Abstract
Graft-versus-host disease (GVHD) is a serious complication of hematopoietic stem cell transplantation. The main clinical targets of GVHD are the skin, liver, gastrointestinal tract, and possibly the lung. The standard initial therapy for GVHD includes the use of high-dose steroids, which result in an unsatisfactory complete response (CR) rate of about 40% and the need to develop more effective therapies. The Clinical Trial Network is conducting a four-arm randomized phase II study evaluating prednisone in combination with one of the following four agents: etanercept, mycophenolate mofetil, denileukin diftitox, and pentostatin. Etanercept, an anti-TNF-alpha antibody, is also being evaluated in combination with steroids in a single-center phase II trial at the University of Michigan because of the role of TNF-alpha in the pathogenesis of GVHD. TNF-alpha and a surrogate marker, soluble TNF receptor, are elevated in patients with GVHD as early as 7 days after transplantation and maybe used in the future as a prognostic tool to identify transplant recipients at risk for developing GVHD.

Abstract
More than 40000 hematopoietic cell transplants (HCTs) are performed worldwide each year. With improvements in transplant technology, larger numbers of transplant recipients survive free of the disease for which they were transplanted. However, there are late complications that can cause substantial morbidity. Many survivors are no longer under the care of transplant centers, and many community health care providers may be unfamiliar with health matters relevant to HCT. The Center for International Blood and Marrow Transplant Research (CIBMTR), European Group for Blood and Marrow Transplantation (EBMT), and American Society for Bone Marrow Transplantation (ASBMT) have developed these recommendations to offer care providers suggested screening and prevention practices for autologous and allogeneic HCT survivors.

Abstract
The First International Symposium on Photopheresis in Hematopoietic Stem Cell Transplantation was held in Vienna, Austria with an educational grant from Therakos Inc. from 25 May to 27 May 2005. Three general issues were addressed: (1) pathophysiology of graft-versus-host disease (GvHD), (2) induction of immune tolerance and the immunology of phototherapy and (3) current standard treatment and prevention strategies of acute and chronic GvHD and the use of extracorporeal photopheresis (ECP). The objectives of the meeting were to open a dialogue among leading researchers in photobiology, immunology, and hematopoietic stem cell transplantation; foster discussions and suggestions for future studies of the mechanism of action of ECP in acute and chronic GvHD; and promote collaboration between basic scientists and clinicians. As can be seen from the summaries of the individual presentations, important advances have been made in our understanding of GvHD, including the use of photoimmunology interventions and the development of robust model systems. It is our expectation that data from photoimmunology studies can be used to generate hypotheses in animal models that can further define the mechanism of action of ECP and help translate the findings to clinical trials of ECP for the prophylaxis and treatment of both chronic and acute GvHD.

Abstract
Palifermin, a recombinant human keratinocyte growth factor, was tested for potential benefits on acute graft-versus-host disease (GVHD) and hematopoietic recovery in allogeneic hematopoietic stem cell transplantation (HSCT) recipients. This randomized, double-blind, placebo-controlled, dose-escalation study assessed the safety and tolerability of palifermin (n = 69) as compared with placebo (n = 31) in patients conditioned with cyclophosphamide and fractionated total-body irradiation (Cy/TBI) or busulfan and cyclophosphamide (Bu/Cy) and given methotrexate along with a calcineurin inhibitor (cyclosporine A, tacrolimus) for GVHD prophylaxis. All patients received 3 doses before conditioning and either 3 (cohort 1), 6 (cohort 2), or 9 (cohort 3) doses after HSCT. Palifermin doses were 40 mug/kg per day (cohort 1 only) or 60 mug/kg per day (all cohorts). Six patients (placebo = 2, palifermin = 4) experienced a total of 11 dose-limiting toxicities (most often skin, respiratory, or oral mucositis). The most common adverse events included edema, infection, skin pain, or rash. Times to neutrophil and platelet engraftment were similar. No significant differences in acute GVHD incidence or severity, survival, or day 100 relapse rates were observed between groups. Palifermin was associated with reduced incidence and mean severity of mucositis in patients conditioned with Cy/TBI but not Bu/Cy. We conclude that palifermin was generally safe in allogeneic HSCTs but had no significant effect on engraftment, acute GVHD, or survival in this trial.

Abstract
Complications of allogeneic hematopoietic stem cell transplantation (HSCT) remain barriers to its wider application for a variety of diseases. Graft-versus-host disease (GVHD) is the major cause of morbidity and mortality following allogeneic HSCT. GVHD can be considered an exaggerated, undesirable manifestation of a normal inflammatory mechanism, in which donor lymphocytes encounter foreign antigens in a milieu that fosters inflammation. Recent advances in the study of cytokine networks, chemokine gradients, and the direct mediators of cellular cytotoxicity have led to improved understanding of this complex syndrome. The pathophysiology of acute GVHD can be considered as a three-step process in which the innate and adaptive immune systems interact: (1) tissue damage to the recipient by the radiation/chemotherapy pretransplant conditioning regimen; (2) donor T-cell activation and clonal expansion; and (3) cellular and inflammatory factors. Here we review the immunologic interactions that cause clinical GVHD and discuss the risk factors and prophylactic strategies for acute GVHD according to this model.

Abstract
Dendritic cells (DCs) derive from CD34+ cells or monocytes and stimulate alloimmune responses in transplantation. We hypothesized that the interaction between CD34+ cells and allogeneic T cells would influence the function of hematopoietic stem cells (HSCs). Cord blood (CB) CD34+ cells proliferated briskly in response to allogeneic, but not autologous, T cells when mixed with irradiated T cells for 6 days in vitro. This proliferation was significantly inhibited by an anti-HLA class II monoclonal antibody (mAb), by an anti-TNFalpha mAb, or by CTLA4-Ig. Allogeneic T cells induced the differentiation of CD34+ progenitors into cells with the morphology of dendritic monocytic precursors and characterized by the expression of HLA-DR, CD86, CD40, CD14, and CD11c, due to an endogenous release of TNFalpha. Cotransplantation of CD34+ cells with allogeneic T cells into nonobese diabetic-severe combined immunodeficiency (NOD/SCID) mice resulted in a greater engraftment of myeloid CD1c+ dendritic cells compared with cotransplantation with autologous T cells. In vitro, CD34+ cell-derived antigen-presenting cells (APCs) were functionally capable of both direct and indirect presentation of alloantigens. Based on these findings, we hypothesize that in HSC transplantation the initial cross talk between allogeneic T cells and CD34+ cells may result in the increased generation of APCs that can present host alloantigens and possibly contribute to the development of graft-versus-host disease.

