Abstract
Genetic susceptibility to type 1 diabetes is associated with homozygous expression of major histocompatibility complex class II alleles that carry specific beta chain polymorphisms. Why heterozygous expression of these major histocompatibility complex class II alleles does not confer a similar predisposition is unresolved. Using a nonobese diabetic mouse model, here we show that heterozygous expression of the type 1 diabetes-protective allele I-Ag7 β56P/57D induces negative selection to the I-Ag7-restricted T cell repertoire, including beta-islet-specific CD4+ T cells. Surprisingly, negative selection occurs despite I-Ag7 β56P/57D having a reduced ability to present beta-islet antigens to CD4+ T cells. Peripheral manifestations of non-cognate negative selection include a near complete loss of beta-islet-specific CXCR6+ CD4+ T cells, an inability to cross-prime islet-specific glucose-6-phosphatase catalytic subunit-related protein and insulin-specific CD8+ T cells and disease arrest at the insulitis stage. These data reveal that negative selection on non-cognate self-antigens in the thymus can promote T cell tolerance and protection from autoimmunity.

Abstract
Type 1 diabetes (T1D) has a strong genetic component. The insulin dependent diabetes (Idd)22 locus was identified in crosses of T1D-susceptible NOD mice with the strongly T1D-resistant ALR strain. The NODcALR-(D8Mit293-D8Mit137)/Mx (NOD-Idd22) recombinant congenic mouse strain was generated in which NOD mice carry the full Idd22 confidence interval. NOD-Idd22 mice exhibit almost complete protection from spontaneous T1D and a significant reduction in insulitis. Our goal was to unravel the mode of Idd22-based protection using in vivo and in vitro models. We determined that Idd22 did not impact immune cell diabetogenicity or β cell resistance to cytotoxicity in vitro. However, NOD-Idd22 mice were highly protected against adoptive transfer of T1D. Transferred CTLs trafficked to the pancreatic lymph node and proliferated to the same extent in NOD and NOD-Idd22 mice, yet the accumulation of pathogenic CTLs in the islets was significantly reduced in NOD-Idd22 mice, correlating with disease resistance. Pancreatic endothelial cells from NOD-Idd22 animals expressed lower levels of adhesion molecules, even in response to inflammatory stimuli. Lower adhesion molecule expression resulted in weaker adherence of T cells to NOD-Idd22 endothelium compared with NOD-derived endothelium. Taken together, these results provide evidence that Idd22 regulates the ability of β cell-autoreactive T cells to traffic into the pancreatic islets and may represent a new target for pharmaceutical intervention to potentially prevent T1D.

Abstract
The field of immunometabolism has come a long way in the past decade, leading to the emergence of a new role for white adipose tissue (WAT) that is now recognized to stand at the junction of immune and metabolic regulations. Interestingly, a crucial role of the abundant and heterogeneous immune population present in WAT has been proposed in the induction and development of metabolic diseases. Although a large body of data focused on mature immune cells, only few scattered studies are dedicated to leukocyte production, and the activity of hematopoietic stem cells (HSC) in these pathological states. Considering that blood cell production and the differentiation of HSCs and their progeny is orchestrated, in part, by complex interacting signals emanating from their microenvironment, it thus seems worth to better understand the relationships between metabolism and HSC. This review discusses the alterations of hematopoietic process described in metabolic diseases and focused on the emerging data concerning HSC present in WAT.

Abstract
Although once widely anticipated to unlock how human type 1 diabetes (T1D) develops, extensive study of the nonobese diabetic (NOD) mouse has failed to yield effective treatments for patients with the disease. This has led many to question the usefulness of this animal model. While criticism about the differences between NOD and human T1D is legitimate, in many cases disease in both species results from perturbations modulated by the same genes or different genes that function within the same biological pathways. Like in humans, unusual polymorphisms within an MHC class II molecule contributes the most T1D risk in NOD mice. This insight supports the validity of this model and suggests the NOD has been improperly utilized to study how to cure or prevent disease in patients. Indeed, clinical trials are far from administering T1D therapeutics to humans at the same concentration ranges and pathological states that inhibit disease in NOD mice. Until these obstacles are overcome it is premature to label the NOD mouse a poor surrogate to test agents that cure or prevent T1D. An additional criticism of the NOD mouse is the past difficulty in identifying genes underlying T1D using conventional mapping studies. However, most of the few diabetogenic alleles identified to date appear relevant to the human disorder. This suggests that rather than abandoning genetic studies in NOD mice, future efforts should focus on improving the efficiency with which diabetes susceptibility genes are detected. The current review highlights why the NOD mouse remains a relevant and valuable tool to understand the genes and their interactions that promote autoimmune diabetes and therapeutics that inhibit this disease. It also describes a new range of technologies that will likely transform how the NOD mouse is used to uncover the genetic causes of T1D for years to come.

Abstract
In the past years, in the field of β-cell replacement for diabetes therapy, the easy availability of bone marrow (BM) and the widely consolidated clinical experience in the field of hematology have contributed to the development of strategy to achieve donor-specific transplantation tolerance. Recently, the potential role of BM in diabetes therapy has been reassessed from a different point of view. Diverse groups investigated the contribution of BM cells to β-cell replacement as direct differentiation into insulin-producing cells. More importantly, while direct differentiation is highly unlikely, a wide array of experimental evidences indicates that cells of BM origin are capable of facilitating the survival or the endogenous regeneration of β-cells through an as yet well-defined regeneration process. These new experimental in vitro and in vivo data will expand in the near future the clinical trials involving BM or BM-derived cells to cure both type 1 and type 2 diabetes in humans. In this review we recapitulate the history of use of BM in diabetes therapy and we provide clinically relevant actual information about the participation of BM and BM-derived stem cells in islet cell regeneration processes. Furthermore, new aspects such as employing BM as "feeder tissue" for pancreatic islets and new clinical use of BM in diabetes therapy are discussed.

