Abstract
Allogeneic hematopoietic stem cell transplantation (HSCT) is a potentially curative therapy for many hematologic malignancies as well as non-malignant conditions. Part of the curative basis underlying HSCT for hematologic malignancies relies upon induction of the graft versus leukemia (GVL) effect in which donor immune cells recognize and eliminate residual malignant cells within the recipient, thereby maintaining remission. GVL is a clinically evident phenomenon; however, specific cell types responsible for inducing this effect and molecular mechanisms involved remain largely undefined. One of the best examples of GVL is observed after donor lymphocyte infusions (DLI), an established therapy for relapsed disease or incipient/anticipated relapse. DLI involves infusion of peripheral blood lymphocytes from the original HSCT donor into the recipient. Sustained remission can be observed in 20-80% of patients treated with DLI depending upon the underlying disease and the intrinsic burden of targeted cells. In this review, we will discuss current knowledge about mechanisms of GVL after DLI, experimental strategies for augmenting GVL by manipulation of DLI (e.g. neoantigen vaccination, specific cell type selection/depletion) and research outlook for improving DLI and cellular immunotherapies for hematologic malignancies through better molecular definition of the GVL effect.

Schroeder SM, Nelde A, Walz JS. Viral T-cell epitopes - Identification, characterization and clinical application. Semin Immunol 2023; 66:101725.

Abstract
T-cell immunity, mediated by CD4+ and CD8+ T cells, represents a cornerstone in the control of viral infections. Virus-derived T-cell epitopes are represented by human leukocyte antigen (HLA)-presented viral peptides on the surface of virus-infected cells. They are the prerequisite for the recognition of infected cells by T cells. Knowledge of viral T-cell epitopes provides on the one hand a diagnostic tool to decipher protective T-cell immune responses in the human population and on the other hand various prophylactic and therapeutic options including vaccination approaches and the transfer of virus-specific T cells. Such approaches have already been proven to be effective against various viral infections, particularly in immunocompromised patients lacking sufficient humoral, antibody-based immune response. This review provides an overview on the state of the art as well as current studies regarding the identification and characterization of viral T-cell epitopes and approaches of clinical application. In the first chapter in silico prediction tools and direct, mass spectrometry-based identification of viral T-cell epitopes is compared. The second chapter provides an overview of commonly used assays for further characterization of T-cell responses and phenotypes. The final chapter presents an overview of clinical application of viral T-cell epitopes with a focus on human immunodeficiency virus (HIV), human cytomegalovirus (HCMV) and severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), being representatives of relevant viruses.

Basiliximab for steroid-refractory acute graft-versus-host disease: A real-world analysis. Am J Hematol 2022; 97:458-469. [PMID: 35064928 DOI: 10.1002/ajh.26475] [Citation(s) in RCA: 20] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2021] [Revised: 01/14/2022] [Accepted: 01/18/2022] [Indexed: 02/05/2023]
Abstract
Steroid-refractory (SR) acute graft-versus-host disease (aGVHD) is one of the leading causes of early mortality after allogeneic hematopoietic stem cell transplantation (allo-HSCT). We investigated the efficacy, safety, prognostic factors, and optimal therapeutic protocol for SR-aGVHD patients treated with basiliximab in a real-world setting. Nine hundred and forty SR-aGVHD patients were recruited from 36 hospitals in China, and 3683 doses of basiliximab were administered. Basiliximab was used as monotherapy (n = 642) or in combination with other second-line treatments (n = 298). The cumulative incidence of overall response rate (ORR) at day 28 after basiliximab treatment was 79.4% (95% confidence interval [CI] 76.5%-82.3%). The probabilities of nonrelapse mortality and overall survival at 3 years after basiliximab treatment were 26.8% (95% CI 24.0%-29.6%) and 64.3% (95% CI 61.2%-67.4%), respectively. A 1:1 propensity score matching was performed to compare the efficacy and safety between the monotherapy and combined therapy groups. Combined therapy did not increase the ORR; conversely, it increased the infection rates compared with monotherapy. The multivariate analysis showed that combined therapy, grade III-IV aGVHD, and high-risk refined Minnesota aGVHD risk score before basiliximab treatment were independently associated with the therapeutic response. Hence, we created a prognostic scoring system that could predict the risk of having a decreased likelihood of response after basiliximab treatment. Machine learning was used to develop a protocol that maximized the efficacy of basiliximab while maintaining acceptable levels of infection risk. Thus, real-world data suggest that basiliximab is safe and effective for treating SR-aGVHD.

