Medullary epithelial cells
WebCortical thymic epithelial cells (cTECs) regulate T cell lineage commitment and positive selection, while medullary (m) TECs impose central tolerance on the T cell repertoire. During thymus organogenesis, these functionally distinct sub-lineages are thought to arise from a common thymic epithelial progenitor cell (TEPC). Web1 mei 2024 · Medullary thymic epithelial cells (mTECs) act as one of the major stromal components in the thymus for selection and maturation of both conventional T cells and non-conventional T cells. Extensive efforts have been spent to understand how mTEC development and function are regulated. Although RelB has been well accepted to be a …