Abstract
Using animal models for autoimmune diseases, we have previously shown that allogeneic bone marrow transplantation (allo BMT) can be used to treat autoimmune diseases. Using cynomolgus monkeys, we have recently developed new BMT methods for the treatment of autoimmune diseases. The methods include the perfusion method (PM) for the collection of bone marrow cells (BMCs), and intra-bone marrow (IBM)-BMT for the direct injection of collected whole BMCs into the bone marrow cavity. The PM, in comparison with the conventional aspiration method, can minimize the contamination of BMCs with T cells from the peripheral blood. Therefore, without removing T cells, no graft-versus-host disease (GvHD) develops in the case of the PM. Since BMCs collected by the PM contain not only hemopoietic stem cells (HSCs) but also mesenchymal stem cells (MSCs), the injection of both cells directly into the bone marrow cavity (IBM-BMT) facilitates the engraftment of donor hemopoietic cells. In organ allografts with IBM-BMT, no graft failure occurs even if the radiation dose is reduced. In addition, IBM-BMT is applicable to regeneration therapy and various age-associated diseases such as osteoporosis, since it can efficiently recruit donor-derived normal MSCs. We have also found that IBM-BMT in conjunction with donor lymphocyte infusion can prevent GvHD, but suppress tumor growth. We believe that this strategy heralds a revolution in the field of transplantation (BMT and organ allografts) and regeneration therapy.

Abstract
In children, autoimmune diseases and their therapies cause significant morbidity, especially in those with severe or refractory disease. The constant development of new immunosuppressants and targeted biological therapies leads to a unique 'moving target' with regard to the gold standard of treatment for these patients. However, incidental findings of cure after hematopoietic stem cell transplant (HSCT) in patients with concomitant benign or malignant hematologic disorders and autoimmune disease raise the question of whether HSCT can be used as upfront therapy for patients with severe autoimmune diseases. Animal data have been helpful in investigating both the efficacy of this modality and the mechanisms underlying cure. The potential for a therapeutic 'graft vs autoimmunity' (GVA) effect with an allogeneic approach highlights the already acknowledged need for clinical trials of allogeneic vs autologous transplant in these diseases where an autologous transplant would be the 'intuitive' albeit potentially erroneous choice. We critically review the data generated in the field thus far, and emphasize the need for an organized, interdisciplinary approach to conduct prospective clinical trials to answer these and other questions and advance the field.

Abstract
Although type 1 diabetes cannot be prevented or reversed, replacement of insulin production by transplantation of the pancreas or pancreatic islets represents a definitive solution. At present, transplantation can restore euglycemia, but this restoration is short-lived, requires islets from multiple donors, and necessitates lifelong immunosuppression. An emerging paradigm in transplantation and autoimmunity indicates that systemic inflammation contributes to tissue injury while disrupting immune tolerance. We identify multiple barriers to successful islet transplantation, each of which either contributes to the inflammatory state or is augmented by it. To optimize islet transplantation for diabetes reversal, we suggest that targeting these interacting barriers and the accompanying inflammation may represent an improved approach to achieve successful clinical islet transplantation by enhancing islet survival, regeneration or neogenesis potential, and tolerance induction. Overall, we consider the proinflammatory effects of important technical, immunological, and metabolic barriers including: 1) islet isolation and transplantation, including selection of implantation site; 2) recurrent autoimmunity, alloimmune rejection, and unique features of the autoimmune-prone immune system; and 3) the deranged metabolism of the islet transplant recipient. Consideration of these themes reveals that each is interrelated to and exacerbated by the other and that this connection is mediated by a systemic inflammatory state. This inflammatory state may form the central barrier to successful islet transplantation. Overall, there remains substantial promise in islet transplantation with several avenues of ongoing promising research. This review focuses on interactions between the technical, immunological, and metabolic barriers that must be overcome to optimize the success of this important therapeutic approach.

Abstract
Bone marrow (BM) transplantation has been used to study the cellular basis of genetic control of autoimmune diseases, but conclusions remain elusive due to the contradictory findings in different animal models. In the current study, we found that BM cells from myocarditis-susceptible A.SW mice can render irradiated, myocarditis-resistant B10.S recipient mice susceptible to myosin-induced myocarditis, indicating that hematopoietic cells express the genetic differences controlling susceptibility to autoimmune myocarditis. We then sought to differentiate the role of lymphoid vs nonlymphoid components of BM in the pathogenesis of myocarditis by comparing mixed chimeras receiving BM from A.SW wild-type or RAG(-/-) mice mixed with BM from B10.S wild-type mice. This experiment clearly demonstrated that T and B lymphocytes were indispensable for transferring the susceptible phenotype to disease-resistant recipients. Our findings significantly narrow the cellular expression of genetic polymorphisms controlling the EAM phenotype.

Abstract
Nuclear and mitochondrial genomes combine in ALR/Lt mice to produce systemically elevated defenses against free radical damage, rendering these mice resistant to immune-mediated pancreatic islet destruction. We analyzed the mechanism whereby isolated islets from ALR mice resisted proinflammatory stress mediated by combined cytokines (IL-1beta, TNF-alpha, and IFN-gamma) in vitro. Such damage entails both superoxide and NO radical generation, as well as peroxynitrite, resulting from their combination. In contrast to islets from other mouse strains, ALR islets expressed constitutively higher glutathione reductase, glutathione peroxidase, and higher ratios of reduced to oxidized glutathione. Following incubation with combined cytokines, islets from control strains produced significantly higher levels of hydrogen peroxide and NO than islets from ALR mice. Nitrotyrosine was generated in NOD and C3H/HeJ islets but not by ALR islets. Western blot analysis showed that combined cytokines up-regulated the NF-kappaB inducible NO synthase in NOD-Rag and C3H/HeJ islets but not in ALR islets. This inability of cytokine-treated ALR islets to up-regulate inducible NO synthase and produce NO correlated both with reduced kinetics of IkappaB degradation and with markedly suppressed NF-kappaB p65 nuclear translocation. Hence, ALR/Lt islets resist cytokine-induced diabetogenic stress through enhanced dissipation and/or suppressed formation of reactive oxygen and nitrogen species, impaired IkappaB degradation, and blunted NF-kappaB activation. Nitrotyrosylation of beta cell proteins may generate neoantigens; therefore, resistance of ALR islets to nitrotyrosine formation may, in part, explain why ALR mice are resistant to type 1 diabetes when reconstituted with a NOD immune system.

