Transitional dendritic cells are distinct from conventional DC2 precursors and mediate proinflammatory antiviral responses


ABSTRACT: By combining single cell transcriptomics and proteomics approaches, with lineage tracing and adoptive transfer experiments, we next demonstrate that tDC originate from a bone marrow precursor shared with plasmacytoid DCs (pDCs). Using new lineage tracing mouse models, we evaluated tDC plasticity and reveal their acquisition of Esamhi conventional DC type 2 (cDC2) features. Finally, we present tDC capacity to quickly response to stimulation and potently activate antigen-specific naïve T cells, demonstrating that these cells harbor functions of differentiated DCs. Our findings clarify tDC nature and reveal these cells as a unique lineage of DCs related developmentally to pDCs.
