Abstract
Tumor vaccines are being explored as a means of generating antitumor immune responses in patients with cancer. Based on the efficacy of allogeneic transplantation, acute myelogenous leukemia appears to be susceptible to cellular immune-based therapy. Dendritic cells (DCs) are the most potent antigen-presenting cells and, as such, are being studied as a platform for the design of cancer vaccines. In acute leukemia, a promising approach involves the generation of DCs from leukemic blasts via cytokine exposure ex vivo. Leukemia-derived DCs potentially retain the tumor-associated antigens of the leukemic clone, which are presented in the context of the immune stimulating machinery of the mature DC. However, the efficacy of this approach may be limited by intrinsic abnormalities in the malignant clone that prevent differentiation towards a normal DC phenotype.

Abstract
Immunotherapy for leukaemia patients, aiming at the generation of anti-leukaemic T cell responses, could provide a new therapeutic approach to eliminate minimal residual disease (MRD) cells in acute myeloid leukaemia (AML). Leukaemic blasts harbour several ways to escape the immune system including deficient MHC class II expression, low levels of co-stimulatory molecules and suppressive cytokines. Therapeutic vaccination with dendritic cells (DC) is now recognized as an important investigational therapy. Due to their unique antigen presenting capacity, immunosuppressive features of the leukaemic blasts can be circumvented. DC can be successfully cultured from leukaemic blasts in 60-70% of patients and show functional potential in vivo. Alternatively, monocyte derived DC obtained at time of complete remission loaded with leukaemia-specific antigens can be used as vaccine. Several sources of leukaemia-associated antigen and different methods of loading antigen onto DC have been used in an attempt to optimize antitumour responses including apoptotic cells, necrotic cell lysates and tumour-associated pep-tides. Currently, the AML-derived cell line MUTZ-3, an immortalized equivalent of CD34(+) DC precursor cells, is under investigation for vaccination purposes. For effective DC vaccination the intrinsic tolerant state of the patient must be overcome. Therefore, the development of efficient and safe adjuvants in antigen specific immunotherapeutic programs should be encouraged.

Abstract
Sequentially treating human melanoma cell lines by priming with interferon-gamma before adding interferon-beta was previously found to be the most efficient protocol for producing concurrently increased expression of the three surface antigens B7-1, intercellular adhesion molecule-1 and human histocompatibility leucocyte antigens Class I. The present study describes similar outcomes when the same sequential intercellular adhesion molecule-based protocol is applied to murine B16-F10 melanoma cells as well as preclinical studies using the B16-F10 model as a poorly immunogenic melanoma. Thus, treating B16-F10 cells or a highly expressing B7-1 transfected subline (B16-F10/B7-1 hi) by priming with interferon-gamma for 24 h before adding interferon-beta for a further 48 h (interferon-gamma 72/beta 48) increased expression of all three surface antigens, particularly major histocompatibility complex class I whose increased expression was sustained for several days. As a whole tumour cell vaccine, interferon-gamma 72/beta 48 treated B16-F10 cells produced greater levels of cytoxic T lymphocyte response compared to vaccines prepared from cells treated with a single type of interferon. Furthermore, B16-F10 cells expressing high levels of B7-1 and treated using the interferon-gamma 72/beta 48 protocol (interferon-gamma 72/beta 48-treated B16-F10/B7-1 hi) produced substantially increased cytoxic T lymphocyte responses with a fivefold greater synergy than the combined results of either interferon treated or B7-1 expressing cells tested individually. The resulting CD8+ cytoxic T lymphocyte showed greater specificity for B16-F10 cells with tenfold higher killing than for syngeneic EL-4 lymphoma cells. Killing proceeded via the perforin-mediated pathway. CTL responses were induced independent of CD4+ T helper cells. The majority of mice receiving interferon-gamma 72/beta 48-treated B16-F10/B7-1 hi vaccine in vivo remained tumour free after challenge with 5 x 105 live B16-F10 cells expressing intermediate B7-1 levels. The novel strategy described will help enhance vaccine potency when applied clinically to prepare whole cell based cancer vaccine therapies.

Abstract
Cytotoxic T cells directed against leukemic blasts have been observed in patients with acute myeloid leukemia (AML). However, generation of efficient T-cell responses is hampered due to several factors that enable AML blasts to protect themselves from the patients immune system. Improved immune responses can be established by the differentiation of AML blasts into AML-derived dendritic cells (DC) thereby conserving their intrinsic leukemia specific antigens and obtaining full capacity to present these antigens to naive T cells. This review discusses increased immunogenicity of AML blasts by differentiation into AML-DC and describes ways to augment the AML-DC vaccination approach.

