Abstract
Murine syngeneic graft-versus-host disease (SGVHD) results in chronic colon and liver inflammation following syngeneic bone marrow transplantation (BMT) and treatment with the calcineurin inhibitor, cyclosporine A (CsA). SGVHD was initially thought to arise as a result of an autoreactive immune response, but more recently it has been shown that enhanced antimicrobial responses develop in SGVHD mice. Consequently, we performed studies to analyze the role of the microbiota in the development of murine SGVHD. Treatment with broad-spectrum antibiotics eliminated disease-associated inflammatory immune responses and pathology, linking the role of the microbiota and microbial-specific immunity to the development of murine SGVHD. In a broader context, these results bring into question the role that anti-microbial immune responses play in post-transplant immune pathologies that develop following allogeneic stem cell transplantation and use of calcineurin inhibitors.

Abstract
Engraftment syndrome (ES) encompasses a continuum of periengraftment complications after autologous hematopoietic stem cell transplantation. ES may include noninfectious fever, skin rash, diarrhea, hepatic dysfunction, renal dysfunction, transient encephalopathy, and capillary leak features, such as noncardiogenic pulmonary infiltrates, hypoxia, and weight gain with no alternative etiologic basis other than engraftment. Given its pleiotropic clinical presentation, the transplant field has struggled to clearly define ES and related syndromes. Here, we present a comprehensive review of ES in all documented disease settings. Furthermore, we discuss the proposed risk factors, etiology, and clinical relevance of ES. Finally, our current approach to ES is included along with a proposed treatment algorithm for the management of this complication.

Abstract
Graft-versus-host disease (GVHD) is an underappreciated complication of autologous hematopoietic stem cell transplantation (AHSCT) that can affect the skin, gastrointestinal tract, and liver. The development of this rare condition is probably due to an impairment of immunologic tolerance that can occur spontaneously through T-cell dysregulation, possibly from intensive conditioning chemotherapy regimens, or intentionally through administration of cyclosporine in the hopes of promoting an antitumor response. We present the case of a 2-year-old boy with metastatic neuroblastoma who spontaneously developed autologous GVHD after AHSCT. Severe pruritus and an inability to taper his oral steroids without a disease flare marked his disease. Eventually partial relief was achieved with initiation of cyclosporine and a strict soak and smear protocol using topical triamcinolone 0.1% ointment.

Abstract
To determine the role of regulatory T lymphocytes (Tregs) in the pathogenesis of human chronic graft-versus-host disease (GVHD) and its clinical resolution, we evaluated long-term recipients of pediatric allogeneic hematopoietic stem cell transplantation (HSCT). Seventy-one recipients were evaluated, 30 of whom had a history of chronic GVHD, including 16 with active chronic GVHD and 14 with resolved chronic GVHD. There were no significant clinical differences and no differences in the frequency of Tregs (CD4(+), CD127(-), CD25(+)) between the recipients with active chronic GVHD and those with resolved chronic GVHD. Using the Miyara/Sakaguchi classification scheme to identify functional Tregs, a decreased frequency of functional resting Tregs (rTregs) was identified in recipients with active chronic GVHD (P = .009 compared with normal donors; P = .001 compared with HSCT recipients without history of chronic GVHD; P = .005 compared with recipients with resolved chronic GVHD). The frequency and number of recent thymic emigrants in rTregs were normal in recipients with resolved chronic GVHD, but persistently decreased in recipients with active chronic GVHD. These results support the hypothesis that the reestablishment of normal numbers of functional rTregs is required for the clinical resolution of chronic GVHD.

Abstract
Chronic GVHD is a major cause of morbidity and mortality in allogeneic stem cell transplantation recipients and typically develops from antecedent acute GVHD. In contrast to acute GVHD, chronic GVHD has much broader tissue involvement and clinical manifestations that bear striking similarity to what is observed in autoimmune diseases. How autoimmunity arises out of alloimmunity has been a longstanding unresolved issue. To address this question, in the present study, we performed a comprehensive analysis of the clonotypic T-cell response using complementary murine models that simulate what occurs during the transition from acute to chronic GVHD. These studies revealed repertoire skewing and the presence of high-frequency clonotypes that had undergone significant in vivo expansion, indicating that GVHD-associated autoimmunity was characterized by antigen-driven expansion of a limited number of T-cell clones. Furthermore, we observed that T cells with identical TCRβ CDR3 nucleotide sequences were capable of recognizing donor and host antigens, providing evidence that the loss of self-tolerance during acute GVHD leads to the emergence of self-reactive donor T cells that are capable of recognizing nonpolymorphic tissue or commensally derived antigens. These data provide a mechanistic framework for how autoimmunity develops within the context of preexisting GVHD and provide additional insight into the pathophysiology of chronic GVHD.

Abstract
Explorative knowledge of cellular and molecular mechanisms of immune function and regulation has provided optimism in developing cancer immunotherapy. However, three decades of experimental and clinical investigations to offer powerful immunotherapeutic strategies against solid tumors, with the possible exception of monoclonal antibody-targeted therapies, have not succeeded in significantly prolonging patient survival. Nonspecific immune approaches, including cytokine-based therapies and allogeneic hematopoietic stem cell transplantation, have so far produced consistent, although limited, results. In this review, we present the developments of cell transfer-based strategies that, in preclinical studies, have demonstrated potential efficacy, but have only established tumor regression in limited numbers of patients. The key to success demands creative combinations of tumor antigens, adjuvance, gene modification and various administration strategies in the development of cell-based therapies together with other cancer-treatment principles, often in a stepwise 'space-rocket-type' approach. Combined efforts of several scientific disciplines, such as tumor biology and immunology, as well as cell and gene research in transplantation, will open new venues. New regulation for clinical trials with advanced therapy medicine products to ensure patient safety will be highlighted.