Abstract
Hepatic dysfunction following hematopoietic stem cell transplantation (HSCT) is common, but making the correct diagnosis can be challenging. Liver biopsies can serve as an important diagnostic tool when the etiology cannot be clearly determined by laboratory data, physical examination, and imaging studies. We reviewed 12 consecutive pediatric patients (seven males, five females, age 9-23 years) who received allogeneic HSCT and underwent a laparoscopic-guided liver biopsy for hepatic dysfunction of unknown etiology from 1998 to 2005. Biopsies were performed using a single-port technique with a 16 or 18 gauge, spring-loaded biopsy gun. The time from HSCT to biopsy ranged from 31 days to 821 days (median 92 days). No intra- or postoperative complications were observed. The initial clinical diagnosis was confirmed in seven patients, whereas the initial working diagnosis was inaccurate in the remaining five patients. Our results suggest that laparoscopic-guided liver biopsy is an informative and safe procedure in pediatric HSCT recipients; this approach helped delineate the true cause of hepatic dysfunction and changed our therapeutic approach in approximately 40% of the patients reviewed. While the safety record at our institution appears promising, a larger multi-institutional study would be necessary to more accurately describe the overall efficacy of this procedure in pediatric HSCT patients.

Abstract
Clinical and preclinical data indicate that tumor necrosis factor (TNF)-alpha is an important mediator of acute graft-versus-host disease (aGVHD) after allogeneic bone marrow transplantation. We completed a study using etanercept, a fusion protein capable of neutralizing TNF-alpha, for the initial treatment of aGVHD. Etanercept (25 mg subcutaneously) was administered twice weekly for 16 doses, along with methylprednisolone (2 mg/kg) and tacrolimus for biopsy-proven aGVHD. Twenty patients with a median age of 47 years (range, 8-63 years) were enrolled. Fourteen patients with grade II aGVHD (11 family donors and 3 unrelated donors) and 6 patients with grade III aGVHD (3 family donors and 3 unrelated donors) were treated. Twelve patients completed 16 doses of therapy, and 8 received 5 to 15 doses. Reasons for not completing all doses of etanercept included progression of aGVHD (n = 4), relapsed leukemia (n = 2), progression of pulmonary and central nervous system lesions (n = 1), and perforated duodenal ulcer (n = 1). Fifteen (75%) of 20 patients had complete resolution of aGVHD within 4 weeks of therapy. Increasing levels of soluble TNF receptor 1 plasma concentration during the first 4 weeks of therapy indicated progression of aGVHD in 5 patients. In contrast, for 15 responding patients, soluble TNF receptor 1 plasma concentration levels returned to baseline. These data demonstrate the feasibility of using cytokine blockade in the early treatment of aGVHD.

Abstract
Graft-versus-leukemia (GVL) response after allogeneic bone marrow transplantation (BMT) represents one of the most potent forms of immunotherapy against malignant diseases. Antigen-presenting cells (APCs) are crucial for the induction of graft-versus-host disease (GVHD), the most serious complication of allogeneic BMT, but their role in GVL responses is unclear. Using a series of clinically relevant mouse GVL tumor models, we found that APCs and alloantigen expression on tumors are crucial for GVL. Moreover, APCs of host origin predominated in GVL responses although donor APCs contributed as the acuity of tumor burden decreased.

Abstract
PURPOSE To describe lacrimal gland involvement in a murine model of acute graft-versus-host disease (GVHD). METHODS Histopathologic examination was performed on lacrimal glands of mice affected by GVHD at 1, 2, 4, and 6 weeks after allogeneic bone marrow transplantation (BMT). Histopathologic scoring, based on characteristic GVHD findings in human disease involved evaluation of periductal inflammation, apoptosis, ductal stasis, ductal debris, and fibrosis. CD3, CD4, CD8, CD20, and CD68 antibodies were used to stain leukocyte subsets in GVHD lacrimal gland infiltrates. Lacrimal glands from syngeneic BMT mice were used in control experiments. RESULTS Patchy periductal inflammation and focal fibrosis were significantly elevated as early as 2 weeks after allogeneic BMT. Histopathologic scoring of lacrimal glands after allogeneic BMT was significantly different at 4 (P = 0.005) and 6 (P < 0.0001) weeks when compared with scores in syngeneic control mice. The leukocytes in lacrimal gland GVHD infiltrates were predominately CD3+ T lymphocytes, most of which were CD8+, with fewer CD4+ cells present. CONCLUSIONS This study describes the first murine model of lacrimal gland GVHD with features that closely mimic those described in human disease and indicates that lacrimal involvement occurs in acute GVHD.

Abstract
Gammadelta T cells localize to target tissues of graft-versus-host disease (GVHD) and therefore we investigated the role of host gammadelta T cells in the pathogenesis of acute GVHD in several well-characterized allogeneic bone marrow transplantation (BMT) models. Depletion of host gammadelta T cells in wild-type (wt) B6 recipients by administration of anti-T-cell receptor (TCR) gammadelta monoclonal antibody reduced GVHD, and gammadelta T-cell-deficient (gammadelta-/-) BM transplant recipients experienced markedly improved survival compared with normal controls (63% vs 10%, P < .001). gammadelta T cells were responsible for this difference because reconstitution of gammadelta-/- recipients with gammadelta T cells restored GVHD mortality. gammadelta-/- recipients showed decreased serum levels of tumor necrosis factor alpha (TNF-alpha), less GVHD histopathologic damage, and reduced donor T-cell expansion. Mechanistic analysis of this phenomenon demonstrated that dendritic cells (DCs) from gammadelta-/- recipients exhibited less allostimulatory capacity compared to wt DCs after irradiation. Normal DCs derived from BM caused greater allogeneic T-cell proliferation when cocultured with gammadelta T cells than DCs cocultured with medium alone. This enhancement did not depend on interferon gamma (IFN-gamma), TNF-alpha, or CD40 ligand but did depend on cell-to-cell contact. These data demonstrated that the host gammadelta T cells exacerbate GVHD by enhancing the allostimulatory capacity of host antigen-presenting cells.

Abstract
Reduced-intensity stem cell transplantation (RIST) has been shown to be a safe and useful alternative transplant method for patients including elderly and medically unfit patients. RIST conditioning regimens vary widely in the intensity of myeloablation, immunoablation, and antileukemia effects, and thus optimal regimen for each disease entity is yet to be determined. Most reports on RIST to date are small, single-institution experiences or retrospective studies with heterogeneous patient populations and primary diseases, complicating any direct comparison between studies. In acute myeloid leukemia (AML), moderate-intensity regimens may be effective, achieving 30-70% 1-year disease-free survival in various series, but minimal-intensity regimens are associated with high relapse rates. In acute lymphoblastic leukemia (ALL), not even moderate-intensity regimens are effective and most patients with advanced ALL relapse post transplant. Thus, the risk/benefit ratios of graft-versus-host disease/graft-versus-leukemia effect differ among diseases. Larger, prospective, multi-center clinical trials are needed to determine the best use of RIST in hematologic malignancies.

