Abstract
Irradiated C57BL/6(B6) mice, when they were injected with spleen cells of C57BL/6J-lpr/lpr(B6-lpr) mice, developed splenomegaly at 2 weeks post-transfer, but afterward displaced by GVH-like disease. At 2 weeks the enlarged spleen in the chimeric mice, designated as [B6-lpr----B6] chimera, contained about 70% of the total cell population as CD8-positive T cells. Spleen cells from [B6-lpr----B6] chimeras were unresponsive to Con A and LPS stimulation and suppressed the mitogenic response of B6, B6-lpr, and C3H spleen cells to Con A. However, they had no cytotoxic activity towards Con A blasts of B6 and B6-lpr spleen cells. The suppressor activity found in the [B6-lpr----B6] spleen cells was removed by pretreatment of them with anti-Thy-1.2 or anti-CD8(Lyt2.2) plus complement. The present experiment showed that enormous proliferation of CD8-positive suppressor T cells was induced in the [B6-lpr----B6] chimeras. These cells were probably responsible for the GVH-like lymphoid atrophy observed in these [B6-lpr----B6] chimeras.

Abstract
The lpr gene in homozygous form induces development of CD4-CD8-B220+ T cells and lymphadenopathy in MRL and C57BL/6 mice. Although the propensity for excessive production of T cells is related to an intrinsic T cell defect, a thymus is also required because neonatal thymectomy eliminates lymphadenopathy. Recent evidence suggests that excessive production and release of autoreactive T cells from the thymus of lpr/lpr mice might lead to downregulation of CD4 and CD8 as a "fail safe" tolerance mechanism that occurs during late thymic or post-thymic development. To test this hypothesis, T cell receptor (TCR) transgenic mice that produce large numbers of immature thymocytes recognizing the H-2Db and male H-Y antigens were backcrossed with C57BL/6-lpr/lpr mice and MRL-lpr/lpr mice. It was predicted that Db male lpr/lpr mice would produce large numbers of autoreactive T cells during early thymic development that would lead to an accelerated lymphoproliferative disease. In contrast, Db female lpr/lpr mice would produce large numbers of Db H-Y-reactive T cells, but might not develop lymphadenopathy because the male H-Y antigen would not be present. Unexpectedly, there was complete elimination of lymphadenopathy in both male and female TCR transgenic lpr/lpr mice. The elimination of lymphadenopathy was not due to a failure of thymic maturation since the thymus of H-2Db female lpr/lpr mice contained nearly normal numbers of mature thymocytes. Elimination of lymphadenopathy was also not due to a lack of autoreactive T cells in the peripheral lymph nodes (LN) since there was an increased syngeneic mixed lymphocyte proliferative response of LNT cells from transgenic lpr/lpr compared with +/+ mice in vitro. Hypergammaglobulinemia and autoantibody production in the transgenic lpr/lpr was present at levels comparable with or higher than control nontransgenic lpr/lpr mice, suggesting a dissociation of autoantibody production from the lymphoproliferative disease in the TCR transgenic mice. Conversely, the development of lymphadenopathy and production of CD4-CD8-B220+ T cells appear to be intimately linked, as both were completely eliminated in T cells expressing the transgenic TCR. We propose that lymphoproliferation and production of CD4-CD8-6B2+ T cells in lpr/lpr mice is related to decreased expression of the TCR, and providing the T cells with a rearranged TCR transgene overcomes this defect.

Abstract
During the last decade, transgenic animal technology has assumed an increasingly important role as a critical tool in animal biology, biomedical research, and pharmaceutical development. This technology allows virtually any fragment of DNA large enough to contain an entire gene to become integrated into the germline of the recipient animal. The newly inserted DNA will be inherited like endogenous genes, and will be expressed as RNA and protein at tissue locations and abundance depending on regulatory elements attached to the coding DNA. It is possible to clone a particular gene, change a regulatory coding sequence, and reinsert the gene to determine the effect of the change on expression and function of the gene.