Abstract
BACKGROUND Cure of acute leukemia after transplantation is mediated by the grafted cells. We investigated the graft-versus-leukemia effect (GVL) in patients with cutaneous acute graft-versus-host disease (GVHD) treated with photochemotherapy (psoralen and ultraviolet light type A). METHOD Forty-seven patients with acute leukemia were followed 5,000 days after transplantation to assess survival and GVL by multivariate analysis. The primary predictor was time to treatment of cutaneous acute GVHD by photochemotherapy separated into treatment start during the first week of acute GVHD versus after the first week of acute GVHD. RESULTS Photochemotherapy started after the first week of acute GVHD predicted GVL with a hazard ratio (HR) of 3.94 (95% confidence interval, CI, 1.67-9.33, p = 0.0018) and survival with preserved GVL with an HR of 2.63 (95% CI 1.30-5.32, p = 0.007). The effects on GVL and survival with preserved GVL were present regardless of whether the patients were transplanted in remission or relapse (p < 0.05). Chronic GVHD came earlier in the group that started photochemotherapy after 1 week of acute GHVD, but chronic GVHD did not increase the GVL. CONCLUSION The timing of photochemotherapy after cutaneous acute GVHD may direct the GVL and predict long-term leukemia-free survival.

Abstract
Adoptive natural regulatory T cell (nTreg) therapy has improved the outcome for patients suffering from graft-versus-host disease (GVHD) following allogeneic hematopoietic cell transplantation (Allo-HCT). However, fear of broad immune suppression and subsequent dampening of beneficial graft-versus-leukemia (GVL) responses remains a challenge. To address this concern, we generated alloreactive induced Tregs (iTregs) from resting CD4(+) or CD8(+) T cells and tested their ability to suppress GVH and maintain GVL responses. We utilized major mismatched and haploidentical murine models of HCT with host-derived lymphoma or leukemia cell lines to evaluate GVH and GVL responses simultaneously. Alloreactive CD4(+) iTregs were effective in preventing GVHD, but abrogated the GVL effect against aggressive leukemia. Alloreactive CD8(+) iTregs moderately attenuated GVHD while sparing the GVL effect. Hence, we reasoned that using a combination of CD4(+) and CD8(+) iTregs could achieve the optimal goal of Allo-HCT. Indeed, the combinational therapy was superior to CD4(+) or CD8(+) iTreg singular therapy in GVHD control; importantly, the combinational therapy maintained GVL responses. Cellular analysis uncovered potent suppression of both CD4(+) and CD8(+) effector T cells by the combinational therapy that resulted in effective prevention of GVHD, which could not be achieved by either singular therapy. Gene expression profiles revealed alloreactive CD8(+) iTregs possess elevated expression of multiple cytolytic molecules compared to CD4(+) iTregs, which likely contributes to GVL preservation. Our study uncovers unique differences between alloreactive CD4(+) and CD8(+) iTregs that can be harnessed to create an optimal iTreg therapy for GVHD prevention with maintained GVL responses.

Abstract
Hematopoietic stem cell transplantation has been used for more than 50 years to combat hematologic malignancies. In addition to being the first stem cell therapy, transplantation has provided evidence for the potent anti-tumor effects of T cells. Facilitating T-cell-based immunity against malignancies requires a careful balancing act between generating a robust response and avoiding off-target killing of healthy tissues, which is difficult to accomplish using bulk donor T cells. To address these issues, several approaches have been developed, drawing on basic T-cell biology, to potentiate graft-versus-tumor activity while avoiding graft-versus-host disease. Current strategies for anti-tumor cell therapies include: (i) selecting optimal T cells for transfer; (ii) engineering T cells to possess enhanced effector functions; and (iii) generating T-cell precursors that complete development after adoptive transfer. In this review, we assess the current state of the art in T-lineage cell therapy to treat malignancies in the context of allogeneic hematopoietic stem cell transplantation.

Abstract
Allogeneic hematopoietic stem-cell transplantation (HSCT) is the most effective approach for many patients with hematologic malignancies. Unfortunately, relapse remains the most common cause of death after allogeneic HSCT, and the prognosis of relapsed disease is poor for most patients. Induction of a graft-versus-leukemia (GVL), or graft-versus-tumor, effect through the use of donor leukocyte infusion (DLI), or donor lymphocyte infusion, has been remarkably successful for relapsed chronic myelogenous leukemia. Unfortunately, response to DLI in other hematologic malignancies is much less common and depends on many factors including histology, pace and extent of relapse, and time from HSCT to relapse. Furthermore, graft-versus-host disease (GVHD) is common after DLI and often limits successful immunotherapy. Ultimately, manipulations to minimize GVHD while preserving or enhancing GVL are necessary to improve outcomes for relapse after allogeneic HSCT.

