Abstract
Stem cell transplantation (SCT) constitutes a major challenge to the immune system. Long-term impairment of immunity against various common infectious stimuli leads to increased susceptibility to infectious diseases; in contrast, an immune response against the recipient may cause the devastating graft-versus-host disease (GvHD). Recovery of the immune system (both qualitative and quantitative) after SCT is perhaps the most important factor in determining the clinical outcome. Consequently, immune reconstitution has been extensively studied using different approaches, including quantitative analysis of immune cells as well as their phenotypic characterization. Analysis of diversity and clonality is an important tool in determining competence of the immune system, assuming that a broad diversity assures efficient response to different stimuli and clonal dominance reflects ongoing, potentially relevant immune responses. Detailed analysis of the immune repertoire through the flow cytometric and molecular study of the T cell receptor repertoire has been applied to gain quantitative and qualitative insights about the T cell immune competence and responsiveness. After SCT, a contraction of the T cell pool and a reduction in T cell receptor diversity is clearly associated with clinical immunodeficiency. Reconstitution of the immune system is often characterized by dominance of oligoclonal T cell populations, reflecting specific antigen-driven immune responses. Detailed characterization of T lymphocytes by T cell receptor analysis is possible, and may lead to the identification of individual clones involved in specific immune reactions, such as alloresponses in GvHD, the closely related graft-versus-leukemia effect and opportunistic viral agents such as CMV or EBV.

Abstract
Allogeneic hematopoietic stem cell transplantation provides curative therapy for some patients with advanced hematologic malignancies. Disease response after allogeneic transplant is, at least in part, mediated by donor immune cells. In this report we describe a cellular therapy using haploidentical peripheral blood stem cells administered after very low dose total body irradiation (TBI) (100cGy). The donor cells were anticipated to be rejected, so no graft-versus-host (GVHD) prophylaxis was used. Patients with persistent disease beyond 8 weeks could be further treated with infusions of irradiated haploidentical donor cells. Of the 10 patients enrolled in the study, durable engraftment of allogeneic cells was seen in one patient. Two patients with resistant relapsed acute myelogenous leukemia (AML) had a disease response. Analysis of T cell reactivity from one patient who achieved a complete response but did not have durable engraftment of donor cells indicated that disease response was associated with the generation of host-derived anti-leukemic cytotoxic CD8+ T cells that reacted with an AML-associated proteinase 3 epitope. Results from this patient suggest that allogeneic therapy induced a host anti-tumor response associated with cytotoxic T cells reactive with a low affinity self-antigen.

Abstract
Direct comparisons of human (h) and murine (m) neutrophil elastase (NE) and proteinase 3 (PR3) are important for the understanding and interpretation of inflammatory and PR3-related autoimmune processes investigated in wild-type-, mNE- and mPR3/mNE knockout mice. To this end, we purified recombinant mPR3 and mNE expressed in HMC1 and 293 cells and compared their biophysical properties, proteolytic activities and susceptibility to inhibitors with those of their human homologues, hPR3 and hNE. Significant species differences in physico-chemical properties, substrate specificities and enzyme kinetics towards synthetic peptide substrates, oxidized insulin B chain, and fibrinogen were detected. MeOSuc-AAPV-pNA and Suc-AAPV-pNA were hydrolyzed more efficiently by mPR3 than hPR3, but enzymatic activities of mNE and hNE were very similar. Fibrinogen was cleaved much more efficiently by mPR3 than by hPR3. All four proteases were inhibited by alpha(1)-antitrypsin and elafin. Eglin C inihibited mNE, hNE, mPR3, but not hPR3. SLPI inhibited both NEs, but neither PR3. The custom-designed hNE inhibitor, Val(15)-aprotinin, is a poor inhibitor for mNE. In conclusion, appropriate interpretation of experiments in murine models requires individual species-specific assessment of neutrophil protease function and inhibition.

Abstract
Anaplastic lymphoma kinase (ALK)-positive anaplastic large cell lymphoma (ALCL) has a good prognosis compared to ALK-negative ALCL, possibly as a result of the immune recognition of the ALK proteins. The aim of our study was to investigate the presence of both a B and cytotoxic T cell (CTL) response to ALK in ALK-positive ALCL. We confirmed the presence of an antibody response to ALK in all 9 ALK-positive ALCL patients investigated. An ELISpot assay was used to detect a gamma-interferon (IFN) T cell response after short term culture of mononuclear blood cells with 2 ALK-derived HLA-A*0201 restricted peptides: ALKa and ALKb. A significant gamma-IFN response was identified in all 7 HLA-A*0201-positive ALK-positive ALCL patients but not in ALK-negative ALCL patients (n = 2) or normal subjects (n = 6). CTL lines (>95% CD8-positive) raised from 2 ALK-positive ALCL patients lysed ALK-positive ALCL derived cell lines in a MHC-Class I restricted manner. This is the first report of both a B cell and CTL response to ALK in patients with ALK-positive ALCL. This response persisted during long-term remission. The use of modified vaccinia virus Ankara (MVA) to express ALK is also described. Our findings are of potential prognostic value and open up therapeutic options for those ALK-positive patients who do not respond to conventional treatment.

