Abstract
Tumor hypoxia-driven accumulation of extracellular adenosine was shown to facilitate tumor evasion by engaging the immunosuppressive, intracellular cAMP-elevating A2 adenosine receptors (A2R) on tumor-reactive effector T cells, but there remains a need for careful evaluation of the limiting factors and properties of A2R blockade-enabled antitumor immunity. In studies of A2AR and/or A2BR gene-deficient mice, we found that A2AR deletion-but not A2BR deletion-liberates endogenous CD8+ T cell antitumor immunity against weakly immunogenic MCA205 sarcomas. Studies of adoptively transferred A2AR-/-, A2BR-/-, or A2AR-/-/A2BR-/- tumor-reactive T cells confirmed that immunosuppression in the tumor microenvironment was mediated by A2AR on CD8+ T cells. Treatment with A2AR antagonist mimicked A2AR gene deletion in adoptive T cell immunotherapy. This therapeutic benefit of targeting A2AR was independent of the anatomical location of tumor growth. The enhanced antitumor reactivity also led to the eradication of established intracranial tumors, which was associated with mouse survival and the maintenance of long-lasting, tumor-specific immunological memory. The blockade of the A2AR on adoptively transferred T cells by synthetic A2AR antagonist led to higher levels of IFN-γ secretion by tumor-infiltrating CD8+ T cells. These data clarify the mechanism of hypoxia-driven immunosuppression in the tumor microenvironment by A2AR on tumor-reactive CD8+ T cells and show that selective A2AR antagonists can be effective in improving the outcomes of T cell-based immunotherapies. Demonstration of the T cell dose dependency of tumor rejection points to a major limitation of current cancer immunotherapies, in which the presence of sufficient numbers of tumor-reactive T cells in a patient is not known.

Abstract
Many cancers both evoke and subvert endogenous anti-tumor immunity. However, immunosuppression can be therapeutically reversed in subsets of cancer patients by treatments such as checkpoint inhibitors or Toll-like receptor agonists (TLRa). Moreover, chemotherapy can leukodeplete immunosuppressive host elements, including myeloid-derived suppressor cells (MDSCs) and regulatory T-cells (Tregs). We hypothesized that chemotherapy-induced leukodepletion could be immunopotentiated by co-administering TLRa to emulate a life-threatening infection. Combining CpG (ODN 1826) or CpG+poly(I:C) with cyclophosphamide (CY) resulted in uniquely well-tolerated therapeutic synergy, permanently eradicating advanced mouse tumors including 4T1 (breast), Panc02 (pancreas) and CT26 (colorectal). Definitive treatment required endogenous CD8+ and CD4+ IFNγ-producing T-cells. Tumor-specific IFNγ-producing T-cells persisted during CY-induced leukopenia, whereas Tregs were progressively eliminated, especially intratumorally. Spleen-associated MDSCs were cyclically depleted by CY+TLRa treatment, with residual monocytic MDSCs requiring only continued exposure to CpG or CpG+IFNγ to effectively attack malignant cells while sparing non-transformed cells. Such tumor destruction occurred despite upregulated tumor expression of Programmed Death Ligand-1, but could be blocked by clodronate-loaded liposomes to deplete phagocytic cells or by nitric oxide synthase inhibitors. CY+TLRa also induced tumoricidal myeloid cells in naive mice, indicating that CY+TLRa's immunomodulatory impacts occurred in the complete absence of tumor-bearing, and that tumor-induced MDSCs were not an essential source of tumoricidal myeloid precursors. Repetitive CY+TLRa can therefore modulate endogenous immunity to eradicate advanced tumors without vaccinations or adoptive T-cell therapy. Human blood monocytes could be rendered similarly tumoricidal during in vitro activation with TLRa+IFNγ, underscoring the potential therapeutic relevance of these mouse tumor studies to cancer patients.