Abstract
Although it is well established that B-cells are required for the development of diabetes in the nonobese diabetic (NOD) mouse, the nature of their role remains unknown. Herein, we investigate the hypothesis that B-cells in this autoimmune background actively disrupt the tolerant state of those T-cells with which they interact. We demonstrate that NOD B-cells express elevated levels of crucial molecules involved in antigen presentation (including CD21/35, major histocompatibility complex class II, and CD40), alterations that invite the possibility of inappropriate T-cell activation. However, when chimeric animals are generated in which all B-cells are NOD-derived, a tolerant state is maintained. These data demonstrate that although B-cells are required for the development of autoimmunity, they are not sufficient to disrupt established tolerance. Moreover, non-B-cell antigen-presenting cells may be the critical actors in the establishment of the tolerant state; this function may be absent in NOD mice as they are characterized by deficient professional antigen-presenting cell function.

Abstract
The clinical use of autologous stem cell transplants for the treatment of refractory severe autoimmune diseases was preceded by convincing proof of its underlying principle in animal models. The various categories of experimental autoimmune disease in laboratory rodents are briefly described here, and the rationale that was used in the selection of suitable experimental autoimmune diseases for translational research is explained. The two models that provided the bulk of the data needed for designing the initial clinical treatment protocols were adjuvant arthritis (AA) and experimental allergic encephalomyelitis (EAE), which were both induced in Buffalo rats. In this strain, AA is manifested as a chronic, progressive, systemic polyarthritis and EAE as a chronic, remitting/relapsing form of encephalomyelitis resembling multiple sclerosis. Both diseases can be cured with autologous stem cell transplantation provided that adequate conditioning is given and that the disease has not yet progressed to the stage of 'scarring'. It is basically the inflammatory stages that respond well to this therapy. The success of treatment depends on how completely the autoantigen-specific activated T-lymphocytes and memory cells are eradicated. Because of a lack of information on the nature of the autoantigens involved in human disease and on the size of those cell populations in the animal models as well as in humans, this aspect of translation is difficult. The experiments have, however, provided important guidelines. High-dose conditioning regimens yield better results than low-dose conditioning, certain conditioning agents perform better than others, and care should be taken not to reintroduce too many T-cells with the autologous graft. The clinical results obtained so far indicate a high predictive power of these two animal models, which are therefore recommended strongly for additional preclinical studies.

Abstract
The non-obese diabetic (NOD) mouse is a unique and invaluable model of autoimmune disease, in particular type 1 diabetes. Bone marrow transplantation as a therapy for type 1 diabetes has been explored in NOD mice. NOD mice require higher doses of conditioning irradiation for successful allogeneic bone marrow transplantation, suggesting that NOD hematopoietic cells are radioresistant compared to those of other mouse strains. However, studies of hematopoietic reconstitution in NOD mice are hampered by the lack of mice bearing a suitable cell-surface marker that would allow transferred cells or their progeny to be distinguished. In order to monitor hematopoietic reconstitution in NOD mice we generated congenic NOD mice that carry the alternative allelic form of the pan-leukocyte alloantigen CD45. Following irradiation and congenic bone marrow transplantation, we found that the myeloid lineage was rapidly reconstituted by cells of donor origin but substantial numbers of recipient T lymphocytes persisted even after supra-lethal irradiation. This indicates that radiation resistance in the NOD hematopoietic compartment is a property primarily of mature T lymphocytes.

Abstract
Bone marrow or hematopoietic stem cell transplantation is a potential treatment for autoimmune disease. The clinical application of this approach is, however, limited by the risks associated with allogeneic transplantation. In contrast, syngeneic transplantation would be safe and have wide clinical application. Because T cell tolerance can be induced by presenting antigen on resting antigen-presenting cells (APCs), we reasoned that hematopoietic stem cells engineered to express autoantigen in resting APCs could be used to prevent autoimmune disease. Proinsulin is a major autoantigen associated with pancreatic beta cell destruction in humans with type 1 diabetes (T1D) and in autoimmune NOD mice. Here, we demonstrate that syngeneic transplantation of hematopoietic stem cells encoding proinsulin transgenically targeted to APCs totally prevents the development of spontaneous autoimmune diabetes in NOD mice. This antigen-specific immunotherapeutic strategy could be applied to prevent T1D and other autoimmune diseases in humans.

Abstract
Purified hematopoietic stem cells (HSCs) were transplanted into NOD mice to test whether development of hyperglycemia could be prevented. Engraftment of major histocompatibility complex-mismatched HSCs was compared with bone marrow (BM) grafts. HSCs differed from BM because HSCs were more strongly resisted and HSC recipients retained significant levels of NOD T-cells, whereas BM recipients were full donor chimeras. Despite persistent NOD T-cells, all HSC chimeras were protected from hyperglycemia, and attenuation of islet lesions was observed. T-cell selection was altered in allogeneic HSC recipients as demonstrated by deletion of both donor and host superantigen-specific T-cells. Syngeneic and congenic hematopoietic cell transplants were also performed to differentiate the influence of the preparative regimen(s) versus the allografts. Unlike the allogeneic HSC transplantations, syngeneic or congenic grafts did not retard diabetes development. In a pilot study, overtly diabetic NOD mice were cured by co-transplantation of allogeneic HSCs and donor-matched islets. We conclude that allogeneic HSC transplants block allo- and autoimmunity, despite residual host T-cell presence. These data demonstrate for the first time that purified HSC grafts block development of autoimmune diabetes and illuminate how HSC grafts alter thymic and peripheral T-cell responses against auto- and alloantigens.

