Abstract
Regulatory T cells (Tregs) play a key role in maintaining immune homeostasis and preventing autoimmunity through their immunosuppressive function. There have been numerous reports confirming that high levels of Tregs in the tumor microenvironment (TME) are associated with a poor prognosis, highlighting their role in promoting an immunosuppressive environment. In breast cancer (BC), Tregs interact with cancer cells, ultimately leading to the suppression of immune surveillance and promoting tumor progression. This review discusses the dual role of Tregs in breast cancer, and explores the controversies and therapeutic potential associated with targeting these cells. Researchers are investigating various strategies to deplete or inhibit Tregs, such as immune checkpoint inhibitors, cytokine antagonists, and metabolic inhibition. However, the heterogeneity of Tregs and the variable precision of treatments pose significant challenges. Understanding the functional diversity of Tregs and the latest advances in targeted therapies is critical for the development of effective therapies. This review highlights the latest approaches to Tregs for BC treatment that both attenuate Treg-mediated immunosuppression in tumors and maintain immune tolerance, and advocates precise combination therapy strategies to optimize breast cancer outcomes.

Abstract
The T cell co-stimulatory molecule OX40 and its cognate ligand OX40L have attracted broad research interest as a therapeutic target in T cell-mediated diseases. Accumulating preclinical evidence highlights the therapeutic efficacy of both agonist and blockade of the OX40-OX40L interaction. Despite this progress, many questions about the immuno-modulator roles of OX40 on T cell function remain unanswered. In this review we summarize the impact of the OX40-OX40L interaction on T cell subsets, including Th1, Th2, Th9, Th17, Th22, Treg, Tfh, and CD8+ T cells, to gain a comprehensive understanding of anti-OX40 mAb-based therapies. The potential therapeutic application of the OX40-OX40L interaction in autoimmunity diseases and cancer immunotherapy are further discussed; OX40-OX40L blockade may ameliorate autoantigen-specific T cell responses and reduce immune activity in autoimmunity diseases. We also explore the rationale of targeting OX40-OX40L interactions in cancer immunotherapy. Ligation of OX40 with targeted agonist anti-OX40 mAbs conveys activating signals to T cells. When combined with other therapeutic treatments, such as anti-PD-1 or anti-CTLA-4 blockade, cytokines, chemotherapy, or radiotherapy, the anti-tumor activity of agonist anti-OX40 treatment will be further enhanced. These data collectively suggest great potential for OX40-mediated therapies.

Abstract
The tumour necrosis factor receptor OX40 (CD134) is activated by its cognate ligand OX40L (CD134L, CD252) and functions as a T cell co-stimulatory molecule. OX40-OX40L interactions have been proposed as a potential therapeutic target for treating autoimmunity. OX40 is expressed on activated T cells, and in the mouse at rest on regulatory T cells (Treg). OX40L is found on antigen-presenting cells, activated T cells and others including lymphoid tissue inducer cells, some endothelia and mast cells. Expression of both molecules is increased after antigen presentation occurs and also in response to multiple other pro-inflammatory factors including CD28 ligation, CD40L ligation and interferon-gamma signaling. Their interactions promote T cell survival, promote an effector T cell phenotype, promote T cell memory, tend to reduce regulatory function, increase effector cytokine production and enhance cell mobility. In some circumstances, OX40 agonism may be associated with increased tolerance, although timing with respect to antigenic stimulus is important. Further, recent work has suggested that OX40L blockade may be more effective than OX40 blockade in reducing autoimmunity. This article reviews the expression of OX40 and OX40L in health, the effects of their interactions and insights from their under- or over-expression. We then review OX40 and OX40L expression in human autoimmune disease, identified associations of variations in their genes (TNFRSF4 and TNFSF4, respectively) with autoimmunity, and data from animal models of human diseases. A rationale for blocking OX40-OX40L interaction in human autoimmunity is then presented along with commentary on the one trial of OX40L blockade in human disease conducted to date. Finally, we discuss potential problems with clinical use of OX40-OX40L directed pharmacotherapy.

