Abstract
PURPOSE The poor immunogenicity of most leukemias and the lack of specificity of the donor T cells limit the in vivo effectiveness of conventional donor lymphocyte infusions in many patients suffering from persistent or recurrent leukemia after allogeneic stem cell transplantation. These limitations may be overcome by the adoptive transfer of in vitro generated leukemia-reactive T cells. Although the potential clinical efficacy of this approach has been shown previously, lack of reproducibility of the procedure and the inability to show persistence and survival of the transferred T cells hampered further clinical application. The purpose of this study was to develop a new, broadly applicable strategy for the efficient generation and isolation of leukemia-reactive T cells with a better probability to survive and expand in vivo. EXPERIMENTAL DESIGN Myeloid and B-cell leukemias were modified into professional immunogenic antigen-presenting cells, and used to stimulate HLA-matched donor T cells. After two stimulations, responding donor T cells were isolated based on their secretion of IFN-gamma and tested for their capacity to recognize and kill the primary leukemia. RESULTS Using one universal stimulation and isolation protocol for various forms of leukemia, T-cell populations containing high frequencies of leukemia-reactive T cells could reproducibly be generated and early isolated under mild stimulatory conditions. Isolated T cells still had high proliferative potential and their reactivity seemed to be restricted to cells of the patient's hematopoiesis. CONCLUSION We here show a new robust procedure for the generation and isolation of leukemia-reactive T cells for adoptive transfer.

Abstract
Resistance of leukemic cells to chemotherapy frequently occurs in patients with acute leukemia, which may be caused by alterations in common apoptotic pathways. Controversy exists whether cytostatic agents induce the mitochondrial or death receptor pathway of apoptosis. In the mitochondrial pathway cytochrome C release and caspase-9 activation play a central role in the induction of apoptosis, while formation of a Death Inducing Signaling Complex (DISC) and caspase-8 activation have been reported to be essential in death receptor-induced apoptosis. Here, we show in human derived myeloid and lymphoblastic leukemia cell lines that caspase-8 plays a more important role than previously expected in apoptosis mediated via the mitochondrial pathway. We demonstrated in these malignant cells chemotherapy-induced apoptosis independent of the death receptor pathway, since blocking this pathway using a retroviral construct encoding Flice inhibitory protein (FLIP) did not inhibit drug-induced apoptosis or caspase-8 activation, while overexpression of Bcl-2 completely inhibited both events. Furthermore, we showed that activation of caspase-8 by cytostatic agents occurred downstream from mitochondria. Since caspase-8 plays a central role in both death receptor- and chemotherapy-induced apoptosis of malignant cells from patients with acute leukemia, therapeutic strategies focusing at modulation and activation of caspase-8 may be successful in the treatment of drug-resistant malignancies.

Abstract
Minor histocompatibility antigens (mHags) play an important role in both graft-versus-tumor effects and graft-versus-host disease (GVHD) after allogeneic stem cell transplantation. We applied biochemical techniques and mass spectrometry to identify the peptide recognized by a dominant tumor-reactive donor T-cell reactivity isolated from a patient with relapsed multiple myeloma who underwent transplantation and entered complete remission after donor lymphocyte infusion. A frequently occurring single nucleotide polymorphism in the human ATP-dependent interferon-responsive (ADIR) gene was found to encode the epitope we designated LB-ADIR-1F. Although gene expression could be found in cells from hematopoietic as well as nonhematopoietic tissues, the patient suffered from only mild acute GVHD despite high percentages of circulating LB-ADIR-1F–specific T cells. Differential recognition of nonhematopoietic cell types and resting hematopoietic cells as compared with activated B cells, T cells, and tumor cells was demonstrated, illustrating variable LB-ADIR-1F expression depending on the cellular activation state. In conclusion, the novel mHag LB-ADIR-1F may be a suitable target for cellular immunotherapy when applied under controlled circumstances.

Abstract
Although donor lymphocyte infusion (DLI) induces complete remissions in 70% of patients with relapsed chronic myeloid leukemia (CML) after allogeneic stem-cell transplantation (SCT), some patients are refractory to DLI by showing disease persistence. In a patient who received DLI for relapsed CML, we observed persisting molecular disease despite a hematological and cytogenetic remission in the absence of graft-versus-host disease (GVHD). To determine the nature of this immune response, we isolated leukemia-reactive donor T-cell clones from the bone marrow (BM) of the patient at the time of clinical response. Four different types of CD8+ HLA class I restricted T-cell clones were obtained that were cytotoxic against Ebstein-Barr virus-transformed B-cell lines (EBV-LCL) of the patient, but not the donor, indicating recognition of minor histocompatibility antigens (mHags). By using survival studies with CFSE labelled BM cells populations, a hematopoietic progenitor cell inhibition assay and direct morphological examination we showed that the T-cell clones recognized mature monocytic and myeloid cells, whereas immature BM progenitor cells were insufficiently lysed. This patient's refractoriness for DLI appears to be caused by inadequate lysis of progenitor cells by these cytotoxic T cells. These findings support the hypothesis that for eradication of CML a cytotoxic T-cell response against leukemic progenitor cells is essential.