Abstract
To determine the role of allogeneic, autologous and syngeneic hemopoietic stem cell transplantation (SCTx) as a treatment for severe autoimmune disease (AID) we performed a literature search employing Medline, Cancer Lit and abstract books for reports on transplants for blood disorders and a concomitant AID. All reviews, case reports and abstracts available between June 1977 and September 2001 were used and attempts made to update them by e-mail by the corresponding authors. Disease-free survival (DFS) after allogeneic SCTx for 23 patients with severe aplastic anemia was 78% at 16 years and survival in unmaintained remission of concomitant AID was 64% at 13 years. DFS after allogeneic SCTx for 24 patients with hematologic malignancies was 87% at 15 years and survival in unmaintained remission for concomitant AID was 70% at 11 years. DFS after autologous SCTx for 24 patients with hematologic malignancies was 48% at 6 years and survival in unmaintained remission for concomitant AID was 29% at 3 years. Among 30 patients given allogeneic SCTx 19 developed graft-versus-host disease (GVHD) and 11 did not. Upon clinically justified discontinuation of all immunosuppressive therapy, 3/11 patients without GVHD relapsed with their concomitant AID (freedom of AID-relapse 69% at 9 years), whereas none of 19 patients with GVHD did so (log rank: P = 0.0135). Freedom of AID-relapse was superior after allo SCTx compared to autologous SCTx (89% at 18 years vs 38% at 5 years; log rank: P = 0.0002). Our data suggest that a graft-versus-autoimmunity effect after allogeneic hemopoietic SCTx mediates elimination of autoimmunity.

Abstract
Genes outside the MHC create a general susceptibility to autoimmunity in non-obese diabetic (NOD) mice. Here we describe marked differences in dendritic cell generation in vivo, caused by non-MHC NOD genes. Analyses of splenic dendritic cells from the autoimmunity-prone NOD.H-2(k) mice revealed a relative over-representation of the CD8 alpha(-) subsets, in contrast to the level of these subsets observed in the autoimmunity-resistant B10.H-2(k) congenic strain or other H-2(k) strains. The imbalance towards CD8 alpha(-) dendritic cells was selectively manifested by NOD.H-2(k)-derived cells in radiation chimeras reconstituted with equal mixtures of NOD.H-2(k) and B10.H-2(k) bone marrow cells. In addition to the cell-intrinsic imbalance in dendritic cell subsets, the myeloid lineage overall was intrinsically altered by NOD genes, as this lineage was disproportionately derived from the NOD.H-2(k) donor in mixed chimeras. These results identify a striking effect of non-MHC NOD genes upon the balance of dendritic cell subsets that may contribute to the generalized defects in self-tolerance in the NOD strain.

Abstract
Adoptive transfer of donor immunity has been demonstrated in animals after bone marrow transplantation (BMT). In humans, several autoimmune diseases have been similarly transferred. Although BMT may, per se, be associated with a modulation of the recipient's immune system, which could trigger or even cause autoimmune diseases, both animal experiments and experience with humans show the likeliness of adoptive transfer of donor immunity to the recipient. We describe a patient with multiple myeloma in whom generalized vitiligo developed within 3 months after allogeneic BMT from his HLA-matched sister with vitiligo. We believe that a form of adoptive transfer of donor immunity to the recipient might play a role in the development of vitiligo. In spite of this, neither de novo development of vitiligo in a genetically predisposed patient nor autoimmune phenomena associated with graft-versus-host disease can be completely excluded as a contributing factor for development of vitiligo in our patient. To our knowledge, this is the first case report of transfer of vitiligo after BMT from a donor with vitiligo.

Abstract
Genes outside the MHC create a general susceptibility to autoimmunity in non-obese diabetic (NOD) mice. In this study, we describe marked differences in dendritic cell generation, in vitro, caused by non-MHC NOD genes. Bone marrow cells from NOD.H-2k mice cultured in vitro with GM-CSF and IL-4 generated a reduced yield of dendritic cells when compared to bone marrow cells from B10.H-2k mice. This was due to failure to pass through successive rounds of cell division and elevated levels of apoptosis in NOD.H-2k precursor cells. This aberrant response to GM-CSF and IL-4 was unique to the NOD.H-2k background when compared to bone marrow cells from other H-2k congenic strains, and coculture experiments showed that it was cell-autonomous. Overall, the results described in this study demonstrate a striking effect of non-MHC NOD genes on dendritic cell generation from myeloid precursors derived from the NOD.H-2k strain. These results identify a useful genetic model to explore the regulation of dendritic cell formation. Conceivably, the dysregulation of the dendritic cell system described here may contribute to the generalized defects in self-tolerance in the NOD strain.

Abstract
For poorly understood reasons, the development of autoimmune diabetes in humans and mice is dominantly inhibited by major histocompatibility complex (MHC) class II molecules with diverse antigen-binding sites. We have previously shown that thymocytes expressing a highly diabetogenic I-A(g7)-restricted T-cell receptor (TCR) (4.1-TCR) undergo negative selection in mice carrying one copy of the antidiabetogenic H-2(b) haplotype in an I-A(b)-dependent but superantigen-independent manner. Here, we show that 4.1-TCR-transgenic thymocytes undergo different forms of tolerance in NOD mice expressing antidiabetogenic I-A(d), I-A(g7PD), or I-Ealpha(k) transgenes. The ability of protective MHC class II molecules to induce thymocyte tolerance in 4.1-TCR-transgenic NOD mice correlates with their ability to prevent diabetes in non-TCR-transgenic mice and is associated with polymorphisms within positions 56-67 of their beta1 domains. The 4.1-thymocyte tolerogenic activity of these MHC class II molecules is mediated by dendritic cells and macrophages but not by B-cells or thymic epithelial cells and is a peptide-dependent process. Antidiabetogenic MHC class II molecules may thus afford diabetes resistance by presenting, on dendritic cells and macrophages, tolerogenic peptides to a subset of highly diabetogenic and MHC-promiscuous CD4(+) T-cells that play a critical role in the initiation of diabetes.