Abstract
Graft-versus-host disease (GVHD) is a major complication of allogeneic bone marrow or hematopoietic stem cell transplantation. GVHD is thought to be primarily due to the response of mature T cells transferred along with the bone marrow graft to foreign histocompatibility antigens expressed on host tissues. Recent studies, however, have challenged this paradigm set forth in the 1960s and have suggested that self-MHC class II antigens can be recognized in GVHD. Many questions still remain unanswered particularly in regard to the role of immune reconstitution, the ability to recognize and discriminate self and the re-establishment of self-tolerance. In fact, the failure to re-establish tolerance to self can lead to systemic autoimmunity that may exacerbate or even mimic GVHD. The present review summarizes our studies in autologous GVHD characterizing the underlying immune mechanisms and their potential impact in allogeneic hematopoietic stem cell transplantation.

Abstract
Breast and ovarian cancer continue to be a significant source of morbidity and mortality. Improved understanding of signalling pathways related to growth and apoptosis has led to targeted treatments and modest improvement in long term outcomes. However, it has become increasingly clear that tumor factors alone are not the sole determinants of outcome in patients with breast and ovarian cancer. The tumor microenvironment and other immunologic host processes play an integral role in the overall interactions between disease, host and treatment. Cytokines play a major role in the immune response to tumors. Single nucleotide polymorphisms (SNPs) in the regulatory or coding regions of many cytokine genes lead to functional alterations in the transcriptional regulation of these genes or the proteins they encode. This review examines the current literature linking functional variants in cytokine and other immune genes to outcomes in breast and ovarian cancer. We have focused on those involved in the proinflammatory response (IL-6, TNF-alpha), apoptosis (TGF-beta, Fas, FasL, C1QA), angiogenesis (IL-8) and autoimmunity (IL-10). While much remains to be learned about the mechanisms underlying these variants and their impact on tumor behavior, this area holds promise for future development of prognostic profiles and therapeutics exploiting the immune response.

Abstract
A phase I/II trial evaluated early administration and dose escalation of interleukin (IL)-2 with granulocyte macrophage colony stimulating factor (GM-CSF) post-transplant. Following melphalan (200 mg/m(2)) and an autologous transplant, IL-2 was initiated (day 0) and continued for 4 weeks. GM-CSF (250 mcg/m(2)/day) began on day 5. Fifteen of 19 patients completed therapy. No treatment-related deaths occurred. IL-2 (1 x 10(6) IU/m(2)/day) was not tolerated in two of six patients due to > or =grade 3 fatigue/diarrhea (n=1) or supraventricular tachycardia (n=1). The maximum tolerated dose of IL-2 was 6 x 10(5) IU/m(2)/day; this dose was well tolerated by 11 of 13 patients. Neutrophil and platelet engraftment occurred on day 13 (median; range 10-17 days) and day 13 (median; range 0-74 days), respectively. When compared to control patients, there was a marked increase in the number of CD3+ T cells (P=0.005), CD4+ T cells (P=0.01), CD8+ T cells (P=0.001) and CD4+CD25+Treg cells (P=0.015) post-transplant. Cytotoxicity directed against myeloma cells was markedly increased when compared to control patients (P=0.017). This unique trial design using early administration of IL-2 with GM-CSF during the period of lymphodepletion, demonstrated a marked increase in the number and function of early cytotoxic effector T cells, without suppression of engraftment.

Abstract
OBJECTIVE Mixed chimerism after allogeneic bone marrow transplantation (BMT) promotes immunologic tolerance. Graft-vs-host disease (GvHD) can occur when immunosuppressive control of the graft fails. Here we evaluate the influence of concurrent immunosuppression after irradiation-based induction therapy on development of tolerance and GvHD. METHODS Conditioning was performed by different doses of total body irradiation (TBI) in a major histocompatibility complex (MHC) class II disparate rat BMT model. Animals received subsequent immunosuppression with either cyclosporine A (CsA) or sirolimus. Nonresponsiveness toward donor and recipient antigens was demonstrated by development of mixed chimerism and/or GvHD. RESULTS Administration of 10 Gy of TBI prior to BMT alone was associated with severe GvHD. Induction therapy with 8 Gy of TBI alone led to graft rejection in the long-term. Two weeks of immunosuppression with CsA after 8 Gy of TBI resulted in transient chimerism, but was finally associated with a combination of fatal GvHD and graft rejection. Six gray of TBI with CsA treatment for 14 or 28 days caused only mild GvHD, but did not lead to stable chimerism. In contrast, treatment with sirolimus was associated with stable chimerism after 8 Gy of TBI (14-day course) and 6 Gy of TBI (28-day course) accompanied by a low incidence of GvHD. CONCLUSIONS In contrast to CsA, sirolimus facilitates development of tolerance after MHC class II disparate BMT and irradiation-based conditioning, with a low risk of GvHD. Therefore, sirolimus has promising characteristics for inclusion in immunosuppressive protocols.

Abstract
Cord blood is currently used as an alternative to bone marrow as a source of stem cells for hematopoietic reconstitution after ablation. It is also under intense preclinical investigation for a variety of indications ranging from stroke, to limb ischemia, to myocardial regeneration. A major drawback in the current use of cord blood is that substantial morbidity and mortality are associated with pre-transplant ablation of the recipient hematopoietic system. Here we raise the possibility that due to unique immunological properties of both the stem cell and non-stem cell components of cord blood, it may be possible to utilize allogeneic cells for regenerative applications without needing to fully compromise the recipient immune system. Issues raised will include: graft versus host potential, the immunogenicity of the cord blood graft, and the parallels between cord blood transplantation and fetal to maternal trafficking. The previous use of unmatched cord blood in absence of any immune ablation, as well as potential steps for widespread clinical implementation of allogeneic cord blood grafts will also be discussed.

