Abstract

We investigated SARS-CoV-2 potential tropism by surveying expression of viral entry-associated genes in single-cell RNA-sequencing data from multiple tissues from healthy human donors. We co-detected these transcripts in specific respiratory, corneal and intestinal epithelial cells, potentially explaining the high efficiency of SARS-CoV-2 transmission. These genes are co-expressed in nasal epithelial cells with genes involved in innate immunity, highlighting the cells’ potential role in initial viral infection, spread and clearance. The study offers a useful resource for further lines of inquiry with valuable clinical samples from COVID-19 patients and we provide our data in a comprehensive, open and user-friendly fashion at www.covid19cellatlas.org . An analysis of single-cell transcriptomics datasets from different tissues shows that ACE2 and TMPRSS2 are co-expressed in respiratory, corneal and intestinal epithelial cell populations, and that respiratory expression of ACE2 is associated with genes involved in innate immunity.

  • ACE2 and TMPRSS2 are highly co-expressed in nasal epithelial cells, particularly in two types of goblet cells and a subset of ciliated cells, with the highest expression among cells in the respiratory tree.

    “Probably most important for the high efficacy of SARS-CoV-2 transmission is the high co-expression of ACE2 and TMPRSS2 in nasal epithelial cells, particularly in two types of goblet cells and a subset of ciliated cells, showing the highest expression among all cells in the respiratory tree (Figure 2 A).”

  • Nasal epithelial cells co-express genes involved in early antiviral immune responses, indicating that these specialized cells may play an important role in initial viral infection, spread, and potentially clearance.

    “An interesting observation of this study was the high co-expression of genes involved in early steps of antiviral immune responses in these epithelial cells, which indicated the potential for these specialized nasal cells to play an important role in the initial viral infection, spread, but potentially also, clearance.”

  • TMPRSS2 is more widely expressed than ACE2, and cells with simultaneous expression occur in the respiratory tree, cornea, esophagus, ileum, colon, gallbladder, and common bile duct, with no evidence for simultaneous expression in immune cells.

    “TMPRSS2 is more widely expressed than ACE2, and cells with simultaneous expression were identified in the respiratory tree, the cornea, esophagus, ileum, colon, gallbladder, and common bile duct (Sungnak et al., 2020), yet there was no evidence for simultaneous expression in immune cells.”

    From COVID-19 and the human innate immune system (2021) · cites this paper as Sungnak et al., 2020

  • Cells from the human upper airway, including nasal respiratory epithelium goblet and ciliated cells, express high levels of ACE2 and TMPRSS2, suggesting these respiratory epithelium cell types may serve as a viral reservoir during CoV-2 infection.

    “It has recently been demonstrated through single cell RNA sequencing analysis (referred to herein as scSeq) that cells from the human upper airway — including nasal RE goblet and ciliated cells —express high levels of ACE2 and TMPRSS2, suggesting that these RE cell types may serve as a viral reservoir during CoV-2 infection (39, 40).”
  • In human scSeq data, ACE2 transcripts were detected in only a subset of olfactory epithelium cells, and this low level of observed expression matches or exceeds that observed in respiratory cell types that are infected by CoV-2 in COVID-19 patients.

    “Although scSeq revealed ACE2 transcripts in only a subset of OE cells, this low level of observed expression matches or exceeds that observed in respiratory cells types that are infected by CoV-2 in COVID-19 patients (39) (Fig. 3).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