Abstract
The concept of using immunotherapy to treat melanoma has existed for decades. The rationale comes from the knowledge that many patients with melanoma have endogenous immune responses against their tumor cells and clinically meaningful tumor regression can be achieved in a minority of patients using cytokines such as interleukin-2 and adoptive cellular therapy. In the last 5 years there has been a revolution in the clinical management of melanoma in large measure based on the development of antibodies that influence T cell regulatory pathways by overcoming checkpoint inhibition and providing co-stimulation, either of which results in significantly more effective immune-mediated tumor destruction. This review will describe the pre-clinical and clinical application of antagonistic antibodies targeting the T-cell checkpoints cytotoxic T-lymphocyte antigen 4 (CTLA-4) and programmed death 1 (PD-1), and agonistic antibodies targeting the costimulatory pathways OX40 and 4-1BB. Recent progress and opportunities for future investigation of combination antibody therapy will be described.

Abstract
Autoimmune diseases are characterized by the body's ability to mount immune attacks on self. This results from recognition of self-proteins and leads to organ damage due to increased production of pathogenic inflammatory molecules and autoantibodies. Over the years, several new potential therapeutic targets have been identified in autoimmune diseases, notable among which are members of the tumour necrosis factor (TNF) superfamily. Here, we review the evidence that certain key members of this superfamily can augment/suppress autoimmune diseases.

Abstract
We report that OX40 stimulation drives all lineages of CD4 T cell development, including regulatory T cells (Tregs), and the plasticity of the response is dependant on local cytokines. In TGF-beta1-treated cultures, an OX40 agonist increased IFN-gamma and IL-4 production and diverted T cells from the Treg lineage. However, cytokine blockade in the context of OX40 stimulation promoted enhanced Treg accumulation. This observation was evident in naive mice, as OX40 engagement enhanced Treg proliferation and accumulation in vivo. Lastly, OX40 agonist administration influenced experimental autoimmune encephalomyelitis disease severity in opposing directions, depending on the timing of administration. Given during Ag priming, the OX40 agonist drove Treg expansion and inhibited disease, whereas given later it enhanced T cell effector cytokine production in the CNS and exacerbated disease. Hence, OX40 signaling can augment the accumulation of all CD4 T cell lineages; however, its accentuation of immune responses may have vastly different biologic outcomes depending upon the local cytokine milieu.

Abstract
The interaction between OX40 and OX40L plays an important role in antigen-specific T-cell expansion and survival. While OX40 is expressed predominantly on T-lymphocytes early after antigen activation, OX40L is expressed on activated antigen presenting cells and endothelial cells within acute inflammatory environments. We discuss here how ligation of OX40 by OX40L leads to enhanced T-cell survival, along with local inflammatory responses that appear critical for both effective T-cell mediated responses and chronic immune pathologies. We describe how interventions that block or mimic the OX40-OX40L interaction can be applied to treat autoimmune diseases or enhance anti-tumor immune responses. The clinically relevant properties of these agents emphasize the importance of this particular TNFSF-TNFSF in health and disease.

Abstract
Costimulatory signals regulate T-cell activation. To investigate the role of costimulation in autoimmunity and transplantation, we studied the BB rat model of type 1 diabetes. Diabetes-prone BB (BBDP) rats spontaneously develop disease when 55-120 days of age. We observed that two anti-CD28 monoclonal antibodies (mAb) with different functional activities completely prevented diabetes in BBDP rats. Anti-CD154 mAb delayed diabetes, whereas treatment with CTLA4-Ig or anti-CD80 mAb accelerated disease. Anti-CD86 or anti-CD134L mAbs had no effect. Diabetes resistant BB (BBDR) rats are disease-free, but >95% of them develop diabetes after treatment with polyinosinic-polycytidylic acid and an mAb that depletes Treg cells. In the induced BBDR model, anti-CD154 mAb delayed onset of diabetes, whereas CTLA4-Ig, anti-CD134L or either of the anti-CD28 mAbs had little or no effect. In contrast, blockade of the CD134-CD134L pathway was highly effective for preventing autoimmune recurrence against syngeneic islet grafts in diabetic BBDR hosts. Blockade of the CD40-CD154 pathway was also effective, but less so. These data suggest that the effectiveness of costimulation blockade in the treatment of type 1 diabetes is dependent on both the costimulatory pathway targeted and the mechanism of induction, stage, intensity and duration of the pathogenic process.

