Abstract
Adoptive transfer of tumor-infiltrating lymphocytes (TIL) elicits the regression of metastatic malignancies, yet a low proportion of patients achieve complete durable responses. The high incidence of relapse in these patients highlights the need to better understand mechanisms of tumor escape from T cell control. While melanoma has provided the foundation for developing TIL therapy, much less is known about TIL efficacy and relapse in other malignancies. We sought to investigate TIL characteristics in mouse tumors which have not been studied in this setting. Here, we expanded murine TIL ex vivo in IL-2 from fragments of multiple tumor models, including oral cavity cancer models of varying immunogenicity. Additionally, TIL was expanded from pmel-1 mice bearing B16F10 melanoma, yielding an enriched population of tumor-infiltrating TCR transgenic T cells. Murine TIL are similar to human TIL in that they express high levels of inhibitory receptors (PD-1, Tim-3, etc.) and can be expanded ex vivo in IL-2 extensively. Of clinical relevance, we draw parallels between murine and human oral cavity cancer TIL, evaluating relationships between inhibitory receptor expression and function. This platform can be used by labs even in the absence of clinical specimens or clean cell facilities and will be important to more broadly understand TIL phenotypes across many different malignancies.

Abstract
Reactivation of latent cytomegalovirus (CMV) endangers the therapeutic success of hematopoietic cell transplantation (HCT) in tumor patients due to cytopathogenic virus spread that leads to organ manifestations of CMV disease, to interstitial pneumonia in particular. In cases of virus variants that are refractory to standard antiviral pharmacotherapy, immunotherapy by adoptive cell transfer (ACT) of virus-specific CD8+ T cells is the last resort to bridge the "protection gap" between hematoablative conditioning for HCT and endogenous reconstitution of antiviral immunity. We have used the well-established mouse model of CD8+ T-cell immunotherapy by ACT in a setting of experimental HCT and murine CMV (mCMV) infection to pursue the concept of improving the efficacy of ACT by therapeutic vaccination (TherVac) post-HCT. TherVac aims at restimulation and expansion of limited numbers of transferred antiviral CD8+ T cells within the recipient. Syngeneic HCT was performed with C57BL/6 mice as donors and recipients. Recipients were infected with recombinant mCMV (mCMV-SIINFEKL) that expresses antigenic peptide SIINFEKL presented to CD8+ T cells by the MHC class-I molecule Kb. ACT was performed with transgenic OT-I CD8+ T cells expressing a T-cell receptor specific for SIINFEKL-Kb. Recombinant human CMV dense bodies (DB-SIINFEKL), engineered to contain SIINFEKL within tegument protein pUL83/pp65, served for vaccination. DBs were chosen as they represent non-infectious, enveloped, and thus fusion-competent subviral particles capable of activating dendritic cells and delivering antigens directly into the cytosol for processing and presentation in the MHC class-I pathway. One set of our experiments documents the power of vaccination with DBs in protecting the immunocompetent host against a challenge infection. A further set of experiments revealed a significant improvement of antiviral control in HCT recipients by combining ACT with TherVac. In both settings, the benefit from vaccination with DBs proved to be strictly epitope-specific. The capacity to protect was lost when DBs included the peptide sequence SIINFEKA lacking immunogenicity and antigenicity due to C-terminal residue point mutation L8A, which prevents efficient proteasomal peptide processing and binding to Kb. Our preclinical research data thus provide an argument for using pre-emptive TherVac to enhance antiviral protection by ACT in HCT recipients with diagnosed CMV reactivation.

Abstract
Application of cancer vaccines is limited due to their systemic immunotoxicity and inability to satisfy all the steps, including loading of tumor antigens, draining of antigens to lymph nodes (LNs), internalization of antigens by dendritic cells (DCs), DC maturation, and cross-presentation of antigens for T cell activation. Here, we present a combinatorial therapy, based on a α-cyclodextrin (CD)-based gel system, DOX/ICG/CpG-P-ss-M/CD, fabricated by encapsulating doxorubicin (DOX) and the photothermal agent indocyanine green (ICG). Upon irradiation, the gel system exhibited heat-responsive release of DOX and vaccine-like nanoparticles, CpG-P-ss-M, along with chemotherapy- and phototherapy-generated abundant tumor-specific antigen storage in situ. The released CpG-P-ss-M acted as a carrier adsorbed and delivered antigens to LNs, promoting the uptake of antigens by DCs and DC maturation. Notably, combined with PD-L1 blocking, the therapy effectively inhibited primary tumor growth and induced tumor-specific immune response against tumor recurrence and metastasis.

Abstract
T cell expression of inhibitory proteins can be a critical component for the regulation of immunopathology owing to self-reactivity or potentially exuberant responses to pathogens, but it may also limit T cell responses to some malignancies, particularly if the tumor Ag being targeted is a self-protein. We found that the abrogation of Src homology region 2 domain-containing phosphatase-1 (SHP-1) in tumor-reactive CD8(+) T cells improves the therapeutic outcome of adoptive immunotherapy in a mouse model of disseminated leukemia, with benefit observed in therapy employing transfer of CD8(+) T cells alone or in the context of also providing supplemental IL-2. SHP-1(-/-) and SHP-1(+/+) effector T cells were expanded in vitro for immunotherapy. Following transfer in vivo, the SHP-1(-/-) effector T cells exhibited enhanced short-term accumulation, followed by greater contraction, and they ultimately formed similar numbers of long-lived, functional memory cells. The increased therapeutic effectiveness of SHP-1(-/-) effector cells was also observed in recipients that expressed the tumor Ag as a self-antigen in the liver, without evidence of inducing autoimmune toxicity. SHP-1(-/-) effector CD8(+) T cells expressed higher levels of eomesodermin, which correlated with enhanced lysis of tumor cells. Furthermore, reduction of SHP-1 expression in tumor-reactive effector T cells by retroviral transduction with vectors that express SHP-1-specific small interfering RNA, a translatable strategy, also exhibited enhanced antitumor activity in vivo. These studies suggest that abrogating SHP-1 in effector T cells may improve the efficacy of tumor elimination by T cell therapy without affecting the ability of the effector cells to persist and provide a long-term response.

