Abstract
We analyzed the T-cell receptor (TCR) V beta repertoire in human immunodeficiency virus type 1 (HIV-1)-infected individuals at different stages of disease. To circumvent the effect of HLA and other loci on the expressed TCR repertoire, we compared the TCR repertoire in nine pairs of monozygotic twins who were discordant for HIV infection. A semiquantitative polymerase chain reaction (PCR) assay and flow cytometry enabled us to show distinct differences in the V beta repertoire in the HIV-positive twin compared with the HIV-negative twin. By combining PCR and cytofluorometry, these differences were restricted to a specific set of TCR V beta segments, with members of the V beta 13 family perturbed in six out of seven cases and those of the V beta 21 family perturbed in four out of seven cases studied. Most of the other V beta families remained unchanged. Our results provide direct evidence for a skewed TCR repertoire in HIV infection.

Abstract
Female AKR (H-2k, Mlsa) mice were repeatedly injected with monoclonal anti-V beta 6 prior to and during syngeneic pregnancy. The offspring were born non-viable or died within 24 h. Continued injections into the mother resulted in abortions and conception eventually ceased altogether. Antisera from hyperimmunized mothers, when injected into the neonatal offspring of untreated AKR mothers, also had a lethal effect within 4 to 10 days after injection. Some mice survived for several weeks. All injected neonates developed a graft-versus-host disease (GVHD)-like syndrome characterized by runting, presence of skin lesions and weight loss. Antiserum injected in a diluted form caused similar but less severe symptoms. FACS (fluorescence-activated cell sorter) analysis of lymphocyte profiles of these mice revealed significant increases in the L3T4+ and Lyt-2+ T lymphocyte subsets; the number of V beta 6 T cells also increased. However Histopathological findings and mechanisms of the GVHD-like syndrome in these mice are discussed.

Abstract
In mice, V beta-specific negative selection is mediated by a number of superantigens encoded by various mouse mammary tumor viruses. We have identified Mtv-3, Mtv-27, Mtv-44, Mtv-8, Mtv-9, Mtv-11, and MMTV(D2.GD), and have confirmed Mtv-1. Although specificities of superantigens correlate well with sequences of their carboxy terminal regions, Mtv-44 appears to be an exception: the product is specific for V beta 3, V beta 6, V beta 8.1, and V beta 9. It remains to be determined whether Mtv-44 produces one or two different superantigens to exhibit this specificity. V beta 5+ T-cell deletion is induced by two groups of superantigens: V beta 3-specific superantigens encoded by Mtv-1, Mtv-3, Mtv-6, Mtv-13, Mtv-27, and Mtv-44, and V beta 11-specific superantigens encoded by Mtv-8, Mtv-9, and Mtv-11. Furthermore, these V beta 3-specific superantigens are also specific for V beta 17a(cz). In contrast, V beta-specific positive selection and V alpha-specific positive and negative selection do not seem to involve non-H-2 (super)antigens, although their involvement can not be excluded. In the near future, superantigens, powerful modulators of T-cell functions, will be exploited for clinical applications.

Abstract
Tolerance to the minor lymphocyte stimulating (Mls) self-antigens has been shown to be due to the intrathymic deletion of T-cell clones bearing certain T-cell receptor (TcR) V beta regions. T cells bearing these V beta regions (V beta 6, V beta 7, V beta 8.1, V beta 9) are deleted in Mlsa-positive mice. This report demonstrates that hyperimmunization of AKR mice with anti-V beta 6 breaks tolerance to the self-antigen Mlsa and induces the development of anti-Mlsa antibodies. These antibodies had the capacity to block Mlsa-induced mixed lymphocyte responses between H-2 identical strain combinations and also between Mlsa-congeneic BALB.D2MA and parental BALB/c strains. Furthermore, when the responder lymphocytes were Mlsa-positive their response to allogeneic major or minor histocompatibility antigens was enhanced in the presence of this antiserum. This indicates that Mlsa may be present on T cells and that occupancy of this ligand leads to enhanced signal transduction.