Abstract
Several members of the tumor necrosis factor receptor (TNFR) family function after initial T cell activation to sustain T cell responses. This review focuses on CD27, 4-1BB (CD137), OX40 (CD134), HVEM, CD30, and GITR, all of which can have costimulatory effects on T cells. The effects of these costimulatory TNFR family members can often be functionally, temporally, or spatially segregated from those of CD28 and from each other. The sequential and transient regulation of T cell activation/survival signals by different costimulators may function to allow longevity of the response while maintaining tight control of T cell survival. Depending on the disease condition, stimulation via costimulatory TNF family members can exacerbate or ameliorate disease. Despite these complexities, stimulation or blockade of TNFR family costimulators shows promise for several therapeutic applications, including cancer, infectious disease, transplantation, and autoimmunity.

Abstract
T cells have an important role during the development of autoimmune diseases. In adjuvant arthritis, a model for rheumatoid arthritis, we found that the percentage of CD4+ T cells expressing the activation marker CD134 (OX40 antigen) was elevated before disease onset. Moreover, these CD134+ T cells showed a specific proliferative response to the disease-associated epitope of mycobacterial heat shock protein 60, indicating that this subset contains auto-aggressive T cells. We studied the usefulness of CD134 as a molecular target for immune intervention in arthritis by using liposomes coated with a CD134-directed monoclonal antibody as a drug targeting system. Injection of anti-CD134 liposomes subcutaneously in the hind paws of pre-arthritic rats resulted in targeting of the majority of CD4+CD134+ T cells in the popliteal lymph nodes. Furthermore, we showed that anti-CD134 liposomes bound to activated T cells were not internalized. However, drug delivery by these liposomes could be established by loading anti-CD134 liposomes with the dipalmitate-derivatized cytostatic agent 5'-fluorodeoxyuridine. These liposomes specifically inhibited the proliferation of activated CD134+ T cells in vitro, and treatment with anti-CD134 liposomes containing 5'-fluorodeoxyuridine resulted in the amelioration of adjuvant arthritis. Thus, CD134 can be used as a marker for auto-aggressive CD4+ T cells early in arthritis, and specific liposomal targeting of drugs to these cells via CD134 can be employed to downregulate disease development.

Abstract
BACKGROUND CD134 (OX40) is a member of the tumor necrosis factor receptor superfamily that is expressed as a late event in T-cell activation and contributes to the generation of immunologic memory. CD134 blockade effectively ameliorates inflammation in models of autoimmune disease, but its role in transplantation has been less well studied. METHODS The authors used an OX40-immunoglobulin (Ig) fusion protein to examine the contribution of this co-stimulatory molecule to the in vitro alloimmune response and studied the ability of CD134 blockade to prevent cardiac allograft rejection in mouse models of heart transplantation using strains representing both major histocompatibility complex (MHC) (BALB/c to CBA/Ca) and minor histocompatibility complex (mHC) (B10.BR to CBA/Ca) antigen mismatches. RESULTS CD134 upregulation on in vitro alloactivated T cells was delayed compared with CD69 and CD25, and inhibition of T-cell proliferation was critically dependent on the timing of OX40-Ig administration. Heart allograft survival in a fully allogeneic, MHC-mismatched strain combination was not influenced by CD134 blockade alone, but OX40-Ig treatment in the mHC-mismatched model resulted in long-term graft survival (median survival time extended from 14 days to >100 days). Early mononuclear cell infiltration of the graft was similar in both rejecting and long-surviving heart grafts, but OX40-Ig treatment appeared to delay cellular infiltration. CONCLUSIONS These results show that CD134-CD134L interaction plays an important role in the co-stimulatory cascade and that blockade of this molecular interaction may be of therapeutic value in helping to prevent allograft rejection.