Abstract
Effective adoptive immunotherapy has proved elusive for many types of human cancer, often due to difficulties achieving robust expansion of natural tumor-specific T-cells from peripheral blood. We hypothesized that antigen-driven T-cell expansion might best be triggered in vitro by acute activation of innate immunity to mimic a life-threatening infection. Unfractionated peripheral blood mononuclear cells (PBMC) were subjected to a two-step culture, first synchronizing their exposure to exogenous antigens with aggressive surrogate activation of innate immunity, followed by γ-chain cytokine-modulated T-cell hyperexpansion. Step 1 exposure to GM-CSF plus paired Toll-like receptor agonists (resiquimod and LPS), stimulated abundant IL-12 and IL-23 secretion, as well as upregulated co-stimulatory molecules and CD11c expression within the myeloid (CD33+) subpopulation. Added synthetic long peptides (>20aa) derived from widely expressed oncoproteins (MUC1, HER2/neu and CMVpp65), were reliably presented to CD4+ T-cells and cross-presented to CD8+ T-cells. Both presentation and cross-presentation demonstrated proteasomal and Sec61 dependence that could bypass the endoplasmic reticulum. Step 2 exposure to exogenous IL-7 or IL-7+IL-2 produced selective and sustained expansion of both CD4+ and CD8+ peptide-specific T-cells with a predominant interferon-γ-producing T1-type, as well as the antigen-specific ability to lyse tumor targets. Other γ-chain cytokines and/or combinations were initially proliferogenic, but followed by a contractile phase not observed with IL-7 or IL-7+IL-2. Regulatory T-cells were minimally propagated under these culture conditions. This mechanistically rational culture sequence, effective even for unvaccinated donors, enables rapid preparation of T-cells recognizing tumor-associated antigens expressed by the majority of human cancers, including pancreatic cancers, breast cancers and glioblastomas.

Abstract
OBJECTIVE: The goal of this study was to determine whether CD40 ligation of antigen presenting cells (APCs) enhances the anti-tumor effector function of tumor draining lymph node (TDLN) T lymphocytes in an adoptive immunotherapy model. STUDY DESIGN: MCA 205 TDLNs were culture activated both in the presence and absence of a stimulatory anti-CD40 monoclonal antibody (mAb) and effector cell phenotype, cytokine secretion in vitro and therapeutic efficacy in vivo were compared. RESULTS: Anti-CD40 mAb induced upregulation of APC cell surface activation markers that promoted generation of T cells that demonstrated an increase in tumor-specific IFN-gamma secretion and a statistically significant reduction in the number of pulmonary tumors (p< 0.01) after adoptive transfer. CONCLUSION: CD40 ligation of APCs in vitro results in the generation of T cells with enhanced effector function against established pulmonary tumors in vivo. SIGNIFICANCE: These findings have direct implications in the development of effective T cell-based immunotherapy of malignant conditions in human beings.

Abstract
Effective cell-mediated antitumor immunity requires the activation of tumor-reactive T cells and the trafficking of activated T cells to tumor sites. These processes involve the extravasation of lymphocytes from the blood and lymphatics, and their homing to lymph nodes and tumors. L-selectin (CD62L) is an important molecule in these processes. It directs naive lymphocytes to peripheral lymph nodes where they become activated and it traffics naive lymphocytes to inflammatory environments, such as tumors. Individuals with advanced cancer are immune suppressed due to myeloid-derived suppressor cells (MDSC), a population of immature myeloid cells that accumulate to high levels in response to tumor-secreted and proinflammatory factors. We now demonstrate that the reduction in T cell levels of L-selectin that is commonly seen in individuals with cancer inversely correlates with MDSC levels. Three lines of evidence demonstrate that MDSC directly down-regulate L-selectin on naive T cells: 1) naive T cells cocultured with tumor-induced MDSC have reduced L-selectin; 2) T cells in tumor-free aged mice with elevated levels of MDSC have reduced L-selectin, and 3) peritoneal exudate T cells of tumor-free mice treated with plasminogen activator urokinase to elevate MDSC have reduced levels of L-selectin. MDSC are likely to down-regulate L-selectin through their plasma membrane expression of ADAM17 (a disintegrin and metalloproteinase domain 17), an enzyme that cleaves the ectodomain of L-selectin. Therefore, MDSC down-regulate L-selectin levels on naive T cells, decreasing their ability to home to sites where they would be activated. This is another mechanism by which MDSC inhibit antitumor immunity.