Donor lymphocyte infusion for relapsed hematological malignancies after allogeneic hematopoietic cell transplantation: prognostic relevance of the initial CD3+ T cell dose.

Abstract
The impact of donor lymphocyte infusion (DLI) initial cell dose on its outcome is known in patients with chronic myeloid leukemia but limited in patients with other hematological malignancies. In this retrospective study, we evaluated the effect of initial DLI CD3(+) cell dose on graft-versus-host disease (GVHD) and overall survival after DLI given for relapse of any hematological malignancies after allogeneic hematopoietic cell transplantation (HCT) with high- or reduced-intensity conditioning. The cohort included 225 patients. Initial DLI CD3(+) cell dose per kilogram of recipient body weight was ≤ 1 × 10(7) (n = 84; group A), >1.0 to <10 × 10(7) (n = 58; group B), and ≥ 10 × 10(7) (n = 66; group C). The initial cell dose was unknown for the remaining 17 patients. Cumulative incidence rates of GVHD at 12 months after DLI were 21%, 45%, and 55% for groups A, B, and C, respectively. Multivariate analysis showed that initial DLI CD3(+) cell ≥ 10 × 10(7) dose per kilogram is associated with an increased risk of GVHD after DLI (P = .03). Moreover, an initial DLI CD3(+) cell dose of 10 × 10(7) or higher did not decrease the risk of relapse and did not improve overall survival. Thus, these results support the use of less than 10 × 10(7) CD3(+) cell per kilogram as the initial cell dose of DLI for treatment of persistent or recurrent hematological malignancy after HCT.

Abstract
Donor leukocyte infusions induce remissions in some patients with hematologic malignancies who relapse after allogeneic hematopoietic cell transplantation (HCT); however, graft-versus-host disease (GVHD) remains the major complication of this strategy. Cytokine-induced killer (CIK) cells are a unique population of cytotoxic T lymphocytes that express the CD3(+)CD56(+) phenotype and show marked up-regulation of the natural killer cell receptor NKG2D (CD314). CIK cells are non-major histocompatibility complex-restricted and NKG2D-dependent in target recognition and cytotoxicity. We explored the feasibility of ex vivo expansion of allogeneic CIK cells in patients with relapsed hematologic malignancies after allogeneic HCT. Eighteen patients (median age, 53 years; range, 20-69 years) received CIK cell infusions at escalating doses of 1 × 10(7) CD3(+) cells/kg (n = 4), 5 × 10(7) CD3(+) cells/kg (n = 6), and 1 × 10(8) CD3(+) cells/kg (n = 8). The median expansion of CD3(+) cells was 12-fold (range, 4- to 91-fold). CD3(+)CD56(+) cells represented a median of 11% (range, 4%-44%) of the harvested cells, with a median 31-fold (range, 7- to 515-fold) expansion. Median CD3(+)CD314(+) cell expression was 53% (range, 32%-78%) of harvested cells. Significant cytotoxicity was demonstrated in vitro against a panel of human tumor cell lines. Acute GVHD grade I-II was seen in 2 patients, and 1 patient had limited chronic GVHD. After a median follow-up of 20 months (range, 1-69 months) from CIK infusion, the median overall survival was 28 months, and the median event-free survival was 4 months. All deaths were due to relapsed disease; however, 5 patients had longer remissions after infusion of CIK cells than from allogeneic HCT to relapse. Our findings indicate that this form of adoptive immunotherapy is well tolerated and induces a low incidence of GVHD, supporting further investigation as an upfront modality to enhance graft-versus-tumor responses in high-risk patient populations.

