Abstract excerpt
Promiscuous expression of a plethora of tissue-restricted antigens (TRAs) in medullary thymic epithelial cells (mTECs) is essential for central tolerance. This promiscuous gene expression (pGE) is characterized by inclusion of a broad range of TRAs and by its mosaic expression patterns, i.e. each antigen is only expressed in 1-3% of mTECs. It is currently unclear to which extent random and/or deterministic...