Abstract
Combined expression of costimulatory factors and proinflammatory cytokines stimulate effective immune-mediated tumor rejection in a variety of murine tumor models. Specifically, syngeneic tumor cells genetically modified to express B7.1 (CD80) have been shown to induce rejection of previously established murine solid tumors, and transduction with IL-2 can further increase survival. However, poor rates of gene transfer and inefficient expression of multiple transgenes encoded by single vectors have hampered the development of such autologous tumor cell vaccines for clinical trials in acute myeloid leukemia (AML) patients. Here we describe the development of a self-inactivating lentiviral vector encoding B7.1 and IL-2 as a single fusion protein postsynthetically cleaved to generate biologically active membrane-anchored B7.1 and secreted IL-2. This enables the efficient transduction of both established and primary AML blasts, resulting in expression of the transgenes in up to 98% of the cells following a single round of infection at an m.o.i. of 10. The combined expression of IL-2 and B7.1 in AML blasts enables increased stimulation of both allogeneic and autologous T cells. The stimulated lymphocytes secrete greater levels of Th1 cytokines and show evidence of specificity, as indicated by their increased proliferation in the presence of autologous AML compared to remission bone marrow cells.

Abstract
Adjuvant treatment is still only working in a small percentage of breast cancer patients. Therefore, new strategies need to be developed. Immunotherapies are a very promising approach because they could successfully attack tumor cells in the stage of dormancy. To assess the feasibility of using an allogeneic approach for vaccination of breast cancer patients, we selected a CD80-transfected breast cancer cell line based on its immunogenic properties. Using CD80+ KS breast cancer cells and human leukocyte antigen (HLA)-A*02-matched peripheral blood mononuclear cells (PBMCs) of breast cancer patients in allogeneic mixed lymphocyte-tumor cell cultures (MLTCs), it was possible to isolate HLA-A*02-restricted cytotoxic T cells (CTLs). Furthermore, a genetically modified KS variant expressing influenza A matrix protein serving as a surrogate tumor-associated antigen (TAA) was able to stimulate flu peptide-specific T cells alongside the induction of alloresponses in MLTCs. KS breast cancer cells were demonstrated to express already known TAAs such as CEA, MUC-1, MAGE-1, MAGE-2, and MAGE-3. To further improve antigenicity, HER-2/neu was added to this panel as a marker antigen known to elicit HLA-A*02-restricted CTLs in patients with breast cancer. Thus, the antigen-processing and antigen-presentation capacity of KS cells was further demonstrated by the stimulation of HER-2/neu-specific CD8+ T cells in PBMCs of breast cancer patients in vitro. These results gave a good rationale for a phase I/II trial, where the CD80+ HER-2/neu-overexpressing KS variant is actually used as a cellular vaccine in patients with metastatic breast cancer. As a proof of principle, we present data from two patients where a significant increase of interferon-gamma (IFN-gamma) release was detected when postvaccination PBMCs were stimulated by allogeneic vaccine cells as well as by HLA-A*02-restricted HER-2/neu epitopes. In whole cell vaccine trials, monitoring is particularly challenging because of strong alloresponses and limited knowledge of TAAs. In this study, a panel of HER-2/neu epitopes, together with the quantitative real time (qRT)-PCR method to analyze vaccine-induced cytokines secreted by T cells, proved to be highly sensitive and feasible to perform an "immunological staging" following vaccination.

Abstract
BACKGROUND Pre-B ALL cells generally elicit a weak immune host response, due to poor expression of co-stimulatory molecules and/or suppression of immune function. A possible way to enhance immunogenicity of pre-B ALL cells is to convert them to DC-like cells. METHODS To study the effect of ALL cells on T-cell function, ALL cells were incubated with T adult cells activated by OKT3 MAb. Liquid culture of de novo pre-B ALL cells for 7 days, in a medium containing IL-1alpha, IL-3, IL-7, Flt 3 ligand (L) and tumor-necrosis factor alpha (TNF-alpha) produced DC-like cells. These were evaluated for morphology, viability, phenotype, as measured by flow cytometry, and function, including MLR. RESULTS Pre-B ALL cell-lines NALM-6, BALM and de novo pre-B ALL cells failed to stimulate T cells, but suppressed stimulated T cells. The DC-like cells displayed characteristic features of DCs: filiform cytoplasmic projections, and phenotypic expression of co-stimulatory molecules CD80/86, MHC Class I and II molecules, CD83 and CD1a. Genetic monoclonality study confirmed their leukemic origin. In a 5-day MLR culture, the DC-like cells potently activated allogeneic adult and cord CD4+ and CD8+ T cells. Furthermore, both CD4+ and CD8+ T cells were primed towards a Type I. No such effect was seen with unmanipulated de novo pre-B ALL cells. DISCUSSION DC-like cells can be generated from childhood pre-B ALL cells and are potent stimulators of adult and naïve cord CD8+ T cells via CD4+ cells. These cells may form part of an immunotherapy strategy to overcome tolerance to ALL cells.