Abstract
BACKGROUND One of the major challenges in allogeneic stem cell transplantation is to find a balance between the harmful induction of graft-versus-host disease and the beneficial graft-versus-leukemia and pathogen-specific immune responses. Adoptive transfer of in-vitro generated donor T cells with specific anti-leukemic or pathogen-specific activity may be effective. However, in many cases this requires the in-vitro priming and expansion of antigen-specific precursor T cells from the naïve donor T-cell repertoire. DESIGN AND METHODS Antigen-specific CD8 T cells were generated by co-culture of CD45RO-depleted, regulatory T cell-depleted donor peripheral blood mononuclear cells with autologous peptide-loaded dendritic cells, followed by two re-stimulations with peptide-loaded autologous monocytes. Responding T cells were isolated based on CD137 expression and further purified using peptide/major histocompatibility complex tetramers. RESULTS Using this method we were able to reproducibly generate functionally high avidity T cells directed against multiple viral antigens and minor histocompatibility antigens from the naïve T-cell repertoire of seronegative, minor histocompatibility antigen-negative donors. Furthermore, we demonstrated that reduction of the regulatory T-cell frequency by depletion of CD45RO(+) responder cells resulted in improved priming and expansion of antigen-specific precursor T cells. CONCLUSIONS In conclusion, we present a robust method for the in-vitro induction and isolation of antigen-specific T cells from the naïve repertoire. We demonstrate that the likelihood of successful generation of primary immune responses is determined by a delicate balance between the numbers of antigen-specific precursor T cells and the numbers and activation state of regulatory T cells locally at the site of priming of the immune response.

Abstract
OBJECTIVE Cell trafficking during pregnancy results in persistence of small populations of fetal cells in the mother, known as fetal microchimerism (FMc). Changes in cell-free fetal DNA during gestation have been well described, however, less is known about dynamic changes in fetal immune cells in maternal blood. We have investigated FMc in maternal peripheral blood mononuclear cells (PBMC) longitudinally across gestation. STUDY DESIGN Thirty-five women with normal pregnancies were studied. FMc was identified in PBMC, CD4+ and CD8+ subsets employing quantitative PCR assays targeting fetal-specific genetic polymorphisms. FMc quantities were reported as fetal genome equivalents (gEq) per 1,000,000 gEq mother's cells. Poisson regression modeled the rate of FMc detection. MAIN OUTCOME MEASURE FMc in PBMC. RESULTS The probability of detecting one fetal cell equivalent increased 6.2-fold each trimester [Incidence Rate Ratio (IRR) 95% CI: 1.73, 21.91; p = 0.005]. Although FMc in PBMC was not detected for the majority of time points, 7 of 35 women had detectable FMc during pregnancy at one or more time points, with the majority of positive samples being from the third trimester. There was a suggestion of greater HLA-sharing in families where women had FMc in PBMC. FMc was detected in 9% of CD4+ (2/23) and 18% of CD8+ (3/25) subsets. CONCLUSIONS FMc in PBMC increased as gestation progressed and was found within CD4+ and CD8+ subsets in some women in the latter half of gestation. A number of factors could influence cellular FMc levels including sub-clinical fetal-maternal interface changes and events related to parturition. Whether FMc during pregnancy predicts persistent FMc and/or correlates with fetal-maternal HLA relationships also merits further study.

Abstract
Leukemia relapse is a serious therapeutic challenge following hematopoietic stem cell transplantation (HSCT). In this retrospective study, 23 patients [15 (65.2%) AML, 8 (34.8%) ALL] who received DLI+/-reinduction chemotherapy for post-transplant relapse were reviewed. The overall response rate of DLI was 66.7% for AML and 50% for ALL. A total of 15 patients (65.2%) developed acute graft versus host disease (GVHD). Response rates were higher in patients with GVHD (80% versus 25%; p=0.01; OR: 12.0). The probability of OS was better in patients who respond to DLI (p=0.04). Further strategies are required to improve the anti-tumor properties of alloreactive donor lymphocytes and to obtain durable responses with DLI in patients with relapsed acute leukemia after allogeneic HSCT.

