Title: The landscape of lung bronchoalveolar immune cells in COVID-19 revealed by single-cell RNA sequencing Document date: 2020_2_26
ID: 8l1vfsbc_6
Snippet: Here, we applied the emerging single-cell RNA sequence (scRNA-seq) and single-cell TCR-seq to comprehensively characterize the lung bronchoalveolar lavage fluid (BALF) cells from 6 of COVID-19 patients, including 3 severe and 3 mild cases. Our study depicts a high-resolution transcriptome atlas of lung resident immune subsets in response to SARS-CoV-2 infections. It reveals that compared to the lung immune microenvironment of mild symptom patient.....
Document: Here, we applied the emerging single-cell RNA sequence (scRNA-seq) and single-cell TCR-seq to comprehensively characterize the lung bronchoalveolar lavage fluid (BALF) cells from 6 of COVID-19 patients, including 3 severe and 3 mild cases. Our study depicts a high-resolution transcriptome atlas of lung resident immune subsets in response to SARS-CoV-2 infections. It reveals that compared to the lung immune microenvironment of mild symptom patients, monocyte-derived FCN1 + macrophages replacing the FABP4 + alveolar macrophages predominate macrophage lineage compostions in the severely damaged lung, which are highly inflammatory and potent chemokine producers. Furthermore, the lung resident highly expanded clonal CD8 + T All rights reserved.