Abstract
When MRL/Mp-(+)/+ (MRL/+) mice are lethally irradiated and then reconstituted with bone marrow or spleen cells from MRL/Mp-lpr/lpr (MRL/lpr) mice, they develop a graft-versus-host disease (GVHD)-like syndrome, colloquially known as "lpr-GVHD". To analyze the roles of the MRL/lpr T cells in the development of "lpr-GVHD" and autoimmune diseases, several T cell lines were established from the spleen cells of MRL/+ mice suffering from "lpr-GVHD". The surface phenotypes, specificities, and functions of a representative clone (l/+T1) of the cloned T cell lines were characterized. The l/+T1 cells showed Thy-1.2+, L3T4+ and T3+, but Lyt-2- and B220- phenotypes. Proliferative response was observed by co-culturing the cells with spleen cells from MRL/+, MRL/lpr, AKR/J, and C3H/HeN mice, but not from BALB/c or C57BL/6 mice. Furthermore, the l/+ T1 cells responded to spleen cells of B10.BR and B10.A but not B10.D2 mice. The proliferative response of l/+ T1 cells to MRL/+ spleen cells was inhibited by anti-I-Ek (but not anti-I-Ak or anti-Kk) antibodies, suggesting that the specificity of l/+T1 cell culture enhanced the proliferative response only in the presence of appropriate stimulators. Treatment of stimulator cells with J11d.2 + C (but not anti-Thy-1.2 + C or 33D1 + C) abolished the stimulatory effect, indicating that B cells are effective stimulator cells for auto-MHC class II-reactive l/+T1 cells. When MRL/+ splenic B cells were co-cultured with l/+T1 cells, both B cell proliferation and IgM production were observed. In addition, IgM-class rheumatoid factor and anti-ssDNA antibody activities were found in the supernatants of MRL/+ splenic B cells co-cultured with l/+T1 cells. These results are discussed in relation to "lpr-GVHD" and autoimmunity in MRL/lpr mice.

Abstract
Transplantation of bone marrow cells from nonobese diabetic (NOD) mice, a model for type 1 diabetes mellitus, to C3H/HeN mice, which express I-E alpha molecules and have aspartic acid at residue 57 of the I-A beta chain, induced insulitis followed by overt diabetes in the recipient C3H/HeN mice more than 40 weeks after bone marrow transplantation. When cyclosporin A, which perturbs T-cell functions, was injected intraperitoneally into [NOD----C3H/HeN] chimeric mice daily for 1 month, the chimeric mice developed insulitis and overt diabetes within 20 weeks following bone marrow transplantation. Transplantation of bone marrow cells from (NZW x BXSB)F1 mice, which develop lupus nephritis, myocardial infarction, and idiopathic thrombocytopenic purpura, into C3H/HeN or C57BL/6J mice induced in the recipient strains both lupus nephritis and idiopathic thrombocytopenic purpura more than 3 months after transplantation. Transplantation of a stem-cell-enriched population from (NZW x BXSB)F1 mice into normal mice also induced autoimmune disease in the recipients. These results indicate that both systemic autoimmune disease and organ-specific autoimmune disease originate from defects that reside within the stem cells; the thymus and environmental factors such as sex hormones appear to act only as accelerating factors.