Abstract
The clinical outcomes of dendritic cell (DC)-based immunotherapy remain disappointing, with DCs often displaying a tenuous capacity to complete maturation and DC1 polarization in the tumor host. Surprisingly, we observed that the capacity for successful DC1 polarization, including robust IL12p70 production, could be regulated by STAT-dependent events even prior to DC differentiation. Exposure of CD34(pos) cells to single-agent granulocyte-macrophage colony-stimulating factor (GMCSF) induced multilineage, STAT5-dependent differentiation, including DCs that failed to mature in the absence of further exogenous signals. In contrast, Flt3L induced nearly global differentiation of CD34(pos) cells into spontaneously maturing DCs. IL-6 synergized with Flt3L to produce explosive, STAT3-dependent proliferation of phenotypically undifferentiated cells that nevertheless functioned as committed DC1 precursors. Such precursors not only resisted many tumor-associated immunosuppressants, but also responded to tumor contact or TGFbeta with facilitated DC maturation and IL12p70 production, and displayed a superior capacity to reverse tumor-induced T-cell tolerance. GMCSF preempted Flt3L or Flt3L plus IL-6 licensing by blocking STAT3 activation and promoting STAT5-dependent differentiation. Paradoxically, following overt DC differentiation, STAT5 enhanced whereas STAT3 inhibited DC1 polarization. Therefore, nonoverlapping, sequential activation of STAT3 and STAT5, achievable by sequenced exposure to Flt3L plus IL-6, then GMCSF, selects for multilog expansion, programming, and DC1 polarization of tumor-competent DCs from CD34(pos) cells.

Abstract
Regulatory T cells (Treg) play important roles in immune system homeostasis, and may also be involved in tumor immunotolerance by suppressing Th1 immune response which is involved in anti-tumor immunity. We have previously reported that immunization with attenuated activated autologous T cells leads to enhanced anti-tumor immunity and upregulated Th1 responses in vivo. However, the underlying molecular mechanisms are not well understood. Here we show that Treg function was significantly downregulated in mice that received immunization of attenuated activated autologous T cells. We found that Foxp3 expression decreased in CD4+CD25+ T cells from the immunized mice. Moreover, CD4+CD25+Foxp3+ Treg obtained from immunized mice exhibited diminished immunosuppression ability compared to those from naïve mice. Further analysis showed that the serum of immunized mice contains a high level of anti-CD25 antibody (about 30 ng/ml, p<0.01 vs controls). Consistent with a role of anti-CD25 response in the downregulation of Treg, adoptive transfer of serum from immunized mice to naïve mice led to a significant decrease in Treg population and function in recipient mice. The triggering of anti-CD25 response in immunized mice can be explained by the fact that CD25 was induced to a high level in the ConA activated autologous T cells used for immunization. Our results demonstrate for the first time that immunization with attenuated activated autologous T cells evokes anti-CD25 antibody production, which leads to impeded CD4+CD25+Foxp3+ Treg expansion and function in vivo. We suggest that dampened Treg function likely contributes to enhanced Th1 response in immunized mice and is at least part of the mechanism underlying the boosted anti-tumor immunity.

Abstract
The HER-2/neu oncogene has >25 HLA epitopes, yet only one FVB/N mouse CD8(+) T-cell epitope has been mapped to date. This epitope has been termed the immunodominant epitope for the FVB/N mouse, but we propose that the vaccination strategy determines the dominance of epitopes. Using a series of overlapping peptides, we have mapped another CD8(+) T-cell epitope that emerges in the FVB/N mouse following vaccination with Listeria monocytogenes-based vaccines that express fragments of HER-2/neu. Following the identification of this novel H-2K(q)-restricted epitope, we sought to compare the T-cell response to this epitope with the previously identified PDSLRDLSVF epitope. This newly identified epitope and the previously identified epitope lie within fragments contained in different vaccines, the PDSLRDLSVF epitope in Lm-LLO-EC2 and the newly identified PYNYLSTEV epitope in Lm-LLO-EC1; thus, it has been possible to compare the responses of these epitopes independent of any competing response between the epitopes. CTL analysis of individual peptide-pulsed target cells and intracellular cytokine stain for IFN-gamma produced by splenocytes from Lm-LLO-EC1 compared with Lm-LLO-EC2 vaccinated FVB/N mice shows that there is no difference between the responses generated to either of these epitopes. We also show that the avidity of the CD8(+) T cells for either of these epitopes is similar based on the concentration of peptide necessary to mediate similar levels of lysis of target cells. In addition, HER-2/neu DNA vaccination followed by CTL analysis further showed that both of these peptides can emerge as epitopes.

