Research Abstract |
T lymphocytes are the cells that play an essential role in distinguishing non-self from self. T lymphocytes acquire this ability through shaping a repertoire of recognition specificity during the development in the thymus. However, how T lymphocytes are generated and selected in the thymus is still not well understood. This study identified (1) chemokines that are produced by thymic medullary epithelial cells and are essential for establishment of self-tolerance, (2) cytokines that are essential for the growth and development of thymic medullary epithelial cells, (3) proteasomes that are expressed in thymic cortical epithelial cells and are essential for positive selection of immunocompetent CD8 T lymphocytes. In addition, (4) we revealed that Aire regulates the development of thymic medullary epithelial cells, and (5) we begun the analysis how medullary and cortical thymic epithelial cells are generated from common epithelial progenitor cells.
