It has previously been demonstrated that mature mouse T cells live for many weeks in vivo. In contrast, explanted lymph node or splenic T cells undergo spontaneous death within days, suggesting that survival factors supplied in vivo are not present i

The Staphylococcus aureus enterotoxins are known to be potent T cell activators, stimulating cell proliferation and lymphokine production. Two additional S. aureus proteins, exfoliating toxin and toxic shock syndrome toxin, share these properties. Re

A 17-amino acid tryptic peptide of chicken ovalbumin, designated P323-339, that substituted for processed antigen when presented by glutaraldehyde prefixed accessory cells to specific I-restricted T hybridomas was characterized. The peptide antigen c

KJ23a+ T cell clones, which bear the determinant encoded by the V beta 17a T cell receptor gene segment, frequently recognize IE molecules of various murine H-2 haplotypes. In the presence of IE molecules, thymic maturation of KJ23a+ clones is infreq

Research on the specificities, functions, and maturation of T cells would be greatly aided by a collection of monoclonal antibodies which distinguishes different types of TCR. With this end in mind hamsters were immunized and tested for production of

The TCR alpha/beta variable element V beta 17a is expressed in all strains of mice carrying the V beta a complex in which about half of the V beta elements have been lost due to a large deletion. The mAb KJ23a detects V beta 17a containing alpha/beta

We determined if self-reactive T cells are able to escape thymic tolerance in autoimmune New Zealand mice. T cells utilizing V beta 17a and V beta 11 encoded receptors have been shown to be clonally eliminated in nonautoimmune mice expressing I-E bec

Ligand binding to alpha beta TCR has different consequences in thymocytes at different developmental stages, causing alternatively positive selection, clonal deletion, or activation. These various functional consequences may be due to changes in the