Abstract
PURPOSE With improvements in breast imaging and image-guided interventions, there is interest in ablative techniques for breast cancer. Cryosurgery initiates inflammation and leaves tumor-specific antigens intact, which may induce an anti-tumor immune response. To help define the mechanisms involved in the cryoimmunologic response, we compared cryosurgery to surgery in a murine model of breast cancer. EXPERIMENTAL DESIGN BALB/c mice with MT-901 tumors underwent cryoablation or resection. Mice successfully treated were re-challenged with MT-901 or RENCA. Serum cytokine levels were analyzed by ELISA. Tumor draining lymph nodes (TDLN) and spleens were harvested, lymphocytes were activated and assessed for a specific anti-tumor response by both an interferon-gamma (IFNgamma) release assay and ELISPOT. NK cell activity was assessed by cytotoxicity against YAC-1, an NK-susceptible cell line. RESULTS After re-challenge, tumors developed in 86% of mice treated by surgical excision compared to 16% of mice treated by cryosurgery (p=0.025). Cryoablation of MT-901 had no effect on re-challenge with RENCA. Cryoablation led to significantly higher levels of interleukin (IL)-12 (383.6 pg/ml +/- 32.8 versus 251.6 +/- 16.5, p=0.025) and IFN-gamma (1564 pg/ml +/- 49 versus 1244 pg/ml +/- 101, p=0.009), but no changes in IL-4 or IL-10. Tumor-specific T-cell responses were evident after cryosurgery in lymphocytes from TDLN but not from spleen. Cryoablation also increased NK activity compared to surgery (24.5% +/- 17.3 versus 16.5% +/- 5.9, p < 0.001). CONCLUSION Cryoablation results in the induction of both a tumor-specific T-cell response in the TDLN and increased systemic NK cell activity, which correlates with rejection of tumors upon re-challenge.

Abstract
Defects in immune reconstitution after hematopoietic stem cell transplantation confer extreme infection risk on to the transplant recipient. Perturbations in adaptive immune reconstitution have been well characterized, yet defects in reconstituted innate cellular-mediated immunity remain largely unstudied. Recovery in innate effector cells was defined by using an established murine model of autologous bone marrow transplantation. Cytokine induction after cell culture and systemic stimulation with pathogen-associated molecular patterns was also measured for control, transplant-recipient, and irradiated-only animals. Early reconstitution (7 to 14 days) of donor-derived macrophages, dendritic cells, and polymorphonuclear cells was associated with recovery in interleukin (IL)-12p70 and IL-6 production. Later reconstitution (21 days) of natural killer cells was associated with interferon (IFN)-gamma recovery. Hence, splenocyte innate cellular-mediated immunity recovered to normal levels in cellularity and IL-12p70, IFN-gamma, and IFN-alpha production by 21 days after transplantation. In contrast, levels of systemic cytokine production from transplant-recipient and irradiated-only animals were preserved despite incomplete or absent hematopoietic reconstitution. These results suggest that innate immune responses to systemic inflammatory challenges are largely intact after autologous bone marrow transplantation, whereas local innate cellular-mediated immunity within reconstituting lymphoid organs may be impaired. The disparate effects of autologous hematopoietic stem cell transplantation on host immune function may translate to differences in susceptibility to local versus systemic infectious challenges.

Abstract
Acute graft versus host disease (GVHD) remains the greatest complication of allogeneic bone marrow transplantation and a major cause of morbidity and mortality. This article summarizes the risk factors and prevention strategies for acute GVHD by considering them within the context of disease pathophysiology. Acute GVHD can be considered a 3-step process: 1) damage from chemotherapy/radiotherapy; 2) host antigen-presenting cell activation and amplification of donor T cells; and 3) target cell apoptosis via cellular and inflammatory mediators. This conceptual framework helps to explain the effectiveness of current prevention strategies and points to areas where new drugs and approaches may be of clinical benefit.

Abstract
The initiation of graft-vs-host disease (GVHD) after stem cell transplantation is dependent on direct Ag presentation by host APCs, whereas the effect of donor APC populations is unclear. We studied the role of indirect Ag presentation in allogenic T cell responses by adding populations of cytokine-expanded donor APC to hemopoietic grafts that would otherwise induce lethal GVHD. Progenipoietin-1 (a synthetic G-CSF/Flt-3 ligand molecule) and G-CSF expanded myeloid dendritic cells (DC), plasmacytoid DC, and a novel granulocyte-monocyte precursor population (GM) that differentiate into class II+,CD80/CD86+,CD40- APC during GVHD. Whereas addition of plasmacytoid and myeloid donor DC augmented GVHD, GM cells promoted transplant tolerance by MHC class II-restricted generation of IL-10-secreting, Ag-specific regulatory T cells. Importantly, although GM cells abrogated GVHD, graft-vs-leukemia effects were preserved. Thus, a population of cytokine-expanded GM precursors function as regulatory APCs, suggesting that G-CSF derivatives may have application in disorders characterized by a loss of self-tolerance.

Abstract
The substantial complexity and vast dynamic range of protein abundance in biological fluids, notably serum and plasma, present a formidable challenge for comprehensive protein analysis. Integration of multiple technologies is required to achieve high-resolution and high-sensitivity proteomics analysis of biological fluids. We have implemented an orthogonal three-dimensional intact-protein analysis system (IPAS), coupled with protein tagging and immunodepletion of abundant proteins, to quantitatively profile the human plasma proteome. Following immunodepletion, plasma proteins in each of paired samples are concentrated and labeled with a different Cy dye, before mixing. Proteins are subsequently separated in three dimensions according to their charge, hydrophobicity, and molecular mass. Differences in the abundance of resolved proteins are determined based on Cy dye ratios. We have applied this strategy to profile the plasma proteome for changes that occur with acute graft-versus-host disease (GVHD), following allogeneic bone marrow transplantation (BMT). Using capillary HPLC ESI Q-TOF MS, we identified 75 proteins in the micromolar to femtomolar range that exhibited quantitative differences between the pre- and post-GVHD samples. These proteins included serum amyloid A, apolipoproteins A-I/A-IV, and complement C3 that are well-known acute-phase reactants likely reflecting the post-BMT inflammatory state. In addition, we identified some potentially interesting immunologically relevant molecules including vitamin D-binding protein, fetuin, vitronectin, proline-rich protein 3 and 4, integrin-alpha, and leukocyte antigen CD97. IPAS provides a combination of comprehensive profiling and quantitative analysis, with a substantial dynamic range, for disease-related applications.