Abstract
Graft-versus-host (GVH) disease (GVHD) continues to be a major life-threatening complication after allogeneic bone marrow transplantation. Considerable progress has been made elucidating the pathophysiology of acute GVHD. Mature donor T cells transferred along with the marrow graft directly recognize antigenic differences on antigen-presenting cells of the host. Once activated, donor antihost-specific T cells can mediate tissue destruction. Interestingly, the failure to clonally delete autoreactive T cells in the thymus can also lead to an autoimmune syndrome mimicking the pathology of GVHD. Negative selection in the thymus may be compromised either by damage to the thymic epithelium (because of a direct attack by donor antihost alloreactive T cells) or by the use of immunosuppressive drugs that inhibit clonal deletion. An important component underlying GVHD mediated by either alloreactive or autoreactive T cells is the absence of a competent peripheral regulatory system. Studies in animal model systems clearly indicate that regulatory T cells play a vital role in down-regulating GVHD and are critically important for the establishment of active dominant tolerance to both allo- and self-major histocompatibility complex antigens. Although multiple populations of cells appear to participate in this process, CD4(+) regulatory T cells that innately express CD25(+) appear to orchestrate the regulatory control of the immune response. Evidence for regulatory T cells in clinical bone marrow transplantation, however, remains rudimentary. The recent identification that CD4(+)CD25(+) regulatory T cells preferentially express the Foxp3 nuclear transcription factor and the development of molecular reagents to isolate antigen-specific T cells have provided unique opportunities to explore immunoregulatory mechanisms after clinical marrow transplantation. Recent studies in recipients of clinical bone marrow transplantation suggest that antigen-specific CD4(+)CD25(+)Foxp3(+) T cells play a vital role in the regulatory control of GVH reactions mediated by both alloreactive and autoreactive lymphocytes. These regulatory T cells also appear to facilitate the establishment of donor antihost and donor antidonor (self) tolerance.

Abstract
A high incidence of autologous graft-versus-host-disease (auto-GVHD) was observed after an alemtuzumab-containing conditioning regimen and autologous stem cell transplantation (auto-SCT) for chronic lymphocytic leukemia (CLL). Skin rash developed in almost all surviving patients (87%). In 7 patients (58%), a diagnosis of auto-GVHD was made (compared with 0% after TBI/Cy; P = .01). All patients with auto-GVHD required immunosuppression, and 3 of 7 were hospitalized because of GVHD. The median duration of GVHD was 517 days (range, 60-867 days). Auto-GVHD was associated with an abnormally high CD4/CD8 ratio because of severe depletion of CD8(+) T cells, pointing to a potential pathomechanism. High non-relapse-related mortality led to the discontinuation of the trial. Current results do not support the use of high-dose alemtuzumab combined with total body irradiation (TBI) and autologous stem cell transplantation (auto-SCT). However, the addition of alemtuzumab led to improved disease control at the molecular level. Longer follow-up will show whether the GVHD-like syndrome may contribute to prolonged minimal residual disease (MRD) negativity.

Abstract
Acute graft-versus-host disease (GVHD), initiated by the reaction of donor T lymphocytes against nonshared recipient antigens, typically leads to a clinical syndrome characterized by cutaneous eruptions and intestinal and hepatic dysfunction. These three organ systems are considered in the clinical grading of acute GVHD. However, other targets may be involved. With conventional transplant conditioning regimens and in vivo prophylaxis, GVHD becomes clinically manifest within 2 to 4 weeks. With reduced-intensity conditioning, the onset of acute GVHD may be delayed until 2 to 3 months after transplantation. Hyperacute GVHD may occur within a week of transplantation after severely human leukocyte antigen (HLA)-mismatched transplants or transplants without GVHD prophylaxis. There is no reliable laboratory test for acute GVHD, and the diagnosis is based on clinical assessment.

Abstract
In antigen-presenting cells (APCs), loading of major histocompatibility complex class II (MHC II) molecules with peptides is regulated by invariant chain (Ii), which blocks MHC II antigen-binding sites in pre-endosomal compartments. Several molecules then act upon MHC II molecules in endosomes to facilitate peptide loading: Ii-degrading proteases, the peptide exchange factor, human leukocyte antigen-DM (HLA-DM), and its modulator, HLA-DO (DO). Here, we review our findings arguing that DM stabilizes a globally altered conformation of the antigen-binding groove by binding to a lateral surface of the MHC II molecule. Our data imply changes in the interactions between specificity pockets and peptide side chains, complementing data from others that suggest DM affects hydrogen bonds. Selective weakening of peptide/MHC interactions allows DM to alter the peptide repertoire. We also review our studies in cells that highlight the ability of several factors to modulate surface expression of MHC II molecules via post-Golgi mechanisms; these factors include MHC class II-associated Ii peptides (CLIP), DM, and microbial products that modulate MHC II traffic from endosomes to the plasma membrane. In this context, we discuss possible mechanisms by which the association of some MHC II alleles with autoimmune diseases may be linked to their low CLIP affinity.

Abstract
Several clinical trials evaluating the induction of autoimmune graft-versus-host disease (GVHD) after autologous bone marrow transplantation (BMT) as antitumor immunotherapy have shown that autologous GVHD is associated with increased production of interleukin (IL)-10. The induction of autologous GVHD also segregated with single nucleotide polymorphisms in the IL-10 promoter region (IL-10 -592 and IL-10 -1082 ) and with CA repeats in the first intron of the interferon (IFN)-gamma gene. Polymorphisms within these promoter regions can significantly modify the cytokine response because of differential transcription factor efficiency. This study evaluated the relationship between inheritance of polymorphisms within the IL-10 promoter and in the IFN-gamma gene and the overall survival of patients who received autologous BMT for metastatic breast cancer. Peripheral mononuclear cells from 87 women enrolled in 3 autologous BMT (plus induction of autologous GVHD) clinical trials were examined. By using a Cox proportional hazard model, trends in survival after autologous BMT were analyzed. The model included inheritance polymorphisms of IL-10 -592 , IL-10 -1082 , CA repeats within the first intron of the IFN-gamma gene, estrogen and progesterone receptor status, and stage of disease. Increased survival was significantly associated with patients having the IL-10 -592 promoter allele associated with high IL-10 production (hazard ratio, 0.23; 95% confidence interval, 0.09-0.55; P = .001). The effect of the strong IL-10 promoter allele on survival seems to be independent of the development of clinical autologous GVHD. However, decreased survival was significantly associated with patients having CA repeats associated with higher IFN-gamma transcription (hazard ratio, 2.34; 95% confidence interval, 1.21-4.54; P = .011). Inheritance of specific alleles that modify IL-10 and IFN-gamma production may have unexpected effects on the efficacy of immune-based strategies after autologous BMT. Additional studies are necessary to further define the influence of IL-10 and IFN-gamma on the immune response after BMT.

