Shaping of the TCR αβ T cell repertoire involves several distinct compartments of the thymic environment. The cortical compartment, composed largely of a reticular network of epithelial cells that present an array of peptide–MHC complexes, plays a critical role in the positive selection process.
Webb23 nov. 2024 · The thymic medulla is enriched in hematopoietic antigen-presenting cells, including DCs and B cells, which contribute to the establishment of self-tolerance in T cells ( 93–97 ). Thymic DCs are classified into CD8α + Sirpα – conventional DCs (cDC1s), CD8α – Sirpα + cDCs (cDC2s) and plasmacytoid DCs (pDCs). Webb23 nov. 2024 · Medullary thymic epithelial cells (mTECs) play a critical role in central immune tolerance by mediating negative selection of autoreactive T cells through the collective expression of the peripheral self-antigen compartment, including tissue-specific antigens (TSAs).