Abstract
Characterization of the antigens recognized by tumor-reactive T cells isolated from patients successfully treated with allogeneic HLA-matched hematopoietic stem cell transplantation (SCT) can lead to the identification of clinically relevant target molecules. We isolated tumor-reactive cytotoxic CD8(+) T-cell (CTL) clones from a patient successfully treated with donor lymphocyte infusion for relapsed multiple myeloma after allogeneic HLA-matched SCT. Using cDNA expression cloning, the target molecule of an HLA-B7-restricted CTL clone was identified. The CTL clone recognized a minor histocompatibility antigen produced by a single nucleotide polymorphism (SNP) in the angiogenic endothelial-cell growth factor-1 (ECGF1) gene also known as thymidine phosphorylase. The SNP leads to an Arg-to-His substitution in an alternatively translated peptide that is recognized by the CTL. The ECGF1 gene is predominantly expressed in hematopoietic cells, although low expression can also be detected in other tissues. The patient from whom this CTL clone was isolated had mild graft-versus-host disease despite high numbers of circulating ECGF-1-specific T cells as detected by tetramer staining. Because solid tumors expressing ECGF-1 could also be lysed by the CTL, ECGF-1 is an interesting target for immunotherapy of both hematologic and solid tumors.

Abstract
Gemtuzumab ozogamicin (GO) is a recently developed antibody-targeted chemotherapeutic agent and has been expected to be less toxic than conventional chemotherapy. We retrospectively evaluated the use of GO in 38 patients. Patients with acute myeloid leukemia (AML) at diagnosis and relapsed AML were treated with 6 and 9 mg/m(2) GO. Efficacy and toxicity of GO were analyzed, as well as several prognostic factors. A complete response (CR) was observed in 12 of 38 patients, including five patients with CR plus incomplete regeneration of platelets. In one patient a partial remission was observed. Twenty-five patients showed no change or progressive disease. The overall response (OR) in patients with AML at diagnosis was 47%, with the best response in patients with primary AML (OR 60%, compared with 21% OR in non-primary AML, P = 0.045). The OR in patients with relapsed AML was 22%. Median white blood cell (WBC) before treatment, CD33 expression on leukemic blasts, and kinetics of response were analyzed as prognostic factors. Median WBC was significantly lower in patients who responded to GO, compared with non-responders (2.1 x 10(9)/L vs. 6.8 x 10(9)/L, P = 0.036). CD33 expression and kinetics of response was not correlated to clinical outcome. Median days to reach 500 x 10(6)/L neutrophils and 100 x 10(9)/L platelets were 36 and 39 d, respectively. Infections and bleedings occurred in 45% and 12%, respectively. This report shows that GO has potent clinical activity and that the OR rate was by far the best in untreated primary AML patients.

Abstract
PURPOSE In patients treated with allogeneic stem cell transplantation for advanced mantle cell lymphoma (MCL), complete sustained remissions have been observed illustrating susceptibility of MCL cells to a graft-versus-lymphoma effect. To potentiate this graft-versus-lymphoma effect, adoptive transfer of in vitro selected MCL-specific CTL can be an attractive approach. The lack of expression of costimulatory molecules on MCL cells hampers the generation of MCL-reactive T-cell responses. The purpose of this study was to modify MCL cells into antigen-presenting cells (APC) and to use these MCL-APCs to induce allogeneic MCL-reactive T-cell responses. EXPERIMENTAL DESIGN Interleukin (IL)-4, IL-10, CpG, and CD40 activation were tested for their capacity to up-regulate costimulatory molecules on MCL cells. Primary MCL cells or the modified MCL-APCs were then used to evaluate the induction of MCL-reactive T-cell responses in HLA-matched donors. RESULTS Ligation of CD40 on MCL cells was essential to up-regulate costimulatory molecules and to induce production of high amounts of IL-12. In contrast to primary MCL cells, MCL-APC cells as stimulators were capable of inducing CD8+ CTL lines from HLA class I-matched donors. High numbers of CTL clones could be generated capable of efficiently killing the primary MCL cells and MCL-APC but not donor-specific targets. CONCLUSION These results show the feasibility to generate primary allogeneic T-cell responses against MCL-APC, and may provide new immunotherapeutic tools to further exploit the graft-versus-lymphoma effect following allogeneic stem cell transplantation in patients with MCL.