Abstract
Induction of donor type chimerism in mildly prepared hosts without graft-versus-host disease (GvHD) is a most desirable goal in bone morrow transplantation. We have recently demonstrated in a mouse model that donor veto cytotoxic T lymphocytes (CTLs) can facilitate the induction of donor type chimerism in sublethally irradiated recipients without causing GvHD if they are effectively depleted of alloreactivity against host cells by means of stimulation against a third party. We extend this approach to human cells, by preparing CTLs in two major steps: primary culture in the absence of interleukin 2, leading to death by neglect of antihost clones, and addition of interleukin 2 and subsequent dilution of antihost clones as a consequence of the expansion of the anti-third-party clones. CTLs prepared in this way specifically suppress host cytotoxic T cells directed against antigens of the donor, but not against fourth-party antigens, as demonstrated in a standard (51)Cr release assay. We conclude that human anti-third-party CTLs afford a new source of veto cells that are depleted of potential graft-versus-host-reactive clones. The cells generated by this approach could potentially be used to facilitate engraftment of allogeneic hematopoietic stem cells.

Abstract
A 22-year-old man with chronic myeloid leukemia (CML) received fractionated total body irradiation (TBI) (1440cGy) and etoposide (60 mg/kg) followed by infusion of 10 x 10(6) /kg CD34+ selected stem cells from his mother. Donor and recipient were 50% matched at the HLA-A and -B loci and 100% at HLA-DR. Mixed lymphocyte culture reaction was negative. Post-stem cell transplant (SCT) immunosuppression consisted of antithymocyte globulin, cyclosporine, and prednisone, and was discontinued after 7 months. The donor graft was rejected 2 years post-SCT. At 7 years post-SCT, he is clinically well with normal blood counts and no evidence of CML or myelodysplasia despite the presence over 6 years of multiple clones with balanced translocations and deletions in host bone marrow cells. The emergence of clonal hematopoiesis may provide insights into therapy-related leukemogenesis.

Abstract
Human neutrophil elastase (HNE) and proteinase 3 (PRO3) are myeloid tissue-restricted serine proteases, aberrantly expressed by myeloid leukemia cells. PRO3 and HNE share the PR1 peptide sequence that induces HLA-A*0201-restricted cytotoxic T cells (CTLs) with antileukemia reactivity. We studied the entire HNE protein for its ability to induce CTLs. In an 18-hour culture, HNE-loaded monocytes stimulated significant intracellular interferon gamma (IFN-gamma) production by CD4+ and CD8+ T cells in 12 of 20 and 8 of 20 healthy individuals, respectively. Lymphocytes from 2 HNE responders were pulsed weekly for 4 weeks to generate HNE-specific CTLs. One of 2 HLA-A*0201-negative individuals inhibited the colony formation of HLA-identical chronic myelogenous leukemia progenitor cells (73% inhibition at 50:1 effector-target [E/T] ratio), indicating that peptides other than PR1 can induce leukemia-reactive CTLs. Repetitive stimulations with HNE in 2 of 5 HLA-A*0201+ individuals increased PR1 tetramer-positive CD8+ T-cell frequencies from 0.1% to 0.29% and 0.02% to 0.55%, respectively. These CTLs recognized PR1 peptide or killed HNE-loaded targets. These results indicate that exogenously processed HNE is a source of PR1 peptide as well as other peptide sequences capable of inducing leukemia-specific CD8+ and CD4+ T cells. HNE could, therefore, be used in an HLA-unrestricted manner to induce leukemia-reactive CTLs for adoptive immunotherapy.

Abstract
Several bone marrow cells and lymphocyte subpopulations, known as "veto cells," were shown to induce transplantation tolerance across major histocompatibility antigens. Some of the most potent veto cells are of T-cell origin, and in particular a very strong veto activity was documented for cytotoxic T-lymphocyte (CTL) lines or clones. However, these cells also possess marked graft-versus-host (GVH) reactivity. In the present study we evaluated a new approach to deplete CTLs of antihost clones by stimulating the donor T cells against third-party stimulators in the absence of exogenous interleukin 2 (IL-2). We demonstrate that such CTLs are depleted of GVH reactivity while maintaining marked veto activity in vitro. Furthermore, marked synergism was exhibited between the veto CTLs and rapamycin when tested in a murine model, which measures T-cell-mediated bone marrow allograft rejection, or in sublethally irradiated allogeneic hosts. Our results suggest that engraftment of early progenitors could be enhanced by using host-nonreactive anti-third-party CTLs, in conjunction with nonmyeloablative rapamycin-based conditioning protocols, thereby significantly reducing the toxicity of allogeneic transplantation.
