Li X, Pak HS, Huber F, Michaux J, Taillandier-Coindard M, Altimiras ER, Bassani-Sternberg M. A microfluidics-enabled automated workflow of sample preparation for MS-based immunopeptidomics. CELL REPORTS METHODS 2023; 3:100479. [PMID: 37426762 PMCID: PMC10326370 DOI: 10.1016/j.crmeth.2023.100479] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 03/22/2023] [Accepted: 04/19/2023] [Indexed: 07/11/2023]
Abstract
Mass spectrometry (MS)-based immunopeptidomics is an attractive antigen discovery method with growing clinical implications. However, the current experimental approach to extract HLA-restricted peptides requires a bulky sample source, which remains a challenge for obtaining clinical specimens. We present an innovative workflow that requires a low sample volume, which streamlines the immunoaffinity purification (IP) and C18 peptide cleanup on a single microfluidics platform with automated liquid handling and minimal sample transfers, resulting in higher assay sensitivity. We also demonstrate how the state-of-the-art data-independent acquisition (DIA) method further enhances the depth of tandem MS spectra-based peptide sequencing. Consequently, over 4,000 and 5,000 HLA-I-restricted peptides were identified from as few as 0.2 million RA957 cells and a melanoma tissue of merely 5 mg, respectively. We also identified multiple immunogenic tumor-associated antigens and hundreds of peptides derived from non-canonical protein sources. This workflow represents a powerful tool for identifying the immunopeptidome of sparse samples.

Abstract
For decades, vaccines have played a significant role in protecting public and personal health against infectious diseases and proved their great potential in battling cancers as well. This review focused on the current progress of therapeutic subunit vaccines for cancer immunotherapy. Antigens and adjuvants are key components of vaccine formulations. We summarized several classes of tumor antigens and bioinformatic approaches of identification of tumor neoantigens. Pattern recognition receptor (PRR)-targeting adjuvants and their targeted delivery platforms have been extensively discussed. In addition, we emphasized the interplay between multiple adjuvants and their combined delivery for cancer immunotherapy.

Abstract
Background The influence of HLA class I and II loci on the susceptibility to melanoma remains an area of intense debate. This study aimed to examine whether the HLA system was related to melanoma susceptibility and prognosis in a southern Spanish population. Methods In this study, HLA class I and class II genotyping were performed using polymerase chain reaction sequence-specific oligonucleotides (PCR-SSO) in 237 Spanish melanoma patients and 636 ethnically matched controls. Data were analyzed according to the clinical characteristics of the defined subgroups. Results Compared to the control group, DRB1∗16:01 (4% vs. 1.3%, p=0.001, Pc = 0.035, OR = 3.28) and DQB1∗05:02 (4.9% vs. 2%, p=0.001, Pc = 0.017, OR = 2.54) were positivity associated with the susceptibility to melanoma. Both DRB1∗16:01 (5.4% vs. 1.3%, p=0.001, Pc = 0.035, OR = 4.46) and DQB1∗05:02 (6.5% vs. 2%, p=0.001, Pc = 0.017, OR = 3.44) also showed a positive correlation with Breslow thickness >1.5 mm, most notably at an early age of diagnosis (≤58 years), DRB1∗16:01 (4.2% vs. 1.3%, p=0.001, Pc = 0.035, OR = 3.41) and DQB1∗05:02 (5.4% vs. 2%, p=0.002, Pc = 0.034, OR = 2.86). Conclusion These findings established HLA-DRB1∗16:01 and HLA-DQB1∗05:02 loci as melanoma risk factors in the southern Spanish population.

Abstract
Identification of ectopic gene activation in cancer cells serves as a basis for both gene signature-guided tumor targeting and unearthing of oncogenic mechanisms to expand the understanding of tumor biology/oncogenic process. Proteins expressed only in germ cells of testis and/or placenta (immunoprivileged organs) and in malignancies are called cancer testis antigens; they are antigenic because of the lack of antigen presentation by those specific cell types (germ cells), which limits the exposure of the proteins to the immune cells. Since the Cancer Testis Antigens (CTAs) are immunogenic and expressed in a wide variety of cancer types, CT antigens have become interesting target for immunotherapy against cancer. Among CT antigens MAGEA family is reported to have 12 members (MAGEA1 to MAGEA12). The current review highlights the studies on MAGEA3 which is a CT antigen and reported in almost all types of cancer. MAGEA3 is well tried for cancer immunotherapy. Recent advances on its functional and immunological aspect warranted much deliberation on effective therapeutic approach, thus making it a more interesting target for cancer therapy.

