• Interferon regulatory factor-8 (IRF8) has been proposed to be essential for development of monocytes, plasmacytoid dendritic cells (pDCs) and type 1 conventional dendritic cells (cDC1s) and remains highly expressed in differentiated DCs. Transcription factors that are required to maintain the identity of terminally differentiated cells are designated “terminal selectors.” Using BM chimeras, conditional Irf8fl/fl mice and various promotors to target Cre recombinase to different stages of monocyte and DC development, we have identified IRF8 as a terminal selector of the cDC1 lineage controlling survival. In monocytes, IRF8 was necessary during early but not late development. Complete or late deletion of IRF8 had no effect on pDC development or survival but altered their phenotype and gene-expression profile leading to increased T cell stimulatory function but decreased type 1 interferon production. Thus, IRF8 differentially controls the survival and function of terminally differentiated monocytes, cDC1s, and pDCs. [Display omitted] •IRF8 is dispensable for survival of terminally differentiated monocytes•IRF8 is a terminal selector of the cDC1 lineage•IRF8 is not intrinsically required for pDC development•IRF8 controls several functional modules in differentiated pDCs IRF8 has been proposed to be essential for the development of monocytes, pDCs, and cDC1s. By using several conditional Irf8-deficient mice, Sichien et al. demonstrate that IRF8 is dispensable for monocyte development after the cMoP stage. Moreover, they show that IRF8 is required for the survival and function of cDC1s and pDCs, respectively.
