Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal lung disease with limited therapeutic options. Although macrophages have been implicated in pathogenesis in murine models, their role in human disease remains unclear. Here, we present a comprehensive, unbiased single-cell transcriptomic and regulon atlas of myeloid cells from the alveolar barrier and lung tissue. We demonstrate that alveolar barrier macrophages are transcriptionally distinct from their lung tissue counterparts, exhi...