Abstract
To take advantage of the growing knowledge of cellular signaling pathways, modern-day drug discovery faces an increasing challenge to develop assays to screen for compounds that modulate protein-protein interactions. One bottleneck in achieving this goal is a lack of suitable and robust assay technologies amenable to a high-throughput format. In this report, we describe how we utilized Alphascreen trade mark technology to develop a high-throughput assay to monitor ligand binding to a member of the tumor necrosis factor receptor superfamily. We expressed a fusion protein consisting of the extracellular domain of the OX40 receptor with the constant domains of human IgG. In the presence of OX40 ligand, we determined a binding affinity constant consistent with reported values and optimized the protocol to develop a simple, homogeneous, and sensitive binding assay in a 384-well format. Finally, we assessed if this system could identify small peptides capable of inhibiting the OX40 receptor and ligand interaction. The results showed that the assay was able to detect such peptides and could be used to launch a high-throughput screening campaign for small molecules able to prevent OX40 receptor activation.

Abstract
Interaction of OX40 (CD134) on T cells with its ligand (OX40L) on antigen-presenting cells has been implicated in pathogenic T cell activation. This study was performed to explore the involvement of OX40/OX40L in the development of T cell-mediated chronic colitis. We evaluated both the preventive and therapeutic effects of neutralizing anti-OX40L MAb on the development of chronic colitis in SCID mice induced by adoptive transfer of CD4(+)CD45RB(high) T cells as an animal model of Crohn's disease. We also assessed the combination of anti-OX40L and anti-TNF-alpha MAbs to improve the therapeutic effect. Administration of anti-OX40L MAb markedly ameliorated the clinical and histopathological disease in preventive and therapeutic protocols. In vivo treatment with anti-OX40L MAb decreased CD4(+) T cell infiltration in the colon and suppressed IFN-gamma, IL-2, and TNF-alpha production by lamina propria CD4(+) T cells. The combination with anti-TNF-alpha MAb further improved the therapeutic effect by abolishing IFN-gamma, IL-2, and TNF-alpha production by lamina propria CD4(+) T cells. Our present results suggested a pivotal role of OX40/OX40L in the pathogenesis of T cell-mediated chronic colitis. The OX40L blockade, especially in combination with the TNF-alpha blockade, may be a promising strategy for therapeutic intervention of Crohn's disease.

Abstract
The CD134-CD134 ligand (CD134L) costimulatory pathway has been shown to be critical for both T and B cell activation; however, its role in regulating the alloimmune response remains unexplored. Furthermore, its interactions with other costimulatory pathways and immunosuppressive agents are unclear. We investigated the effect of CD134-CD134L pathway blockade on allograft rejection in fully MHC-mismatched rat cardiac and skin transplantation models. CD134L blockade alone did not prolong graft survival compared with that of untreated recipients, and in combination with donor-specific transfusion, cyclosporine, or rapamycin, was less effective than B7 blockade in prolonging allograft survival. However, in combination with B7 blockade, long-term allograft survival was achieved in all recipients (>200 days). Moreover, this was synergistic in reducing the frequency of IFN-gamma-producing alloreactive lymphocytes and inhibiting the generation of activated/effector lymphocytes. Most impressively, this combination prevented rejection in a presensitized model using adoptive transfer of primed lymphocytes into athymic heart transplant recipients. In comparison to untreated recipients (mean survival time (MST): 5.3 +/- 0.5 days), anti-CD134L mAb alone modestly prolonged allograft survival (MST: 14 +/- 2.8 days) as did CTLA4Ig (MST: 21.5 +/- 1.7 days), but all grafts were rejected within 24 days. Importantly, combined blockade further and significantly prolonged allograft survival (MST: 75.3 +/- 12.7 days) and prevented the expansion and/or persistence of primed/effector alloreactive T cells. Our data suggest that CD134-CD134L is a critical pathway in alloimmune responses, especially recall/primed responses, and is synergistic with CD28-B7 in mediating T cell effector responses during allograft rejection. Understanding the mechanisms of collaboration between these different pathways is important for the development of novel strategies to promote long-term allograft survival.

Abstract
OX40 (CD134), a membrane-bound member of the tumor-necrosis-factor-receptor superfamily, is expressed primarily on activated CD4+ T cells. Recently, several groups have reduced clinical signs of autoimmunity in animal models by blocking the OX40-OX40-ligand interaction or depleting OX40+ T cells. By contrast, engagement of OX40 in the setting of active immunization has potent adjuvant properties, leading to enhanced cytokine production and increased numbers of antigen-specific memory T cells. These potent adjuvant effects lead to an enhancement of anti-tumor responses. OX40 has several unique features that make it a clinically relevant target. They include: (1) T cells isolated from a site of inflammation that express OX40 are T cells that have been stimulated recentlythrough the T-cell receptor in vivo; (2) OX40 is only expressed on T cells found at the site of inflammation, therefore, targeting this receptor does not interfere with the peripheral T-cell repertoire; and (3) the biological function of OX40 is limited primarily to effector CD4+ T cells, which are a major source of cytokines to induce and maintain ongoing immune responses.

