Alveolitis in severe SARS-CoV-2 pneumonia is driven by self-sustaining circuits between infected alveolar macrophages and T cells 2020-08-05 .txt text/plain 7453 427 44 We performed single cell RNA-Seq in 5 bronchoalveolar lavage fluid samples collected from patients with severe COVID-19 within 48 hours of intubation. b. Sankey diagram illustrating relationship between number of BAL samples from participants with COVID-19, other viral pneumonia, non-viral pneumonia (other pneumonia) and non-pneumonia controls 1) enrolled in the SCRIPT study (534 samples), 2) analyzed via flow cytometry (344 samples), 3) bulk RNA-seq on flow-sorted alveolar macrophages (243 samples) and 4) single-cell RNA-seq (6 samples). To define the immune cell profile over the course of severe SARS-CoV-2-induced pneumonia, we analyzed 116 samples from 61 patients with confirmed COVID-19 in our cohort. As our analysis of transcriptomic data from alveolar macrophages suggested that SARS-CoV-2 pneumonia is uniquely associated with the activation of pathways induced by interferons, we looked for the expression of type I interferons in our single cell dataset. ./cache/cord-304356-jyp9gjh9.txt ./txt/cord-304356-jyp9gjh9.txt
