Abstract
The autoimmune regulator (Aire), mediates central tolerance of peripheral self. Its activity in thymic epithelial cells (TECs) directs the ectopic expression of thousands of tissue-restricted antigens (TRAs), causing the deletion of autoreactive thymocytes. The molecular mechanisms orchestrating the breadth of transcriptional regulation byAire remain unknown. One prominent model capable of explaining both the uniquely high number ofAire-dependent targets and their specificity posits that tissue-specific transcription factors induced byAire directly activate their canonical targets, exponentially adding to the total number ofAire-dependentTRAs. To test this "HierarchicalTranscription" model, ..