Abstract
The human high m.w.-melanoma-associated Ag (HMW-MAA) is an attractive target for the immunotherapy of melanoma, due to its relatively high expression in a high percentage of melanoma lesions and its restricted distribution in normal tissues. Active immunization with HMW-MAA mimics has been previously shown to induce a HMW-MAA-specific, T cell-dependent Ab response associated with an apparent clinically beneficial effect in advanced melanoma patients. Although T cells play an important role in controlling tumor growth, only limited information is available to date about the induction of HMW-MAA-specific CTL. In this report, we show that immunization of HLA-A2/K(b) transgenic mice with HMW-MAA cDNA-transfected syngeneic dendritic cells elicited a CD8(+) CTL response specific for HMW-MAA peptides with HLA-A2 Ag-binding motifs. The elicited CTL lysed HLA-A2(+)HMW-MAA(+) melanoma cells in vitro, and mouse HLA-A2/K(b) cells pulsed with HMW-MAA-derived peptides in vitro and in vivo. Although this CTL response could be generated in the absence of CD4(+) T cell help, harnessing CD4(+) T cell help in a noncognate Ag-specific manner with the polyclonal activator staphylococcal enterotoxin A augmented the CTL response. These results imply that dendritic cell-based immunization, in combination with CD4(+) T cell help, represents an effective strategy to implement T cell-based immunotherapy targeting HMW-MAA in patients with HMW-MAA-bearing tumors.

Abstract
We demonstrated previously that tumor lysate-pulsed dendritic cells (TP-DC) could mediate a specific and long-lasting antitumor immune response against a weakly immunogenic breast tumor during early lymphoid reconstitution. The purpose of this study was to examine the potential therapeutic efficacy of bone marrow transplants from TP-DC-vaccinated donors. In 2 aggressive metastatic models, bone marrow transplantation with donor bone marrow cells from TP-DC-immunized mice mediated a tumor-specific immune response in the recipient, and this caused regressions of preexisting tumor metastases. After vaccination with TP-DC, donors harbored increased numbers of both activated CD4+ and CD8+ T-cell populations in the bone marrow. Adoptive transfer of T cells purified from the bone marrow of TP-DC-vaccinated mice led to a reduction in preestablished lung metastases, whereas depletion of T cells from bone marrow abolished this effect. By using T cells derived from the bone marrow of TP-DC-vaccinated major histocompatibility complex class I and class II knockout mice, the effector cells required for the observed antitumor effect were determined to be major histocompatibility complex class I-restricted CD8+ T cells. Additionally, the tumor burden in TP-DC-immunized transplant recipients could be reduced further by repetitive TP-DC immunizations after bone marrow transplantation. Collectively, these results demonstrate an important therapeutic role of bone marrow from TP-DC-immunized donors and raise the potential for this approach in patients with advanced cancer.

Abstract
T cell-mediated cancer immunotherapy is dose dependent and optimally requires participation of antigen-specific CD4+ and CD8+ T cells. Here, we isolated tumor-sensitized T cells and activated them in vitro using conditions that led to greater than 108-fold numerical hyperexpansion of either the CD4+ or CD8+ subset while retaining their capacity for in vivo therapeutic efficacy. Murine tumor-draining lymph node (TDLN) cells were segregated to purify the CD62Llow subset, or the CD4+ subset thereof. Cells were then propagated through multiple cycles of anti-CD3 activation with IL-2 + IL-7 for the CD8+ subset, or IL-7 + IL-23 for the CD4+ subset. A broad repertoire of TCR Vbeta families was maintained throughout hyperexpansion, which was similar to the starting population. Adoptive transfer of hyper-expanded CD8+ T cells eliminated established pulmonary metastases, in an immunologically specific fashion without the requirement for adjunct IL-2. Hyper-expanded CD4+ T cells cured established tumors in intracranial or subcutaneous sites that were not susceptible to CD8+ T cells alone. Because accessibility and antigen presentation within metastases varies according to anatomic site, maintenance of a broad repertoire of both CD4+ and CD8+ T effector cells will augment the overall systemic efficacy of adoptive immunotherapy.