Abstract
In the (SWR x NZB)F1 (SNF1) model of lupus nephritis, pathogenic variety of IgG anti-DNA autoantibodies are induced by certain T helper (Th) cells that are either CD4+ or CD4-CD8- (double negative; DN) in phenotype. From the spleens of eight SNF1 mice with lupus nephritis, 149 T cell lines were derived and out of these only 25 lines (approximately 17%) were capable of augmenting the production of pathogenic anti-DNA autoantibodies. Herein, we analyzed the T cell receptor (TcR) V beta genes used by 16 such pathogenic autoantibody-inducing Th cell lines. Twelve of the Th lines were CD4+ and among these five lines expressed V beta 8 (8.2 or 8.3). The V beta 8 gene family is contributed by the NZB parent to the SNF1 mice, since it is absent in the SWR parental strain. Three other CD4+ Th lines expressed V beta 4, another was V beta 2+ and one line with poor autoantibody-inducing capability expressed V beta 1. Four autoantibody-inducing Th lines from the SNF1 mice had a DN phenotype and these lines were also autoreactive, proliferating in response to syngeneic spleen cells. Among these DN Th lines, two expressed V beta 6 and one expressed V beta 8.1 TcR. Both of these are forbidden TcR directed against Mls-1a (Mlsa) autoantigens expressed by the SNF1 mice and such autoreactive T cells should have been deleted during thymic ontogeny. Thus, the DN Th cells of non-lpr SNF1 mice are different from the DN cells or MRL-lpr which lack helper activity and do not express forbidden TcR. The spleens of 6 out of 19 nephritic SNF1 animals tested also showed an expansion of forbidden autoreactive TcR+ cells that were mainly DN. Two of these animals expressed high levels of V beta 6 (anti-Mlsa) and V beta 11 (anti-I-E) TcR+ cells, three others had high levels of V beta 11+ cells alone and one animal had an expanded population of V beta 17a+ (anti-I-E) cells. The I-E-reactive TcR again should have been eliminated in the SNF1 thymus, since they express I-E molecules contributed by the NZB parent. The SWR parents of SNF1, are I-E-; moreover, they lack the V beta 11 gene but they express V beta 17a in peripheral T cells. Whereas the NZB parents are I-E+, they lack a functional V beta 17a gene and they delete mature V beta 11+ T cells.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Autoimmune-susceptible, MRL-lpr/lpr (lpr) mice develop a profound lymphadenopathy resulting from the accumulation of CD4-CD8- (double-negative, DN) cells in peripheral lymphoid organs. The source and the mechanism of this abnormal accumulation of cells is still unknown. Recently, we reported that a significant number (approximately 35%) of the CD4-CD8- cells expressed J11d, a marker expressed by immature thymocytes but not by mature functional peripheral T cells. In the present study, we investigated the phenotype, growth requirements, and functional properties of purified J11d+ and J11d- subpopulations. Using the mAb, F23.1, which recognizes a TCR determinant encoded by the V beta 8 gene family, it was observed that approximately 30% of the J11d+ and J11d- DN cells expressed this determinant. Further studies on the thymus revealed that J11d+ DN cells from lpr thymus also contained F23.1+ cells (approximately 25%), whereas, similar cells from normal MRL(-)+/+mice were all F23.1-, consistent with earlier reports in other normal strains. Further phenotypic studies revealed that the peripheral J11d+ and J11d- cells from lpr mice were similar in expressing CD3, Ly-5 (B220), and Ly-24 (Pgp-1) determinants. When stimulated with phorbol myristic acetate (PMA) and recombinant IL-2 (rIL-2), only J11d- cells but not J11d+ cells responded by proliferation. However, in the presence of calcium ionophore (A23187) and PMA, both J11d+ and J11d- subpopulations proliferated by producing and responding to endogenous IL-2 but not IL-4. The lymph node T cells from 1-month-old MRL-lpr/lpr mice responded strongly when stimulated with PMA + rIL-4 or PMA + rIL-6. In contrast both J11d+ and J11d- subpopulations failed to respond when similarly stimulated. The J11d+ but not J11d- cells demonstrated spontaneous cytotoxic activity against the NK-sensitive YAC-1 tumor targets. The J11d- cells did not exhibit cytotoxic potential in spite of culture with PMA + rIL-2. Even after repeated culture in vitro with PMA + A23187 or PMA + rIL-2, both J11d+ and J11d- subpopulations failed to express the mature phenotype bearing CD4 and/or CD8 antigens. The present study demonstrates the expansion of unique J11d+, alpha beta-TCR+, DN T cells with cytotoxic potential in lpr mice and further suggests the existence of phenotypic and functional heterogeneity among the abnormal lpr DN cells.