Abstract
Immunodeficient mice have been used as recipients of human peripheral blood mononuclear cells (PBMC) for in vivo analyses of human xeno-graft-versus-host disease (GVHD). This xeno-GVHD model system in many ways mimics the human disease. The model system is established by intravenous or intraperitoneal injection of human PBMC or spleen cells into unconditioned or irradiated immunodeficient recipient mice. Recently, the development of several stocks of immunodeficient Prkdc ( scid ) (scid) and recombination activating 1 or 2 gene (Rag1 or Rag2) knockout mice bearing a targeted mutation in the gene encoding the IL2 receptor gamma chain (IL2rgamma) have been reported. The addition of the mutated IL2rgamma gene onto an immunodeficient mouse stock facilitates heightened engraftment with human PBMC. Stocks of mice with mutations in the IL2rgamma gene have been studied in several laboratories on NOD-scid, NOD-Rag1 ( null ), BALB/c-Rag1 ( null ), BALB/c-Rag2 ( null ), and Stock-H2(d)-Rag2 ( null ) strain backgrounds. Parameters to induce human xeno-GVHD in H2(d)-Rag2 ( null ) IL2rgamma ( null ) mice have been published, but variability in the frequency of disease and kinetics of GVHD were observed. The availability of the NOD-scid IL2rgamma ( null ) stock that engrafts more readily with human PBMC than does the Stock-H2(d)-Rag2 ( null ) IL2rgamma ( null ) stock should lead to a more reproducible humanized mouse model of GVHD and for the use in drug evaluation and validation. Furthermore, GVHD in human PBMC-engrafted scid mice has been postulated to result predominately from a human anti-mouse major histocompatibility complex (MHC) class II reactivity. Our recent development of NOD-scid IL2rgamma ( null ) beta2m ( null ) and NOD-scid IL2rgamma ( null ) Ab ( null ) stocks of mice now make it possible to investigate directly the role of host MHC class I and class II in the pathogenesis of GVHD in humanized mice using NOD-scid IL2rgamma ( null ) stocks that engraft at high levels with human PBMC and are deficient in murine MHC class I, class II, or both classes of MHC molecules.

Abstract
PURPOSE OF REVIEW Myelodysplastic syndromes (MDS) are characterized by chronic cytopenias and a high risk of transformation to acute myeloid leukemia. To date, only allogeneic stem cell transplantation has shown curative potential in MDS. The heterogeneous nature of MDS, and the paucity of randomized studies make individual therapeutic decisions, still largely based on the international prognostic scoring system, difficult. RECENT FINDINGS In lower-risk MDS, recent advances include demonstration of a possible survival advantage with erythropoiesis stimulating agents, the role of lenalidomide in cases with del 5q (which lead to its approval in the treatment of lower-risk MDS with del 5q by the Food and Drug Administration), and recognition of the importance of iron overload on prognosis. In higher-risk patients, progress has come from the use of reduced intensity conditioning allogeneic SCT in elderly patients, and from results obtained with the hypomethylating agents azacytidine and decitabine, leading to their approval for the treatment of symptomatic MDS by the Food and Drug Administration. In particular, results of a phase III trial show a significant survival benefit for azacytidine over conventional treatments in higher-risk MDS. This is the first time a drug demonstrates a survival impact in higher-risk MDS. SUMMARY We review these recent advances in this paper.

Abstract
High-risk neuroblastoma has a poor prognosis despite multimodal treatment including high-dose chemotherapy. A 7-year-old male with neuroblastoma received ex vivo-expanded donor CD4(+) T lymphocyte infusion (CD4(+) DLI) after recurrence in the bone marrow following allogeneic hematopoietic stem cell transplantation from his HLA-identical mother. The disease transiently responded to CD4(+) DLI with reduction of tumor cells and a decrease of serum neuron-specific enolase. The response was associated with development of continued high fever and an increase of cytotoxic T lymphocytes in peripheral blood. This case suggests a possibility of a graft-versus-tumor effect against neuroblastoma.

Abstract
The overall risk of infections is lower in patients undergoing non-myeloablative allogeneic stem cell transplantation (NST) than in conventional stem cell transplant recipients. We sought to evaluate conditions associated with increased risk of infections after NST. In 81 patients, 187 infection episodes were noted; chronic lymphocytic leukemia (138 episodes/100 person-years) and recipients of matched unrelated donor graft (128 episodes/100 person-years) had higher risk of infection. Only half of the cytomegalovirus (CMV) infections occurred 31-100 days after transplantation. Most patients with CMV infection were non-neutropenic (100%), had lymphoma (76%), were younger (<55 years; 72%) and had received matched related donor (MRD) graft (72%). However, graft-versus-host disease (GVHD) was present in only 15% of these patients. Seven (78%) of nine invasive fungal infections (IFI) were diagnosed >100 days after NST and were associated with high mortality (78%). Most patients with IFI were also not neutropenic (100%), had received MRD graft (100%), had lymphoma (78%) and were given systemic steroids (78%); unlike CMV infection, 67% of these patients also had GVHD. On the basis of our results, we propose that NST recipients with lymphoma treated with high-dose corticosteroids for GVHD be considered for antifungal prophylaxis or pre-emptive antifungal therapy.