Abstract
The clinical use of adoptive immunotherapy with tumor-reactive T cells to treat established cancers is limited in part by the poor in vivo survival and function of the transferred T cells. Although administration of exogenous cytokines such as IL-2 can promote T cell survival, such strategies have many nonspecific activities and are often associated with toxicity. We show here that abrogating expression of Casitas B-lineage lymphoma b (Cbl-b), a negative regulator of lymphocyte activation, in tumor-reactive CD8(+) T cells expanded ex vivo increased the efficacy of adoptive immunotherapy of disseminated leukemia in mice. Mechanistically, Cbl-b abrogation bypassed the requirement for exogenous IL-2 administration for tumor eradication in vivo. In addition, CD8(+) T cells lacking Cbl-b demonstrated a lower threshold for activation, better survival following target recognition and stimulation, and enhanced proliferative responses as a result of both IL-2-dependent and -independent pathways. Importantly, siRNA knockdown of Cbl-b in human CD8(+)CD28- effector T cell clones similarly restored IL-2 production and proliferation following target recognition independent of exogenous IL-2, enhanced IFN-γ production, and increased target avidity. Thus, abrogating Cbl-b expression in effector T cells may improve the efficacy of adoptive therapy of some human malignancies.

Abstract
The cooperative role of CD4+ helper T (Th) cells has been reported for CD8+ cytotoxic T (Tc) cells in tumor eradication. However, its molecular mechanisms have not been well elucidated. We have recently demonstrated that CD4+ Th cells can acquire major histocompatibility complex/peptide I (pMHC I) complexes and costimulatory molecules by dendritic cell (DC) activation, and further stimulate naïve CD8+ T cell proliferation and activation. In this study, we used CD4+ Th1 and CD8+ Tc1 cells derived from ovalbumin (OVA)-specific T cell receptor (TCR) transgenic OT II and OT I mice to study CD4+ Th1 cell's help effects on active CD8+ Tc1 cells and the molecular mechanisms involved in CD8+ Tc1-cell immunotherapy of OVA-expressing EG7 tumors. Our data showed that CD4+ Th1 cells with acquired pMHC I by OVA-pulsed DC (DCOVA) stimulation are capable of prolonging survival and reducing apoptosis formation of active CD8+ Tc1 cells in vitro, and promoting CD8+ Tc1 cell tumor localization and memory responses in vivo by 3-folds. A combined adoptive T-cell therapy of CD8+ Tc1 with CD4+ Th1 cells resulted in regression of well-established EG7 tumors (5 mm in diameter) in all 10/10 mice. The CD4+ Th1's help effect is mediated via the helper cytokine IL-2 specifically targeted to CD8+ Tc1 cells in vivo by acquired pMHC I complexes. Taken together, these results will have important implications for designing adoptive T-cell immunotherapy protocols in treatment of solid tumors.

Abstract
The prognostic significance of tumor-infiltrating lymphocytes (TILs) has been a longstanding topic of debate. In cases where TILs have improved patient outcome, T lymphocytes are recognized as the main effectors of antitumor immune responses. However, recent studies have revealed that a subset of CD4(+) T cells, referred to as CD4(+)CD25(+) regulatory T cells (Treg), may accumulate in the tumor environment and suppress tumor-specific T-cell responses, thereby hindering tumor rejection. Hence, predicting tumor behavior on the basis of an indiscriminate evaluation of tumor-infiltrating T cells may result in inconsistent prognostic accuracy. The presence of infiltrating CD4(+)CD25(+) Treg may be detrimental to the host defense against the tumor, while the presence of effector T lymphocytes, including CD8(+) T cells and non-regulatory CD4(+) helper T cells may be beneficial. Enhanced recruitment of antitumor effector T lymphocytes to tumor tissue in addition to inhibition of local Treg, may therefore be an ideal target for improving cancer immunotherapy. This article reviews the antitumor functions of T-lymphocytes, with special attention given to CD4(+) regulatory T-cells within the tumor environment.

Abstract
Despite remarkable advancements in imaging modalities and treatment options available to patients diagnosed with malignant brain tumors, the prognosis for those with high-grade lesions remains poor. The imprecise mechanisms of currently available treatments to manage these tumors do not spare damage to the normal surrounding brain and often result in major cognitive and motor deficits. Immunotherapy holds the promise of offering a potent, yet targeted, treatment to patients with brain tumors, with the potential to eradicate the malignant tumor cells without damaging normal tissues. The T cells of the immune system are uniquely capable of recognizing the altered protein expression patterns within tumor cells and mediating their destruction through a variety of effector mechanisms. Adoptive T-cell therapy is an attempt to harness and amplify the tumor-eradicating capacity of a patients' own T cells and then return these effectors to the patient in such a state that they effectively eliminate residual tumor. Although this approach is not new to the field of tumor immunology, new advancements in our understanding of T-cell activation and function and breakthroughs in tumor antigen discovery hold great promise for the translation of this modality into a clinical success.

Abstract
With FDA approval of monoclonal antibodies (mAb) against the B-cell-specific cell surface molecule CD20, immunotherapy in B-cell non-Hodgkin's-lymphomas (NHL) has gained momentum. Since the first description of the CD20 mAb and its use in a single patient, it has taken more than 20 years to implement this in current treatment options. NHLs are of particularly interest to the research community, since a whole array of novel immunotherapeutic strategies are currently in development. Unconjugated and radioconjugated mAbs are either approved, or in Phase III trials with very promising results. Adoptive transfer of polyclonally activated, tumour-specific or antigen-specific T-cells are in Phase I and II trials. Even antisense approaches have reappeared in the treatment of NHL. However, it is not only passive immunotherapy that has evolved. There are several new strategies for vaccination in NHL, whilst older approaches are under revision. Vaccine strategies targeting the tumour cell specific clonal idiotype (Id) have been refined and, with the identification of T-cell responses against shared epitopes, vaccination against the clonal Id might finally become clinically applicable. Significant progress has also been made in the development of cellular vaccines. Malignant B-cells are turned into 'tumour-APC' and are used to stimulate T-cell responses in Phase I trials. Moreover, with the identification of universal tumour antigens, another antigen-specific vaccine for NHL can be envisioned. By combining this array of very promising tools, immunotherapy might finally become a standard modality for the treatment of B-cell malignancies.