Abstract
The administration of cyclosporin A (CsA) after autologous stem cell transplantation (SCT) paradoxically elicits a systemic autoimmune syndrome that resembles graft-versus-host disease (GVHD); this is termed autologous GVHD (autoGVHD). Although dominated by activated CD8+ cytotoxic T lymphocytes, the complex cellular reaction also includes CD4+ T cells and involves multiple effector mechanisms. To determine the temporal development and relative importance of these mechanisms in autoGVHD, perforin/granzyme, Fas ligand (FasL), interferon-gamma (IFN-gamma), tumor necrosis factor (TNF)-alpha, and interleukin-18 gene expression in peripheral blood mononuclear cells was examined in 36 patients treated with CsA after SCT. Quantitative real-time polymerase chain reaction analysis revealed that perforin/granzyme B, TNF-alpha, and interleukin-18 messenger RNA (mRNA) levels in peripheral blood mononuclear cells from patients in whom autoGVHD developed were markedly higher (and temporally associated with the onset of autoaggression) compared with the levels detected in healthy individuals and in control, non-CsA-treated SCT patients. It is interesting to note that patients in whom autoGVHD did not develop also demonstrated increased mRNA levels for these cytokines: however, expression was substantially lower compared with that in patients with autoGVHD. It is important to note that IFN-gamma mRNA levels were selectively increased in CD8+ cells only from patients in whom autoGVHD developed. The development of autocytolytic T cells in autoGVHD correlated with increased expression of perforin, IFN-gamma, and TNF-alpha mRNA. Furthermore, enhanced autoreactive T-cell activity and the induction of autoGVHD was also concordant with perforin and TNF-alpha mRNA upregulation in CD4+ cells. Surprisingly, FasL mRNA levels were significantly decreased, with a progressive loss of FasL mRNA expression as autocytolytic activity increased. These findings suggest that IFN-gamma/perforin-based CD8+ cytotoxic T lymphocytes seem to play a dominant role in autoGVHD and that TNF-alpha/perforin-based CD4+ cells may amplify this autoaggressive syndrome. The FasL pathway may play an important role in the regulation of this immune syndrome.

Abstract
Administration of cyclosporine after autologous bone marrow transplantation elicits a T-lymphocyte autoaggression syndrome with remarkable similarity to graft-versus-host disease (GVHD). This syndrome, termed syngeneic GVHD (SGVHD), with both acute and chronic phases, is mediated by a restricted repertoire of autoreactive T cells that promiscuously recognize major histocompatibility complex (MHC) class II determinants in association with a peptide from the invariant chain (MHC class II-invariant chain peptide; CLIP). This study evaluated and compared antigen-specific autoreactive T cells during acute and chronic SGVHD ex vivo isolated with a soluble MHC class II immunoglobulin molecular construct. This approach allows for the direct assessment of the functional behavior of the effector T cells without potential modification by in vitro culture. Two major subsets were detected that had overlapping specificity recognizing the MHC class II-binding domain of CLIP but that were differentially dependent on the N- and C-terminal flanking domains of this peptide. The N- and C-terminal subsets were primarily associated with acute and chronic SGVHD, respectively. The cytokine profiles of the CLIP-reactive T cells, however, were most informative and closely correlated with the onset and progression of disease. Levels of type 1 cytokine, particularly interferon-gamma, messenger RNA (mRNA) production, assessed by quantitative polymerase chain reaction, were dominant during acute SGVHD, whereas chronic SGVHD was associated with type 2 cytokine mRNA production. Although there was a dramatic polarization with respect to cytokine production, only subtle changes in antigen specificity could be detected. Unexpectedly, the functional behavior within the antigen-specific effector cell populations is not fixed and seems to change as the disease progresses to the chronic phase. Concordant with the evolution of the effector T-cell response is a differential loss in B7.1 mRNA expression in the N-terminal CLIP-reactive T-cell subset that may reflect the regulation of this autoimmune response. Of additional interest, autoreactive T cells producing interleukin-10 mRNA were detected in both acute and chronic SGVHD, suggesting that this cytokine may play an important but perhaps paradoxical role in both the onset and progression of this experimental autoaggression syndrome.

Abstract
Graft-versus-host disease (GVHD) is characterized by an impairment of mechanisms that underlie the development of immunologic tolerance. Although the cytokine storm associated with GVHD leads to expression of cell surface markers on both effector and regulatory T cells, regulatory CD4+ T cells that play an instrumental role in the maintenance of tolerance appear to uniquely express the Foxp3 transcriptional repressor. Foxp3 mRNA expression was significantly decreased in peripheral blood mononuclear cells from patients with either allogeneic GVHD or autologous GVHD compared with patients without GVHD. Expression of Foxp3 negatively correlated with the severity of GVHD but positively correlated with recent thymic emigrants. The results suggest that defective thymic function contributes to the impaired reconstitution of immune regulatory mechanisms following transplantation. The decrease in regulatory mechanisms after transplantation appears to provide an environment permissive to the development of GVHD.

