The T-cell receptor, which recognizes antigen plus a product of the major histocompatibility complex, has been postulated to drive T-cell maturation in the thymus by engaging major histocompatibility complex proteins expressed on thymic stromal cells. We tested this idea by injecting neonatal animals with an anti-receptor antibody, KJ16, that binds to about 20% of T cells and is capable of blocking receptor function. In the presence of this antibody, mature T cells bearing the KJ16 epitope failed to develop. On the other hand, although the antibody could be shown to bind to receptors on cortical thymocytes, it did not prevent the rapid expansion or survival of the bulk of the KJ16+ cells in this population. These results are consistent with the hypothesis that most cortical thymocytes arise by a receptor-independent mechanism and that only a small proportion of these cells mature by a process dependent on receptor-major histocompatibility complex interactions.