Abstract
BACKGROUND Antigen-specific T cells undergoing clonal expansion share common rearrangements of the variable complementary determining region 3 (CDR3) of the T-cell receptor (TCR), which can be identified using polymerase chain reaction-based V beta (VB) spectratyping. The purpose of this study was to determine whether CDR3 spectratyping identifies clonal expansion within tumor-draining lymph node (TDLN) subpopulations with antitumor therapeutic activity. METHODS Recently sensitized T cells from 4T1 murine mammary carcinoma TDLN were fractionated based on CD62L (L-selectin) surface expression before RNA isolation and culture. L-selectinlow and L-selectinhigh TDLN were analyzed for T-cell receptor usage by immunophenotyping and CDR3 spectratyping, and then culture activated with anti-CD3/IL-2 to assess therapeutic efficacy after adoptive transfer. RESULTS Adoptive transfer experiments confirmed that mice treated with culture-activated L-selectinlow TDLN cells exhibited delayed subcutaneous tumor growth and prolonged survival as compared to control or L-selectinhigh-treated mice (P < .01). CDR3 spectratyping demonstrated oligoclonal skewing of the CDR3 regions within several VB families including VB3, VB5.2, and VB17 in L-selectinlow but not in L-selectinhigh TDLN. Although fluorescence-activated cell sorter analysis demonstrated the highest percentage of cells expressing VB13 usage in both populations, CDR3 spectratyping did not identify the presence of clonal expansion. CONCLUSIONS These data suggest that CDR3 spectratyping may be useful in identifying T cells undergoing clonal expansion that demonstrate antitumor therapeutic activity.

Abstract
To determine the mechanisms by which adoptive immunotherapy could reduce lethality to acute myelogenous leukemia (AML), a novel technique was developed to track both leukemic blasts and adoptively transferred cytotoxic T cells (CTLs) independently and simultaneously in mice. To follow the fate of ex vivo generated anti-AML-reactive CTLs, splenocytes obtained from enhanced green fluorescent protein transgenic mice were cocultured with AML lysate-pulsed dendritic cells, which subsequently were expanded by exposure to anti-CD3/CD28 monoclonal antibody-coated magnetic microspheres. To track AML cells, stable transfectants of C1498 expressing DsRed2, a red fluorescent protein, were generated. Three factors related to CTLs correlated with disease-free survival: (a). CTL L-selectin expression. L-Selectin high fractions resulted in 70% disease-free survival, whereas L-selectin low-expressing CTLs resulted in only 30% disease-free survival. (b). Duration of ex vivo expansion (9 versus 16 days). Short-term expanded CTLs could be found at high frequency in lymphoid organs for longer than 4 weeks after transfer, whereas long-term expanded CTLs were cleared from the system after 2 weeks. Duration of expansion correlated inversely with L-selectin expression. (c). CTL dose. A higher dose (40 versus 5 x 10(6)) resulted in superior disease-free survival. This survival advantage was achieved with short-term expanded CTLs only. The site of treatment failure was mainly the central nervous system where no CTLs could be identified at AML sites.

Abstract
Adoptive transfer of tumor-specific effector T cells induces regression of advanced tumors and induces a long term memory response; however, the origin of this response has not been clearly defined. In this study Thy1.2+ mice bearing advanced MCA-205 tumors were treated with sublethal total body irradiation, followed by adoptive transfer of congenic Thy1.1+ T cells that had been sensitized to tumor in vivo and then activated ex vivo with anti-CD3, IL-2, and IL-7. Splenocytes were recovered >140 days after the initial therapy, and the L-selectinlow memory cell subset was separated into host Thy1.2+ and transferred Thy1.1+ cells and restimulated ex vivo. Both adoptively transferred Thy1.1+ cells as well as reconstituted host Thy1.2+ cells could specifically eliminate MCA-205 pulmonary metastases. Interestingly, hosts with partial responses followed by tumor recurrence nevertheless harbored memory cells that could be isolated and numerically amplified ex vivo to regenerate potent effector function. Memory cells were recovered after adoptive transfer into lymphodepleted nontumor-bearing hosts, indicating that they were not dependent on continued Ag exposure. These experiments establish that rapid ex vivo expansion of tumor Ag-primed T cells does not abrogate their capacity to become long-lived memory cells. Moreover, immune-mediated tumor regression coincident with lymphoid reconstitution produces another wave of host memory cells. These data suggest an approach to rescuing antitumor immune function even in hosts with long-standing progressive tumor through restorative ex vivo activation.

Abstract
Antigen presentation by dendritic cells (DCs) has the potential to elicit therapeutic immune responses against malignant tumors. One strategy utilizing DC-tumor fusion hybrids as cancer vaccine is particularly attractive because of polyclonal presentation of a diverse array of unaltered tumor antigens. We have recently developed a large-scale electrofusion technique for generating DC-tumor heterokaryons and demonstrated their superb immunogenicity. Here, employing the weakly immunogenic MCA205 sarcoma, a single vaccination with electrofusion hybrids eradicated tumors established in the lung, skin, and brain. Immunotherapy required intra-lymphoid vaccine delivery and co-administration of adjuvants such as OX-40R antibody. Tumor eradication was immunologically specific and involved the participation of both CD4 and CD8 T cells. Consistent with DC's functionality of MHC-restriction, the use of syngeneic DCs for fusion was an obligatory requirement. Fusion with allogeneic DCs completely lacked therapeutic effects. These findings provide a strong impetus for treating cancer patients with similarly generated DC-tumor hybrids.