Abstract
Adult patients with acute leukemia have, in general, a poor prognosis, with long-term, disease-free survival achieved in only approximately one-third of cases. One of the proposed mechanisms for this poor overall response is the inability of the immune system to detect and eliminate residual malignant leukemia cells, which subsequently serve as a source of leukemic relapse. This review discusses the rationale of immunotherapy for acute leukemia and presents in vitro and in vivo model systems that were devised for pre-B acute lymphocytic leukemia (ALL) and acute myeloid leukemia (AML). New advances in the ex vivo manipulation of acute leukemia cells are presented, which attempt to modify these cells into functional antigen-presenting cells. These cells can then be used as autologous vaccines at the time of minimal residual disease after standard chemotherapy, to stimulate host immune responses against their own leukemia cells. The various approaches toward this aim include incubation of leukemia cells with cytokines or growth factors and gene manipulation of these cells. In particular, ex vivo culture of ALL cells with CD40 ligand, incubation of AML cells with granulocyte-macrophage colony-stimulating factor and interleukin-4 (GM-CSF/IL-4) and lentiviral transduction of ALL and AML cells for expression of immunomodulators (CD80 and GM-CSF) are current approaches under investigation for the development of autologous acute leukemia cell vaccines.

Abstract
Acute myeloid leukemia (AML) patients treated with available therapies achieve remission in approximately 60% of cases, but the long-term event-free survival is less than 30%. Use of immunotherapy during remission is a potential approach to increase survival. We propose to develop cell vaccines by genetic modification of AML cells with CD80, an essential T cell costimulator that is lacking in the majority of AML cases, and GM-CSF, to induce proliferation and activation of professional antigen-presenting cells. Here, we evaluated third generation self inactivating (SIN) lentiviral vectors, which have the potential advantage of improved safety. CD80 and GM-CSF expression by these vectors was higher than that reported with second generation vectors (Stripecke et al, Blood 2000; 96: 1317-1326). In some cases, endogenous GM-CSF expression by transduced AML cells induced phenotypic changes consistent with the maturation of leukemia blasts into antigen-presenting cells. Further, in all cases studied, GM-CSF expression was associated with higher proliferation and cell viability. Allogeneic and autologous mixed lymphocyte reactions performed with transduced irradiated AML cells expressing CD80 and/or GM-CSF demonstrated that expression of either transgene enhanced T cell activation. These pre-clinical data demonstrate the potential feasibility of third generation SIN vectors for use in AML immunotherapy.

Abstract
PURPOSE A reason that the immune system may fail to reject tumors is that T cells encounter tumor antigen derived peptides on the surface of tumor cells in a tolerizing rather than activating context since tumor cells do not express T cell co-stimulatory molecules such as B7-1 (CD80). In preclinical models over expression of B7-1 on the surface of tumor cells has been shown to activate T cells which kill tumor cells. We conducted a phase I clinical trial testing this approach in patients with metastatic renal cell carcinoma. MATERIALS AND METHODS Resected tumors from 15 patients were disaggregated and adapted to tissue culture, transduced with the B7-1 gene and injected subcutaneously as a vaccine. The dose of the vaccine was escalated in 3 separate cohorts of patients, and systemic interleukin-2 (IL-2) was administered as an adjuvant designed to enhance the proliferation of the vaccine activated T cells. RESULTS Of the 15 patients 9 had measurable disease, 2 had a partial response and 2 had stable disease. Perivascular T cell infiltrates at autologous tumor delayed type hypersensitivity skin test sites developed in 3 of the 4 patients with stable disease or partial response. Although the patients experienced the usual and expected toxicity from the IL-2, there was no significant toxicity observed with the vaccine. CONCLUSIONS The B7-1 gene modified autologous tumor cell vaccine is safe and can be combined with systemic IL-2 with acceptable toxicity. Immunological and clinical responses were observed in some of the patients. A phase II trial is reasonable to determine the efficacy of this approach.