Abstract
Severe congenital neutropenia (SCN) is a hematologic condition characterized by arrested maturation of myelopoiesis at the promyelocyte stage of development. With appropriate treatment using recombinant human granulocyte-colony-stimulating factor (r-HuG-CSF), SCN patients are now surviving longer, but are at increased risk of developing myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML). Hematopoietic stem cell transplantation (HSCT) is the only curative option for these patients, but transplantation outcomes after malignant transformation are not well established. We report results for six patients with SCN who underwent HSCT for MDS or AML between 1997 and 2001 at two transplant centers. Two patients transplanted for MDS survived. Both of these patients were transplanted without being given induction chemotherapy. Four patients, who all received induction chemotherapy for AML prior to HSCT, died. Administering induction chemotherapy prior to HSCT resulted in significant morbidity. Rapid transplantation should be the goal for the SCN patient once the diagnosis of MDS/AML is established. SCN patients should be monitored carefully for progression to MDS in order to be treated with HSCT as soon as they have progressed and before developing AML. For SCN patients who progress to AML, HSCT should still be considered, even though the risks appear to be greater.

Abstract
Despite impressive advances in the field of allogeneic hematopoietic transplantation, graft versus host disease (GVHD) remains a significant obstacle to be overcome; it would enhance the safety and efficacy of this life-saving therapy. This review provides a framework for understanding the molecular and cellular basis underlying GVHD. We propose a 3-phase model of GVHD that highlights the importance of the conditioning regimen on the recipient tissues administered prior to infusion of donor bone marrow inoculum. A novel skin explant model, designed to take into consideration the immunobiological consequences of conditioning regimens on resident host cells, is proposed to advance our understanding of GVHD and serve as a potential prognostic tool when allogeneic recipient/donor combinations are being contemplated in the clinic. Within this review, specific emphasis is placed on the importance of defining the apoptotic machinery engaged in epidermal keratinocytes triggered by both conditioning regimens, and by host resident and recruited immunocytes and soluble mediators produced at sites of injury. The review is completed with a working model for cutaneous GVHD. Although the skin is highlighted because of its accessibility for clinical observations and serial sampling opportunities, lessons learned from studies of cutaneous GVHD are likely to provide valuable insights into GVHD occurring in the gastrointestinal tract, lung, and liver. With new insights designed to better predict and prevent GVHD and novel agents designed to treat GVHD, overcoming this current impediment to successful bone marrow transplantation should become increasingly feasible.

Abstract
The use of granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral blood as a source of stem cells has resulted in a high incidence of severe chronic graft-versus-host disease (cGVHD), which compromises the outcome of clinical allogeneic stem cell transplantation. We have studied the effect of G-CSF on both immune complex and fibrotic cGVHD directed to major (DBA/2 --> B6D2F1) or minor (B10.D2 --> BALB/c) histocompatibility antigens. In both models, donor pretreatment with G-CSF reduced cGVHD mortality in association with type 2 differentiation. However, after escalation of the donor T-cell dose, scleroderma occurred in 90% of the recipients of grafts from G-CSF-treated donors. In contrast, only 11% of the recipients of control grafts developed scleroderma, and the severity of hepatic cGVHD was also reduced. Mixing studies confirmed that in the presence of high donor T-cell doses, the severity of scleroderma was determined by the non-T-cell fraction of grafts from G-CSF-treated donors. These data confirm that the induction of cGVHD after donor treatment with G-CSF is dependent on the transfer of large numbers of donor T cells in conjunction with a putatively expanded myeloid lineage, providing a further rationale for the limitation of cell dose in allogeneic stem cell transplantation.

Abstract
Results obtained in recent experiments suggest that bone marrow-derived cells (BMDCs) engraft into tissues and differentiate into various somatic cell types. However, it is unclear whether injury is required for the phenomenon to occur at appreciable frequencies. In this study we tested whether BMDCs engraft into kidneys and differentiate into renal cells in the absence or presence of toxic injury. Renal damage was induced by delivery of folic acid (FA) to bone marrow (BM)-recipient mice 1 or 9 months after bone marrow transplant, and kidneys were examined for donor-derived cells 2,4, or 8 weeks after injury. Donor-derived cells were abundant in the renal interstitium of injured kidneys and were detected in glomeruli of vehicle- and FA-treated mice. Most of these cells expressed the common leukocyte antigen CD45 and display morphological characteristics of white blood cells. No donor-derived renal tubule cells (RTCs) were detected in kidney sections of BM-recipient mice. However, in cell culture, a cluster of seven donor-derived cells of 4 x 10(6) RTCs examined (approximately 0.0002%) displayed morphological characteristics of RTCs. CD45+ cells of donor origin were also detected in glomeruli and glomerular outgrowths. Nested polymerase chain reaction analysis for the male-specific Sry gene in cultured RTCs and glomerular outgrowths confirmed the presence of donor-derived cells. These results suggest that BMDCs may incorporate into glomeruli as specialized glomerular mesangial cells; however, BMDCs rarely contribute to the repair of renal tubules in uninjured or FA-treated mouse kidneys.

Abstract
Fas ligand (FasL) and perforin pathways not only are the major mechanisms of T cell-mediated cytotoxicity but also are involved in homeostatic regulation of these T cells. In the present study, we tested whether CD8+ donor T cells that are deficient in both perforin and FasL (cytotoxic double deficient [cdd]) could induce graft-versus-host disease (GVHD) in a major histocompatibility complex class I-mismatched lethally irradiated murine model. Interestingly, recipients of cdd CD8+ T cells demonstrated significantly greater serum levels of interferon gamma and tumor necrosis factor alpha and histopathologic damage from GVHD than wild-type (wt) T cells on day 30 after allogeneic bone marrow transplantation (P<.05). Wt and either perforin-deficient or FasL-deficient CD8+ T cells expanded early after transplantation followed by a contraction phase in which the majority of expanded CD8+ T cells were eliminated. In contrast, cdd CD8+ T cells exhibited prolonged expansion and reduced apoptosis to alloantigen stimulation in vivo and in vitro. Together these results suggest that donor cdd CD8+ T cells expand continuously and cause lethal GVHD, and that both perforin and FasL are required for the contraction of allo-reactive CD8+ T cells.