Abstract
Increasing the long-term survival of memory T cells after immunization is key to a successful vaccine. In the past, the generation of large numbers of memory T cells in vivo has been difficult because Ag-stimulated T cells are susceptible to activation-induced cell death. Previously, we reported that OX40 engagement resulted in a 60-fold increase in the number of Ag-specific CD4(+) memory T cells that persisted 60 days postimmunization. In this report, we used the D011.10 adoptive transfer model to examine the kinetics of Ag-specific T cell entry into the peripheral blood, the optimal route of administration of Ag and alphaOX40, and the Ag-specific Ab response after immunization with soluble OVA and alphaOX40. Finally, we compared the adjuvant properties of alphaOX40 to those of alphaCTLA-4. Engagement of OX-40 in vivo was most effective when the Ag was administered s.c. Time course studies revealed that it was crucial for alphaOX40 to be delivered within 24-48 h after Ag exposure. Examination of anti-OVA Ab titers revealed a 10-fold increase in mice that received alphaOX40 compared with mice that received OVA alone. Both alphaOX40 and alphaCTLA-4 increased the percentage of OVA-specific CD4(+) T cells early after immunization (day 4), but alphaOX40-treated mice had much higher percentages of OVA-specific memory CD4(+) T cells from days 11 to 29. These studies demonstrate that OX40 engagement early after immunization with soluble Ag enhances long-term T cell and humoral immunity in a manner distinct from that provided by blocking CTLA-4.

Abstract
OX40 (CD134) and its ligand (OX40L) have been implicated in T cell activation and migration. In this study, we examined the contribution of these molecules to the pathogenesis of experimental autoimmune encephalomyelitis (EAE) by administering a neutralizing mAb against murine OX40L (RM134L) to proteolipid protein (139-151) peptide-induced EAE in SJL mice. Administration of RM134L effectively ameliorated the disease in both actively induced and adoptively transferred EAE models. Histological examination showed that the RM134L treatment greatly reduced mononuclear cell infiltration into the spinal cord. The RM134L treatment did not inhibit the development of pathogenic T cells, given that proliferative response and IFN-gamma production by draining lymph node cells were not reduced or rather enhanced upon restimulation with proteolipid protein (139-151) in vitro, and these cells effectively transferred EAE to naive SJL mice. Flow cytometric analyses showed that the RM134L treatment inhibited the accumulation of OX40-expressing CD4(+) T cells and the migration of adoptively transferred CD4(+) T cells in the spinal cord. Immunohistochemical staining showed that OX40L was most prominently expressed on endothelial cells in the inflamed spinal cord. These results suggest that the OX40/OX40L interaction plays a critical role for the migration of pathogenic T cells into the CNS in the pathogenesis of EAE.

Abstract
OBJECTIVE Oral administration of antigen prior to disease induction has been shown to induce peripheral tolerance in several experimental autoimmune diseases. However, the clinical benefit of pretreatment with antigens is limited. The aim of this study was to investigate whether adjuvant-induced arthritis (AIA) could be treated by oral administration of mycobacterial heat-shock protein 65 (Hsp65) during ongoing disease. METHODS AIA was induced in Lewis rats by immunization with Mycobacterium tuberculosis in Freund's incomplete adjuvant. Oral feeding of Hsp65 in the presence or absence of soybean trypsin inhibitor (SBTI) was started on day 11 after immunization. Arthritis was monitored visually, and joint pathology was examined radiologically. RESULTS Oral treatment with Hsp65 during ongoing disease significantly reduced the activity of AIA. However, treatment with Hsp65 was only successful when SBTI was coadministered to prevent breakdown of the Hsp65. The beneficial effect of Hsp65/SBTI treatment during AIA was also represented by a clear reduction of articular destruction, as visualized by radiography. Moreover, feeding Hsp65/SBTI resulted in a lower number of both spleen and mesenteric lymph node (MLN) cells expressing the costimulatory molecule CD80 (B7-1). The number of cells expressing CD86 (B7-2) was not altered. Furthermore, MLN cells from AIA animals treated with Hsp65/SBTI contained a lower number of T cells expressing the activation marker CD134 (Ox-40). In addition, treatment with Hsp65/ SBTI was accompanied by an increased proliferative response of spleen cells to the Hsp65 antigen in vitro. Moreover, Hsp65/SBTI-treated rats showed less Hsp65-specific interferon-gamma and increased production of interleukin-10. CONCLUSION Ongoing AIA activity can be reduced by oral administration of Hsp65 only when protein breakdown in the gastrointestinal tract is inhibited.

