-independent acquisition to decipher proteomic profiles of weight loss and maintenance

Project description:Based on our own experience and the evaluation of recent large-scale plasma mass spectrometry (MS) based proteomic studies (1, 2), we identified two outstanding challenges: slow and delicate nano-flow liquid chromatography (LC) and irreproducibility of identification of data-dependent acquisition (DDA). We determined a optimal solution reducing these limitations with robust capillary-flow data-independent acquisition (DIA) MS. This platform is capable of measuring 31 plasma proteomes per day. Using this setup, we acquired a large-scale plasma study of the diet, obesity and genes dietary (DiOGenes) comprising 1,508 samples.

Identification of Plasma Biomarkers from Rheumatoid Arthritis Patients Using an Optimized SWATH Proteomics Workflow

Project description:Rheumatoid arthritis (RA) is a systemic autoimmune and inflammatory disease. Plasma biomarkers are critical for understanding disease mechanisms, treatment effects, and diagnosis. Mass spectrometry-based proteomics is a powerful tool for unbiased biomarker discovery. However, plasma proteomics is significantly hampered by signal interference from high-abundance proteins, low overall protein coverage, and high levels of missing data from data-dependent acquisition (DDA). To achieve quantitative proteomic analysis for plasma samples with a balance of throughput, performance, and cost, we developed a workflow incorporating plate-based high abundance protein depletion and sample preparation, comprehensive peptide spectral library building, and data-independent acquisition (DIA) SWATH mass spectrometry-based methodology. In this study, we analyzed plasma samples from both RA patients and healthy donors. The results showed that the new workflow performance exceeded that of the current state-of-the-art depletion-based plasma proteomic platforms in terms of both data quality and proteome coverage. Proteins from biological processes related to the activation of systemic inflammation, suppression of platelet function, and loss of muscle mass were enriched and differentially expressed in RA. Some plasma proteins, particularly acute phase reactant proteins, showed great power to distinguish between RA patients and healthy donors. Moreover, protein isoforms in the plasma were also analyzed, providing even deeper proteome coverage. This workflow can serve as a basis for further application in discovering plasma biomarkers of other diseases.

Plasma proteome profiling discovers novel proteins associated with non-alcoholic fatty liver disease

Project description:Non-alcoholic fatty liver disease (NAFLD) affects 25% of the population and can progress to cirrhosis, where treatment options are limited. As the liver secrets most of the blood plasma proteins, its diseases should affect the plasma proteome. Plasma Proteome Profiling of 48 patients with cirrhosis or NAFLD, revealed eight significantly changing (ALDOB, APOM, LGALS3BP, PIGR, VTN, IGHD, FCGBP and AFM), two of which are already linked to liver disease. Polymeric immunoglobulin receptor (PIGR) was significantly elevated in both cohorts with a 2.7-fold expression change in NAFLD and 4-fold change in cirrhosis and was further validated in mouse models. Furthermore, a global correlation map of clinical and proteomic data strongly associated DPP4, ANPEP, TGFBI, PIGR, and APOE to NAFLD and cirrhosis. The prominent diabetic drug target DPP4 is an aminopeptidase like ANPEP, ENPEP and LAP3, which all upregulated in the human or mouse data. Furthermore, ANPEP and TGFBI have potential roles in extracellular matrix remodeling in fibrosis. Thus, Plasma Proteome Profiling can identify potential biomarkers and drug targets in liver disease.