Abstract
Transplantation of islet of Langerhans represents a viable therapeutic option for insulin-dependent diabetes mellitus. Dramatic progress has been recently reported with the introduction of a glucocorticoid-free immunosuppressive regimen that improved success rate, namely, insulin independence for 1 year or more, from 8% to 100%. The fate of islet grafts is determined by many concurrent phenomena, some of which are common to organ grafts (i.e. rejection), while others are unique to nonvascularized cell transplants, including transplant cell mass and viability, as well as nonspecific inflammation at the site of implant. Moreover, islet grafts lack clinical markers of early rejection, making it difficult to recognize imminent rejection and to implement intervention with graft-saving immunosuppressive regimens. In the present review, we will address the problems influencing islet graft success and the monitoring of islet cell graft function.

Abstract
BACKGROUND Type 1 diabetes is a cell-mediated autoimmune disease. Successful transplantation of human fetal pancreatic tissue into type 1 diabetic patients must address both autoimmunity and allograft rejection. We investigated whether humoral and cellular responses to islet antigens could be demonstrated in the peripheral blood of type 1 diabetic subjects receiving human fetal pancreatic tissue transplants. METHODS We investigated peripheral blood mononuclear cell (PBMC) responses, using cellular immunoblotting, and autoantibody responses to islet proteins, before transplant and at 3-month intervals after transplant, of nine long-term type 1 diabetes patients (mean disease duration of 21 years) receiving human fetal pancreatic tissue subcutaneously into the abdominal wall without immunosuppression. RESULTS Before transplant, all nine subjects were islet cell autoantibody (ICA)-negative and seven out of nine subjects were glutamic acid decarboxylase autoantibody (GADAb)-positive. After transplant, all subjects became ICA(+) and the two patients who were GADAb(-) before transplant became GADAb(+) after transplant. Maximum PBMC reactivity to separated human fetal pancreatic proteins was observed in four patients 3 months after transplant, in one patient at 6 months, in two patients at 9 months, and in one patient at 12 months after transplant. One subject, who had PBMC reactivity to multiple islet proteins before transplant, continued to respond to multiple islet proteins throughout the study. CONCLUSIONS We conclude that the development in the peripheral blood of ICA, GADAb, and PBMC reactivity to human fetal pancreatic proteins in the trans plant recipients is most consistent with reactivation of the type 1 diabetes disease process.

Abstract
Tlf (T lymphocyte fraction) defines a locus that governs the unusually high fraction of circulating T lymphocytes in the nonobese diabetic (NOD) mouse. We previously mapped Tlf to proximal Chromosome 9 in BC1 mice. Here, Tlf was tine-mapped on Chromosome 9 using 8 markers covering the 43 cM interval from D9Mit90 at 9 cM to D9Mit35 at 52 cM. Markers for diabetic genes on Chromosomes 3, 4, 5, 6, and 17 were also examined for effects on the Tlf phenotype. By both parametric and nonparametric tests. Tlf associated with two areas on Chromosome 9, one with the segment bounded by D9Mit66 (15 cM) and D9Mit2 (17 cM) and a second region near D9Mit71 (29 cM). This linkage pattern was observed both in BC1 and F2 populations. Thus, the Tlf phenotype is possibly governed by two genes on Chromosome 9. An influence by sex on the penetrance of Tlf was evident in that linkage was strongest for female F2 mice and male BC1 mice. One locus controlling the T lymphocyte fraction may be Idd2 since historically a subline of NOD mice with a low T cell fraction showed a low incidence of diabetes. Candidate genes for Tlf are Ets1 and Fli1, proximally and Igif distally.

Abstract
Abstract
Although they share ∼88% of their genome with NOD mice including the H2g7 haplotype, NOR mice remain free of T cell-mediated autoimmune diabetes (IDDM), due to non-MHC genes of C57BLKS/J (BKS) origin. NOR IDDM resistance was previously found to be largely controlled by the Idd13 locus within an ∼24 cM segment on Chromosome 2 encompassing BKS-derived alleles for H3a, B2m, Il1, and Pcna. NOD stocks carrying subcongenic intervals of NOR Chromosome 2 were utilized to more finely map and determine possible functions of Idd13. NOR- derived H3a-Il1 (∼6.0 cM) and Il1-Pcna (∼1.2 cM) intervals both contribute components of IDDM resistance. Hence, the Idd13 locus is more complex than originally thought, since it consists of at least two genes. B2m variants within the H3a-Il1 interval may represent one of these. Monoclonal Ab binding demonstrated that dimerizing with the β2ma (NOD type) vs β2mb isoform (NOR type) alters the structural conformation, but not total expression levels of H2g7 class I molecules (e.g. Kd, Db). β2m-induced alterations in H2g7 class I conformation may partially explain findings from bone marrow chimera analyses that Idd13 modulates IDDM development at the level of non-hematopoietically derived cell types controlling selection of diabetogenic T cells and/or pancreatic β cells targeted by these effectors. Since trans-interactions between relatively common and functionally normal allelic variants may contribute to IDDM in NOD mice, the search for Idd genes in humans should not be limited to functionally defective variants.

Certain major histocompatibility complex (MHC) class II haplotypes encode elements providing either susceptibility or dominant resistance to the development of spontaneous autoimmune diseases via mechanisms that remain undefined. Here we show that a pancreatic beta cell-reactive, I-Ag7-restricted, transgenic TCR that is highly diabetogenic in nonobese diabetic mice (H-2(g7)) undergoes thymocyte negative selection in diabetes-resistant H-2(g7/b), H-2(g7/k), H-2(g7/q), and H-2(g7/nb1) NOD mice by engaging antidiabetogenic MHC class II molecules on thymic bone marrow-derived cells, independently of endogenous superantigens. Thymocyte deletion is complete in the presence of I-Ab, I-Ak + I-Ek or I-Anb1 + I-Enb1 molecules, partial in the presence of I-Aq or I-Ak molecules alone, and absent in the presence of I-As molecules. Mice that delete the transgenic TCR develop variable degrees of insulitis that correlate with the extent of thymocyte deletion, but are invariably resistant to diabetes development. These results provide an explanation as to how protective MHC class II genes carried on one haplotype can override the genetic susceptibility to an autoimmune disease provided by allelic MHC class II genes carried on a second haplotype.

