The sequence of events leading to a diverse and competent alpha beta T-cell repertoire has been known in outline form for some time. Details continue to be sketched in, however, and some of these suggest previously unsuspected influences on repertoire content.

✦ Synopsis
The selection of developing and mature alpha beta T cells, by intrathymic and extra-thymic ligands expressed on cells of hemopoietic and other origins, has been studied in a variety of systems. These experiments have increased our knowledge of the selection of alpha beta T cells in the thymus, in the presence or absence of specific peptides bound to MHC, and also made clear that additional selective mechanisms exist outside the thymus that can be exploited to silence mature T cells.

The past year has been marked by the application of new technologies to study thymocyte development. These studies have shown that positive selection affects a surprisingly large proportion of thymocytes, and now are beginning to investigate the affinities/avidities of the reactions involved. The le
## Abstract In conventional mice, the T cell receptor (TCR)αβ^+^ CD8αα^+^ and CD8αβ^+^ subsets of the intestinal intraepithelial lymphocytes (IEL) constitute two subpopulations. Each comprise a few hundred clones expressing apparently random receptor repertoires which are different in individual ge