Abstract
Immunisation with anti-TCR-V beta 6 of female AKR mice prior to and during syngeneic pregnancy resulted in neonatal lethality and eventually in abortion or foetal resorption. The sera of the hyperimmunised mothers were shown to have anti-H-2k and anti-Mlsa autoantibodies and were cytotoxic to H-2k targets in vitro and also blocked Mlsa-induced mixed lymphocyte reactions. These observations are discussed herein.

Abstract
Mice expressing the minor lymphocyte stimulation antigens, Mls-1a, -2a, or -3a, singly on the B10.BR background have been generated. Mls phenotypes correlate with the integration of mouse mammary tumor viruses (MTV) in the mouse genome. The open reading frames within the 3' long terminal repeats of the integrated MTVs 1, 3, 6, and 13 encode V beta 3-specific superantigens. Sequence data for these viral superantigens is presented, indicating that it is the COOH-terminal portion of the viral superantigen that interacts with the T cell receptor V beta element.

Abstract
It has recently become clear that the minor lymphocyte stimulatory antigens (Mls) and other endogenous ligands which lead to the partial or total deletion of T cells bearing particular V beta segments are encoded by mouse mammary tumor virus (MMTV). We review here the genetic analyses of multiple V beta 11 and V beta 3 deletion ligands and demonstrate the involvement of MMTV in all examples. Several features of Mls and the V beta 11/V beta 3 deleting ligands identify them as members of the superantigen family. Bacterial superantigens are known to bind both MHC class II and the TCR in regions distinct from conventional peptide antigens. Within the MMTV genome, the 3' LTR has been identified as encoding superantigen function. We present data demonstrating that in vitro translation identifies the major product of the open reading frame (ORF) within the 3' LTR as a type II integral membrane glycoprotein. It is proposed that the type II membrane glycoprotein interacts with MHC and TCR in a manner analogous to the bacterial superantigens and distinct from conventional peptide antigen. Several unanswered questions regarding superantigen action remain; what determines total or partial deletion? How is Mls transferred between cells? These questions are addressed in the discussion.

Abstract
We previously noted that Mlsa,c C58/J responder cells proliferated unexpectedly to H-2k-compatible Mlsa or Mlsc prototypic stimulator cells in a primary mixed lymphocyte reaction. The present investigation was performed to evaluate whether the response of C58/J T cells to these H-2- and Mls-compatible stimulator cells could functionally identify a newly-defined member of the Mls superantigen family through its allostimulatory ability. We observed that C58/J responder cells also proliferated when cultured with H-2-compatible prototypic Mls(null), Mlsb (nonstimulatory), or Mlsa,c splenic stimulator cells. The widely distributed nature of the non-MHC ligand recognized by C58/J T cells is indicated by the finding that 11 of 12 H-2k inbred mouse strains clearly expressed this specificity. A gradient of stimulatory capacity from low to high across this newly-defined non-MHC difference was detected with splenocytes from these different inbred mouse strains. The Mls(a,c) genetic composition of C58/J was confirmed by the observation that crossing C58/J with parental B10.BR (responsive to both Mlsa and Mlsc determinants) generated F1 progeny that were unresponsive to H-2k-compatible Mlsa, Mlsc, or Mls(a,c) stimulator cells. Like prototypic Mlsa and Mlsc, the non-MHC specificity recognized by C58/J responder cells, termed Mlsf, was particularly sensitive to radiation (versus mitomycin C) treatment of the stimulator cells, was greatly augmented after anti-IgD activation of splenic stimulator cells, was blocked with anti-MHC class II antibody, and was effectively presented by phenotypically normal female but not B cell-defective xid+ male CBA/N F1 stimulator cells.

Abstract
Autoreactive T lymphocytes are clonally deleted during maturation in the thymus. Deletion of T cells expressing particular receptor V beta elements is controlled by poorly defined autosomal dominant genes. A gene has now been identified by expression of transgenes in mice which causes deletion of V beta 14+ T cells. The gene lies in the open reading frame of the long terminal repeat of the mouse mammary tumour virus.

