In the thymus, low-affinity T cell antigen receptor (TCR) engagement facilitates
positive selection of a useful T cell repertoire. Here we report that TCR
responsiveness of mature CD8(+) T cells is fine tuned by their affinity for
positively selecting peptides in the thymus and that optimal TCR responsiveness
requires positive selection on major histocompatibility complex class
I-associated peptides produced by the thymoproteasome, which is specifically
expressed in the thymic cortical epithelium. Thymoproteasome-independent positive
selection of monoclonal CD8(+) T cells results in aberrant TCR responsiveness,
homeostatic maintenance and immune responses to infection. These results
demonstrate a novel aspect of positive selection, in which TCR affinity for
positively selecting peptides produced by thymic epithelium determines the
subsequent antigen responsiveness of mature CD8(+) T cells in the periphery.