Abstract
To investigate the role of primary T cell repertoire selection in the immunopathogenesis of autoimmune diseases, pure thymic epithelium (TE) from nonobese diabetic (NOD) embryos was grafted into non autoimmune prone newborn C57BL/6 athymic mice. The results show that NOD TE selects host T cell repertoires that establish autoimmunity in otherwise nondiabetic animals. Thus, such chimeras regularly show CD4 and CD8 T cell-mediated insulitis and sialitis, in contrast with syngeneic or allogeneic chimeras produced with TE from nonautoimmune strains. This is the first demonstration that autoimmunity to pancreatic beta cells and salivary glands can be established by the sole alteration of the thymic environment involved in T cell selection, regardless of the nature and presentation of both major histocompatibility complex and tissue-specific antigens on the target organ. These data indicate that T cell repertoire selection by the NOD thymic epithelium is sufficient to induce specific autoimmune characteristics in the context of an otherwise normal host.

Abstract
Insulin dependent diabetes mellitus (IDDM) is likely to be due to the immunologic destruction of the islets of Langerhans. However, the relative importance of expression of a unique set of islet antigens or of differences in immune responses to those antigens in determining susceptibility to auto-immune diabetes is unknown. To a large extent, the reason for this uncertainty is the difficulty in directly identifying islet antigens expressed in vivo. We have studied the relationship between islet antigen expression, immune responsiveness to islet antigens, and the development of diabetes in diabetes induced by multiple low-doses of streptozotocin (STZ) in mice of the H-2d haplotype. We identified the expression of relevant islet antigens by testing the ability of STZ treated islets to induce tolerance to diabetes in C57BL/KsJ mice after intrathymic transplantation. C57BL/KsJ but not BALB/cByJ mice developed hyperglycaemia and insulitis following STZ treatment. Interferon-gamma transcription was detected in intrapancreatic lymphocytes from C57BL/KsJ mice but at lower levels in cell from BALB/cByJ. IL-4 levels were higher in BALB/cByJ than C57BL/KsJ. Intrathymic STZ-treated islets from syngeneic mice induced tolerance to diabetes in C57BL/KsJ mice following transient depletion of mature peripheral T cells, but islets from resistant BALB/cByJ mice did not induce tolerance to disease in C57BL/KsJ mice even though they did cause tolerance to the alloantigens. (C57BL/KsJ x BALB/cByJ)F1 mice developed hyperglycaemia like the susceptible parent following STZ treatment, and islets from these mice induced tolerance to MDSDM when treated with STZ and transplanted intrathymically into C57BL/KsJ. We conclude the expression of islet antigens and the intrapancreatic responses to STZ treated islets differs between mice that are susceptible and resistant to multi-dose streptozotocin induced diabetes mellitus.

Abstract
Central to the autoimmune pathogenesis of IDDM in NOD mice is the MHC class II region. In all models studied to date, expression of NOD MHC class II genes is essential for disease development suggesting a crucial role for I-ANOD-restricted presentation of autoantigen. Protection has been afforded by transgene incorporation of other non-NOD class II genes and many models have been proposed to account for this effect. It is now clear that protection is not achieved by deletion or permanent silencing of all autoreactive T cell clones. It also appears that expression of these genes is required both intra- and extrathymically. It still remains to be determined what role these genes may have in the various compartments and how the autoreactive cells are held in check in protected NOD transgenic mice. Currently, the most likely explanation is that intrathymic expression of non-NOD class II genes is required for the positive selection of class II-restricted immunoregulatory T cells, while peripheral expression is necessary to bring about the interaction of these cells in a tricellular complex with NOD autoantigen-specific T cells and APCs, so that the response can be deviated to a nonpathogenetic one. Whether this process is active or passive is not known.

Abstract
Allophenic mice (embryo aggregation mouse chimeras) enable us to dissect the process of spontaneous autoimmunity under physiological conditions. Our previous experiments showed that the autoimmune process in allophenic mice of the NOD<-->C57B1/6 strain combination does not progress from insulitis to diabetes. One possible explanation for this protection is that H-2 Kd-restricted CD8+ T cells kill only NOD beta cells (Kd,Db) in the chimeric islets, while the B6 beta cells (Kb,Db) are spared from destruction. To test this hypothesis we analysed 22 NOD<-->B10.GD chimeras in which the class I MHC are shared by both parental strains. Therefore all the beta cells in these chimeras express H-2 Kd molecules. Ten allophenic mice were killed at 7 weeks and studied for early pathology. No evidence for intra-islet infiltration was obtained at this age, suggesting that the autoimmune process in NOD<-->B10.GD chimeras is slower than in NOD mice. Twelve chimeras were followed up for 1 year for disease development and all failed to progress to full-blown diabetes, despite the occurrence of intra-insulitis in six out of 12 mice. The lack of disease in NOD<-->B10.GD chimeras demonstrates that class I MHC chimerism does not account for diabetes resistance in NOD-allophenic mice.