Abstract
The T-cell receptor (TCR) repertoire is selected in the thymus after rearrangement of genes encoding TCR alpha and beta chains. Selection is based on the recognition by newly emergent T cells of self-ligands associated with molecules of the major histocompatibility complex: some combinations result in positive selection, others in negative selection. Negative selection, or clonal deletion, is an important mechanism for eliminating autoreactive T cells. A group of self-ligands involved in clonal deletion was identified because they, like exogenous superantigens, were recognized by almost all T cells expressing particular TCR V beta genes. V beta 17a T cells are deleted by a tissue-specific ligand; V beta 6, V beta 7, V beta 8.1 and V beta 9 T cells are deleted by the minor lymphocyte-stimulating (Mls) determinant Mls-1a; V beta 3 T cells by Mls-2a and Mls-3a; V beta 11 T cells by ligands encoded by independently segregating genes; and V beta 5 T cells by ligands encoded by two genes. Chromosome mapping using recombinant inbred strains of mice and classic backcrosses show that Mls-1a in DBA/2 mice is encoded on chromosome 1, that one of the two ligand genes for deletion of V beta 5 T cells maps to chromosome 12 and that a ligand gene for V beta 11 deletion is linked to the CD8 locus on chromosome 6. Here we present evidence from three sets of backcross mice for concordance between V beta 11 deletion ligand genes on chromosomes 6, 12 and 14 and endogenous mouse mammary tumour virus integrant (Mtv) genomes.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In order to elucidate the biological role of minor lymphocyte stimulating (Mls) gene products, we have been investigating the fundamental immunogenetic characteristics of the Mls system. In this report, we describe the distribution of stimulatory Mls products, Mlsa and Mlsc, in a panel of laboratory inbred strains based on the response pattern of H-2-compatible naive T-cell populations as well as monospecific Mlsa- or Mlsc-reactive T-cell clones. In addition, the expression of four different T-cell receptor (Tcr) b-V segment Tcrb-V3, -V6, -V8.1, and -V9, which were recently reported to be associated with T-cell recognition of Mls gene products in these strains, was examined. The results indicate that the majority of commonly used laboratory strains including those originally typed as Mlsa are also expressing Mlsc determinants and that very few independent inbred strains are non-Mlsc. Moreover, the pattern of Tcrb-V expression in spleen as well as in thymus suggests that the association between Mls expression and clonal deletion of self Mls-reactive T cells appears to be the general rule in inbred strains. Based on these results, implications for the nondetectable Mls-like gene products in other species besides the mouse are discussed.

Abstract
T cells that express the T cell receptor V beta 5.2 domain react with the class II major histocompatibility complex (MHC) molecule I-E, and V beta 5.2+ T cells are deleted in mouse strains that express I-E glycoproteins. By examination of genetically defined recombinant inbred (RI) mouse strains, it was found that the deletion was dependent on the expression of I-E and one of a limited number of non-MHC gene products (cotolerogens). The gene encoding one of these cotolerogens maps to chromosome 12 and is linked to the endogenous provirus Mtv-9. These observations suggest that the I-E-mediated and minor lymphocyte-stimulating antigen (Mls)-mediated deletions of alpha beta T cells from the repertoire are similar; both require the expression of a class II MHC glycoprotein and a second non-MHC gene product.

Abstract
Staphylococcal enterotoxin B (SEB) has been shown in the past to be a potent T cell stimulant in mouse or man. The toxin acts as a superantigen that is, it binds to class II MHC proteins and, as such a complex, stimulates T cells bearing particular V beta s as part of their receptors. The toxin also has several pathological effects, causing, in mice, rapid weight loss, thymus atrophy, immunosuppression, and, at high doses, death. The data in this paper show that at least one of these effects, weight loss, is T cell mediated. Staphylococcal enterotoxin-mediated weight loss is MHC dependent, and is almost absent in animals expressing MHC class II molecules, which, complexed with SEB, are poor T cell stimulants. Also, mice that lack T cell function, genetically or because of cyclosporin A treatment, lose no or less weight than controls in response to SEB. Finally, animals bred such that they express few T cells bearing V beta s with which SEB can interact lose much less weight in response to the toxin than littermate controls that have higher numbers of reactive T cells. It is therefore suggested that the pathological effects of the staphylococcal, T cell-stimulating toxins in mouse and man may be partially or wholly the consequence of massive T cell stimulation.
