TL;DR: The data suggest that SARS-CoV-2 could exploit species-specific interferon-driven upregulation of ACE2, a tissue-protective mediator during lung injury, to enhance infection.

TL;DR: The results confirmed the basic outlines of the classical model of epithelial cell-type diversity in the distal lung and led to the discovery of many previously unknown cell- type markers, including transcriptional regulators that discriminate between the different populations.

TL;DR: These studies define major characteristics of the transcriptional programs that underlie the life cycle, compare development in males and females, and show that large-scale gene expression data collected from whole animals can be used to identify genes expressed in particular tissues and organs or genes involved in specific biological and biochemical processes.

TL;DR: Droplet- and plate-based single cell RNA sequencing applied to ~75,000 human cells across all lung tissue compartments and circulating blood, combined with a multi-pronged cell annotation approach, have allowed them to define the gene expression profiles and anatomical locations of 58 cell populations in the human lung.

TL;DR: There is a switch after birth, when AT2 cells function as stem cells that contribute to alveolar renewal, repair and cancer, and it is proposed that local signals regulate AT2 stem-cell activity.
