Aire Deficiency Disrupts Thymic Architecture but Preserves TCRVβ Repertoire Diversity While Altering Thymic Output.
The autoimmune regulator (Aire) gene is essential for the establishment of central tolerance by promoting the ectopic expression of tissue-restricted antigens in medullary thymic epithelial cells (mTECs). Although Aire deficiency impairs negative selection, its impact on thymic architecture, output, and early T cell de...