Abstract
Dendritic cells (DCs) loaded with antigens can effectively stimulate host immune responses to syngeneic tumors, but there is considerable controversy as to which forms of antigen-loading are most immunogenic. Here, the authors compared immunotherapeutic reactivities of DCs loaded with a variety of antigen preparations. Because DC maturation stages affect their capacities of antigen processing and presentation, two DC populations were used for the current analysis: in vivo Flt-3 ligand-induced mature DCs and in vitro bone marrow-derived DCs, which were less mature. To facilitate a direct comparison, the LacZ gene-transduced B16 melanoma model system was used, where beta-galactosidase served as the surrogate tumor-rejection antigen. DC loading strategies included pulsing with the beta-galactosidase protein, H-2K restricted peptide, tumor cell lysate, and irradiated tumor cells and fusion of DCs with tumor cells. Our results demonstrated that electrofusion of DCs and tumor cells generated a therapeutic vaccine far superior to other methods of DC loading. For the treatment of 3-day established pulmonary tumor nodules, a single intranodal vaccination plus IL-12 resulted in a significant reduction of metastatic nodules, while other DC preparations were only marginally effective. Immunotherapy mediated by the fusion cells was tumor antigen-specific. Consistent with their therapeutic activity, fusion hybrids were the most potent stimulators to induce specific IFN-gamma secretion from immune T cells. Furthermore, fusion cells also stimulated a small amount of IL-10 production from immune T cells. However, this IL-10 secretion was also induced by other DC preparations and did not correlate with in vivo therapeutic reactivity.

Abstract
Activated T cells with down-regulated L-selectin expression (L-sel(-)) from tumor-draining lymph nodes represent a potent source of specific immune effectors in adoptive immunotherapy. Using congenic pairs of mice and carboxyfluorescein diacetate succinimidyl ester-labeled L-sel(-) T cells, the current study analyzed in vivo proliferation of transferred cells. In the lung of MCA205 tumor-bearing mice, 6% or 0.3 x 10(6) of the 5 x 10(6) donor cells were identified 24 h after transfer. Vigorous proliferation of donor cells was evident on day 2, reaching a maximum on day 6. The proliferation was tumor-specific and CD4 T cells divided with greater magnitude than CD8 cells. Successful adoptive immunotherapy also required sublethal whole-body irradiation (WBI) of the recipient. WBI exerted its effects on facilitating specific T cell proliferation at the tumor site. Taken together, our results demonstrate that adoptively transferred T cells undergo extensive proliferation in response to the tumor and this response is associated with therapeutic efficacy.

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
Tumor-specific effector T cells (T(E)) are naturally sensitized within the L-selectin(low) (CD62L(low)) fraction of tumor-draining lymph nodes (TDLN). Whether isolated from day 9 (D9) or day 12 (D12) TDLN, 5 million L-selectin(low) T(E) could be culture activated and adoptively transferred to achieve complete rejection of established intradermal, pulmonary, and brain tumors. Surprisingly, although 25 million unfractionated T cells from D9 TDLN were equally effective, even 100 million unfractionated T cells from D12 TDLN seldom prevented lethal intradermal tumor progression, despite a pronounced therapeutic excess of T(E). This highly reproducible treatment failure was due to cotransfer of tumor-induced, L-selectin(high) suppressor T cells (T(S)) which were also present in D12 TDLN. In contrast, D9 TDLN and normal spleens lacked L-selectin(high) T(S). Only those L-selectin(high) D12 TDLN T cells that down-regulated L-selectin during culture activation were suppressive in vivo and in vitro, and, like L-selectin(low) T(E), trafficked promptly into tumors following i.v. administration. This is the first demonstration that adoptive immunotherapy can fail as a direct result of passenger T(S) that share certain phenotypic and trafficking features of T(E), even when otherwise curative doses of T(E) have been administered. Furthermore, in contrast to recently described CD4(+)CD25(+) T(S) and plasmacytoid dendritic cell-activated T(S), tumor-induced L-selectin(high) T(S) prevent tumor rejection via blockade of sensitized, activated T(E) rather than via afferent blockade.