Abstract
Alloantigen expression on host APCs is essential to initiate graft-vs-host disease (GVHD); however, critical APC subset remains to be elucidated. We compared the ability of dendritic cells (DCs) and B cells to initiate acute GVHD by an add-back study of MHC class II-expressing APCs (II(+/+)) into MHC class II-deficient (II(-/-)) mice that were resistant to CD4-dependent GVHD. Injection of host-derived, but not donor-derived, II(+/+) DCs or host-derived II(+/+) B cells, was sufficient to break GVHD resistance of II(-/-) mice and induced lethal acute GVHD. By contrast, host-derived II(+/+) B cells, both naive and LPS stimulated, failed to induce activation or tolerance of donor CD4(+) T cells. Similarly, in a model of CD8-dependent GVHD across MHC class I mismatch injection of allogeneic DCs, but not B cells, induced robust proliferation of donor CD8(+) T cells and broke GVHD resistance of chimeric recipients in which APCs were syngeneic to donors. These results demonstrate that host-derived DCs are critical in priming donor CD4(+) and CD8(+) T cells to cause GVHD, and selective targeting of host DCs may be a promising strategy to prevent GVHD.

Abstract
BACKGROUND Idiopathic pneumonia syndrome (IPS) is a frequent and often fatal complication of allogeneic bone marrow transplantation (BMT). We have previously shown that experimental IPS is associated with alloreactive donor T cells and the inflammatory mediators TNF-alpha and lipopolysaccharide. Both TNF-alpha and lipopolysaccharide are known contributors to endothelial injury. Although damage to vascular endothelia has been associated with other complications after BMT, its relationship to lung injury has not been explored. METHODS We used a well-established murine BMT system, in which lung injury and graft-versus-host disease are induced by minor histocompatibility antigenic differences between donor and host, and the DNA terminal transferase nick-end labeling (TUNEL) procedure to evaluate whether significant pulmonary vascular endothelial cell (EC) apoptosis is present during the development of IPS. RESULTS Our data demonstrate that pulmonary histopathology after allogeneic BMT is accompanied by significant EC apoptosis and the appearance of activated caspase 3. Further evaluation reveals that EC injury coincides with the onset of pulmonary pathology, is associated with elevations in bronchoalveolar lavage fluid tumor necrosis factor (TNF)-alpha levels, and is accompanied by evidence for EC activation. Administration of a soluble TNF-alpha binding protein (recombinant human TNF-alpha receptor:Fc) from week 4 to week 6 after allogeneic BMT significantly reduces EC apoptosis and lung histopathology observed in this setting. CONCLUSIONS EC damage mediated by TNF-alpha is directly linked to the development of experimental IPS. Methods that protect or maintain the integrity of the pulmonary vascular endothelium may therefore prove effective in reducing the severity of lung injury after BMT.

Abstract
Administration of exogenous interleukin-18 (IL-18) regulates experimental acute graft-versus-host disease (GVHD) in a Fas-dependent manner when donor CD4(+) T cells are required for mortality after experimental allogeneic bone marrow transplantation (BMT). However, CD4(+) and CD8(+) T cells can induce acute GVHD after clinical allogeneic BMT, and the role of IL-18 in CD8(+)-mediated acute GVHD is unknown. We, therefore, determined the role of IL-18 in GVHD mediated by CD4(+) or CD8(+) T cells across major histocompatibility complex (MHC) class II- and class I-disparate allogeneic BMT, respectively. Administering IL-18 significantly increased survival in CD4(+)-mediated GVHD but reduced survival in CD8(+)-mediated GVHD. This increase in deaths was associated with significantly greater clinical, biochemical, and histopathologic parameters of GVHD damage and was independent of Fas expression on donor T cells. Administering IL-18 significantly enhanced allospecific cytotoxic function and expansion of CD8(+) cells. Endogenous IL-18 was critical to GVHD mediated by CD8(+) donor T cells because IL-18 receptor-deficient donors caused significantly less GVHD but exacerbated CD4(+)-mediated, GVHD-related death. Furthermore, administering anti-IL-18 monoclonal antibody significantly reduced CD8(+)-mediated, GVHD-related death. Together these findings demonstrate that IL-18 has paradoxical effects on CD4(+) and CD8(+) cell-mediated GVHD.

Abstract
Graft-versus-host disease (GVHD) has been the primary limitation to the wider application of allogeneic bone marrow transplantation (BMT). The immunobiology of acute GVHD is complex and can be conceptualized to be a three-step process. In step 1, the conditioning regimen (irradiation and/or chemotherapy) leads to the damage and activation of host tissues and induces the secretion of inflammatory cytokines TNF-alpha and IL-1. As a consequence expression of MHC antigens and adhesion molecules is increased, thus enhancing the recognition of host alloantigens by donor T cells. Donor T-cell activation in step 2 is characterized by donor T-cell interaction with host APCs and subsequent proliferation, differentiation, and secretion of cytokines. Cytokines such as IL-2 and IFN-gamma enhance T-cell expansion, induce cytotoxic T cells (CTL) and natural killer (NK) cell responses, and prime additional mononuclear phagocytes to produce TNF-alpha and IL-1. These inflammatory cytokines in turn stimulate production of inflammatory chemokines, thus recruiting effector cells into target organs. In step 3, effector functions of mononuclear phagocytes are triggered via a secondary signal provided by lipopolysaccharide (LPS) that leaks through the intestinal mucosa damaged during step 1. This mechanism may result in the amplification of local tissue injury and further promotion of an inflammatory response, which, together with the CTL and NK components, leads to target tissue destruction in the transplant host.

Abstract
We present a phase I design that is a modification to the time-to-event continual reassessment method (TITE-CRM) by Cheung and Chappell that is useful when each dose actually denotes how long a drug is administered. Because of the lengthy duration required for subjects receiving the higher doses, we enroll each subject on the best estimate of the maximum tolerated cumulative dose (MTCD) as soon as each subject is eligible. Once each previously enrolled subject is fully evaluated, we update our estimate of the MTCD and modify currently enrolled subjects to receive the MTCD if they are currently receiving a nonoptimal dose. Thus, our method is adaptive both between subjects and within subjects. We show through simulation that our study design has excellent operating characteristics that are as good as the TITE-CRM while not exposing greater numbers of subjects to doses beyond the MTCD. Our simulations are based upon a study in bone marrow transplant patients that seeks to determine how many weeks of recombinant human keratinocyte growth factor can be administered while keeping toxicity rates below a desired threshold.

Abstract
Acute graft-versus-host disease (GVHD) and leukemic relapse are the two major obstacles to successful outcomes after allogeneic bone marrow transplantation (BMT), an effective therapy for hematological malignancies. Several studies have demonstrated that the dysregulation of proinflammatory cytokines and the loss of gastrointestinal tract integrity contribute to GVHD, whereas the donor cytotoxic responses are critical for graft-versus-leukemia (GVL) preservation. Suberoylanilide hydroxamic acid (SAHA) is currently in clinical trials as an antitumor agent; it inhibits the activity of histone deacetylases and at low doses exhibits antiinflammatory effects by reducing the production of proinflammatory cytokines. Using two well characterized mouse models of BMT, we have studied the effects of SAHA on GVHD severity and GVL activity. Administration of SAHA from day +3 to day +7 after BMT reduced serum levels of the proinflammatory cytokines and decreased intestinal histopathology, clinical severity, and mortality from acute GVHD compared with vehicle-treated animals. However, SAHA had no effect on donor T cell proliferative and cytotoxic responses to host antigens in vivo or in vitro. When mice received lethal doses of tumor cells at the time of BMT, administration of SAHA did not impair GVL activity and resulted in significantly improved leukemia-free survival by using two different tumor and donor/recipient combinations. These findings reveal a critical role for histone deacetylase inhibition in the proinflammatory events contributing to GVHD and suggest that this class of pharmacologic agents may provide a strategy to reduce GVHD while preserving cytotoxic T cell responses to host antigens and maintaining beneficial GVL effects.