Abstract
In order to maintain in vivo anti-tumor efficacy of antigen (Ag)-specific T cells in adoptive immunotherapy for a prolonged period, we constructed a fusion protein (OVA/IL-2) containing ovalbumin (OVA) as a model tumor Ag, co-valently linked to murine interleukin-2 (IL-2). The OVA/IL-2 protein produced in a baculovirus expression system displayed potent IL-2 bio-activity. Immunization with the OVA/IL-2 protein after adoptive transfer of OVA-specific T cells maintained the OVA-specific cytotoxicity and cell number of adoptively transferred T cells long term in vivo, while a simple mixture of recombinant OVA (rOVA) and rIL-2 did not. The response was dependent on the injection doses and times of the OVA/IL-2 protein. Furthermore, weekly re-stimulation of adoptively transferred OVA-specific T cells with the OVA/IL-2 protein cured 70% of tumor-bearing mice. In contrast, re-stimulation with a mixture of rOVA and rIL-2 could not significantly prolong the survival period of tumor-bearing mice. These studies suggest that the co-valent linkage between IL-2 and antigen confines the effect of IL-2 to antigen-specific T cells, leading to efficient maintenance of the anti-tumor activity of adoptively transferred T cells.

Abstract
Dendritic cells (DC) are professional antigen-presenting cells (APC) within the immune system and antigen-pulsed DC can be used as an effective vaccine for active immunotherapy of cancer. Granulocyte-macrophage colony-stimulating factor (GM-CSF) plays an important role in the generation of DC. We previously showed that GM-CSF can induce murine erythroleukaemia cells (FBL-3) to differentiate into monocyte-like cells. To develop a new vaccinating method to stimulate the host immune response to leukaemia, we further investigate whether FBL-3 cells induced by GM-CSF can differentiate into DC in the present study. After being treated with GM-CSF, FBL-3 cells expressed high levels of 33D1 and NLDC-145, which are the specific markers of DC. The expression of MHC-II, B7-1, B7-2 and vascular cell adhesion molecule-1 (VCAM-1) was up-regulated markedly; the typical morphology of DC were also observed by electron microscopy. Functionally, the GM-CSF-induced FBL-3 cells could apparently stimulate the proliferation of naive allogeneic and autologous T lymphocytes and induce the generation of specific CTL more efficiently than the wild-type FBL-3 cells. Mice immunized with GM-CSF-induced FBL-3 cells could resist the subsequent challenge with the wild-type FBL-3 cells. Collectively, these data indicate that GM-CSF differentiates murine erythroleukaemia cells into DC phenotypically, morphologically and functionally.

Abstract
Human chronic myelogenous leukemia (CML) is characterized by a translocation between chromosomes 9 and 22 that results in a BCR-ABL fusion gene coding for chimeric proteins. The junctional region of the BCR-ABLb3a2 molecule represents a potential leukemia-specific antigen which could be recognized by cytotoxic T lymphocytes (CTL). In fact, we identified a junctional nonapeptide (SSKALQRPV) which binds to HLA-A2.1 molecules. This peptide, as well as those binding to HLA-A3, -A11, and -B8 molecules (previously identified by others), elicits primary CTL responses in vitro from PBLs of both healthy donors and CML patients. Such CTL recognize HLA-matched, BCR-ABL-positive leukemic cells, implying efficient natural processing and presentation of these junctional peptides. Specific CTL were found at high frequency in 5 of 21 CML patients, suggesting that these epitopes are, to some extent, immunogenic in vivo during the course of the disease. These peptides could be useful for the development of specific immunotherapy in CML patients.

Abstract
The mechanisms that maintain memory in T cells are not completely understood. We have investigated the role of antigen and interleukin (IL)-2 in the growth and maintenance of CD8+ T cells using a cytolytic T cell line specific for ovalbumin (OVA)257-264 presented by H-2Kb. This line does not secrete IL-4 or IL-2; hence, stimulation with the OVA-transfected EL4 line (E.G7-OVA) does not induce proliferation without addition of exogenous growth factors. Furthermore, this line can be maintained continuously by weekly addition of irradiated, splenic filler cells and IL-2, with or without E.G7-OVA. Although IL-2 induced proliferation of these cytotoxic T lymphocytes (CTLs), production of interferon gamma and tumor necrosis factor alpha required stimulation of the CTL with E. G7-OVA. The kinetics of lymphokine secretion after stimulation by E. G7-OVA were the same whether the CTL had been maintained with or without antigen (Ag). In addition, both CTL lines killed E.G7-OVA target cells within 4 h. Thus, the effector functions of these CTLs were rapidly induced by T cell receptor (TCR) occupancy. CTLs cultured with or without Ag also served as memory T cells when parked for 100 d in unirradiated, syngeneic recipients without OVA. In the absence of OVA, the precursor frequency was identical in spleens of normal and beta2-microglobulin knockout recipients, but significantly less in IL-2 knockout mice. The decline of memory in the absence of IL-2 supports data from other investigators, suggesting that cell cycling is important to the maintenance of CD8+ T cell memory. These data also suggest that stimulation of OVA-specific CTLs by lymphokines seems to be more important to maintaining memory than stimulation of TCRs by cross-reactive peptides complexed to class I molecules.

