Abstract
3004 Background: We have previously reported that vaccination with IDM therapeutic vaccine (IDD-3/Uvidem [Uvidem is co-developed with SANOFI-AVENTIS]) composed of dendritic cells (DC) loaded with three allogeneic lysates from tumor cell lines can elicit immune and anti-tumor responses. We describe here the preliminary results from a phase II clinical trial in metastatic melanoma patients. Methods: DC-MEL-202 is a single arm, two-stage phase II trial designed to evaluate clinical and immunological activities and the safety of a multivalent DC vaccine in patients with in-transit or low volume metastatic melanoma. There was no HLA restriction. Autologous DC were generated, under GMP conditions, from monocytes cultured in GM-CSF and IL-13, loaded with three allogeneic melanoma tumor lysates (M44, SK-MEL 28 and COLO 829) and matured with a combination of bacterial extract (FMKP) and IFN-γ, generating up to 15 doses of the vaccine containing 25x106 DC. Patients received six bi-weekly and two 6-weekly injections (id and sc). Clinical responders were eligible to receive additional doses. Immune response against tumor-associated antigens (TAA) peptides was assessed, at several time points, by detection of IFN-γ producing cells by flow cytometry Results: 33 patients were treated. To date: Vaccination is well tolerated with toxicity limited to mild events (only one possibly related SAE, age-related macular degeneration, was reported). Clinical response (RECIST): 6 patients showed evidence of clinical benefit (1CR, 1PR and 4 SD) with duration of response ranging from 7.5 to 22 months. Assessment of pathological response in target sites in 2 pts (1 PR, 1 SD) showed no residual disease.. 23/33 patients are still alive with a mean follow-up of 11mo (range 3–22mo). Mature data of PFS and OS will be presented. Immune response: 21 (84 %) out of 25 evaluated patients showed detectable TAA-specific CD8+ T cells with ten showing boosted or appearance of anti-TAA specific CD8+ T cells. Conclusions: Vaccination with IDD-3/Uvidem is safe and can elicit tumor specific CD8+ T cells not limited to HLA-A2+ patients. Substantial clinical benefit warrants further development of IDD3. No significant financial relationships to disclose.

Abstract
CD8(+) T cells are important effectors, as well as regulators, of organ-specific autoimmunity. Compared with Tc1-type CD8(+) cells, Tc2 cells have impaired anti-viral and anti-tumor effector functions, although no data are yet available on their pathogenic role in autoimmunity. Our aim was to explore the role of autoreactive Tc1 and Tc2 cells in autoimmune diabetes. We set up an adoptive transfer model in which the recipients were transgenic mice expressing influenza virus hemagglutinin (HA) specifically in their pancreatic ss islet cells (rat insulin promoter-HA mice) and islet-specific Tc1 and Tc2 cells were generated in vitro from HA-specific CD8(+) cells of TCR transgenic mice (CL4-TCR mice). One million Tc1 cells, differentiated in vitro in the presence of IL-12, transferred diabetes in 100% of nonirradiated adult rat insulin promoter-HA recipients; the 50% diabetogenic dose was 5 x 10(5). Highly polarized Tc2 cells generated in the presence of IL-4, IL-10, and anti-IFN-gamma mAb had a relatively low, but definite, diabetogenic potential. Thus, 5 x 10(6) Tc2 cells caused diabetes in 6 of 18 recipients, while the same dose of naive CD8(+) cells did not cause diabetes. Looking for the cause of the different diabetogenic potential of Tc1 and Tc2 cells, we found that Tc2 cells are at least as cytotoxic as Tc1 cells but their accumulation in the pancreas is slower, a possible consequence of differential chemokine receptor expression. The diabetogenicity of autoreactive Tc2 cells, most likely caused by their cytotoxic activity, precludes their therapeutic use as regulators of autoimmunity.

