Little to no expression of angiotensin‐converting enzyme‐2 on most human peripheral blood immune cells but highly expressed on tissue macrophages
Open accessAbstract
Angiotensin‐converting enzyme‐2 (ACE2) has been recognized as the binding receptor for the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). Flow cytometry demonstrated that there was little to no expression of ACE2 on most of the human peripheral blood‐derived immune cells including CD4+ T, CD8+ T, activated CD4+/CD8+ T, Tregs, Th17, NKT, B, NK cells, monocytes, dendritic cells, and granulocytes. There was no ACE2 expression on platelets and very low level of ACE2 protein expression on the surface of human primary pulmonary alveolar epithelial cells. The ACE2 expression was markedly upregulated on the activated type 1 macrophages (M1). Immunohistochemistry demonstrated high expressions of ACE2 on human tissue macrophages, such as alveolar macrophages, Kupffer cells within livers, and microglial cells in brain at steady state. The data suggest that alveolar macrophages, as the frontline immune cells, may be directly targeted by the SARS‐CoV‐2 infection and therefore need to be considered for the prevention and treatment of COVID‐19.

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.