Abstract
Dendritic cells (DCs) are professional antigen presenting cells derived from myeloid or lymphoid precursors. Functional DCs have been generated from the malignant counterpart of these precursor cells. Herein, we describe the generation of DCs from different leukemias and determine the optimal culture conditions with minimal manipulation. Primary leukemic cells were cultured for 1, 3, and 5 days in 11 different cytokine combinations and analyzed for the expression of a mature DC phenotype. Optimal growth and DC characteristics were obtained with GM-CSF, FL, and SCF in 3-5 day cultures, suggesting a practical strategy for the immunotherapy of leukemia.

Abstract
OBJECTIVE To elucidate the mechanism of immunologic escape of leukemia cells and establish an effective anti-leukemia immunotherapy, we attempted to generate dendritic cells from leukemia cells in patients with acute myelogenous leukemia (AML). Using these leukemia-derived dendritic cells, we investigated leukemia cell-associated T-cell anergy. MATERIALS AND METHODS Leukemia cells of 30 patients with AML were cultured with granulocyte-macrophage colony-stimulating factor, interleukin-4, and tumor necrosis factor-alpha. Cultured leukemia cells were evaluated for antigen-presenting ability by mixed leukocyte culture (MLC). Normal lymphocytes, which were cocultured with leukemia blasts in the first MLC, were cultured with leukemia-derived dendritic cells in the second MLC. RESULTS In cultures of leukemia cells from 21 of 30 patients examined, cells with stellate morphology and cell fractions with CD1a(+) and/or CD83(+) were present. Autologous MLC using lymphocytes obtained in remission phase as responders as well as allogeneic MLC demonstrated antigen-presenting ability in leukemia-derived dendritic cells. Leukemia cells of FAB-M0, M1, M2, M3, or M6 morphology/phenotype gave rise to dendritic cells as well as leukemia cells of M5. The leukemic origin of dendritic cells was suggested by in situ hybridization. By coculture with CD80(-) leukemia blasts, the response of normal lymphocytes to leukemia-derived dendritic cells cultured from the same individual as that of leukemia blasts was markedly reduced, compared with the lymphocytes cultured with leukemia blasts from a different individual as leukemia blasts. CONCLUSIONS Escape of leukemia cells from anti-leukemia immunity may be associated with T-cell anergy caused by leukemia blasts. The results of the present study suggest that leukemia-derived dendritic cells can be applied efficiently in anti-leukemia immunotherapy.

Abstract
In the last decade our understanding of the processes that govern cell growth and differentiation, malignant transformation, and metastasis has become quite sophisticated. These new insights have revolutionized our ability to diagnose and to formulate prognoses for patients with cancer, and have inspired the design and development of novel therapeutic strategies that are based on modern gene-transfer technologies and act at the gene level. Gene therapy, broadly defined as the introduction of genetic material (transgenes) into a patient's cells with an intent to confer a therapeutic benefit, represents the most direct application of recombinant DNA technology in the clinical setting. The challenging concept of modifying the genetic properties of human cells captivated very quickly the interest of clinical and molecular oncologists, and currently, numerous gene therapy clinical trials in cancer patients are under investigation worldwide. Most of these studies involve manipulating the patient's immune response to tumors. The identification of tumor-specific antigens stimulating humoral and cellular responses in cancer patients, together with a better understanding of the molecular mechanisms controlling T cell activation have dramatically accelerated the search for potent cancer vaccines. In this review, we highlight important principles of cancer immunity and cancer vaccines, we discuss critical features of genetic manipulation of tumor cells, and particularly focus on preclinical studies on gene therapy vaccines in acute myeloid leukemia (AML).

Abstract
We have selected a well-characterized human renal cell carcinoma (RCC) line as the basis for development of a genetically engineered tumor cell vaccine to be applied in an allogeneic setting. This cell line was genetically modified by retroviral transduction to express B7.1 costimulatory molecules. The unmodified tumor cells and B7.1-expressing tumor cells were compared for their ability to induce tumor-associated responses in allogeneic peripheral blood mononuclear cells (PBMC) of two normal control donors having single MHC class I allele matches with the tumor cells. PBMC primed using B7.1-modified tumor cells showed a preponderance of CD3+CD8+ cytotoxic T lymphocytes (CTL) that proliferated over extended periods of time in mixed lymphocyte tumor cell (MLTC) cultures. Strong cytolytic activity developed in the primed populations and included allospecific CTL with specificity for mismatched HLA-A, -B and -C molecules. Nevertheless, it was possible to isolate CTL clones that were able to lyse tumor cells but not lymphoblastoid cells that expressed all the corresponding allospecificities. Thus, induction of complex allospecific responses did not hinder the development of tumor-associated CTL in vitro. These results support the use of this genetically modified allogeneic tumor cell line for vaccination of partial-MHC matched RCC patients.