Abstract
Insulin-dependent diabetes is an autoimmune disease targeting pancreatic beta-islet cells. Recent data suggest that autoreactive CD8+ T cells are involved in both the early events leading to insulitis and the late destructive phase resulting in diabetes. Although therapeutic injection of protein and synthetic peptides corresponding to CD4+ T cell epitopes has been shown to prevent or block autoimmune disease in several models, down-regulation of an ongoing CD8+ T cell-mediated autoimmune response using this approach has not yet been reported. Using CL4-TCR single transgenic mice, in which most CD8+ T cells express a TCR specific for the influenza virus hemagglutinin HA512-520 peptide:Kd complex, we first show that i.v. injection of soluble HA512-520 peptide induces transient activation followed by apoptosis of Tc1-like CD8+ T cells. We next tested a similar tolerance induction strategy in (CL4-TCR x Ins-HA)F1 double transgenic mice that also express HA in the beta-islet cells and, as a result, spontaneously develop a juvenile onset and lethal diabetes. Soluble HA512-520 peptide treatment, at a time when pathogenic CD8+ T cells have already infiltrated the pancreas, very significantly prolongs survival of the double transgenic pups. In addition, we found that Ag administration eliminates CD8+ T cell infiltrates from the pancreas without histological evidence of bystander damage. Our data indicate that agonist peptide can down-regulate an autoimmune reaction mediated by CD8+ T cells in vivo and block disease progression. Thus, in addition to autoreactive CD4+ T cells, CD8+ T cells may constitute targets for Ag-specific therapy in autoimmune diseases.

Abstract
Although the two-signal model for T cell activation states that a signal-1 through the TCR and a costimulatory signal-2 are required for optimal stimulation, it is now clear that the requirement for costimulation can be bypassed under certain conditions. We previously reported that this is the case for naive CD8+ T cells in vitro. In the present study we tested the effect of signal-2 when delivered after signal-1 has been disrupted. Naive CD8+ T cells from TCR transgenic mice were stimulated in vitro by using immobilized recombinant single-chain MHC molecules alone as signal-1. This signal was then stopped after different lengths of time, and anti-CD28 mAb as signal-2 was given either immediately or after a time lag. We found that signal-2 can potentiate a short signal-1 when added sequentially. Moreover, a time lag between the two signals does not abolish this potentiation. If the strength of signal-1, but not its duration, is increased, then the time lag between the delivery of signals 1 and 2 can be lengthen without loss of potentiation. Together, our results indicate that the two signals do not need to be delivered concomitantly to get optimal T cell activation. We suggest that the CD8+ T cells can reach a transient "excited" state after being stimulated with signal-1 alone, characterized by the cell's ability to respond to separate and delayed signal-2.

Abstract
There is now convincing evidence that autoreactive CD8+ T cells can contribute to the pathogenesis of organ-specific autoimmune diseases. In the non-obese diabetic mouse, there is direct evidence that beta-islet cell-specific CD8+ cytotoxic T cells have a pathogenic effect. In human diseases such as autoimmune diabetes and multiple sclerosis, indirect evidence also suggests a role for CD8+ T cells in tissue damage, although their antigen specificity is unknown. Transgenic mouse models as well as the use of knockout mice have been instrumental in the identification of the role of autoreactive CD8+ T cells. Spontaneous models of CD8+ T-cell-mediated autoimmunity generated through transgenesis should help delineate the effector mechanisms leading to tissue destruction. The study of autoreactive CD8+ T cells and the characterization of their antigenic specificity should help unravel the pathophysiology of organ-specific autoimmune diseases, help identify exacerbating foreign antigens, and allow the design of antigen-specific immunotherapy targeting the pathogenic autoreactive T cells.

Antigen-specific T cell tolerance can be induced by systemic injection of high-dose antigen. In particular, a single intravenous (i.v.) injection of influenza virus hemagglutinin peptide in HNT-TCR transgenic mice induces T cell tolerance through thymocyte apoptosis as well as anergy and deletion of peripheral CD4+ T cells. We now show that this tolerance is reversed after 8 weeks probably due to the short in vivo half-life of the peptide. Since durable tolerance is required for this strategy to be of therapeutic value, we tested whether weekly i.v. injections of peptide (up to 12 weeks) could maintain the CD4+ T cell tolerance. Each injection induces a profound deletion of thymocytes, although their level recovers before the next injection. Therefore, during the treatment period, the thymus undergoes cycles of contraction/expansion. In the periphery, the number of CD4+ T cells is stably decreased and the persisting CD4+ T cells are hyporeactive both in vitro and in vivo. This tolerance is essentially peripheral since comparable results were obtained in thymectomized HNT-TCR mice injected weekly. Our data show that stable antigen-specific tolerance can be induced by repeated i.v. injections of antigen. These findings might have implications for the treatment of T cell-mediated autoimmune diseases.

