Validation of detected viral and host peptides from COVID-19 nasopharyngeal swab samples

ABSTRACT: In the current scenario of COVID-19, an assay that can efficiently and specifically detect infection by SARS-COV2 is required. Nasopharyngeal swabs are non-invasive samples and can be conveniently acquired from the population to be screened. In this work, we have validated a few viral and host peptides (found to be relevant from our shotgun data) using a Triple Quadrupole mass spectrometer.

The altered molecular proteins and pathways in response to COVID-19 infection are still unclear. Here, we performed a comprehensive proteomics-based investigation of nasopharyngeal swab samples from patients with COVID-19 to study the host response by employing simple extraction strategies. Few of the host proteins such as interleukin-6, L-lactate dehydrogenase, C-reactive protein, Ferritin, and aspartate aminotransferase were found to be upregulated only in COVID-19-positive patients using targ ...[more]

DIA-based proteome profiling of nasopharyngeal swabs from COVID-19 patients

Project description:We sought to characterize the host response through proteome profiling of nasopharyngeal swab specimens. A mass spectrometer combining trapped ion mobility spectrometry and high-resolution QTOF mass spectrometer with a parallel accumulation-serial fragmentation (PASEF) was deployed for unbiased proteome profiling. First, deep proteome profiling of nasopharyngeal swabs was performed in PASEF-DDA mode, which identified 7,723 proteins and 102,392 peptides that were then used for constructing a spectral library. Subsequently, quantitative proteome profiling was carried out for 90 nasopharyngeal swab samples in diaPASEF mode which resulted in 5,023 protein identifications. Functional analysis revealed two significant features of biological processes of innate immune response and viral life cycle. Overall, we provide the in-depth proteome record from nasopharyngeal swab samples and suggest relevant host response along with proteins playing a pivotal role against viral infection, which would assist for mining promising drug targets in the future.

RNA-seq analysis of nasopharyngeal swabs from asymptomatic and mildly symptomatic COVID-19 patients

Project description:We used total RNA of nasopharyngeal swabs from COVID-19 patients to identify their gene expression profile. Multiple biological process were significantly enriched in either asymptomatic or mildly symptomatic patients. These significantly expressed genes were suggested to contribute to the severity of the disease. We also performed metagenomics analysis to identify differences in the microbiome profile of the two groups of patients.

Proteomic analysis of SARS-CoV-2: A clinical landscape of COVID-19 proteome and host responses

Project description:A novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of COVID-19 and continues to be a global health challenge. To understand viral disease biology, we have carried out proteo-genomic analysis using next generation sequencing (NGS) and mass-spectrometry on nasopharyngeal swabs of COVID-19 patients to examine clinical genome and proteome. Our proteomic analysis, for the first time identified 13 different SARS-CoV-2 proteins from the clinical swabs. Additionally, host proteome analysis revealed several key host proteins to be uniquely expressed in COVID-19 patients. Besides revealing aspects of host-virus pathogenesis, our study opens avenues to develop better diagnostic markers and therapeutic strategies.

A diagnostic host response biosignature for COVID-19 from RNA profiling of nasal swabs and blood

Project description:To elucidate key pathways in the host transcriptome of patients infected with SARS-CoV-2, we used RNA sequencing (RNA Seq) to analyze nasopharyngeal (NP) swab and whole blood (WB) samples from 333 COVID-19 patients and controls, including patients with other viral and bacterial infections. Analyses of differentially expressed genes (DEGs) and pathways was performed relative to other infections (e.g. influenza, other seasonal coronaviruses, bacterial sepsis) in both NP swabs and WB. Comparative COVID-19 host responses between NP swabs and WB were examined. Both hospitalized patients and outpatients exhibited upregulation of interferon-associated pathways, although heightened and more robust inflammatory and immune responses were observed in hospitalized patients with more clinically severe disease. A two-layer machine learning-based classifier, run on an independent test set of NP swab samples, was able to discriminate between COVID-19 and non-COVID-19 infectious or non-infectious acute respiratory illness using complete (>1,000 genes), medium (<100) and small (<20) gene biomarker panels with 85.1%-86.5% accuracy, respectively. These findings demonstrate that SARS-CoV-2 infection has a distinct biosignature that differs between NP swabs and WB and can be leveraged for differential diagnosis of COVID-19 disease.

SARS-CoV-2 produces a microRNA, CoV2-miR-O8, in patients with COVID-19 infection

Project description:SARS-CoV-2 can generate viral microRNAs (v-miRNAs) that target host gene expression. This study used small RNAseq to identify the v-miRNAs present in COVID-19 patients' nasopharyngeal swabs. The study identified a specific conserved v-miRNA sequence (CoV2-miR-O8) unique to SARS-CoV-2 that is highly present in COVID-19 patients' samples, interacts with Argonaute, and has features consistent with Dicer and Drosha generation. CoV2-miR-O8 is predicted to target specific human genes and can be detected by RTPCR assays in patients.

PROTEOMICS EVOLUTION FROM ACUTE TO POST-COVID-19 CONDITION

Project description:We performed longitudinal plasma proteomics analysis and determined absolute protein levels in a Canadian cohort (n=74) at admission day to hospital for acute COVID-19 and at 3 and 6 months after diagnosis of acute COVID-19. We measured plasma protein on a triple quadrupole mass spectrometer operated in multiple reaction monitoring mode and used internal standards to deduce protein absolute concentrations. We used a validated panel of 269 surrogate heavy labeled peptides. We also measured % predicted forced vital capacity (FVC, %) and diffusing capacity of the lungs for carbon monoxide (DLCO, %) by routine pulmonary function testing. We did functional enrichment and pathway analyses and determined proteins that were increased or decreased from hospital admission to 3-months and 6-months, compared females to males and determined associations of proteins with FVC% and DLCO%.