Abstract
In animals and in humans, T-cell therapy can cure advanced disseminated leukemia that would otherwise be fatal. The therapeutic effect of immune T cells is quantitative. As the dose of effector T cells is increased, survival is proportionately increased. Therefore, effective T-cell therapy is predicated on the ability to procure large numbers of immune effector T cells. By using cultured T cells, the number of immune T cells can be increased in vivo substantially above the level achievable by vaccination. The survival of cultured T cells in vivo is dependent upon both the culture conditions used and the therapeutic regimens employed. Under appropriate conditions, cultured T cells can proliferate in vivo in response to stimulation by antigen, distribute widely and survive long term to provide effector function and immunologic memory. Given that T cells recognize peptides, the need for immunization with tumor can be circumvented by immunization with peptide. Peptide-specific T cells and the progeny of single T-cell clones can provide the necessary cellular functions to eradicate disseminated murine leukemia. The ability of cloned T cells to similarly provide substantial measurable immunity in humans has been validated in clinical trials. By priming with peptides and by using established culture conditions, T-cell therapy can now be directed against virtually any antigen within the host T-cell repertoire. The major remaining question to be answered is which proteins and which peptides are the most suitable targets for T-cell therapy trials.

Abstract
Abstract
Relapse is more frequent after autologous than allogeneic bone marrow transplantation (BMT), due in part to lack of T-lymphocyte mediated allogeneic graft-versus-leukemia (GVL) effects. Infusions of leukemia-reactive T cells to patients after autologous BMT may be a means for providing a GVL effect. Costimulation of T cells by binding of the CD28 receptor on T cells with B7-counter receptors on antigen presenting cells amplifies antigen-specific T-cell responses. To enhance generation of leukemia reactive cytotoxic T lymphocytes (CTL), the murine B7-1– and B7-2–costimulatory molecule cDNAs were introduced into the MHC class I+, class II−, murine meyloid leukemia cell line C1498. B7-1 expression greatly enhanced the ability of the leukemia cells to generate and expand leukemia reactive CTL in vitro. A highly cytolytic and C1498 specific CD8+ CTL line was generated by B7-1 costimulation. This CTL line proliferated autonomously and produced interleukin-2 when provided B7-1 or B7-2 costimulation by C1498 leukemia cells. To test the in vivo antileukemia properties of this CTL line, irradiated syngeneic BMT recipients were given graded doses of leukemia cells on day 0, followed by CTL infusions beginning on day 1 post-BMT. Recipients of 107 CTL had a 3 log reduction in leukemia burden such that 100% of mice were protected from a supralethal leukemic cell dose. Sustained immune responses were detectable up to 3 months postinfusion of the CTL line. B7-1 or B7-2 costimulation in vivo did not augment antileukemia effects of infused CTL post BMT. These results suggest that B7 costimulation of leukemia reactive CTL may be important for their ex vivo generation and expansion for use in human adoptive immunotherapy of leukemia.

Abstract
The HER-2/neu oncogenic protein is a tumor antigen. Some patients with cancer have a preexistent immune response directed against the HER-2/neu protein. Effective cancer vaccines targeting HER-2/neu will be able to boost this immunity to potentially therapeutic levels. In addition, HER-2/neu-directed monoclonal antibody therapy has been effective in eradicating malignancy in animal models and has shown benefit in the treatment of human HER-2/neu-overexpressing cancers. This review outlines studies that define HER-2/neu-specific immunity in patients with cancer and overviews the current vaccine strategies for generating or augmenting neu-specific immunity. The potential problems associated with eliciting HER-2/neu-specific immunity are addressed, including the question of precipitating autoimmune toxicity against this "self" -protein and the mechanisms of immunological escape that may play a role in preventing effective function of the HER-2/neu-specific immune response. Finally, antibody-based HER-2/neu-directed therapies are overviewed. HER-2/neu is a prototype antigen for groups investigating innovative modifications of monoclonal antibody technology, and cutting edge therapies targeting this antigen are being contemplated for clinical use in the treatment of human malignancy. Immune-based treatments designed to target the HER-2/neu oncogenic protein will soon give the clinical oncologist new therapeutic weapons, directed against a biologically relevant tumor-related protein, with which to fight cancer.

Abstract
Adoptive transfer of splenic T lymphocytes from DBA/2 mice immunized against Friend erythroleukemia cells (FLC) inhibited the development of visceral metastases and increased the survival time of DBA/2 mice challenged i.v. with parental FLC 24 hr to 2 months later. Immune spleen cells were ineffective in mice pre-treated with potent neutralizing antibody to mouse IFN alpha/beta (but not to IFN gamma), demonstrating the essential participation of endogenous IFN alpha/beta in the inhibitory action of immune T lymphocytes against FLC metastases. These findings suggest that the reported inability of immune T lymphocytes to exert an anti-FLC effect in immunodeficient DBA/2 mutant beige (bg/bg) mice (unless these mice had also been treated with IFN alpha/beta), may have been due to lower levels of endogenous IFN alpha/beta in DBA/2 bg/bg mice than in normal DBA/2+/bg mice. Experimental results in support of this hypothesis are presented.

