Analysis of genetic variation within and among samples of naturally produced Atlantic salmon (n = 372) from 7 Maine (U.S.A.) and one Canadian river were conducted based on 54 allozyme loci. Eight of the 54 loci proved polymorphic, and estimated heter

T cell activation requires at least two signals transduced by the Ag-specific TCR plus a costimulatory receptor. The CD28 costimulatory molecule has been shown to promote T cell proliferation and cytokine production. CTLA-4, a cell surface molecule h

The lpr mutation, a disruption of the fas gene, induces spontaneous autoimmunity characterized by high titers of autoantibodies, lymphadenopathy, autoreactive T cells, and early mortality. The mechanism of autoimmunity, however, remains unknown. The

TCR (beta-chain) transgenic mice were tolerized with the superantigen staphylococcal enterotoxin B (SEB). Three to 28 days after tolerization with SEB, flow cytometry of peripheral T cells showed the persistence of SEB-unresponsive T cells that did n

The T cell response to complex protein Ag typically focuses on a few, and frequently a single, immunodominant epitope. Several groups have proposed that the mechanism of immunodominance is determined by the steps of Ag processing and presentation inc

In a murine model of T cell-mediated autoimmune disease, experimental autoimmune encephalitis (EAE), 80% of all encephalitogenic T cell clones in H-2u mice use the V beta 8.2 TCR element. To induce EAE in susceptible strains of mice either heat-kille

The degree to which processed self-peptides contribute to the stimulation of autoreactive T cells has not been determined. In this study we have analyzed a panel of autoreactive T cell hybridomas from normal C57BL/26 mice produced by fusing periphera

Despite the tremendous plasticity of the TCR repertoire, T cells recognize a limited number of antigenic sites (frequently a single site, or immunodominant epitope) on a complex protein Ag. Current models suggest that the immunodominant epitope of a

We have used an approach of linking previously characterized T cell epitopes into immunologically complex synthetic peptides in order to investigate the mechanism of immunodominance. Our results show that first, cI12-26 is highly dominant following i

Stem cells from a lpr/lpr mouse do not cause the lpr syndrome characteristic of unmanipulated MRL/lpr mice when injected into nonautoimmune neonatal mice. Instead, these neonatal chimeras gradually become markedly lymphopenic. As adults, only limited
