The contributions of IRF3/7 and the type I interferons IFNα/β to the innate host defense have been extensively investigated, however, their role in thymic development is less clear. Here we show that mice lacking the type I interferon receptor IFNAR or the downstream transcription factor STAT1 harbor a significant reduction in self-antigen presenting, autoimmune-regulator AIRE+ medullary thymic epithelial cells (mTEC). Constitutive IFNAR signaling occurs in the thymic medulla in the absence of infection or inflammation. RANKL stimulation results in IFNβ-upregulation, which in turn inhibits RANK signaling and facilitates AIRE expression in mTECs. Finally, we find that IRF7 is required for thymic IFNβ–induction, maintenance of thymic architecture and mTEC differentiation. We conclude that spatially and temporally coordinated crosstalks between the RANKL/RANK and IRF7/IFNβ/IFNAR/STAT1 pathways are essential for differentiation of AIRE+ mTECs.