Abstract
Leishmania major promastigote surface antigen-2 complex (PSA-2) comprises a family of three similar but distinct polypeptides. The three PSA-2 polypeptides were purified from cultured promastigotes by a combination of detergent phase separation and monoclonal antibody affinity chromatography. Intraperitoneal vaccination of C3H/He mice with PSA-2 with Corynebacterium parvum as an adjuvant resulted in complete protection from lesion development after challenge infection with virulent L. major. Significant protection was also obtained in the genetically susceptible BALB/cH-2k and BALB/c mice. One of the PSA-2 genes was cloned and expressed in both Escherichia coli and Leishmania mexicana promastigotes. Vaccination with the recombinant PSA-2 purified from E. coli did not confer protection, in contrast to the L. mexicana-derived recombinant PSA-2, which provided excellent protection. CD4+ T cells isolated from the spleens of vaccinated mice produced large amounts of gamma interferon but no detectable interleukin 4 upon stimulation with PSA-2 in vitro. Limiting dilution analysis showed a marked increase in the precursor frequency of PSA-2-specific gamma interferon-secreting CD4+ T cells. No substantial change in precursor frequency was observed for interleukin 4-secreting T cells in the vaccinated mice. A CD4+ PSA-2 specific T-cell line generated from splenocytes of a vaccinated mouse produces a cytokine pattern consistent with a TH1 phenotype. Intravenous injection of this line into naive mice reduced significantly the parasite burden upon challenge infection. Taken together, the data suggest that vaccination with PSA-2 induces a TH1 type of immune response which protects mice from L. major infection. Moreover, a single recombinant PSA-2 polypeptide derived from a genomic clone can also vaccinate, provided that the structural form of the antigen is near native.

Abstract
The MAGE-1 gene encodes a tumor-specific antigen, MZ2-E, which is recognized by cloned, specific cytolytic T cells (CTL) derived from the peripheral blood of a patient with melanoma. We have produced a MAGE-1-specific CTL line derived from the tumor-infiltrating lymphocytes (TIL) of a melanoma patient by weekly restimulation with autologous EBV-B cells pulsed with the synthetic HLA-A1-restricted MAGE-1 epitope nonapeptide EADPTGHSY. The 1277.A TIL line grew in long-term culture in low-dose interleukin-2 (IL-2) and IL-4, and exhibited antigen-specific, MHC-class-I-restricted lysis of HLA-A1-bearing MAGE-1+ cell lines. Cytolysis of target cells pulsed with the synthetic MAGE-1 decapeptide KEADPTGHSY was superior to that of cells pulsed with the immunodominant nonapeptide. Single amino-acid or even side-chain substitutions in the immunodominant nonamer abrogated cytolysis. 1277.A TIL specifically secreted tumor necrosis factor alpha after co-incubation with HLA-A1-expressing MAGE-1+ cell lines or fresh tumor. These data suggest that tumor-antigen-specific, MHC-restricted CTL may be grown from TIL in the presence of synthetic epitope peptides and expanded for adoptive immunotherapy in melanoma patients.

Abstract
Bone marrow transplantation (BMT) recipients are immunosuppressed and are at risk for contracting severe infections. Recently, adoptive transfer of immunity against hepatitis B virus (HBV) was documented in BMT recipients receiving bone marrow from 'naturally' HBV-infected individuals who recovered spontaneously, or those transplanted with bone marrow cells obtained from actively immunized donors. Furthermore, reconstitution of the immune system in a BMT recipient who was a hepatitis surface antigen (HBsAg)+/HBV DNA+ carrier with HBV immune bone marrow cells led to clearance of the replicating virus, presumably through adoptive cell-mediated immunotherapy. We report three cases of induction of immunity to HBV by selective adoptive transfer by i.v. injection of peripheral blood lymphocytes (PBL) obtained from BMT donors who were actively immunized against HBV after harvesting of bone marrow. All three BMT recipients developed anti-HBs antibodies. In one BMT case in whom antibodies to HBsAg developed following adoptive transfer of immune PBL, a mild booster effect was documented in the BMT recipient upon immunization with a recombinant hepatitis B vaccine. The two remaining patients lost their antibodies to HBsAg in association with relapse of leukaemia. This immune manipulation may open the door to evaluation of adoptive transfer of immunity to HBV through selective transplantation of HBV immune lymphocytes in selected patients such as those with persistent HBV infection, as well as liver transplant recipients who require protection of the graft against HBV re-infection.

Abstract
A major obstacle to the effective use of adoptive immunotherapeutic treatment of cancer is the difficulty of obtaining tumor-reactive lymphocytes in either sufficient numbers or with appropriate in vivo function to make such an approach feasible. Previous studies have shown that antitumor cytotoxic T lymphocytes (CTL) with in vivo efficacy can be generated in vitro from lymphoid cells obtained from lymph nodes that drain the anatomical site of a tumor. Results presented here demonstrate that inclusion of interleukin 7 (IL-7) into the medium in which such CTL are cultured can support their growth in vitro for prolonged periods of time in the absence of repeated stimulation with either tumor stimulator cells or tumor antigen. More importantly, antitumor CTL propagated in medium containing IL-7 have retained both their antigenic specificity and their ability to reject tumors in vivo subsequent to intravenous injection. Parallel cultures of antitumor CTL similarly cultured in medium containing only IL-2 could only be maintained for 5-6 wk, after which the number and proportion of viable cells that were recoverable from such cultures progressively decreased. Phenotypic analysis of CTL maintained after extended culture (i.e., 22 mo) in medium containing IL-7 demonstrated them to be CD3+4-8+ T cells. These cells were also found to express lymphocyte function associated 1, intercellular adhesion molecule 1, and Mel-14 cell interaction molecules. The data also demonstrate that these CTL do not require the presence of antigen-presenting cell populations to mount a proliferative response to tumor stimulator cells. Cells in these cultures were also demonstrated to produce IL-2 after stimulation with irradiated tumor cells, thereby indicating that these CTL have become independent of the requirement for CD4+ helper cells to survive and function either in vitro or in vivo. Collectively, the findings that IL-7 can beneficially augment the generation, and propagate the long-term growth, of antitumor CTL from lymph nodes draining a tumor site may have profound implications for promoting the immunotherapeutic treatment of cancer in humans.

Abstract
Antiviral cytotoxic memory CD8+ T cells adoptively transferred to mice which are persistently infected with lymphocytic choriomeningitis virus WE or DOCILE initially proliferated extensively; they either caused the death of the recipient or, alternatively, disappeared within a few days. Apparently, the complete and coordinated induction and stimulation by widely distributed viral antigen caused these memory T cells to die before virus had been eliminated from the host. Thus memory T cells are as susceptible to peripheral exhaustion/deletion as unprimed T cells. These results indicate possible limitations of exclusively CD8+ T cell-mediated adoptive immunotherapy against viral infections or tumors.

