Abstract

Despite the unprecedented effort of the scientific community, the novel SARS-CoV-2 virus has infected more than 46 million people worldwide, killing over one million two hundred thousand. Understanding the mechanisms by which some individuals are more susceptible to SARS-CoV-2 infection and why a subgroup of them are prone to experience severe pneumonia, and death should lead to a better approach and more effective treatments for COVID-19. Here, we focus our attention on ACE2, a primary receptor of SARS-CoV-2. We will discuss its biology, tissue expression, and post-translational regulation that determine its potential to be employed by SARS-CoV-2 for cell entry. Particular attention will be given to how the ACE2 soluble form can have a great impact on disease progression and thus be used in a potential therapeutic strategy. Furthermore, we will discuss repercussions that SARS-CoV-2/ACE2 binding has on the renin-angiotensin system and beyond. Indeed, although mostly neglected, ACE2 can also act on [des-Arg 937]-bradykinin of the kinin-kallikrein system regulating coagulation and inflammation. Thorough comprehension of the role that ACE2 plays in different pathways will be the key to assess the impact that SARS-CoV-2/ACE2 binding has on organismal physiology and will help us to find better therapies and diagnostic tools.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • K18-hACE2 transgenic mice have a human ACE2 receptor which is the major cell entry receptor for SARS-CoV-2.

    “These transgenic mice have a human ACE2 receptor which is the major cell entry receptor for SARS-CoV-216,17.”

    From Efficacy of an unmodified bivalent mRNA vaccine against SARS-CoV-2 variants in female small animal models (2023) · cites this paper as [16]

    The Introduction states that ACE2 is used by SARS-CoV-2 to enter human cells, supporting the receptor portion of the claim. Our copy does not establish that K18-hACE2 transgenic mice carry human ACE2; searches for that mouse model and for transgenic mice expressing human ACE2 did not find it. (LLM, conf=0.88)

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.
