Figure Lengend Snippet: Schematic conceptualization of this study. IR activated the NF-κB signaling pathway to promote activation and maturation of DCs, amplifying inflammatory signals through the release of pro-inflammatory cytokines. The mDCs triggered oxidative stress of BMSCs, showing increased intracellular ROS levels, inhibited osteogenic differentiation, and enhanced adipogenic differentiation, which accelerated the progression of radiation-induced jaw injury. VitD3-induced tolDCs exhibited IR resistance and anti-inflammatory properties, possessing the therapeutic potential to accelerate bone regeneration in irradiated jaw defects through local administration. (IR: ionizing radiation; mDC: mature dendritic cell; tolDC: tolerogenic dendritic cell; BMSC: bone marrow mesenchymal stem cell; ROS: reactive oxygen species; vitamin D3: vitD3)
