The landscape of lung bronchoalveolar immune cells in COVID-19 revealed by single-cell RNA sequencing 2020-02-26 .txt text/plain 4710 311 55 Here, we comprehensively characterized the lung immune microenvironment with the bronchoalveolar lavage fluid (BALF) from 3 severe and 3 mild COVID-19 patients and 8 previously reported healthy lung controls through single-cell RNA sequence (scRNA-seq) combined with TCR-seq. To characterize the immune microenvironment of the SARS-CoV-2-infected lung, we performed scRNA-seq analysis of single cells in the lung BALF (37, 820 cells) using the 10X Genomics platform, from 3 of recovered mild cases and 3 of severe cases ( Figure 1A , Table 1 ). Our data indicated that the monocytes are recruited from circulation (FCN1 + ) to the lung to fuel the inflammation during severe diseases, and some monocytes may further go through the differentiation process into the SPP1 + populations and eventually the FABP4 + AMs. robust and early T cell response played crucial roles in viral clearance during acute respiratory infections [14] . ./cache/cord-335446-8l1vfsbc.txt ./txt/cord-335446-8l1vfsbc.txt