Abstract
OBJECTIVES The OX-40 receptor (OX-40R/CD134) is expressed primarily on activated CD4(+) ("helper") T cells. We have previously reported the presence of OX-40(+) T cells in head and neck cancer and melanoma, where they appear to be restricted to tumor compartments (primary tumor infiltrating lymphocytes [TILs] and draining lymph node cells) and therefore may represent the tumor antigen-specific CD4(+) T cells. METHODS In order to determine the degree of OX-40R expression, and any relationship with the presence of tumor cells (lobular and/or infiltrating ductal carcinoma), 45 archived paraffin-embedded breast primary tumors and their associated draining (axillary) lymph nodes were retrospectively analyzed using standard immunohistochemical techniques. RESULTS Seven of 45 primary tumors (16%) and 7 of 29 with lympocytic infiltrates (24%) were noted to have elevated levels of OX-40R(+) lymphocytes within the tumor specimens, including 2 of 4 specimens thought to have only "pure" ductal carcinoma in situ (DCIS). No OX-40R(+) lymphocytes were noted in normal breast tissue. Twenty-one (43%) patients had axillary metastases at the time of resection. High levels of OX-40R expression was seen in 9 (45%) of these 21 axillary node specimens, whereas no such staining was seen in the node-negative specimens (P <0.001). Furthermore, in a patient thought to be without axillary disease, several subcapsular single-cell metastases were retrospectively discovered near a lone cluster of OX-40R(+) lymphocytes. In general, visual inspection showed OX-40R(+) T cells to be in close proximity to tumor and often in direct contact with metastatic cells. CONCLUSIONS The OX-40R is upregulated on lymphocytes within tumor draining lymph nodes, and these lymphocytes are specifically localized around tumor deposits. These data imply that OX-40R immunostaining may be useful for both determination of occult involvement of lymph nodes by tumor and for identification of potential candidates for future OX-40 based immunotherapy.

Abstract
Abstract
CD134 (OX40) is a member of the TNF receptor family that is expressed on activated T lymphocytes. T cells from mice that lack expression of CD134 made strong responses to a range of challenges, but they showed impaired proliferation in response to direct stimulation through the TCR with monoclonal anti-CD3ε Ab. CD134-deficient mice controlled infection with Leishmania major, Nippostrongylus brasiliensis, and Theiler’s murine encephalomyelitis virus, and they made overtly normal Ab responses to a variety of antigens. Thus, CD134 is not essential for many T cell responses in vivo, nor is it required for the provision of help to B cells. Nonetheless, a subtle role in the regulation of T cell reactivity is suggested by the effect of CD134 deficiency on in vitro T cell responses.

Abstract
Abstract
The OX-40R is a member of the TNF receptor family and is expressed primarily on activated CD4+ T cells. When the OX-40R is engaged by the OX-40 ligand (OX-40L), a potent costimulatory signal occurs. We have identified a population of CD11b+ cells, isolated from the central nervous system (CNS) of mice with actively induced experimental allergic encephalomyelitis (EAE), that expresses OX-40L. Moreover, the expression of OX-40L was found to be associated with paralytic episodes of EAE and was reduced or absent at disease recovery. These CD11b+ cells also coexpressed B7 and MHC class II. Therefore, to address the relative contributions of OX-40R/OX-40L and CD28/B7 to the costimulation of myelin-specific T cells, blocking studies were performed using soluble OX-40R and/or soluble CTLA-4. CD11b+ cells isolated from the CNS of mice with actively induced EAE were able to present Ag to proteolipid protein 139–151-specific T cell lines in vitro. The addition of soluble OX-40R:Ig to CD11b+ brain microglia/macrophages inhibited T cell proliferation by 50–70%. The addition of CTLA-4:Ig inhibited T cell proliferation by 20–30%, and the combination inhibited T cell proliferation by 95%. In vivo administration of soluble OX-40R at the onset of actively induced or adoptively transferred EAE reduced ongoing signs of disease, and the mice recovered more quickly from acute disease. The data imply that OX-40L, expressed by CNS-derived APC, acts to provide an important costimulatory signal to EAE effector T cells found within the inflammatory lesions. Furthermore, the data suggest that agents designed to inhibit the OX-40L/OX-40R complex may be useful for treating autoimmune disease.