Abstract
Tumor-draining lymph nodes (TDLN) contain sensitized T cells with the phenotype CD62 L-selectin(low) (CD62L(low)) that can be activated ex vivo with anti-CD3 mAb and IL-2 to acquire potent dose-dependent effector function manifested upon adoptive transfer to secondary tumor-bearing hosts. In this study advanced tumor models were used as a stringent comparison of efficacy for the CD62L(low) subset, comprising 5-7% of the TDLN cells, vs the total population of TDLN cells following culture in high dose IL-2 (100 U/ml). During the 9-day activation period the total number of CD8+ T cells increased 1500-fold, with equivalent proliferation in the CD62L(low) vs the total TDLN cell cultures. Adoptive transfer of activated CD62L(low) cells eliminated 14-day pulmonary metastases and cured 10-day s.c. tumors, whereas transfer of maximally tolerated numbers of total TDLN cells was not therapeutic. Despite their propagation in a high concentration of IL-2, the hyperexpanded CD62L(low) subset of TDLN cells functioned in vivo without exogenous IL-2, and CD8+ T cells demonstrated relative helper independence. Moreover, the anti-tumor response was specific for the sensitizing tumor, and long term memory was established. The facile enrichment of tumor-reactive TDLN T cells, based on the CD62L(low) phenotype, circumvents the need for prior knowledge of the relevant tumor Ags. Coupling the isolation of pre-effector T cells with rapid ex vivo expansion to >3 logs could overcome some of the shortcomings of active immunotherapy or in vivo cytokine treatment, where selective robust expansion of effector cells has been difficult to achieve.

Abstract
Dendritic cells (DCs) are potent antigen-presenting cells capable of inducing strong immune responses to weak tumor-associated antigens. Among various DC-based approaches, cancer immunotherapy with DC-tumor fusion hybrids offers advantages of polyclonal stimulation of a diverse array of tumor antigens. However, prevalent fusion methods using chemical fusogens such as polyethylene glycol often result in toxicity and low fusion efficiency. In this article, we describe an electrofusion technique, applicable to processing large numbers of cells with consistent and high fusion efficiency. Generation of fusion hybrids was verified by unequivocal experimental evidence. In animal models, fusion hybrids expressed the mature DC-like phenotype. They stimulated both CD4 and CD8 tumor-specific T cells to secrete interferon-gamma in vitro. In immunotherapy, a single vaccination with DC-tumor fusion cells along with interleukin-12 as an adjuvant eradicated tumors established in the skin nd lung. These results provide an impetus for treating cancer patients with similarly generated cells.

Abstract
Recent studies have identified a unique population of CD4+CD25+ regulatory T cells that is crucial for the prevention of spontaneous autoimmune diseases. Further studies demonstrated that depletion of CD4+CD25+ T cells enhances immune responses to nonself antigens. Because immune responses to malignant tumors are weak and ineffective, depletion of regulatory T cells has been reported to result in tumor regression. In the current study, using the weakly immunogenic MCA205 sarcoma and the poorly immunogenic B16/BL6/D5 (D5) melanoma, depletion of CD4+CD25+ T cells by the administration of anti-CD25 monoclonal antibodies (mAb), PC61 induced some tumor growth retardation, but all mice eventually succumbed to tumors. In our laboratory, immunotherapy by the transfer of tumor-immune T cells has demonstrated potent antitumor effects. A reliable source of tumor-reactive T cells has been lymph nodes (LN) draining progressive tumors. Therapeutic effector T cells can be generated by in vitro activation of draining LN cells with anti-CD3 mAb followed by culture in interleukin-2. In this system, PC61 mAb depletion of CD4+CD25+ T cells before or on day 8 of tumor growth resulted in increased sensitization in the draining LN. The therapeutic efficacy of activated tumor-draining LN cells from mAb depleted mice increased approximately three fold while maintaining specificity when tested in adoptive immunotherapy of established pulmonary metastases. Specific interferon-gamma secretion by LN T cells from mice treated with PC61 mAb 1 day before tumor inoculation increased significantly. However, this increase was not demonstrated with LN T cells from mice treated on day 8 despite their enhanced therapeutic reactivities. Our results indicate that although the antitumor immunity enhanced by the depletion of CD4+CD25+ T cells is insufficient to eradicate tumors, it augments the sensitization of immune T cells in the draining LN, thus, facilitating adoptive immunotherapy.