Abstract
We describe here a patient who died of progressive CNS deterioration following allogeneic stem cell transplant with West Nile virus as the sole pathogen on the cerebrospinal fluid and brain tissue analysis. A 50-year-old male with Philadelphia chromosome-positive acute lymphocytic leukemia (ALL) underwent allogeneic PBSCT from his HLA identical sister. After engraftment, the patient developed fever with progressive and ultimately fatal neurological deterioration. Imaging studies of the brain including CT and MRI scans were remarkable for mild low attenuation lesions of the white matter. CSF analysis was negative for neoplastic cells, bacteria, AFB, CMV, HSV, fungal infections and leukemic relapse. However, serological analysis of both the serum and CSF was positive for West Nile virus-specific IgM antibodies. At autopsy, West Nile virus PCR and cultures were positive in the mid-brain tissue. Electron micrographs showed evidence of viral particles. Given the recent increase in the spread of West Nile virus infections and the increased susceptibility of BMT patients to infectious complications, West Nile virus encephalitis should be considered in patients undergoing transplantation.

Abstract
OBJECTIVE The chemokine receptor CXCR3 has an important role in the migration of effector T cells. To investigate the role of CXCR3 on donor cells in acute graft vs host disease (GVHD) we used a well-defined experimental bone marrow transplantation (BMT) model where acute GVHD is mediated by donor CD8(+) T cells against minor histocompatibility antigens. METHODS; Lethally irradiated C3H.SW recipients were transplanted from either wild-type B6 or CXCR3(-/-) B6 donors. Donor T-cell expansion was analyzed in the spleen and small intestine of recipients by FACS. Donor T-cell function was analyzed by cytokine secretion. The severity of acute GVHD was assessed by histopathological analysis of intestine and liver, GVHD clinical scores, and survival after BMT. RESULTS Significantly higher numbers of donor CD8(+) CXCR3(-/-) T cells were found in the spleen on days +7 and +14 compared to donor wild-type T cells. By contrast, the number of CD8(+) T cells in the small bowel of BMT recipients from CXCR3(-/-) donors was sevenfold lower than from wild-type donors. Systemic concentrations of INF-gamma and TNF-alpha were equivalent between groups. Animals that received CXCR3(-/-) donor T cells demonstrated diminished GI tract and liver damage and showed improved survival after BMT compared to recipients of wild-type donor cells (43% vs 0%, p<0.001). CONCLUSION The migration of donor CD8(+) T cells to GVHD target organs such as the intestine depends on the expression of CXCR3 and contributes significantly to GVHD damage and overall mortality.

Abstract
The pathophysiology of acute graft-versus-host disease (GVHD) is a complex process that can be conceptualized in three phases. In the first phase, high-dose chemoradiotherapy causes damage to host tissues, including a self-limited burst of inflammatory cytokines such as tumor necrosis factor (TNF)-alpha and interleukin 1. These cytokines activate host antigen-presenting cells (APCs). In the second phase, donor T-cells recognize alloantigens on host APCs. These activated T-cells then proliferate, differentiate into effector cells, and secrete cytokines, particularly interferon (IFN)-gamma. In the third phase, target cells undergo apoptosis mediated by cellular effectors (eg, donor cytotoxic T-lymphocytes) and inflammatory cytokines such as TNF-alpha. TNF-alpha secretion is amplified by stimuli such as endotoxin that leaks across damaged gastrointestinal mucosa injured by the chemoradiotherapy in the first phase. TNF-alpha and IFN-gamma cause further injury to gastrointestinal epithelium, causing more endotoxin leakage and establishing a positive inflammatory feedback loop. These events are examined in detail in the following review.

Abstract
Graft-versus-host disease (GVHD) is the principal complication after allogeneic bone marrow transplantation (BMT). Reductions in systemic GVHD are frequently associated with a corresponding diminishment of the graft-versus-leukemia (GVL) response. In this study, we tested the effects of a novel recombinant human keratinocyte growth factor, repifermin (keratinocyte growth factor-2), on the induction of GVHD in a well-defined murine BMT model (B6 --> B6D2F1). Administration of repifermin (5 mg/kg/d) to allogeneic BMT recipients resulted in a significant decrease in both systemic GVHD and target organ histopathology. Repifermin treatment also reduced serum levels of tumor necrosis factor alpha and lipopolysaccharide compared with control mice. In contrast, repifermin did not affect T-cell proliferation, cytokine production, or cytotoxic responses to host antigens. When 2000 host-derived P815 (H-2(d)) leukemia cells were added to the bone marrow inoculum, repifermin preserved GVL effects and resulted in significantly delayed mortality compared with control-treated allogeneic BMT recipients. Collectively, these data suggest that repifermin administration may represent a novel strategy to separate the toxicity of GVHD from the beneficial GVL effects after allogeneic BMT.

Abstract
We reviewed the clinical outcome of 8 patients with steroid-refractory chronic graft-versus-host disease (GVHD) who received an anti-CD20 chimeric monoclonal antibody (rituximab). Rituximab was given by intravenous infusion at a weekly dose of 375 mg/m(2) for 4 weeks. All patients had received extensive treatment with various immunosuppressive agents; 6 patients had also received extracorporeal photopheresis. All patients had extensive chronic GVHD with diffuse or localized sclerodermoid GVHD and xerophthalmia. Other extracutaneous involvements included cold agglutinin disease with the Raynaud phenomenon, membranous glomerulonephritis, and restrictive or obstructive lung disease. Four patients responded to treatment with ongoing resolution or improvement ranging from 265 to 846 days after therapy, despite recovery of B cells in 3 patients. Rituximab seems to have significant activity in the treatment of refractory chronic GVHD and should be considered for further study in patients with early disease. This study suggests a participating role of B cells in the pathogenesis of chronic GVHD.