Abstract
The prognosis for patients with non-Hodgkin's lymphoma (NHL) and advanced Hodgkin's disease (HD) who relapse following autologous transplant is poor. We report on a pilot study designed to evaluate the feasibility of using Cyclosporin A and interferon alpha to induce autologous GVHD following a second autologous transplant for relapsed lymphoma. In all, 10 patients entered the study with median age 46.5 years. Diagnosis was NHL (n=7) or Hodgkin's lymphoma (n=3). All had relapsed from a prior autologous transplant. The second transplant was well tolerated by all patients. Histological changes consistent with cutaneous GVHD developed in 30% of patients at a median of 22.5 days from transplant and settled spontaneously in all cases. Five patients have died (four from progressive disease) at a median 7 months from second transplant. Five patients are still alive and in complete remission at a median of 20 months from transplant. Median overall survival for the group is 13.5 months and median relapse-free survival has not been reached at 42 months. This is a well-tolerated regimen for use in this poor-risk group of patients with lymphoma. The overall survival and event-free survival are encouraging, however further studies are necessary.

Abstract
Syngeneic graft-vs-host disease (SGVHD) develops following lethal irradiation, reconstitution with syngeneic bone marrow, and treatment with a 21-day course of the immunosuppressive agent cyclosporin A (CsA). Following cessation of CsA, this inducible disease is characterized by weight loss, diarrhea, and development of inflammation in the colon and liver. Although nonspecific effector cells and Th1 cytokines have been shown to participate in disease induction, the role of T cells has not been fully elucidated. Initial studies demonstrated significant increases in CD4+ T cells, but not other T cell populations in the colons of diseased animals relative to transplant control animals. To demonstrate a functional linkage between increases in colonic CD4+ T cells and disease induction, in vivo T cell depletion studies were performed. Beginning on the day of bone marrow transplantation, groups of control and CsA-treated animals were treated with mAb against either CD4 or CD8 for 21 days. Treatment with anti-CD4, but not anti-CD8, eliminated clinical symptoms and colon pathology. Interestingly, neither anti-CD4 nor anti-CD8 therapy affected the development of liver pathology associated with SGVHD. These findings demonstrated that CD4+ T cells initiate development of the intestinal inflammation associated with murine SGVHD.

Abstract
Although autologous graft-versus-host disease (GVHD) can be induced by administration of cyclosporin A (CsA) after peripheral blood stem cell transplantation (PBSCT), the incidence appears to be remarkably lower compared to the incidence after bone marrow transplantation. The reduced incidence of autologous GVHD after PBSCT may be attributed to peripheral regulatory cells that are transferred with the stem cell inoculum. To determine whether transplantation of CD34-selected peripheral blood stem cells (PBSCs) leads to potentiation of autologous GVHD, five patients with malignant lymphoma were transplanted with CD34-selected PBSCs, followed by administration of CsA and interferon (IFN)-gamma. Inducibility of autologous GVHD and autocytotoxic activities of peripheral blood mononuclear cells (PBMCs) after transplantation were assessed. All patients demonstrated prompt hematologic recovery. Cytotoxic activity of PBMCs against autologous lymphocytes was detectable in four of four patients analyzed during a limited period from days 14 to 34 post-transplant. An erythematous rash compatible with GVHD, confirmed by skin biopsy, developed in three of five patients. One of the three patients developed not only skin, but also gut and liver GVHD. Transplantation of the CD34-selected stem cell graft that does not accompany transfusion of regulatory cells may potentiate the inducibility of autologous GVHD by the administration of CsA and IFN-gamma.

Abstract
Administration of the immunosuppressive drug cyclosporine A (CsA) following autologous stem cell transplantation paradoxically elicits a systemic autoimmune syndrome resembling graft-versus-host disease (GVHD). This syndrome, termed autologous GVHD, is associated with autoreactive CD8(+) T cells that recognize major histocompatibility complex (MHC) class II determinants in association with a peptide from the invariant chain. To investigate the potential role of cytokines and chemokines in autologous GVHD, interleukin 2 (IL-2), IL-4, IL-10, interferon gamma (IFN-gamma), and macrophage inflammatory protein-1alpha (MIP-1alpha) gene expression in peripheral blood mononuclear cells (PBMCs) was determined in 36 patients treated with CsA following transplantation and correlated with the induction of cytolytic activity against autologous phytohemagglutinin-stimulated lymphocytes (PHA-blasts) and the breast cancer cell line (T47D). The determination of gene expression by real-time polymerase chain reaction (PCR) revealed that IL-10 mRNA levels by PBMCs in patients with autologous GVHD were 29-fold higher than in healthy individuals. IFN-gamma (4-fold), IL-2 (3-fold), and MIP-1alpha (44-fold) mRNA levels were also increased in GVHD-induced patients compared with healthy individuals. The ability of PBMCs to lyse autologous PHA-blasts and T47D tumor cells exhibited an identical temporal relationship with expression of IL-10 and IFN-gamma during autologous GVHD. Moreover, the susceptibility to autologous GVHD as assessed in 75 patients was significantly associated with the IL-10(-1082) G/G polymorphic alleles, allelic variants in the promoter region that govern IL-10 production. These findings indicate that IL-10 may play an unexpected but critical role in autologous GVHD and could be utilized to enhance a graft-versus-tumor effect after transplantation. Interestingly, polymorphisms in the IL-10 promoter region may also explain differences in the susceptibility of patients to autologous GVHD induction.

Abstract
An autoaggression graft-versus-host (GVHD)-like syndrome or engraftment syndrome (ES) presenting with skin rash, fever, and other clinical findings can accompany the early phase of engraftment after autologous peripheral blood stem cell (PBSC)/bone marrow (BM) transplantation. Because ES was suggested to be analogous to GVHD, we have investigated whether ES was associated with any graft-versus-tumor effect that would affect disease progression and survival in breast cancer patients. Eighty-five consecutive patients who received BM/PBSC transplantation for breast cancer (stages II-IV) between July 1991 and July 1997 with minimum 2-year follow-up were studied. Median follow-up time was 892 days (range, 106-2913 days). Thirty-three patients (39%) developed ES. The incidence of relapse/progressive disease for the whole cohort was 61% and was similar in patients who developed ES compared with those who did not. However, there was an increased rate of mortality observed among the patients who had developed ES versus those who had not, although it was statistically not significant, (52% versus 31%, respectively; log rank, P = .08). Increased mortality rates due to disease progression were seen in all patients with ES regardless of their disease stage. In relapsed patients, median survival time after transplantation was 586 days for those with ES versus 847 days for those without ES, and the mortality rate was 85% (17/20) versus 51% (16/31) (P = .008) for those with or without ES, respectively. Visceral (lung, liver, brain, adrenal) or multiple-site relapses were observed in 85% of patients with ES versus 52% without ES (P = .01). In conclusion, whereas there was no effect of ES on relapse rate, a surprisingly significant increase in disease-related mortality rates among relapsed breast cancer patients with ES was found. Thus, patients with ES should be considered for close follow-up and further therapy posttransplantation.