Abstract
The process of malignant transformation can be ascribed to a series of characteristics and definable mutations of genes which encode proteins that control cell growth and differentiation. During the course of malignant transformation the cancer-related genes are altered by a variety of mechanisms including translocations, deletions, and point mutations which commonly result in the expression of aberrant proteins. Our laboratory has focused on determining the extent to which cancer-specific proteins expressed by aberrant cancer-related genes can function as tumor-specific antigens. The current paper reviews our studies with two prototype cancer-specific proteins, mutated p21ras protein and chimeric p210bcr-abl protein. Ras protooncogenes are activated by point mutation in approximately 20% of human malignancies. The mutations occur primarily at codons 12 or 61 and result in the expression of p21ras proteins with single substituted amino acids. Only a limited number of amino acid substitutions occur. Murine studies demonstrate that immunization with synthetic peptides corresponding to the mutated segment can elicit both class II restricted CD4+ helper/inducer T-cell responses and class I restricted CD8+ cytotoxic T-cell responses specific for mutated p21ras protein. In addition, the existence in vivo of tumors expressing mutated ras proteins can be detected by assaying for T-cell immunity to the mutated segment of ras protein. Preliminary human studies show that some patients with colon cancer have existent antibody responses to p21ras protein, implying the possible existence of autochthonous T-cell immunity to mutated ras proteins in those patients. In chronic myelogenous leukemia the human c-abl protooncogene from chromosome 9 is translocated to the specific breakpoint cluster (bcr) region on chromosome 22. The translocation results in the formation of a bcr-abl fusion gene that encodes at 210-kD chimeric protein. The joining region segment of chimeric bcr-abl protein is composed of a unique combination of c-abl and bcr amino acids and is expressed only by malignant cells. Studies demonstrate that immunization of mice with synthetic peptides corresponding to the joining region segment can elicit class II restricted CD4+ T-cell responses to p210bcr-abl proteins. Preliminary studies show that bcr-abl peptides can bind in the groove of both murine and human class I MHC molecules and can elicit bcr-abl peptide-specific cytotoxic T lymphocytes (CTL). Whether bcr-abl peptide-specific CTL can lyse cells expressing bcr-abl protein is a yet unknown. In summary, the results of the studies reviewed confirm that cancer-specific oncogenic proteins can serve as tumor-specific antigens.

Abstract
Late tumor bearers (LTB), that is, mice that had tumors 3 weeks or longer, can have a selective immune dysfunction and fail to respond to target antigens expressed by the cancer cells. Such mice, however, do respond to nonmalignant cells engineered to express the rejection antigen, and they can be vaccinated with such cells to reject growing tumors. In this study, we compared the efficacy of passive immunization with that of active immunization using the engineered vaccine. An allogeneic MHC class I molecule was used as model tumor antigen. We found that active immunotherapy was only effective for small tumors in early stages of growth. In a later stage of tumor growth, active immunotherapy did not cure any mice, whereas passive immunotherapy was successful in all animals. Reasons for the failure of these LTB to respond to active vaccination with the engineered vaccine may be related to the decreased primary or secondary response we observed in these mice after active immunization. It is suggested that normal antigen-presenting cells expressing the tumor rejection antigen can elicit, in the presence of IL-2, antigen-specific T-cell responses by LTB, and that such T cells may be curative when used in adoptive therapy. We also suggest that the stage of tumor growth and the immune status of LTB more closely simulate the conditions observed in cancer patients.

Abstract
Cooperative integration of laboratory and clinical trial data has provided striking improvement in the treatment of pediatric malignant conditions over the last 2 decades. If attempts are made to individualize therapy to the specific disease and prognostic treatment subgroups for each pediatric malignant condition, the combination of surgery, radiation therapy, and chemotherapy can put the vast majority of patients into a complete clinical remission, with apparent cure for more than half of these patient. Depending on the disease type, treatment failure, when it occurs, is usually the result of recurrent, distant, metastatic disease that is refractory to prior treatment and simultaneously refractory to treatment approaches not yet used for the patient who has had a relapse. The clinical research challenge with these pediatric malignant neoplasms is to identify those children who are harboring microscopic amounts of residual tumor before their relapse and develop effective combined well-tolerated treatment approaches that can be initiated in those patients. These additional treatment approaches should complement rather than duplicate the biologic mechanisms that had been used to initiate remission to eradicate residual tumor without cross resistance. Ongoing laboratory and clinical research approaches are developing and testing the potential of biologic/immunologic therapeutics. The broad application of these principles to clinical oncology will be facilitated by the integrated laboratory-clinical testing that is being accomplished through cooperative pediatric clinical research trials.

Abstract
Engraftment of congenic (BALB/c) or semi-syngeneic (dm2) CD4+ T cell clones into immunodeficient SCID mice was investigated in two experimental systems: the adoptive transfer of Iad-restricted, anti-host-reactive ('self-reactive') CD4+ T cell clones, and the adoptive transfer of OVA-specific CD4+ T cell clones. SCID mice transplanted with 10(4)-10(5) purified BALB/c CD4+ T cells select anti-host-reactive T cells for engraftment. Anti-SCID-reactive T cell clones derived from such preselected CD4+ T cell populations could be successfully engrafted into secondary SCID recipients. In a second series of experiments, Iad-restricted, self-reactive BALB/c CD4+ T cell clones established in long-term culture from unselected, normal BALB/c spleen cell populations were transferred into SCID mice. Not a single clone from this panel could be transplanted into the immunodeficient host. Intravenous injection of OVA-primed dm2 (Ld-) CD4+ T cells into OVA-immunized young SCID (Ld+) mice repopulated the splenic and peritoneal T cell compartment of all transplanted mice. OVA-specific dm2 CD4+ T cells from the spleens of transplanted SCID mice were (sub)cloned under limiting dilution conditions in vitro. Only some of these clones repopulated OVA-immunized SCID recipients after retransplantation in vivo. Serial transfer experiments with a selected OVA-specific dm2 CD4+ T cell clone indicated that the route of cell transfer (i.p., but not i.v.), but not the route of OVA immunization of the host (i.v. or i.p.) were critical for successful engraftment of this clone. Hence, selected CD4+ T cell clones can be successfully engrafted into SCID mice if (i) the population from which clones are derived is preselected in SCID mice, (ii) the in vitro culture period of T cells is restricted to a few months, and (iii) alternative routes of cell transfer are tested. In infectious disease models, protective T cell clones can be identified in vivo using the described system. In addition, the importance of T cells with defined phenotype and effector functions in the pathogenesis of autoimmune disorders can be assessed in this system.