Abstract
Gemtuzumab ozogamicin (Mylotarg) induces remission in approximately 30% of relapsed AML patients. We previously demonstrated that gemtuzumab infusion results in near-complete CD33 saturation in peripheral blood, and that saturating gemtuzumab levels result in continuous binding and internalization of gemtuzumab due to renewed CD33 expression. We now demonstrate that a high CD33-antigen load in peripheral blood is an independent adverse prognostic factor, likely due to peripheral consumption of gemtuzumab. Indeed, CD33 saturation in bone marrow is significantly reduced (40-90% saturation) as compared with CD33 saturation in corresponding peripheral blood samples (>90%). In vitro, such reduced CD33 saturation levels were strongly related with reduced cell kill. Apparently, high CD33-antigen loads in blood consume gemtuzumab and thereby limit its penetration into bone marrow. Consequently, CD33 saturation in bone marrow is reduced, which hampers efficient cell kill. Therefore, gemtuzumab should be administered at higher or repeated doses, or, preferably, after reduction of the leukemic cell burden by classical chemotherapy.

Abstract
OBJECTIVE Unresponsiveness to chemotherapy is a major problem in the treatment of leukemia, which can be caused by unresponsiveness of noncycling cells to cell cycle-dependent cytotoxic agents. Targeted toxins consisting of a targeting and activating cytokine (granulocyte-macrophage colony-stimulating factor [GM-CSF]) and diphtheria toxin (DT) can be used to overcome this kind of resistance of leukemic cells. In this study we manipulated the cell cycle and proliferative status of leukemic cells, explored the effect on sensitivity to DT, and determined the ability of DT388GMCSF fusion proteins to activate and subsequently kill leukemic cells. MATERIALS AND METHODS We used the GM-CSF-dependent myeloid leukemic cell line AML-193 as a model. GM-CSF or granulocyte colony-stimulating factor (G-CSF) was used to manipulate the cell cycle and proliferative state of AML-193 cells. Cell death was quantified by 51Cr release assays. The results obtained in the AML-193 cell line model were confirmed using primary leukemic blasts. RESULTS Similar to treatment with chemotherapy and immunotherapy, leukemic cells in resting G0 phase were relatively resistant to DT-induced cell death. Synchronized recruitment of leukemic cells into activated phases of the cell cycle by low concentrations of GM-CSF or G-CSF resulted in significant increased DT sensitivity. DT388GMCSF fusion proteins specifically targeted GM-CSF receptor-expressing cells, resulting in recruitment of leukemic cells from G0 phase of the cell cycle and subsequent kill of these cells. CONCLUSION Leukemic cells in G0 phase, which are resistant to conventional chemotherapy, Fas-induced immunotherapy, and DT alone, can be synchronically activated and subsequently killed by DT388GMCSF fusion proteins.

Abstract
Multicenter phase II trials with Gemtuzumab Ozogamicin (GO/Mylotarg), consisting of a CD33 antibody linked to the cytotoxic drug calicheamicin, have shown a 30% overall response rate in relapsed acute myeloid leukemia patients. However, no clear correlation was observed between CD33 expression on leukemic blasts and response to GO therapy. We analyzed the CD33 specificity of GO-induced cell death and the effect of GO on CD33-negative malignancies. We demonstrate that lysis induced by clinically relevant GO concentrations is partially CD33 mediated, and that efficient non-CD33-mediated GO uptake can occur via endocytosis. In agreement with these results, we observed GO-mediated death of human CD33-negative acute lymphoblastic leukemia cells both in vitro and in vivo in an NOD/SCID mouse model. Finally, sensitivity to GO-induced cell death was at least partially determined by the activation status of leukemic cells, with cells in activated phases of the cell cycle being most effective in both CD33-specific GO internalization, renewed expression of CD33 molecules, and non-CD33-mediated GO uptake via endocytosis. In conclusion, these data provide mechanistic insight into the efficacy of GO in CD33-positive as well as in CD33-negative malignancies with endocytic capacity, and provide a rationale for the use of GO in the treatment of malignancies with endocytic capacity.