Abstract
Expression of B7 molecules provides co-stimulatory signals to T lymphocytes, which prevent the induction of anergy. It has been previously reported that B7.1 gene transfer in a murine leukaemia model induced a potent antileukaemic immunity and that relative expression of B7.1 and B7.2 in human acute myeloid leukaemia (AML) had prognostic significance. As ex vivo engineering of leukaemic cells for immunotherapy protocols would require prior irradiation of these cells before reinjection to the patient, we investigated in murine and leukaemic cell lines and in 20 ex vivo primary cultured acute myeloid leukaemic cells the effect of gamma-irradiation on the expression of B7 molecules. We observed that gamma-irradiation enhanced B7.1 molecule expression in murine leukaemic cell lines and in B7.2 molecules in human HL60 and K562 cell lines. gamma-Irradiation induced B7.1 molecule expression in 90% AML samples but only 21% showed B7.2 molecule expression enhancement. B7.1 expression was increased both at the protein and RNA level in human AML cells but only at the protein level in the DA1-3b murine cell line. Oxidative stress increased B7.1 expression in the murine DA1-3b cell line but human cell lines and AML samples remained unaffected both by heat shock and oxidative stress, suggesting different pathways of B7.1 induction between mouse and human cells. Our data show that B7.1 expression can be induced by ex vivo irradiation of AML cells, indicating that these cells can express co-stimulatory molecules without gene transfer.

Abstract
We previously reported that treatment of human peripheral blood monocytes or dendritic cells (DC) with calcium ionophore (CI) led to the rapid (18 hour) acquisition of many characteristics of mature DC, including CD83 expression. We therefore investigated whether less-mature myeloid cells were similarly susceptible to rapid CI activation. Although the promyelocytic leukemia line HL-60 was refractory to cytokine differentiation, CI treatment induced near-uniform overnight expression of CD83, CD80 (B7.1), and CD86 (B7.2), as well as additional characteristics of mature DC. Several cytokines that alone had restricted impact on HL-60 could enhance CI-induced differentiation and resultant T-cell sensitizing capacity. In parallel studies, CD34pos cells cultured from normal donor bone marrow developed marked DC-like morphology after overnight treatment with either rhCD40L or CI, but only CI simultaneously induced upregulation of CD83, CD80, and CD86. This contrasted to peripheral blood monocytes, in which such upregulation could be induced with either CI or rhCD40L treatment. We conclude that normal and transformed myeloid cells at many stages of ontogeny possess the capacity to rapidly acquire many properties of mature DC in response to CI treatment. This apparent ability to respond to calcium mobilization, even when putative signal-transducing agents are inoperative, suggests strategies for implementing host antileukemic immune responses.

Abstract
Human hepatocellular carcinoma (HCC) frequently recurs after primary therapy, resulting in poor prognosis. To try to find a way to prevent this, we examined the combined effectiveness of B7-1 (CD80)-gene transfer and interleukin-12 (IL-12) on the induction of protective antitumor immunity against poorly immunogenic BNL1ME A.7R. 1 (BNL) mouse HCC cells. We introduced mouse B7-1 gene into BNL1ME A. 7R.1 cells. Overexpression of B7-1 on BNL1ME A.7R.1 cells resulted in significant inhibititon of subcutaneous tumor development in syngeneic BALB/c mice, but not in complete rejection, suggesting that strong expression of B7-1 molecules may enhance the immunogenicity of BNL1ME A.7R.1 cells in immunocompetent mice. Lymphocyte study revealed that the cytolytic activity generated by immunization with B7-1 transfectants against BNL1ME A.7R.1 cells was mediated mainly by CD8(+) cytotoxic T lymphocytes (CTL). We examined the synergistic effect of IL-12 and immunization with B7-1 transfectants. The combination led to rejection of BNL1ME A.7R.1 cells in 6 of 10 tested mice and delayed tumor development in the remaining mice. Furthermore, the combined treatment against pre-established BNL1ME A.7R.1 tumors resulted in rejection in 3 of 8 tested mice or in significant inhibition of tumor growth in the remaining mice. In vivo lymphocyte subset depletion study indicated that the combined antitumor effect was dependent on the presence of both CD8(+) and CD4(+) T cells. In conclusion, the combination of immunization of B7-1-transfected HCC cells and IL-12 could induce protective and therapeutic immunity against parental HCC cells, and this combination may be therapeutically useful for suppressing recurrence of HCC.