Abstract
The role of graft-versus-malignancy reactivity in the effects of allogeneic hematopoietic stem cell transplantation and donor lymphocyte infusion (DLI) for myelodysplastic syndromes is as yet not well established. Clinical data are limited and animal models are scarce. Here, we report on the effects of allogeneic bone marrow transplantation (alloBMT) and DLI in a novel model of irradiation-induced murine myelodysplastic/myeloproliferation syndrome (MD/MPS). Total body irradiation with 8.5 Gy in SJL/J mice gave rise to a lethal wasting syndrome in 60% of mice, characterized by 1 degrees normocellular bone marrow with dysplastic features in erythroid, myeloid and megakaryocytic cell lineages, 2 degrees lymphosplenomegaly with spleens harboring a prominent extramedullary hematopoiesis with erythroid, myeloid and megakaryocytic lineages exhibiting dysplastic features, and foci of dysplastic hematomyelopoiesis in the liver, 3 degrees peripheral thrombocytopenia and 4 degrees evidence of disseminated infection or leukemic transformation in selected animals. This clinicopathological picture was consistent with a murine form of MD/MPS. Syngeneic or allogeneic (BALB/c) T cell-depleted BMT could not prevent the occurrence of lethal MD/MPS. In contrast, DLI at weeks 2-4 after BMT led to restoration of the dysbalanced hematomyelopoiesis. However, severe DLI-induced acute graft-versus-host disease occurred, precluding a survival advantage. We present evidence of the existence of a post-alloBMT DLI-induced graft-versus-MD/MPS effect in murine irradiation-induced MD/MPS.

Abstract
PURPOSE Patients with metastatic or recurrent Ewing's sarcoma family of tumors and alveolar rhabdomyosarcoma have <25% 5-year survival in most studies. This study administered a novel immunotherapy regimen aimed at consolidating remission in these patients. EXPERIMENTAL DESIGN Fifty-two patients with translocation positive, recurrent, or metastatic Ewing's sarcoma family of tumors or alveolar rhabdomyosarcoma underwent prechemotherapy cell harvest via apheresis for potential receipt of immunotherapy. Following completion of standard multimodal therapy, 30 patients ultimately initiated immunotherapy and were sequentially assigned to three cohorts. All cohorts received autologous T cells, influenza vaccinations, and dendritic cells pulsed with peptides derived from tumor-specific translocation breakpoints and E7, a peptide known to bind HLA-A2. Cohort 1 received moderate-dose recombinant human interleukin-2 (rhIL-2), cohort 2 received low-dose rhIL-2, and cohort 3 did not receive rhIL-2. RESULTS All immunotherapy recipients generated influenza-specific immune responses, whereas immune responses to the translocation breakpoint peptides occurred in 39%, and only 25% of HLA-A2(+) patients developed E7-specific responses. Toxicity was minimal. Intention-to-treat analysis revealed a 31% 5-year overall survival for all patients apheresed (median potential follow-up 7.3 years) with a 43% 5-year overall survival for patients initiating immunotherapy. CONCLUSIONS Consolidative immunotherapy is a scientifically based and clinically practical approach for integrating immunotherapy into a multimodal regimen for chemoresponsive cancer. Patients receiving immunotherapy experienced minimal toxicity and favorable survival. The robust influenza immune responses observed suggest that postchemotherapy immune incompetence will not fundamentally limit this approach. Future studies will seek to increase efficacy by using more immunogenic antigens and more potent dendritic cells.

Abstract
Hematopoietic cell transplantation is used to treat malignancies, hematologic and immune deficiency states, marrow failure syndromes, and autoimmune diseases. Graft-versus-host disease (GVHD) is a clinical syndrome seen following allogeneic transplantation where donorderived immunocompetent T cells and inflammatory responses attack host tissues. GVHD can cause significant morbidity and even result in mortality. The oral cavity is a frequently involved site with clinical changes resembling autoimmune collagen vascular diseases. Recognition, diagnosis, and monitoring of oral GVHD can help with diagnosis and grading of GVHD and judging responses to therapy. Topical and local management of symptomatic oral GVHD can reduce oral symptoms that can interfere with oral function and quality of life, and can reduce the need for more intensive immunosuppressive systemic therapies.