Abstract
We have performed extensive analyses of T cell receptor V beta usage in the thymus, the spleen and the infiltrated islets of preclinical non-obese diabetic (NOD) mice. A semiquantitative anchored polymerase chain reaction (An-PCR) protocol has been developed for this purpose. The validity of the method has been first assessed by antibody staining with a panel of anti-V beta monoclonal antibodies (mAb). The results obtained by An-PCR are accurate, reproducible, and in good agreement with cell surface protein staining. A strict comparison between thymus and spleen repertoires reveals no major V beta-specific deletion except the already reported V beta 3 deletion due to Mtv-3. Certain V beta such as V beta 15, 18, 20 are found with a low frequency in the spleen, but the fact that they are also scarce in the thymus probably reflects a poor availability of these genetic elements during beta chain rearrangement rather than negative selection. Other V beta, such as V beta 2, V beta 12 and V beta 14 are significantly more abundant in the spleen than in the thymus. This finding was confirmed by mAb staining for V beta 2 and V beta 14. The expansion asymmetrically affects the CD4+ subset and can be traced back to the mature, single-positive thymocyte subset, suggesting an intrathymic positive selection event. V beta repertoires in infiltrated islets of 13- and 18-week-old, non-diabetic mice are polymorphic. Practically all the V beta found in the peripheral lymphoid tissues are present in the islets, in similar proportions. The major exception is V beta 12, one of the V beta which is subject to expansion during intrathymic differentiation and which is further augmented in the islets, both at 13 and 18 weeks. This increase probably reflects further peripheral amplification of the V beta 12-bearing subset due to encounter with the same ligand as in the thymus or with a cross-reactive motif. Finally, the nucleotide sequencing of all the V beta segments in usage in the NOD strain confirms the absence of allelic polymorphism of V beta-coding regions.

Abstract
Flow cytometry was used to track the in vivo migration of PKH26-labeled donor spleen cells from diabetic NOD mice that were injected into non-diabetic recipient NOD mice. Flow cytometric analysis of recipient mouse tissues revealed that the donor cells were present in the peripheral blood, spleen and lymph nodes 24 h following injection and could still be detected after 28 days. PKH26(+) cells were also detectable in the pancreas 7 days after injection. Phenotypic analysis of the PKH26(+) cells that migrated into these target organs and tissues showed that the major cell population detected was Thy1.2(+) T-lymphocytes, predominantly the Thy1.2(+)/L3T4(+) subpopulation, but Thy1.2(+)/Lyt2(+) cells as well as B220(+) cells (B lymphocytes) were also present.

Abstract
We have previously produced lines of rats transgenic for HLA-B27 and human beta 2-microglobulin (h beta 2m) that develop a progressive inflammatory disease sharing many clinical and histologic features with the B27-associated human spondyloarthropathies, including gut and male genital inflammation, arthritis, and psoriasiform skin lesions. Other transgenic lines that express lower levels of B27 and h beta 2m remain healthy. To investigate the cellular basis for the multisystem inflammatory disease in these rats, we transferred lymphoid cell populations from disease-prone transgenic lines to irradiated disease-resistant transgenic and nontransgenic recipients. In recipients of cells from two different disease-prone lines, successful transfer required engraftment of bone marrow cells. Transfer of disease with fetal liver cells suggested that neither mature effector cells nor active disease in the donors was necessary for induction of disease in the recipients. Remission of the spontaneous disease in irradiated transgenic rats was induced by engraftment of nontransgenic bone marrow. These results suggest that the expression of HLA-B27 in bone marrow-derived cells alone is sufficient for the development of B27-associated disease, and that disease transfer requires engraftment of a bone marrow precursor cell for which mature cells in spleen or in lymph node cannot substitute.

Abstract
Insulin-dependent diabetes was observed in a woman, aged 29, 4 years after transplantation of bone marrow from her HLA-identical brother with insulin-dependent diabetes. Both had classic symptoms and insulin dependency from onset. At diagnosis of diabetes the recipient was positive for high-titre islet cell antibodies (ICA) whereas she had been ICA negative before transplantation. Chromosomal analyses verified that all circulating leucocytes were of male donor type. These findings suggest transfer of insulin-dependent diabetes by bone marrow cells and confirm the immune nature of the disease.

Abstract
Endogeneous retroviral expression in beta cells is a feature of prediabetes in nonobese diabetic (NOD) mice. The purpose of this study was to characterize the class-specific pattern of retroviral gene expression in NOD/Lt beta cells versus a related, but diabetes-resistant strain, NON/Lt. Electron microscopic comparison of beta cells from both strains indicated low constitutive expression of the intracisternal type A (IAP) retroviral class. However, NOD beta cells, in contrast to NON beta cells, expressed an additional intracisternal retroviral form resembling a type C particle. Antibodies against both IAP and type C were detected in NOD, with the humoral response to type C, but not IAP, preceding decline in beta cell function. RNA was extracted from freshly isolated islets from NOD and NON males. Comparative Northern blot analysis of total type C retroviral gene expression using a gag-pol DNA probe corroborated expression of endogenous type C proviruses in both NOD and NON islet cells and thymus. Use of class-specific retroviral probes identified the class of expressed endogenous retrovirus distinguishing the two inbred strains. The single ecotropic provirus present in both the NOD and NON genome (Emv-30) was not expressed in islets or thymus of either strain. Comparison of endogenous xenotropic provirus content by Southern blot analysis revealed two unique xenotropic loci (Xmv-65, -66) in NOD; 8.4 and 3.0 kb xenotropic envelope (env) RNA transcripts were detected in NOD, but not NON islets and thymus. NON contained three xenotropic loci common to other inbred strains (Xmv-21, -25, and -28). Both strains were partially characterized for content of recombinant (polytropic and modified polytropic) proviruses. IAP RNA expression was common to both NOD and NON islets and hence could not be specifically associated with the unique intracisternal type C particle found in NOD, but not NON beta cells. In conclusion, this study shows that expression of xenotropic type C but not IAP distinguishes retroviral activity in NOD/Lt versus NON/Lt beta cells. The potential pathogenic role of retroviral gene expression in NOD beta cells is discussed.