Abstract
Many hematologic disorders, leukemias and lymphomas in particular, can be cured with allogeneic hematopoietic stem cell transplantation (allo-SCT). However, chronic graft-versus-host disease (cGVHD) appears to remain as a major determinant of long term outcome and quality of life following allo-SCT. The gradual increase in the incidence of cGVHD over the past decade has recently gained another momentum along with the use of blood as a source of stem cells. Donor lymphocyte infusion (DLI) is also associated with a progressive form of cGVHD, mostly refractory to treatment. Prediction of the outcome of patients with newly diagnosed chronic GVHD may be important in identifying those who are likely to benefit from reduced treatment and patients who are unlikely to have a sustained response to standard treatment. In addition, a reliable predictive model could allow us to design better clinical trials and facilitate the communication among the centers. Although it is highly reproducible, the current system of grading in cGVHD is of limited utility since it does not stratify patients for outcome. It divides patients into those needing treatment (extensive cGVHD) and those who do not (limited cGVHD). Therefore, a new clinical grading system is needed to classify all patients based on their prognosis so like patients with similar features can be grouped for study and clinical management purposes. Using multivariate analysis, we recently identified three independent risk factors affecting the survival without recurrent malignancy. These factors are extensive skin involvement (>50% BSA), thrombocytopenia, and progressive-type onset of cGVHD. We are in the process of validating this prognostic model in three other cohorts from different institutions. We expect that the new grading system, based on this model, may allow us to identify the diversity of outcome within "extensive stage" cGVHD.

Abstract
Transfer of CD45RBhi CD4 + naïve T cells into severe combined immunodeficient (SCID) mice induces colitis and skin lesions. Recipients treated with cyclosporin A (CsA), CTLA4-Ig, or vehicle were evaluated for weight loss, skin lesions, and cutaneous blood flow. Necropsy, histological, hematological and cytokine analyses were performed at the conclusion of the experiment to confirm the clinical findings. Vehicle-treated mice lost weight and had 100% incidence of skin lesions by 46-days. CsA-treated mice also lost weight, but only 3/8 mice developed mild, clinically evident skin lesions. In contrast, all CTLA4-Ig-treated mice gained weight and did not develop skin lesions. Increase in cutaneous blood flow correlated with the development of skin lesions. Granulocyte numbers, which were high or moderately high in the vehicle- or CsA-treated mice, respectively, remained as low in the CTLA4-Ig-treated group as in untreated mice. IFN-gamma, IL-1beta, and TNF-alpha levels in the gut and skin correlated with the extent of inflammation in both organs. Histology revealed that CTLA4-Ig but not CsA effectively prevented both autoimmune disorders. The ability of CTLA4-Ig to prevent both colitis and skin lesions suggests that CD28-dependent co-stimulation of T cells is critical for generation of pro-inflammatory cytokines and induction of clinical disease in such autoimmune disorders.

Abstract
The N-terminal flanking region of the invariant chain peptide termed CLIP appears to have superagonistic properties interacting with the T cell receptor and the MHC class II molecule at or near the binding site for the bacterial superantigen Staphylococcal enterotoxin B (SEB). The present studies explored the hypothesis that the N-terminal segment of CLIP can augment the immunogenicity of cryptic "self" tumor-associated antigens. A chimeric construct of an MHC class II binding peptide from the c-erb oncogene (Her-2/neu) containing the N-terminal flanking region of CLIP elicited potent antitumor activity against a Her-2/neu-positive tumor in a rat model system. Comparatively, the unmodified parent peptide was ineffective. The induction of effective antitumor immunity, however, required presentation of the chimeric peptide construct on irradiated tumor cells or the peptide construct in concert with a Her-2/neu MHC class I-restricted peptide from Her-2/neu. As revealed by adoptive transfer studies, effective protective antitumor immunity in this setting required the CD4 T helper subset. Additionally, in vitro analysis revealed that immunization with the parent peptide resulted in a weak immune response to the unmodified peptide consisting of both type 1 (IL-2, IFN-gamma) and type 2 (IL-4, IL-10) cytokine-producing cells analyzed by RT-PCR (qualitative and quantitative) and by limiting dilution assay. Comparatively, immunization with the chimeric construct elicited a potent immune response to the parent peptide with predominantly type 1 cytokine-producing cells. Taken together, the results suggest that immunization with the chimeric Her-2/neu peptide induced protective antitumor immunity. Associated with this immunization strategy was the enhancement of a type 1 cytokine response.

Abstract
Autologous bone marrow transplantation and autologous peripheral blood stem cell transplantation (APBSCT) are alternative therapeutic options in the treatment of various malignancies. We describe four patients undergoing APBSCT for malignancies; they developed a cutaneous eruption characterized by confluent erythematous and hyperpigmented patches within the flexural areas during the first month after transplantation. The lesions were poorly circumscribed without epidermal changes such as scaling, xerosis, erosions or atrophy. The skin patches were treated with topical corticosteroids and resolved within a few days with discoloration. Histopathological findings were characterized by focal vacuolar degeneration of the basal layer with epidermal dysmaturation. We believe that these cutaneous eruptions are consistent with an interplay of high-dose chemotherapy and local factors such as friction, local skin temperature and eccrine gland distribution, which could explain the constant location of this eruption in the axillae and genital area.