Abstract
Abstract
Ox-40 and Ox-40 ligand (Ox-40L) are thought to be involved in T cell-APC interactions. However, their exact role in T cell responses is undefined. Using fibroblast transfectants expressing Ox-40L and/or B7-1, and CD4 cells from TCR transgenic mice, we investigated the effect of Ox-40 signaling on primary responses to the Ag pigeon cytochrome c. Ox-40 expression on naive CD4 cells peaked 2 to 3 days after activation, and was lost by 4 to 5 days. APCs with Ox-40L promoted partial activation of naive T cells with some IL-2 secretion, but were unable to enhance proliferation, unlike those with B7-1. APCs coexpressing Ox-40L with B7-1 induced large quantities of IL-2 and promoted proliferative responses that persisted for several days. Effector cells taken 5 days after naive T cell activation reexpressed Ox-40 within 4 h and responded strongly to APCs expressing Ox-40L, whereas B7-1 had little effect. Synergy was also seen between Ox-40L and B7-1, with primarily IL-2 being elevated, although IL-4 and IL-5 were also up-regulated. The most striking action was on effector T cell proliferation, which continued at high levels for up to 4 days, with little proliferation evident at this time in the absence of Ox-40 signals. These data suggest that Ox-40/Ox-40L interactions act after initial activation events to prolong clonal expansion and enhance effector cytokine secretion, and may be involved in promoting long-lived primary CD4 responses.

Abstract
Females have an increased incidence of multiple sclerosis (2:1). This gender dimorphism can be studied effectively using a murine model of relapsing experimental autoimmune encephalomyelitis (R-EAE). We demonstrated previously that male SJL mice immunized with proteolipid protein (PLP) peptide 139-151 developed an initial episode of paralysis, but failed to relapse. In the present study, clinical EAE relapses were induced by orchidectomy. Relapses in castrated mice were accompanied by an influx of activated CD4+, Th1 cells into the CNS which were absent in sham mice. Our data suggests an important regulatory role for androgens on the immune response to PLP 139-151 and the clinical course of R-EAE.

Abstract
Autoantigen-specific CD4+ T cells have been implicated as the causative cell type in: multiple sclerosis, rheumatoid arthritis, autoimmune uveitis, diabetes mellitus, inflammatory bowel disease and graft-versus-host disease. The pathology of a number of experimentally induced autoimmune diseases is also mediated by autoantigen-specific CD4+ T cells. Ideally, treatment of CD4+ T-cell-mediated diseases would eliminate the autoantigen-specific cells, while sparing the remainder of the T-cell repertoire. We have developed an effective therapy that deletes the autoreactive T cells at the site of autoimmune tissue destruction. This approach uses an antibody directed against a cell-surface protein (OX-40, also known as CD134) that is selectively upregulated on activated autoantigen-specific T cells within the inflamed tissue.