Abstract
For the clinical evaluation of the efficacy of cellular immunotherapy it is necessary to analyze the effector functions of T cells against primary leukemic target cell populations which are usually considerably heterogeneous caused by differential maturation stages of the leukemic cells. An appropriate assay should not only allow the quantitative analysis of rapid cell death induction as measured by the conventional 51Cr release assay but also of the more slowly executing pathways of T-cell-induced apoptosis occurring within days instead of hours which cannot be measured using this method. Furthermore, it should dissect the differential susceptibility to T-cell-induced cell death of various target cell subpopulations and characterize the malignant precursor cells capable of producing malignant progeny. To fulfill these requirements we developed a new assay based on carboxyfluorescein diacetate succinimidyl ester (CFSE) labeling of the target cell population combined with antibody staining of specific cell populations and addition of fluorescent microbeads to quantitatively monitor target cell death occurring within a longer time frame up to at least 5 days. This new assay facilitates the analysis of differential recognition of distinct cell types within a heterogeneous target cell population and allows simultaneously evaluation of the proliferative status of surviving target cells in response to relevant cytokines.

Abstract
In this study, we analyzed the influence of cell cycle status manipulations of leukemic cells on Fas-mediated apoptosis using the GM-CSF-dependent human myeloid leukemia cell line AML-193 as a model. GM-CSF and long-term treatment with interferon-gamma (IFN-gamma) or interferon-alpha (IFN-alpha) were used to manipulate the cell cycle status. Control cells were GM-CSF deprived, nonproliferating cells. IFN-gamma or IFN-alpha treatment did not induce proliferation in control cells, but resulted in recruitment of cells from resting G(0) phase into activated G(1) phase. Using agonistic anti-Fas antibodies (FAS18), we demonstrated that this shift from G(0) to G(1) was accompanied by a 2.5-fold increase in Fas sensitivity. A similar increase in sensitivity to FAS18 could be obtained by induction of proliferation with GM-CSF. Quantitative FACS analysis of surviving cells after FAS18-induced apoptosis showed deletion of the G(1) compartment, but complete protection of resting G(0) cells. Cells in S or G(2)/M phase were relatively protected against Fas induction. In conclusion, sensitivity to Fas-mediated apoptosis was restricted to cells in G(1) phase of the cell cycle, and can be increased by treatment of cells with interferons. By this mechanism, interferon treatment may render leukemic cells more susceptible to lysis by T cells during immunotherapeutic interventions.

Abstract
The expression of adhesion and co-stimulatory molecules, and chemokine and death receptors such as tumour necrosis factor (TNF) and FAS on acute myeloid leukaemia (AML) may influence the biology of the disease and response to chemotherapy and immunotherapy. In this study, we analysed the expression of these molecules in 99 AML patients using monoclonal antibodies and flow cytometry, and correlated the expression with French-American-British (FAB) classification and survival. The following molecules were studied: the co-stimulatory molecules CD80, CD86 and CD40; the adhesion molecules CD11a-c, CD31, CD43, CD50, CD54, CD102, CD58 and CD62L; the chemokine receptor CXCR4; and the death receptors TNFR1 and TNFR2 and FAS. The expression of all molecules was significantly higher in the M4/M5 FAB subgroups except for CD80, CD43, CD54 and CD62L. The AML M3 subgroup had a significant lower expression of CD11a (P = 0.02) and CD11c (P = 0.03). Five-year survival was significantly shorter in cases of high CD40 expression [> 20% positive cells, relative risk (RR) 2.56, P = 0.02] or high CD11a expression (> 80% positive cells, RR 2.6, P = 0.03). This effect was most prominently present in the AML M4/M5 FAB subgroups. We conclude that the expression levels of adhesion and co-stimulatory molecules, CXCR4 and apoptosis-receptors are predominantly FAB subtype-related with high CD40 and CD11a expression as poor prognostic factors.

Abstract
We have identified 79 mutations in BRCA1 in a set of 643 Dutch and 23 Belgian hereditary breast and ovarian cancer families collected either for research or for clinical diagnostic purposes. Twenty-eight distinct mutations have been observed, 18 of them not previously reported and 12 of them occurring more than once. Most conspicuously, a 2804delAA mutation has been found 19 times and has never been reported outside the Netherlands. A common haplotype spanning > or = 375 kb could be identified for each of the nine examined recurrent mutations, indicating the presence of multiple BRCA1 founder mutations in the Dutch population. The 2804delAA mutation has been estimated to have originated approximately 32 generations ago. No specific breast or ovarian cancer phenotype could be assigned to any of the common mutations, and the ovarian cancer incidence among 18 families with the 2804delAA mutation was heterogeneous.
