Single-cell RNA-sequencing data. Ziegler et al. analyzed human scRNA-seq data to uncover potential targets of SARS-CoV-2 amongst tissue-resident cell subsets. They discovered ACE2 and TMPRSS2 co-expressing cells in nasal goblet secretory cells, lung type II pneumocytes, and ileal absorptive enterocytes . Consequently, we screened the 1,588 nodes previously obtained from the PPi network and revealed all genes whose RNAs were significantly overexpressed (Z score > 2) in nasal goblet secretory cells , lung type II pneumocytes, and ileal absorptive enterocytes according to the Alexandria Project (). Lastly, it is important to clarify that the scRNA-seq analyses were done in cells non exposed to the novel coronavirus.
