Single cell RNA sequencing identifies unique inflammatory airspace macrophage subsets

In this study, we characterize transciprtional phenotypes of airway macrophagages (AMs) throughout homeostatsis, inflammation, and repair at single cell granularity. We confirm that cell origin is the major determinant of AM programing and describe two previously uncharacterized, transcriptionally distinct subdivisions of AMs based on proliferative capacity and inflammatory programing. Overall design: We stimulated mice with LPS and then sampled FACs sorted airway macrophage cells using BAL at Days 0, 3, and 6 and sequenced 1,134 cells from these three groups using RNA-seq
