Abstract

Dysregulated immune responses against the SARS-CoV-2 virus are instrumental in severe COVID-19. However, the immune signatures associated with immunopathology are poorly understood. Here we use multi-omics single-cell analysis to probe the dynamic immune responses in hospitalized patients with stable or progressive course of COVID-19, explore V(D)J repertoires, and assess the cellular effects of tocilizumab. Coordinated profiling of gene expression and cell lineage protein markers shows that S100A hi /HLA-DR lo classical monocytes and activated LAG-3 hi T cells are hallmarks of progressive disease and highlights the abnormal MHC-II/LAG-3 interaction on myeloid and T cells, respectively. We also find skewed T cell receptor repertories in expanded effector CD8 + clones, unmutated IGHG + B cell clones, and mutated B cell clones with stable somatic hypermutation frequency over time. In conclusion, our in-depth immune profiling reveals dyssynchrony of the innate and adaptive immune interaction in progressive COVID-19.

    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    The relatively small sample size (18 COVID-19 samples and 13 controls) is a limitation of this study, especially for the analysis of certain subgroups (e.g. only four samples from patients who did not receive tocilizumab). However, it is larger than most COVID-19 scRNAseq studies published to-date17,83,84,96, and the similarity of baseline characteristics between stable and progressive patients and in comparison, to controls (Table 1) helps increase confidence in our results. Although the timing of blood draw A (time-point A) relative to hospitalization was consistent across subjects, the timing of blood draw B (time-point B) was variable. We mitigated that by taking into account the variable time span between the two blood draws in some of the analyses, e.g. for the analysis of IFN score changes over time shown in Fig 3A & B. This unique exploration of gene expression changes over time adds an essential dynamic layer that is critical to understand the biology of an acute viral disease. Lastly, our analysis mostly relied on RNA-based analyses including gene expression and TCR/BCR repertoire analysis, with some protein-level validation by CITE-seq and flow cytometry. Additional mechanistic validation, while beyond the scope of this study, is warranted in future studies. In conclusion, our in-depth multi-omics assessment of peripheral immune cells at single-cell resolution across patient severities and time highlights the desynchronized adaptive and innate immune response in pr...

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore is not a substitute for expert review. SciScore checks for the presence and correctness of RRIDs (research resource identifiers) in the manuscript, and detects sentences that appear to be missing RRIDs. SciScore also checks to make sure that rigor criteria are addressed by authors. It does this by detecting sentences that discuss criteria such as blinding or power analysis. SciScore does not guarantee that the rigor criteria that it detects are appropriate for the particular study. Instead it assists authors, editors, and reviewers by drawing attention to sections of the manuscript that contain or should contain various rigor criteria and key resources.