Abstract
Administration of cyclosporine A (CsA) after autologous stem cell transplantation elicits an autoimmune syndrome with pathology similar to graft-versus-host disease (GVHD). This syndrome, termed autologous GVHD, is associated with the appearance of autoreactive T cells directed at major histocompatibility class (MHC) class II antigens. In the rat model of autologous GVHD, clonal analysis reveals that the effector T cells are highly conserved and recognize a peptide from the invariant chain peptide presented by MHC class II. Although human autologous GVHD effector T cells share a similar phenotypic specificity, clonality of the response in humans has not been determined. To examine the human effector T-cell response, the T-cell repertoire of peripheral blood lymphocytes was assessed by complementarity-determining region 3 (CDR3) size distribution analysis and T-cell clonotype analysis in 26 patients treated with CsA after transplantation. Autologous GVHD developed in 3 of 4 patients with human leukocyte antigen (HLA)-DRB1*0701, and clonal expansions of beta-chain variable region (BV)16(+) T cells were shared. Clonal expansions within BV15(+) and BV22(+) T cells were also detected in 4 of 6 patients with HLA-DRB1*1501 and in 3 of 4 patients with HLA-DRB1*0401, respectively. Sequencing of BV16 cDNA for which the CDR3 size pattern exhibited apparent clone predominance revealed an identical CDR3 peptide sequence in 2 different patients, one with HLA-DRB1*0701 and the other with HLA-DRB1*1502. These findings indicate that the discrete antigen-driven expansion of T cells is involved in autologous GVHD. (Blood. 2001;98:868-876)

Abstract
The use of the immunosuppressive drug cyclosporine A (CsA) in solid organ transplantation can be associated with the development of vasculopathy as part of the complex immune response involved in chronic rejection, including autoimmune recognition. Although CsA can directly affect endothelial cells, this drug alters the T cell repertoire promoting autoimmune recognition. The present studies evaluated the ability of CsA-induced autoreactive T cells to mediate vascular lesions in syngeneic heart grafts. Graft vasculopathy developed in syngeneic heart grafts following either the primary induction of autoimmunity with CsA or the adoptive transfer of CsA-induced autoreactive T cells. Initially, an inflammatory response occurred in the medial wall of the small arterial vessels, accompanied by a perivascular lymphocytic infiltrate (including a lymphocytic infiltrate into the myocardium), followed by progression of vascular disease with endothelial cell proliferation. The development and progression of vascular disease correlated with the cytokine profile of the infiltrating lymphocytes with type 1 cytokines detected early and type 2 cytokines detected as the disease progressed. Initiation of this response correlated with upregulation of the target antigen recognized by the CsA-induced autoreactive T cells, the MHC class II-invariant chain peptide complex. This antigen complex, when upregulated on endothelial cells by interferon, allowed effective targeting by the autoreactive T lymphocytes. Strategies to inhibit the upregulation of MHC class II antigens by treatment of the recipients with chloroquine truncated the disease process. The results of these studies suggest that CsA-induced autoreactive mechanisms can contribute to the development of graft vasculopathy.

Abstract
Acute and chronic GvHD are still a major concern in allogeneic hematopoietic stem cell transplantation, still contributing substantially to morbidity and mortality in this therapeutic procedure. Over the past decade, many advances have been made with regard to the prevention and treatment of GvHD using various drugs such as cyclosporine A, FK506, mycophenolate mofetil and/or monoclonal IL-2 receptor antagonists. Despite these measurements with regard to the prevention of acute GvHD, it is very difficult to treat these clinical conditions successfully. However, if patients do not experience any GvHD often the desired effect of graft versus leukemia (GvL) remains absent increasing the probability of a relapse, in particular, in patients transplanted, which are considered at higher risk for relapse. At the present time, new strategies in the prevention of acute GvHD are in progress in particular the use of genetic manipulated donor T cells expressing suicide genes. Further clinical and laboratory studies are required in order to improve the prevention and, in particular, the therapy of established GvHD.

Abstract
Pulmonary inflammation is one of the risk factors associated with blood and marrow transplantation (BMT). To determine the potential role of T cells in pulmonary complications after transplantation, we analyzed the T-cell repertoire expressed in bronchoalveolar lavage fluids from eleven patients with graft-versus-host disease following BMT. A reverse transcriptase-polymerase chain reaction was used to amplify rearranged TCR transcripts in unfractionated, CD4+, and CD8+ T cells from bronchoalveolar lavage fluids. The relative expression of TCR variable (V) gene families and the diversity of junctional region lengths associated with different AV and BV gene families were analyzed. Nearly all TCR AV and BV gene families were detected in bronchoalveolar lavage cells from BMT recipients. Oligoclonal patterns of TCR junctional region lengths were observed in unfractionated, CD4+, and CD8+ bronchoalveolar T cells. The oligoclonal expansion of bronchoalveolar T cells in patients was confirmed by DNA sequencing. TCRV gene expression is almost completely restored in the lungs of BMT recipients as early as two weeks after transplantation. Increased oligoclonality among TCR gene families suggests either an incomplete restoration of TCR diversity or an antigen-driven expansion of T cells in the lungs of BMT recipients with graft-versus-host disease, not necessarily related to pulmonary infection.

Abstract
T cells mediate various autoimmune diseases. Pathologic autoimmunity can be induced by manipulating thymic or peripheral control of self-reactive T cells. There is, for example, accumulating evidence that elimination or dysfunction of regulatory T cells can elicit T cell mediated, destructive autoimmune disease in otherwise normal animals and enhance autoimmunity in spontaneous models.