Abstract
PURPOSE Reduced-intensity conditioning (RIC) for allogeneic stem-cell transplantation (allo-SCT) reduces nonrelapse mortality (NRM). This reduction makes it possible for patients who are ineligible for high-dose myeloablative conditioning allo-SCT to benefit from graft-versus-leukemia reaction. In this multicenter, prospective study of patients with acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (MDS), we investigated the efficacy of RIC allo-SCT from a human leukocyte antigen-identical sibling by using a regimen that uses fludarabine and busulfan. PATIENTS AND METHODS Ninety-three patients with AML (n = 59) and MDS (n = 34) were included, and the median age was of 53 years. Follow-up for survivors was 43 months (range, 3 to 89 months). The conditioning regimen consisted of fludarabine (150 mg/m(2)) and oral busulfan (8 to 10 mg/kg). All except one patient received mobilized peripheral blood stem cells. Graft-versus-host disease (GVHD) prophylaxis consisted of cyslosporine and methotrexate or mycophenolate mofetil. RESULTS The 100-day, 1-year, and 4-year incidences of NRM were 8, 16%, and 21%, respectively. The 1- and 4-year relapse cumulative incidences were 23% and 37%, respectively, and leukemia recurrence was the main cause of death. The 4-year disease-free survival (DFS) and overall survival (OS) rates were 43% and 45%, respectively. The 4-year cumulative incidence of chronic GVHD was 53% (45% extensive), and its development was the major factor associated with lower relapse incidence and improved DFS and OS. CONCLUSION Our results confirm the capacity of this RIC regimen to obtain long-term remissions in patients ineligible for a conventional allo-SCT. The results suggest an important role of the development of chronic GVHD in reducing relapse and improving DFS and OS.

Abstract
Allogeneic hematopoietic cell transplantation (HCT) represents a potentially curative approach for patients with myelodysplastic syndromes (MDSs). While a large proportion of HCT recipients become long-term disease-free survivors, recurrence of MDS remains the leading cause of mortality after HCT. The role of donor lymphocyte infusion (DLI) in patients with relapsed MDS after HCT is unclear. We report results among 16 patients treated with DLI for relapsed MDS after HCT at a single institution between March 1993 and February 2004. The cohort contained 10 men and 6 women with a median age of 49 (range, 22-67) years. CR with resolution of cytopenias and prior disease markers occurred in 3 of 14 patients who could be evaluated. Two patients survived without MDS for 68 and 65 months after DLI, respectively, but died with pneumonia. Grades II-IV acute GVHD and chronic GVHD occurred after DLI in 6 (43%) and 5 (36%) patients, respectively. All three responders developed grades III-IV acute GVHD and extensive chronic GVHD after DLI. Our results confirm prior reports that DLI can result in CR in some patients with recurrent MDS after transplant, but long-term survival is infrequent.

Abstract
This study compares children and adolescents with hematological malignancies undergoing allogeneic stem cell transplantation (ASCT) with unrelated donors receiving either bone marrow (BM, n=39) or peripheral blood stem cells (PBSCs, n=35). Age and other characteristics were comparable in the two groups. All patients were given conventional conditioning and antithymocyte globulin (ATG). Graft-versus-host disease prophylaxis consisted of cyclosporine plus methotrexate or prednisolone. After PBSC, engraftment of neutrophils and platelets were more rapid. The incidences of acute and chronic graft-versus-host disease were similar in the two groups. In the two groups, other outcome variables, such as transplant-related mortality, overall survival, and relapse-free survival, were the same. Patients given BM tended to have more relapses (P=0.1) and patients given PBSC tended to have more incidences of infectious death. Four cases of EBV-lymphomas were found among patients receiving PBSC, whereas no case was seen in patients given BM (P=0.1). We found no differences in transplant-related mortality and survival in children and adolescents receiving BM or PBSC from unrelated donors. More rapid engraftment and a trend for less relapses in patients given PBSC grafts was noted.

Abstract
The goal of allogeneic (allo)-hematopoietic stem-cell transplantation (HSCT) in the treatment of hematologic malignancies is to harness the graft-versus-leukemia (GVL) effect, while minimizing the risk of graft-versus-host disease (GVHD). Allo-HSCT research has focused on the GVL target antigens and effector mechanisms, and on potential approaches to exploit GVL independently of GVHD. Donor lymphocyte infusion (DLI) achieves the most powerful anti-leukemic responses, and this approach is often used in combination with nonmyeloablative transplant regimens to optimize GVL and reduce GVHD. Serial, dose-escalating, and CD8(+) T-cell-depleted DLI have been introduced into clinical practice, while other variants of DLI have so far been explored only in animal models. The role of naturally occurring regulatory T cells in transplantation tolerance is being increasingly acknowledged, and murine studies indicate the potential ability of T cells to regulate GVHD while maintaining GVL. Experimental and clinical studies have demonstrated the importance of host-type chimerism, particularly for antigen-presenting cells, in determining the occurrence of DLI-induced GVL. Murine studies could assist in the development of clinical strategies targeted at antigen-presenting cells. Clinical studies exploiting natural killer-cell-mediated antitumor reactivity in the context of killer inhibitory receptor-ligand-mismatched allo-HSCT have provided promising results.