Abstract
Allogeneic stem cell transplantation (SCT) is an important therapy for a number of malignant diseases, and acute graft versus host disease (GVHD) and leukemic relapse remain the two major obstacles to successful outcomes of this treatment strategy. The therapeutic potential of allogeneic SCT relies on the graft versus leukemia (GVL) effect, during which donor T lymphocytes eradicate residual malignant cells via immunological mechanisms. Unfortunately, beneficial GVL effects are closely associated with the toxicity of GVHD. The pathophysiology of GVHD is complex and fundamentally depends upon aspects of adaptive immunity and interactions between donor T cells and foreign host tissue antigens. Recent work has revealed that components of the innate immune response and the secretion of inflammatory cytokine effectors are also important. In this context, experimental studies have demonstrated that loss of gastrointestinal (GI) tract integrity plays a major role in the amplification of systemic GVHD. Specifically, translocation of endotoxin across a damaged GI tract and into the circulation promotes local and systemic cytokine release. This effect perpetuates further gut mucosal injury and endotoxin leak, thus establishing a positive feedback loop for progressive target organ injury and systemic inflammation. Data obtained using murine SCT models have shown that disruption of the cellular activating effects of lipopolysaccharide (LPS) significantly reduces cytokine secretion and GVHD severity without altering T-cell responses to host antigens. These findings support a critical role for LPS in the early inflammatory events responsible for GVHD and suggest that strategies which target the innate immune response and LPS receptor-ligand interactions may help prevent GVHD while preserving donor T-cell responses and GVL activity.

Abstract
Animal models with impaired thymic negative selection do not always cause autoimmune diseases despite the development of an autoreactive T-cell repertoire. We investigated the requirements for the development of systemic autoimmune disease by using bone marrow chimeras that lacked expression of major histocompatibility complex (MHC) class II on thymic antigen-presenting cells (APCs), leading to impaired negative selection. We found that impaired negative selection mediated by absence of MHC class II, but not MHC class I, permitted the development of systemic autoimmune disease that is indistinguishable from acute graft-versus-host disease (GVHD). Thymectomy prevented disease, confirming the causal association of the thymus with its development. Adoptive transfer of CD4+ T cells caused GVHD in secondary hosts only when they were irradiated, and cotransfer of peripheral CD4+ and CD8+ T cells from naive mice prevented the disease. These results demonstrate that impaired thymic negative selection can cause lethal autoimmune disease indistinguishable from acute GVHD in the context of a proinflammatory milieu when peripheral regulatory mechanisms are absent.

Abstract
The liver, skin, and gastrointestinal tract are major target organs of acute graft-versus-host disease (GVHD), the major complication of allogeneic bone marrow transplantation (BMT). In order to gain a better understanding of acute GVHD in the liver, we compared the gene expression profiles of livers after experimental allogeneic and syngeneic BMT using oligonucleotide microarray. At 35 days after allogeneic BMT when hepatic GVHD was histologically evident, genes related to cellular effectors and acute-phase proteins were up-regulated, whereas genes largely related to metabolism and endocrine function were down-regulated. At day 7 after BMT before the development of histologic changes in the liver, interferon gamma (IFN-gamma)-inducible genes, major histocompatibility (MHC) class II molecules, and genes related to leukocyte trafficking had been up-regulated. Immunohistochemistry demonstrated that expression of IFN-gamma protein itself was increased in the spleen but not in hepatic tissue. These results suggest that the increased expression of genes associated with the attraction and activation of donor T cells induced by IFN-gamma early after BMT is important in the initiation of hepatic GVHD in this model and provide new potential molecular targets for early detection and intervention of acute GVHD.

Abstract
Acute pulmonary dysfunction remains a frequent and severe complication of hematopoietic stem cell transplantation (SCT). Almost half of the pulmonary insults that occur in this seating are noninfectious in origin and are referred to as idiopathic pneumonia syndrome (IPS). In this series of 3 patients, etanercept (Enbrel; Immunex, Seattle, WA), a soluble, dimeric tumor necrosis factor alpha-binding protein, was administered to 3 consecutive pediatric allogeneic BMT recipients with IPS. The administration of etanercept, in combination with standard immunosuppressive therapy, was well tolerated and associated with significant improvements in pulmonary dysfunction within the first week of therapy. These data suggest that etanercept may represent a safe, non-cross-reactive, therapeutic option for patients with IPS and that clinical trials studying etanercept for this indication are warranted.

Abstract
Allogeneic hematopoietic cell transplantation (HCT) has emerged as an important therapeutic option for several malignant and nonmalignant diseases. In addition to delivering systemic chemoradiotherapy, the therapeutic potential of allogeneic HCT relies on the graft-vs-leukemia (GVL) effect, which eradicates residual malignant cells by way of immunologic mechanisms. Unfortunately, GVL effects are closely associated with graft-vs-host disease (GVHD), the major complication of allogeneic HCT. Separation of the toxicity of acute GVHD from the beneficial GVL effects remains a major challenge to expanding the utility of this effective treatment modality. The pathophysiology of acute GVHD involves dysregulation of inflammatory cytokine cascades and donor T-cell responses to host alloantigens. Interleukin 18 (IL-18) is a recently discovered cytokine with potent immunomodulatory effects. This unique cytokine has the capacity to induce Th1 or Th2 polarization, depending on the immunologic context. The level of IL-18 is increased in acute GVHD, but this cytokine's role in the pathophysiology of acute GVHD is complex. It reduces the severity of acute GVHD as a T helper 1 (Th1)-inducing cytokine when administered early after bone-marrow transplant to the lethally irradiated recipients. When administered to the donor, it can also reduce the severity of acute GVHD, as a T helper 2 (Th2)-inducing cytokine. Despite reducing the severity of acute GVHD, IL-18 preserves the GVL effect after bone-marrow transplant. Thus IL-18 has the remarkable capacity to modulate acute GVHD when administered either to the donor or the recipient through distinct mechanisms.

Abstract
Interleukin-18 (IL-18) is a unique cytokine that modulates both T(H)1/T(H)2 responses, but its ability to modulate diseases through induction of T(H)2 cytokines is unclear. It has been shown to play an important role in allogeneic bone marrow transplantation (BMT). Because immune responses of allogeneic BM donors may affect acute graft-versus-host disease (GVHD), we investigated the effect of pretreating BM transplant donors with IL-18 on the severity of acute GVHD using a well-characterized experimental BMT model (BALB/c-->B6). Pretreatment of allogeneic BM transplant donors with IL-18 significantly improved survival (80% vs 0%; P <.001), and reduced clinical, biochemical, and pathologic indices of acute GVHD in BM transplant recipients. IL-18 pretreatment was associated with reduced interferon gamma (IFN-gamma) and greater IL-4 secretion by donor T cells after BMT. Acute GVHD mortality was reduced when IL-18 was administered to donors deficient in IFN-gamma and signal transducer and activator of transcription 4 (STAT4) but not STAT6 signaling molecules, suggesting a critical role for STAT6 signaling in IL-18's protective effect. IL-18 treatment did not alter donor CD8(+) cytotoxic T-lymphocyte (CTL) activity and preserved graft-versus-leukemia (GVL) effects after allogeneic BMT (70% vs 10%; P <.01). Together these data illustrate that pretreatment of donors with IL-18 prior to allogeneic BMT attenuates acute GVHD in a STAT6-dependent mechanism while preserving GVL effects.