Abstract
Diabetes in NOD mice represents the end stage of a genetically-programmed autoimmune process mediated by T lymphocytes and directed against insulin-producing beta cells. We have shown in a previous study that the course of the disease is significantly inhibited in NOD mice which have been made tolerant at birth to foreign histocompatibility antigens. This early T cell manipulation results in a significant delay of disease onset, reduced overall incidence and less severe alterations of islet cells. In order to characterize better the nature of the foreign tolerogenic determinants responsible for this protection, we have now examined separately the contribution of MHC and non-MHC antigens. Two lines of congenic mice were used as donors of tolerogenic cells, NOD.H-2b, which differ from NOD by the MHC-encoded antigens only, and B10.H-2g7, which differ by all the minor histocompatibility antigens encoded by the B10 background, but which share with NOD mice the same MHC haplotype. Our results show that NOD recipients of F1 semi-compatible cells become specifically tolerant to the set of alloantigens to which they were neonatally exposed. Unresponsiveness, assessed by lack of CTL generation, is profound and specific. Yet, despite the fact that distinct sets of alloreactive T cell precursors are silenced, mice made tolerant indifferently to major or minor histocompatibility antigens are significantly protected against overt diabetes. These results could mean that each set of MHC and non-MHC encoded determinants can independently cross-tolerize a sufficient proportion of the autoreactive repertoire to slow the natural course of the disease. Alternatively, neonatally-acquired tolerance might induce polyclonal activation of the immune system resulting in the suppression or the immunodeviation of potentially harmful, autoreactive T cell clones.

Abstract
The development of autoimmune diabetes in the nonobese diabetic (NOD) mouse is controlled by multiple genes. At least one diabetogenic gene is linked to the major histocompatibility complex (MHC) of the NOD and is most likely represented by the two genes encoding the alpha and beta chains of the unique NOD class II molecule. Three other diabetogenic loci have recently been identified in the NOD mouse and are located on chromosomes 1, 3, and 11. In addition to the autoimmune diabetes which is caused by destruction of the insulin-producing beta cells in the pancreas, other manifestations of autoimmunity are seen in the NOD mouse. These include mononuclear cell inflammation of the submandibular and lacrimal glands, as well as the presence of circulating autoantibodies. To determine the effect of the non-MHC diabetogenic genes on the development of autoimmunity, we constructed the NOD.B10-H-2b (NOD.H-2b) strain, which possesses the non-MHC diabetogenic genes from the NOD mouse, but derives its MHC from the C57BL/10 (B10) strain. The NOD.H-2b strain does not develop insulitis, cyclophosphamide-induced diabetes, or spontaneous diabetes. It does, however, develop extensive lymphocytic infiltrates in the pancreas and the submandibular glands that are primarily composed of Thy 1.2+ T cells and B220+ B cells. In addition, autoantibodies are present in NOD.H-2b mice which recognize the "polar antigen" on the insulin-secreting rat tumor line RINm38. These observations demonstrate that the non-MHC genes in the NOD strain, in the absence of the NOD MHC, significantly contribute to the development of autoimmunity. The contribution of a single dose of the NOD MHC to autoimmunity was assessed with a (NOD x NOD.H-2b)F1 cross. Although only approximately 3% of F1 females developed spontaneous diabetes, approximately 50% of both female and male F1 mice developed insulitis, and 25% of females and 17% of males became diabetic after treatment with cyclophosphamide. These data demonstrate that the MHC-linked diabetogenic genes of the NOD mouse are dominant with decreasing levels of penetrance for the following phenotypes: insulitis greater than cyclophosphamide-induced diabetes greater than spontaneous diabetes.

Abstract
Expression of diabetes susceptibility genes at the hemopoietic stem cell level is sufficient for the development of the disease in nonobese diabetic (NOD) mice. This work investigated whether the defects that reside within the stem cells have consequences on the homeostasis of the stem and progenitor cell compartments. The fraction of cyclically active stem cells, or spleen colony-forming units (CFU-s), is enlarged, and their differentiation toward megakaryocytopoiesis seems to be enhanced in NOD mice at 3 and 10 weeks of age as compared to C57BL/6 mice. Whereas colony-forming unit assay (CFU-A) numbers are normal in the bone marrow, they are significantly increased in the spleen of NOD mice. A strain-dependent difference in granulocyte-macrophage colony-forming cell (GM-CFC) numbers was observed; they were higher in NOD mice than in B6 mice of three and ten weeks of age. These results suggest that autoimmune type 1 diabetes mellitus of the NOD mouse is accompanied by disorders of myelopoiesis and megakaryopoiesis. This observation is in keeping with the role of macrophages in the development of diabetes and with the hyperactivity of diabetic platelets.

Abstract
We have analyzed the T cell receptor (TcR) V alpha and TcR V beta regions in the spontaneous mouse model for insulin-dependent diabetes mellitus, the NOD mouse, and compared it to the regions in the two sister strains, the NON and CTS strains. Based on restriction fragment length polymorphism analysis the TcR V alpha region in the NOD mouse is essentially identical to that of the SJL/J strain. In contrast both the NON and CTS strains have a unique TcR V alpha haplotype. Whereas the NOD and NON strains apparently contains all the TcR V beta genes, the CTS mouse has three deletions in the V beta region. Our analysis does not give any indications for the diabetic phenotype of the NOD mouse.

Abstract
The mechanisms contributing to the development of autoimmune insulin-dependent diabetes mellitus have been analyzed in allophenic mouse chimeras of the NOD in equilibrium with C57BL/6 strain combination (where NOD is nonobese diabetic). Occurrence of lymphoid cell infiltration (insulitis) in pancreatic islets was observed in the majority of such chimeras. The development of insulitis was found to correlate with major histocompatibility complex chimerism in lymphoid cells and in thymus cortical regions. Chimeras with more than 50% of C57BL/6 lymphoid cells rarely developed insulitis. Our data suggest that the correlation with the thymic cortical region is absolute. Thus, all individuals displaying NOD or NOD/C57BL/6 thymic cortical regions developed insulitis, whereas we have not observed insulitis in chimeras with only C57BL/6 thymic cortical regions. Thus the positive selection of T cells appears to play a crucial role in the development of insulin-dependent diabetes mellitus.
