Most current models of T cell development include a positive selection step in the thymus that occurs when T cells interact with thymic epithelium and a negative selection step after encounters with bone marrow-derived cells. We show here that developing T cells are tolerized when they recognize antigens expressed by thymic epithelium, that the tolerance is tissue specific, and that it can occur by deletion of the reactive T cells.
目前大多数T细胞发育模型包括胸腺中的阳性选择步骤,该步骤发生在T细胞与胸腺上皮相互作用时,以及在与骨髓来源的细胞接触后的阴性选择步骤。我们在此表明,发育中的T细胞在识别胸腺上皮表达的抗原时会产生耐受性,这种耐受性具有组织特异性,并且可以通过反应性T细胞的缺失而发生。