Abstract
BACKGROUND The role of major histocompatibility complex class II antigens in hematopoiesis is not well defined. We have shown that in vitro depletion of HLA-DR+ cells from canine marrow (e.g., by anti-HLA-DR monoclonal antibody [mAb] H81.9 and complement) prevents hematopoietic recovery. In vivo administration of the same mAb H81.9 after transplantation of unmanipulated autologous marrow results in graft failure. In vitro mAb H81.9 inhibited colony formation from short-term and long-term marrow cultures. METHODS AND RESULTS We investigated the effect of another mAb, Ca1.41, which also recognizes nonpolymorphic determinants on human (HLA-DR) and canine major histocompatibility complex class II antigens but is reactive with a narrower spectrum of cells in both canine peripheral blood and marrow than mAb H81.9 (and other anti-HLA-DR mAbs). In contrast to all other anti-HLA-DR mAbs tested, Ca1.41 did not interfere with colony formation in short-term or long-term marrow cultures and spared a population of small mononuclear cells with low forward light scatter that was eliminated via apoptosis by exposure to mAb H81.9. These target cells included lymphocytes and CD34+ hemopoietic precursors that expressed MHC class II molecules as determined by mAb H81.9 but not by mAb Ca1.41. In addition, transmembrane signaling and up-regulation of interleukin-1beta mRNA occurred with mAb H81.9 but not with Ca1.41. Transplantation of autologous marrow treated in vitro cytolytically with mAb Ca1.41 allowed for complete hematopoietic reconstitution. Further, in vivo administration of Ca1.41 posttransplant did not lead to autologous graft failure as had been observed with mAb H81.9. CONCLUSIONS These results support the notion that major histocompatibility complex class II is expressed on early hematopoietic precursor cells but recognition is dependent upon the mAb used. Preliminary studies show that mAb H81.9 triggered transmembrane signaling, resulting in up-regulation of interleukin-1beta and apoptosis, although mAb Ca1.41 did not. The fact that Ca1.41 binding was modified in the presence of exogenous invariant chain-derived peptide suggests that both binding and signaling are peptide dependent.

Abstract
Abstract
Syngeneic graft-vs-host disease (SGVHD) is induced by reconstituting lethally irradiated mice with syngeneic bone marrow cells followed by a short course of therapy with the immunosuppressive agent cyclosporine A. Following cessation of cyclosporine A therapy, animals develop clinical symptoms of SGVHD: weight loss, runting, and diarrhea. While it has been suggested that T cells are responsible for the induction and effector phases of SGVHD, the role of nonspecific effector cells and cytokine mediators has yet to be examined in the disease process. Mice with SGVHD had increased levels of message for IL-12p40, IFN-γ, and TNF-α in the target organs of SGVHD as compared with transplant controls and asymptomatic cyclosporine A-treated mice. Concomitant with the increase in Th1 cytokines was an enhanced cellular infiltrate in the target organs of SGVHD mice as determined by histological analysis. To directly examine the role of IL-12 in the development of SGVHD, in vivo neutralization of IL-12 was performed. Treatment of mice with Abs to IL-12 inhibited SGVHD-mediated tissue pathology and mortality. Because IL-12 has been shown to activate both T cells and NK cells to secrete IFN-γ and to become more cytolytic, studies were initiated to ascertain which lymphocyte populations play a role in the development of murine SGVHD. Depletion of NK cells inhibited clinical symptoms of SGVHD. In contrast, T cell depletion did not alter the disease process. Therefore, these findings collectively demonstrate a role for IL-12 and NK cells in the effector phase of murine SGVHD.

Abstract
Abstract
Administration of the immunosuppressive drug cyclosporine after syngeneic bone marrow transplantation paradoxically elicits a systemic autoimmune syndrome resembling graft-vs-host disease (GVHD). This syndrome, termed syngeneic GVHD, is associated with the development of CD8+ cytolytic T lymphocytes that promiscuously recognize MHC class II molecules in association with a peptide from the invariant chain (CLIP). Clonal analysis reveals a major subset of cells that are pathogenic and require the N-terminal flanking region of CLIP for activation, while there is a minor subset of nonpathogenic T cells that require the C-terminal flanking region. The present studies show that pathogenic T cells produce type 1 cytokines (IL-2; IFN-γ), while the nonpathogenic clones produce type 2 cytokines (IL-4; IL-10). Moreover, the repertoire of the pathogenic T cells is highly conserved with respect to Vβ and Vα TCR gene expression. The vast majority of clones express Vβ8.5 (12/12) and Vα11 (11/12). Although a limited number was evaluated, the nonpathogenic clones have only a Vα restriction. Sequence analysis of the pathogenic T cell clones reveals a marked heterogeneity in the complementarity-determining region 3 domain and differential J region gene expression for both TCR α- and β-chains. Evaluation of the specificity of these clones suggests that the functional interaction between the N-terminal flanking region of CLIP (defined by the amino acid sequence -KPVSP-) and the V region of the TCR is critical, allowing effective target cell recognition and tissue destruction in syngeneic GVHD.

Abstract
Hodgkin's disease is a common malignancy of the lymphoid system. Although the scarce Hodgkin and Reed-Sternberg (HRS) tumor cells in involved tissue synthesize major histocompatibility complex (MHC) class II and costimulatory molecules such as CD40 or CD86, it is unclear whether these tumor cells are operational antigen-presenting cells (APC). We developed an immunofluorescence-based assay to determine the number of MHC class II molecules present on the surface of single living HRS cells. We found that in fresh Hodgkin's disease lymph node biopsies, a subset of HRS cells express a substantial number of surface MHC class II molecules that are occupied by MHC class II–associated invariant chain peptides (CLIP), indicating deficient loading of MHC class II molecules with antigenic peptides. Cultured Hodgkin's disease–derived (HD) cell lines, however, were found to express few MHC class II molecules carrying CLIP peptides on the cell surface and were shown to generate sodium dodecyl sulphate (SDS)-stable MHC class II αβ dimers. In addition to showing deficient MHC class II antigen presentation in a subset of HRS cells, our results show that the widely used HD-cell lines are not ideal in vitro models for the disease. The disruption of MHC class II–restricted antigen presentation in HRS cells could represent a key mechanism by which these tumor cells escape immune surveillance.