Abstract
The adoptive transfer of antigen-specific T cells to establish immunity is an effective therapy for viral infections and tumors in animal models. The application of this approach to human disease would require the isolation and in vitro expansion of human antigen-specific T cells and evidence that such T cells persist and function in vivo after transfer. Cytomegalovirus-specific CD8+ cytotoxic T cell (CTL) clones could be isolated from bone marrow donors, propagated in vitro, and adoptively transferred to immunodeficient bone marrow transplant recipients. No toxicity developed and the clones provided persistent reconstitution of CD8+ cytomegalovirus-specific CTL responses.

Abstract
Treatment of human cancer with tumour-specific T lymphocytes is limited by the frequent unavailability of autologous tumour to stimulate T-cell growth and by the toxicity associated with high-dose interleukin-2 (IL-2) treatment. In the present study we demonstrate that Bryostatin 1 (B) plus ionomycin (I) can substitute for tumour antigen and activate tumour-bearing hosts' T-cells which provide long-term protection against tumour challenge after adoptive transfer. Lymphocytes obtained from the popliteal lymph nodes (DLN) draining an MCA-105 footpad sarcoma were stimulated with B/I, and then cultured for 7 days with 20 U ml-1 IL-2. This in vitro stimulation protocol consistently expanded cell numbers greater than 20-fold during 7 days. Mice given B/I-stimulated draining lymph node (DLN) cells were protected from specific i.v. tumour challenge for at least 15 weeks after adoptive transfer, even in the absence of IL-2 treatment. Tumour immunity conferred by B/I-activated DLN cells was systemic and independent of host T-cells. However, resistance to tumour challenge was lost when either CD4+ or CD8+ T-cells were depleted in vivo. These studies indicate that DLN cells activated with bryostatin 1 and ionomycin persist long-term in vivo as functional memory cells after adoptive transfer.

Abstract
To try to understand the functional significance of human melanoma-infiltrating lymphocytes (TIL), a clonal analysis of the specificity, T cell receptor (TcR) diversity and activation requirements of these lymphocytes isolated from four different tumors was carried out. Supporting the presence of in vivo primed tumor-specific T lymphocytes in these four tumors, a high frequency of the Cd8+ and CD4+ clones, obtained from the TIL cultured for a few days with recombinant interleukin (rIL)-2 and autologous tumor cells, exhibited a restricted lysis or proliferation in response to the autologous tumor cell line. In contrast, no tumor-specific clone was obtained from freshly extracted TIL, suggesting that the frequency of tumor-specific effectors remained low in these tumors. Only the CD8+ clones lysed the autologous tumor cells and their activity was major histocompatibility complex MHC class I restricted. Significant expansion of CD4+ and CD8+ tumor-specific clones required regular restimulation by autologous melanoma cells but also the addition of exogenous IL-2 and of Epstein-Barr virus-transformed B feeder cells. Five different tumor-specific clones, three CD8+ and two CD4+ clones were identified in a single tumor on the basis of their TcR gene configuration. Together, these data suggest that a spontaneous and diverse immune response, mediated by tumor-specific CD4+ as well as CD8+ T lymphocytes, arises in most MHC-bearing human melanomas but that antigen-MHC complex presentation by tumor cells does not, at least in vitro, allow a significant proliferation of these lymphocytes.

Abstract
Adoptive immunotherapy in humans may be limited by the lack of autologous tumor cells to activate and expand tumor-specific T cells. Pharmacologic manipulation of protein kinase C (PKC) and intracellular calcium may substitute for tumor antigen and stimulate T cells for adoptive immunotherapy. In the present study, we evaluated the ability of the PKC activator Bryostatin 1 (B) plus the calcium ionophore ionomycin (I) to activate lymphocytes obtained from popliteal lymph nodes (DLN) draining an MCA-105 footpad tumor. The adoptive transfer of B/I-stimulated DLN cells eradicated MCA-105 pulmonary metastases. These lymphocytes do not require concomitant IL-2 administration to mediate regression of lung metastases. Three days after intrasplenic injection of tumor cells and splenectomy, mice were given iv injections of B/I-stimulated DLN cells. Adoptive immunotherapy with these cells induced regression of established liver metastases. In an intradermal tumor model, the adoptive transfer of B/I-stimulated MCA-105 DLN cells cured mice of MCA-105 intradermal (id) tumors, but did not induce regression of MCA-206 tumors. Mice cured of MCA-105 id tumors were protected against MCA-105, but not MCA-203, tumor challenge in the footpad 7 weeks after adoptive immunotherapy.