Abstract
Dendritic cells (DCs) are much more potent antigen (Ag)-presenting cells than resting B cells for the activation of naive T cells. The mechanisms underlying this difference have been analyzed under conditions where ex vivo DCs or B cells presented known numbers of specific Ag-major histocompatibility complex (MHC) complexes to naive CD4(+) T cells from T cell antigen receptor (TCR) transgenic mice. Several hundred Ag-MHC complexes presented by B cells were necessary to elicit the formation of a few T-B conjugates with small contact zones, and the resulting individual T cell Ca2+ responses were all-or-none. In contrast, Ag-specific T cell Ca2+ responses can be triggered by DCs bearing an average of 30 Ag-MHC complexes per cell. Formation of T-DC conjugates is Ag-independent, but in the presence of the Ag, the surface of the contact zone increases and so does the amplitude of the T cell Ca2+ responses. These results suggest that Ag is better recognized by T cells on DCs essentially because T-DC adhesion precedes Ag recognition, whereas T-B adhesion requires Ag recognition. Surprisingly, we also recorded small Ca2+ responses in T cells interacting with unpulsed DCs. Using DCs purified from MHC class II knockout mice, we provide evidence that this signal is mostly due to MHC-TCR interactions. Such an Ag-independent, MHC-triggered calcium response could be a survival signal that DCs but not B cells are able to deliver to naive T cells.

Abstract
The two-signal model states that activation of naive T cells requires a signal 1 stimulus through the TCR and a co-stimulatory signal 2. By contrast, signal 1 alone is sufficient for pre-activated T cells. Recently, however, it has been shown that under certain conditions T cells can bypass the requirement for co-stimulation. For example, CD28-deficient mice, when immunized with lymphocytic choriomeningitis virus, mount a vigorous cytotoxic T lymphocyte response and clear the virus. As a continuous effort to unravel the mechanisms of T cell activation, we previously reported activation of hybridoma T cells by recombinant single-chain MHC molecules in the absence of antigen-presenting cells. In such reconstitution experiments, since the signals delivered to the T cells are well controlled, the contribution of any known or unknown signals can be ruled out. In the present study, we analyzed the requirements for activation of naive T cells by using splenocytes from TCR transgenic mice as a source of responding cells. We observed that naive CD8+ T cells are fully activated by signal 1 alone, but that co-stimulation lowers their activation threshold. Previously activated T cells are fully responsive, even when the first stimulation was performed in the absence of co-stimulation. They display a low activation threshold and are insensitive to co-stimulation. The physiological relevance of this finding and its consequences for immunotherapy as well as for our understanding of self-tolerance are discussed.

Abstract
Antigen recognition was analyzed at the single-cell level by using for the first time T cells which were not altered by in vitro selection, transfection or immortalization. The first consequence of antigen recognition by ex vivo naive CD4+ T cells from T cell receptor (TCR)-transgenic mice is the formation of a "contact zone" with the B cell presenting the antigen. The T cell intracellular calcium (Ca2+) response begins after a delay of 30 s on average, following the formation of the contact zone. The T cell response is entirely inhibited by either protein tyrosine kinase or actin polymerization inhibitors but, surprisingly, it is insensitive to inhibitors of phosphoinositide 3-kinase. Moreover, inhibition of microtubule polymerization and use of Ca2+-free medium do not prevent the beginning of the T cell response, but do reduce the stability of the contact zone and/or the amplitude of the Ca2+ plateau. The critical involvement of the cytoskeleton in antigen recognition on B cells introduces a checkpoint in T cell activation: the initial TCR engagement triggers a Ca2+ response only after an amplification step corresponding to a cytoskeleton-controlled increase in the number of engaged TCR.

Abstract
Systemic injection of antigen is one of the approaches that reproducibly induces effective antigen-specific hyporesponsiveness. Here, Roland Liblau and colleagues discuss the cellular and molecular bases of such tolerance, review the current use of this therapeutic strategy in experimental organ-specific autoimmune diseases and analyse what steps are necessary to make this approach suitable for clinical use.

Abstract
Numerous studies have focused on characterizing and monitoring antigen-specific T cells during the course of an immune response. Mostly indirect methods were used to circumvent the low frequency of T cell precursors and the inherent complexity of T cell receptor (TcR)-MHC-peptide interactions. Here, we took advantage of peptide-specific adhesion induced by immobilized MHC-peptide complexes. We describe a simple technique which allows enrichment in antigen-specific T lymphocytes among a heterogeneous CD8+ T cell population. Enrichment of T cells according to their specificity should facilitate their characterization and provide an attractive tool for immunotherapy.
