Single-cell RNA expression profiling of ACE2, the receptor of SARS-CoV-2
Abstract: A novel coronavirus (2019-nCov) was identified in Wuhan, Hubei Province, China in December of 2019. This new coronavirus has resulted in thousands of cases of lethal disease in China, with additional patients being identified in a rapidly growing number internationally. 2019-nCov was reported to share the same receptor, Angiotensin-converting enzyme 2 (ACE2), with SARS-Cov.Here based on the public database and the state-of-the-art single-cell RNA-

“…Alveolar epithelial type 2 (AT2), ciliated and club cells emerged as the cells with the highest expression of both receptors (Fig 1A; Fig S1A). These observations are consistent with published studies demonstrating that ACE2 is indeed expressed highest in AT2 and ciliated cells (Jia et al, 2005;Mulay et al, 2020;Zhao et al, 2020). In a cohort of deceased COVID-19 patients, we observed by H&E ( Fig S1B) that gas-exchanging flattened AT1 pneumocytes are virtually replaced by cuboidal cells that were subsequently confirmed to be AT2-like cells via immunofluorescent staining with the AT2-specific marker, surfactant protein-C (SFTPC; Fig 1B upper panel; Fig S1C; top).…”

“…The ACE2 expressed cells were significantly enriched in CRC samples compared with CRA and NC samples (5.15% vs 2.94% and 1.75%, p<0.05) (Fig.2 B, C). In consistent with previous studies( 9, 10 ), we also observed that ACE2 cell were mainly expressed in epithelial cells which highly express EPCAM(Fig.2D).…”

“…We found that the majority of ACE2-expressing cells in normal human lung tissues were AT2 cells ( SFTPC -positive) (Fig. 1A and 1C), which is consistent with a previous study 7 . Unexpectedly, ACE2 was mainly expressed in arterial vascular cells, but rarely in AT2 in fibrotic lung tissues (Fig.…”