Abstract
Members of the tumor necrosis factor (TNF)-nerve growth factor (NGF) receptor family have been shown to be important costimulatory molecules for cellular activation. 4-1BB and Ox40 are two recently described members of this protein family which are expressed primarily on activated T cells. To gain insight into the signaling pathways employed by these factors, yeast two-hybrid library screens were performed with the cytoplasmic domains of 4-1BB and Ox40 as baits. TNF receptor-associated factor 2 (TRAF2) was identified as an interacting protein in both screens. The ability of both 4-1BB and Ox40 to interact with TRAF2 was confirmed in mammalian cells by coimmunoprecipitation studies. When the binding of the receptors to other TRAF proteins was investigated, 4-1BB and Ox40 displayed distinct binding patterns. While 4-1BB bound TRAF2 and TRAF1, Ox40 interacted with TRAF3 and TRAF2. Using deletion and alanine scanning analysis, we defined the elements in the cytoplasmic domains of both receptors that mediate these interactions. The 4-1BB receptor was found to have two independent stretches of acidic residues that can mediate association of the TRAF molecules. In contrast, a single TRAF binding domain was identified in the cytoplasmic tail of Ox40. The cytoplasmic domains of both receptors were shown to activate nuclear factor kappaB in a TRAF-dependent manner. Taken together, our results indicate that 4-1BB and Ox40 bind TRAF proteins to initiate a signaling cascade leading to activation of nuclear factor kappaB.

Abstract
BACKGROUND The OX-40 antigen is a cell surface glycoprotein in the tumor necrosis factor receptor family that is expressed primarily on activated CD4+ T cells. Selective target organ expression of the OX-40 receptor on autoantigen specific T cells has been found in autoimmune disease. In order to evaluate whether OX-40 is expressed on T cells from patients with nodal-draining carcinomas, OX-40 expression was assessed in tumor infiltrating lymphocytes (TILs), draining lymph node cells (DLNCs), and/or peripheral blood lymphocytes (PBLs) of 13 patients with head and neck squamous cell carcinomas and 9 patients with melanomas. METHODS Cell phenotype was determined by fluorescence cell analysis using a monoclonal antibody to human OX-40, and CD4+ T cell lymphokine production was determined by reverse transcriptase-polymerase chain reaction (RT-PCR). RESULTS Expression of the OX-40 receptor was found in as many as 31% of the TILs and as many as 28% of the DLNCs tested. Conversely, no OX-40 expression was found in PBLs. In addition, CD4+ T cells isolated from DLNCs (but not from TILs or PBLs) secreted a Th1 pattern of cytokines (IL-2, gamma interferon). Co-culture of autologous CD4+ TILs with an MHC class II+ melanoma cell line transfected with OX-40 ligand cDNA resulted in T cell proliferation and in vitro tumor regression. CONCLUSIONS These findings suggest that OX-40+ CD4+ T cells isolated from tumors and their adjacent draining nodes may represent a tumor-specific population of activated T cells capable of mediating tumor reactivity. These cells may play an exploitable role in future trials of immunotherapy.

Abstract
Abstract
The OX-40 molecule is expressed on the surface of recently activated T lymphocytes. The presence of OX-40 on CD4+ T cells was analyzed in a rat haplo-identical (parental → F1) bone marrow transplant model of acute graft-versus-host disease (aGVHD). Increased numbers of activated CD4+ T cells that expressed the OX-40 antigen were detected in peripheral blood soon after transplantation before the earliest sign of disease. The peak of OX-40 expression occurred 12 days posttransplantation with a range of 18% to 36% of circulating T cells and remained 10-fold above background, never returning to baseline. A slight increase in OX-40 expression (range, 1% to 6%) was also detected on peripheral blood lymphocytes from control syngeneic F1 → F1 recipients. OX-40+ T cells were isolated from spleen, skin, lymph node, and liver tissue of rats undergoing aGVHD, but not in syngeneic transplants. OX-40+ T cells isolated from these tissues were of donor origin and were shown to be allo-reactive. These data raise the possibility of using the OX-40 antibody to detect and deplete selectively the T cells that cause aGVHD.

Abstract
Spinal cord (SC) T cells were isolated at the onset of actively induced experimental autoimmune encephalomyelitis (EAE) and sorted for the presence of the OX-40 activation marker. Previously, we reported an enhanced bias in V beta 8.2 expression as well as enhanced proliferative responses to basic protein antigens among the OX-40+ SC T cells. Here we demonstrate that CDR3 motifs associated with EAE are present at a significantly higher frequency in V beta 8.2 sequences of OX-40+ SC T cells (16/17) compared with those of OX-40- SC T cells (5/17). Thus, the OX-40 antigen may be useful as a marker to isolate and characterize autoantigen-specific T cells from the site of inflammation in T-cell-mediated autoimmune diseases.