Abstract
The hallmark of chronic myelogenous leukemia is the translocation of the human c-abl protooncogene (ABL) from chromosome 9 to the specific breakpoint cluster region (bcr) of the BCR gene on chromosome 22. The t(9;22)(q34;q11) translocation results in the formation of a BCR-ABL fusion gene that encodes a 210-kDa chimeric protein with abnormal tyrosine kinase activity. The ABL and BCR genes are expressed by normal cells and thus the encoded proteins are presumably nonimmunogenic. However, the joining-region segment of the p210BCR-ABL chimeric protein is composed of unique sequences of ABL amino acids joined to BCR amino acids that are expressed only by malignant cells. The current study demonstrates that the joining region of BCR-ABL protein is immunogenic to murine T cells. Immunization of mice with synthetic peptides corresponding to the joining region elicited peptide-specific, CD4+, class II major histocompatibility complex-restricted T cells. The BCR-ABL peptide-specific T cells recognized only the combined sequence of BCR-ABL amino acids and not BCR or ABL amino acid sequences alone. Importantly, the BCR-ABL peptide-specific T cells could recognize and proliferate in response to p210BCR-ABL protein. The response of peptide-specific T cells to protein demonstrated that p210BCR-ABL can be processed by antigen-presenting cells so that the joining segment is bound to class II major histocompatibility complex molecules in a configuration similar to that of the immunizing peptide and in a concentration high enough to stimulate the antigen-specific T-cell receptor. Thus, BCR-ABL protein represents a potential tumor-specific antigen related to the transforming event and shared by many individuals with chronic myelogenous leukemia.

Abstract
Gut-associated lymphoid tissues (GALT) from aged mice enterically immunized with Mycobacterium paratuberculosis protoplasmic antigen show hyperreactive humoral immune responses; this hyperresponsiveness can be corrected to a considerable extent, but not entirely, by systemic administration of interleukin 2 (IL 2) alone. The aim of the present study was to determine further whether the hyperreactivity in the antigen-specific humoral immune responses in aged GALT could be fully restored by adoptive transfer of in vitro expanded antigen-specific IL 2-dependent helper (CD4+VV-) T cells from GALT in conjunction with recombinant IL 2 administration. The results show that the age-associated hyperresponsiveness in gut mucosal antigen-specific humoral immune responses can be entirely corrected by adoptive transfer with the antigen-specific GALT T helper cells together with in vivo IL 2 administration. The mechanism of this restoration involves reversal of the decline in antigen-specific CD8+ suppressor T cell functions in aged GALT.

Abstract
In previous reports, we demonstrated that adoptively transferred T cells homed to the tumor site (among other sites) and that amplification of immune responses occurred in situ leading to the generation of cytotoxic CD8+ tumor-infiltrating lymphocytes (TIL) and macrophages. The present report extends these findings and shows that following adoptive immunotherapy (AIT) of mice bearing the immunogenic transplanted methylcholanthrene-induced rhabdomyosarcoma (MCA/76-9) there was a differential expansion of CD4+ and CD8+ TIL, the numbers peaking on days 6 and 8, respectively. At this time, CD8+ TIL accounted for the majority of Thy-1+ cells. Northern analyses of RNA extracted from positively selected (by panning) Thy-1+, CD8+ and CD4+ TIL isolated 8 days after AIT indicated the following: in five separate experiments, CD4+ cells expressed three- to sixfold more interleukin (IL)2 mRNA and six- to eightfold more IL6 mRNA than CD8+ cells, while CD8+ TIL expressed three- to sixfold more IL2 receptor (IL2R) mRNA and four- to sixfold more interferon-gamma mRNA than CD4+ cells. TIL cultured in 10% fetal bovine serum failed to release IL2 over a 24-h period, whereas both IL6 and interferon-gamma activities were demonstrable. The level of IL2R mRNA expression was reflected by a vigorous proliferative response of CD8+ TIL to exogenous recombinant IL2 and only a low response by CD4+ cells suggesting that most of the CD4+ TIL were in the resting stage. This was confirmed when it was shown that the incubation of panned CD4+ TIL with IL2 supplemented with irradiated spleen cells and "spent" 76-9 tumor culture supernatant (as a source of antigen) induced expansion of TIL resulting in a population consisting of greater than 90% CD4+ TIL. The overall data suggest that the relatively deactivated state of the CD4+ TIL at this particular time reflects the status of the rejection process in terms of the absence or low concentration of stimulating tumor-associated antigen.

Abstract
A graft versus leukaemia (GvL) effect makes a significant contribution to the lower risk of relapse seen in patients after BMT compared with patients receiving chemotherapy alone. Both T cell-dependent and T cell-independent effectors of GvL exist, and both may play an important role in the elimination of minimal residual disease after BMT. There is evidence that GvL activity may be separable from GvHD either by identifying T cell clones recognizing specific leukaemia antigens or by using immunomodulatory drugs or cytokines to enhance T cell-independent GvL mechanisms which operate without alloreactivity and therefore without concomitant exacerbation of GvHD. These approaches should improve survival after both autologous and allogeneic BMT.

Abstract
A CD8+ clone, identified by its T-cell receptor gamma- and beta-gene configuration, was shown to preferentially develop, in the bulk culture of melanoma tumor-infiltrating lymphocytes with recombinant interleukin 2 after 1 month. Thirteen CD8+ clones were obtained by limiting dilution culture of tumor-infiltrating lymphocytes from 43-days old culture. Four of these clones, analyzed for T-cell receptor rearrangements, exhibited exactly the same T-cell receptor gene pattern as tumor-infiltrating lymphocytes from the bulk culture, showing, therefore, that all the CD8+ clones were subclones. All the 13 CD8+ subclones were strongly cytotoxic for autologous melanoma cells but did not kill K562. A more complete cytotoxicity analysis showed that the clones did not kill autologous fibroblasts or Con A blasts or allogeneic tumor targets. Furthermore, specific killing was inhibited by monoclonal antibodies against CD3, CD8, T-cell receptors alpha beta, and class I major histocompatibility complex antigens indicating that effector-to-target cell recognition was mediated through the T-cell receptor in a major histocompatibility complex-restricted fashion. These data showed that human melanoma-specific cytotoxic T lymphocytes can be obtained from melanoma TIL and that a single cytotoxic T lymphocyte clone can be expanded to more than 10(10) cells without a loss of autotumor specificity.