Abstract
The granulocyte colony-stimulating factor (G-CSF) and Flt-3 receptor agonist progenipoietin-1 (ProGP-1) has potent effects on dendritic cell (DC) expansion and may be an alternative to G-CSF for the mobilization of stem cells for allogeneic stem cell transplantation (SCT). We studied the ability of stem cell grafts mobilized with this agent to induce graft-versus-host disease (GVHD) to minor and major histocompatibility antigens in the well-described B6 --> B6D2F1 SCT model. ProGP-1, G-CSF, or control diluent was administered to donor B6 mice. ProGP-1 expanded all cell lineages in the spleen, and unseparated splenocytes from these animals produced large amounts of interleukin 10 (IL-10) and transforming growth factor beta (TGFbeta) whereas the expression of T-cell adhesion molecules was diminished. Transplantation survival was 0%, 50%, and 90% in recipients of control-, G-CSF-, and ProGP-1-treated allogeneic donor splenocytes, respectively (P <.0001). Donor pretreatment with ProGP-1 allowed a 4-fold escalation in T-cell dose over that possible with G-CSF. Donor CD4 T cells from allogeneic SCT recipients of ProGP-1 splenocytes demonstrated an anergic response to host antigen, and cytokine production (interferon gamma [IFNgamma], IL-4, and IL-10) was also reduced while CD8 T-cell cytotoxicity to host antigens remained intact. Neither CD11c(hi) DCs nor CD11c(dim)/B220(hi) DCs from ProGP-1-treated animals conferred protection from GVHD when added to control spleen. Conversely, when equal numbers of purified T cells from control-, G-CSF-, or ProGP-1-treated allogeneic donors were added to allogeneic T-cell-depleted control spleen, survival at day 60 was 0%, 15%, and 90%, respectively (P <.0001). The improved survival in recipients of ProGP-1 T cells was associated with reductions in systemic tumor necrosis factor alpha generation and GVHD of the gastrointestinal tract. We conclude that donor pretreatment with ProGP-1 is superior to G-CSF for the prevention of GVHD after allogeneic SCT, primarily due to incremental affects on T-cell phenotype and function.

Abstract
The idiopathic pneumonia syndrome (IPS) represents a common and often fatal complication of hematopoietic stem cell transplantation (HSCT). Gelsolin is a highly conserved actin-binding protein normally present in plasma that may serve a basic physiological role in limiting acute lung injury of diverse etiologies. We hypothesized that depletion of circulating gelsolin following HSCT might play a permissive role in the pathogenesis of IPS. Plasma gelsolin levels were measured by immunoblotting in frozen samples obtained weekly from 24 patients undergoing allogeneic HSCT. Patients with and without IPS were similar with respect to age, diagnosis, histocompatibility differences between donor and recipient, and conditioning regimen. Mean gelsolin levels in the 9 patients with rapidly fatal IPS were significantly lower than those in patients without this complication by week 3 after HSCT (101 +/- 61 mg/L versus 221 +/- 54 mg/L; P =.0002). Seven (88%) of the 8 patients with gelsolin levels of less than 100 mg/L in the first month after HSCT died from IPS within 3 months; conversely, gelsolin levels fell to less than 100 mg/L in 7 (78%) of the 9 patients who died from IPS within 3 months of HSCT (P =.0007). These findings suggest that gelsolin levels shortly after allogeneic HSCT can predict the later development of fatal IPS. Gelsolin replacement in selected transplant patients may offer a novel strategy to prevent or reverse IPS.

Abstract
Acute graft-versus-host disease (GVHD) is thought to derive from direct T-cell injury of target tissues through perforin/granzyme, Fas/FasL interactions, and the effects of inflammatory cytokines. Animal models and some clinical trials support the notion that inhibition of inflammatory mediators such as interleukin-1 (IL-1), tumor necrosis factor alpha, and interferon gamma may ameliorate or prevent GVHD. We hypothesized that blockade of IL-1 during the period of initial T-cell activation would reduce the risk of severe GVHD. We tested this hypothesis in a double-blind, placebo-controlled randomized trial of recombinant human IL-1 receptor antagonist (IL-1Ra) in 186 patients undergoing allogeneic stem cell transplantation. Randomization was stratified by degree of histocompatibility and stem cell source. All patients were conditioned with cyclophosphamide and total body irradiation. GVHD prevention consisted of cyclosporine and methotrexate in all patients. Recombinant human IL-1Ra or saline placebo was given from day -4 to day +10. Randomization was stratified according to GVHD risk. The 2 groups were well-matched for pretreatment characteristics. Moderate to severe GVHD (grades B-D) developed in 57 (61%) of 94 patients receiving IL-1Ra and in 51 (59%) of 86 patients on placebo (P =.88). There was no difference in hematologic recovery, transplantation-related toxicity, event-free survival, or overall survival. We conclude that blockade of IL-1 using IL-1Ra during conditioning and 10 days immediately after transplantation is not sufficient to reduce GVHD or toxicity or to improve survival.

Abstract
We have recently shown that early administration of interleukin 18 (IL-18) after bone marrow transplantation (BMT) attenuates acute graft-versus-host disease (GVHD) in a lethally irradiated parent into F1 (B6-->B6D2F1) BMT model. In this study, we investigated whether IL-18 can maintain graft-versus-leukemia (GVL) effect in this context. B6D2F1 mice received transplants of T-cell-depleted (TCD) bone marrow (BM) and splenic T cells from either syngeneic (H2(b/d)) or allogeneic B6 (H2(b)) donors. Recipient mice were treated with recombinant murine IL-18 or the control diluent. Initial studies demonstrated that IL-18 treatment did not affect the proliferative responses or the cytolytic effector functions of T cells after BMT. In subsequent experiments, animals also received host-type P815 mastocytoma cells at the time of BMT. All syngeneic BM transplant recipients died from leukemia by day 18. The allogeneic BM transplant recipients effectively rejected their leukemia regardless of treatment and IL-18 significantly reduced GVHD-related mortality. Examination of the cytotoxic mechanisms with perforin-deficient donor T cells demonstrated that perforin is critical for the GVL effect. Taken together these data demonstrate that IL-18 can attenuate acute GVHD without impairing the in vitro cytolytic function or the in vivo GVL activity after allogeneic BMT.