Abstract
We studied the effect of CTLA-4 blockade on graft-versus-leukemia and graft-versus-host responses in a mouse model of minor histocompatibility-mismatched bone marrow transplantation. Early CTLA-4 blockade induced acute graft-versus-host disease. Delayed CTLA-4 blockade resulted in a lethal condition with lymphosplenomegaly, but with stable mixed T-cell chimerism, unchanged alloreactive T-cell frequencies and absent anti-host reactivity in vitro. In contrast, multiorgan lymphoproliferative disease with autoimmune hepatitis and circulating anti-DNA auto-antibodies were documented. Splenic lymphocytes exhibited ex vivo spontaneous proliferation and a marked proliferative response against host-type dendritic cells pulsed with syngeneic (host-type) tissue-peptides. Both phenomena were exclusively mediated by host and not donor T cells, supporting an autoimmune pathogenesis. Selectively host-derived T-cell immune reactivity was equally documented against leukemia-peptide-pulsed dendritic cells, and this was paralleled by a strong in vivo antileukemic effect in anti-CTLA-4-treated and subsequently leukemia-challenged chimeras. In conclusion, delayed CTLA-4 blockade induced a host-derived antileukemic effect, occurring in the context of an autoimmune syndrome and strictly separated from graft-versus-host disease. Both antileukemic and autoimmune responses depended on the allogeneic component, as neither effect was seen after syngeneic bone marrow transplantation. Our findings reveal the potential of using CTLA-4 blockade to establish antileukemic effects after allogeneic hematopoietic stem cell transplantation, provided autoimmunity can be controlled.

Abstract
Despite advances in the procedure and posttransplantation immunosuppressive therapy, more than half of allogeneic hematopoietic stem cell transplant (HSCT) recipients develop graft-versus-host disease (GVHD), which remains a major cause of morbidity and mortality. Modern HSCT protocols have resulted in substantial alterations in the timing and relative incidences of acute and chronic GVHD, making traditional classification schemes obsolete. This article reviews major changes in HSCT during the past decade, evolving concepts of acute and chronic GVHD (including new diagnostic criteria) and the expanding spectrum of cutaneous GVHD. It focuses on observations that have led to a better delineation of the full constellation of skin findings in chronic cutaneous GVHD, including lichen sclerosus, morpheaform lesions, and eosinophilic fasciitis. Recent insights into pathogenesis of GVHD, lessons from GVHD arising in settings outside HSCT, and therapeutic advances also are highlighted.

Abstract
Results of allogeneic hematopoietic stem cell transplantation (HCT) to treat advanced leukemia or myelodysplastic syndrome (MDS) remain poor due to excessive relapse and transplant-related mortality. To improve transplant outcome in this patient population, 43 patients (median age, 46.1 years) with high-risk or advanced lymphoid (n = 5) or myeloid malignancy (n = 38) were prospectively enrolled on a pilot trial of cytoreduction with intravenous busulfan and melphalan followed by an unmodified HLA-A, -B, and -DRbeta1-matched related (n = 18) or unrelated (n = 25) HCT. Graft-versus-host disease (GVHD) prophylaxis consisted of tacrolimus and methotrexate. Thirty-four patients had > or = 5% blasts at the time of HCT; 12 of these had > 20% blasts. Seventeen patients had unfavorable cytogenetics, 8 patients underwent transplantation for secondary MDS or acute myelogenous leukemia, and 4 patients had relapsed after a previous allogeneic transplantation. Although mucositis was the most significant regimen-related toxicity, requiring the addition of folinic acid rescue and failure to receive all 4 doses of methotrexate in 23 patients, the nonrelapse mortality at 30 and 100 days was low at 0% and 16%, respectively. The cumulative incidence of grade II-IV acute GVHD was 24%, and that of extensive chronic GVHD was 7%. With a minimum follow-up of 18 months, the estimated 3-year overall survival is 37% and the estimated disease-free survival (DFS) is 33%. For 18 patients with MDS (< or = RAEB-2) or high-risk myeloproliferative disorder, the estimated 3 year DFS is 61%. These data demonstrate the curative potential of this regimen in patients with high-risk myeloid malignancies.

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.
