| Abstract |
ACE2 and accessory proteases (TMPRSS2, CTSL) are needed for SARS-CoV-2 cellular entry, and their expression may shed light on viral tropism and impact across the body. We assess the cell type-specific expression of ACE2, TMPRSS2, and CTSL across 107 single-cell RNA-Seq studies from different tissues. ACE2, TMPRSS2, and CTSL are co-expressed in specific subsets of respiratory epithelial cells in the nasal passages, airways, and alveoli, and in cells from other organs associated with COVID-19 transmission or pathology. We performed a meta-analysis of 31 lung scRNA-seq studies with 1,320,896 cells from 377 nasal, airway, and lung parenchyma samples from 228 individuals. This revealed cell type specific associations of age, sex, and smoking with expression levels of ACE2, TMPRSS2, and CTSL. Expression of entry factors increased with age and in males, including in airway secretory cells and alveolar AT2 cells.
Expression programs shared by ACE2+TMPRSS2+ cells in nasal, lung and gut tissues included. |