Abstract
CD4+ T cells are crucial to the development of CD8+ T cell responses against hepatocytes infected with malaria parasites. In the absence of CD4+ T cells, CD8+ T cells initiate a seemingly normal differentiation and proliferation during the first few days after immunization. However, this response fails to develop further and is reduced by more than 90%, compared to that observed in the presence of CD4+ T cells. We report here that interleukin-4 (IL-4) secreted by CD4+ T cells is essential to the full development of this CD8+ T cell response. This is the first demonstration that IL-4 is a mediator of CD4/CD8 cross-talk leading to the development of immunity against an infectious pathogen.

Abstract
Therapeutic efficacy of adoptive immunotherapy of malignancies is proportional to the number of effector T cells transferred. Traditionally, exogenous IL-2 treatment has been used to promote the survival and function of transferred cells. Recently, we described the therapeutic effects of in vivo ligation of the costimulatory receptor, OX-40R, on activated T cells during early tumor growth. In this study, we examined the effects of IL-2 and OX-40R mAb on adoptive immunotherapy of advanced tumors. For treatment of 10-day 3-methylcholanthrene 205 pulmonary metastases, systemic transfer of 50 x 10(6) activated tumor-draining lymph node T cells resulted in >99% reduction of metastatic nodules. With either IL-2 or OX-40R mAb conjunctional treatment, only 20 x 10(6) cells were required. Advanced 10-day 3-methylcholanthrene 205 intracranial tumors could be cured by the transfer of 15 x 10(6) L-selectin(low) T cells derived from draining lymph nodes. In this situation, IL-2 administration inhibited therapeutic effects of the transferred cells. By contrast, 5 x 10(6) T cells were sufficient to cure all mice if OX-40R mAb was administrated. Studies on trafficking of systemically transferred T cells revealed that IL-2, but not OX-40R mAb, impeded tumor infiltration by T cells. Tumor regression required participation of both CD4 and CD8 T cells. Because only CD4 T cells expressed OX-40R at cell transfer, direct CD4 T cell activation is possible. Alternatively, OX-40R might be up-regulated on transferred T cells at the tumor site, rendering them reactive to the mAb. Our study suggests OX-40R mAb to be a reagent of choice to augment T cell adoptive immunotherapy in clinical trials.

Peng L, Krauss JC, Plautz GE, Mukai S, Shu S, Cohen PA. T cell-mediated tumor rejection displays diverse dependence upon perforin and IFN-gamma mechanisms that cannot be predicted from in vitro T cell characteristics. JOURNAL OF IMMUNOLOGY (BALTIMORE, MD. : 1950) 2000; 165:7116-24.

Abstract
Experimental pulmonary metastases have been successfully treated by adoptive transfer of tumor-sensitized T cells from perforin knockout (KO) or Fas/APO-1 ligand(KO) mice, suggesting a prominent role for secretion of cytokines such as IFN-gamma. In the present study we confirmed that rejection of established methylcholanthrene-205 (MCA-205) pulmonary metastases displayed a requirement for T cell IFN-gamma expression. However, this requirement could be obviated by transferring larger numbers of tumor-sensitized IFN-gamma (KO) T cells or by immunosensitizing sublethal irradiation (500 rad) of the host before adoptive therapy. Extrapulmonary tumors (MCA-205 s.c. and intracranial) that required adjunct sublethal irradiation for treatment efficacy also displayed no requirement for host or T cell expression of IFN-gamma. Nonetheless, rejection of MCA-205 s.c. tumors and i.p. EL-4 tumors, but not MCA-205 pulmonary or intracranial tumors, displayed a significant requirement for T cell perforin expression (i.e., CTL participation). The capacity of T cells to lyse tumor targets and secrete IFN-gamma in vitro before adoptive transfer was nonpredictive of the roles of these activities in subsequent tumor rejection. Adoptive therapy studies employing KO mice are therefore indispensable for revealing a diversity of tumor rejection mechanisms that may lack in vitro correlation due to delays in their induction. Seemingly contradictory KO data from different studies are reconciled by the capacity of anti-tumor T cells to rely on alternative mechanisms when treated in larger numbers, the variable participation of CTL at different anatomic locations of tumor, and the apparent capacity of sublethal irradiation to provide a therapeutic alternative to host or T cell IFN-gamma production.