Abstract
BACKGROUND Cancer-germline genes are a class of genes that are normally expressed in testis, trophoblast and few somatic tissues but abnormally expressed in tumor tissues. Their expression signature indicates that they can induce cellular immune responses, thus being applied as targets in cancer immunotherapy. OBJECTIVES To obtain the data of cellular immune responses against cancer-germline genes in cancer. METHODS We searched PubMed/Medline with the key words cancer-germline antigen, cancer-testis antigen, CD4+ T cell, CD8+ T cell and cancer. RESULTS About 40 cancer-germline genes have been shown to induce T cell specific responses in cancer patients. Melanoma, lung and breast cancer are among the mostly assessed cancer types. Several epitopes have been identified which can be used in immunotherapy of cancer. CONCLUSION Cellular immune responses against cancer-germline genes are indicative of appropriateness of these genes as therapeutic targets.

Abstract
Vaccination of melanoma patients with tumor-specific antigens recognized by cytotoxic T lymphocytes (CTLs) may produce significant tumor regressions. Here, we suggest a novel type of tumor vaccines, with well-studied CTL epitopes presented on highly immunogenic virus-like particle (VLP) carriers. Cancer-germline gene MAGE-3 encodes for an antigenic nonapeptide (MAGE-3(168-176) peptide) that is recognized by CTLs on human leukocyte antigen (HLA)-A1 and HLA-B35 molecules. A set of recombinant genes encoding hepatitis B virus core protein carrying MAGE-3 epitope was constructed and expressed in Escherichia coli cells. Variants that led to formation of chimeric VLPs in vivo were purified and analyzed for their DNA binding properties in vitro. VLPs exhibiting the most pronounced nucleic acid binding affinity were selected and loaded either with single-stranded DNA oligodeoxynucleotides rich in nonmethylated CG motifs, or with longer double-stranded DNA fragments. Packaged DNA was protected, at least partially, against the action of bacterial DNase. Such highly purified chimeric VLPs with entrapped immunomodulatory sequences could possibly be used as antitumor vaccines.

Abstract
BACKGROUND Clinical investigation of cancer immunotherapy has been very active and several approaches have been evaluated in Phase III trials. In particular, the characterisation at the molecular level of tumour-specific antigens, together with expert knowledge from GSK Biologicals in recombinant protein manufacturing and immunological Adjuvant Systems, has led the company to develop Antigen-Specific Cancer Immunotherapeutic (ASCI). OBJECTIVE/METHODS This paper reviews the different cancer immunotherapy approaches that have reached Phase III clinical development. A special attention is given to GSK's ASCI approach. CONCLUSION Based on encouraging data in a double-blind Phase II trial in non-small-cell lung cancer, the selection of the most suitable adjuvant system in melanoma and the choice of the adequate clinical setting for the clinical development of cancer immunotherapy, the ASCI approach offers the perspective that the long quest towards a new cancer treatment approach is about to succeed.

Abstract
Tumor regressions have been observed in a small proportion of melanoma patients vaccinated with a MAGE-A3 peptide presented by HLA-A1, administered as peptide, ALVAC canarypox virus containing a MAGE-A3 minigene, or peptide-pulsed dendritic cells (DC). There was a correlation between tumor regression and the detection of anti-MAGE-3.A1 CTL responses. These responses were monoclonal and often of a very low magnitude after vaccination with peptide or ALVAC, and usually polyclonal and of a higher magnitude after DC vaccination. These results suggested that, at least in some patients, surprisingly few anti-MAGE-3.A1 T-cells could initiate a tumor regression process. To understand the role of these T cells, we carried out a functional analysis of anti-MAGE-3.A1 CTL clones derived from vaccinated patients who displayed tumor regression. The functional avidities of these CTL clones, evaluated in lysis assays, were surprisingly low, suggesting that high avidity was not part of the putative capability of these CTL to trigger tumor rejection. Most anti-MAGE-3.A1 CTL clones obtained after DC vaccination, but not after peptide or ALVAC vaccination, produced interleukin 10. Transcript profiling confirmed these results and indicated that approximately 20 genes, including CD40L, prostaglandin D2 synthase, granzyme K, and granzyme H, were highly differentially expressed between the anti-MAGE-3.A1 CTL clones derived from patients vaccinated with either peptide-ALVAC or peptide-pulsed DC. These results indicate that the modality of vaccination with a tumor-specific antigen influences the differentiation pathway of the antivaccine CD8 T-cells, which may have an effect on their capacity to trigger a tumor rejection response.

Characterization of a single peptide derived from cytochrome P450 1B1 that elicits spontaneous human leukocyte antigen (HLA)-A1 as well as HLA-B35 restricted CD8 T-cell responses in cancer patients. Hum Immunol 2008; 69:266-72.

Abstract
Cytochrome P450 1B1 (CYP1B1) is widely expressed in human malignancies, but silent in most normal tissues. Importantly, the protein is believed to play an important role in the survival and growth of cancer cells in a stressed environment, e.g., as a result of hypoxia or chemotherapy. Thus, targeting of CYP1B1 represents a potentially successful strategy in the treatment of metastatic cancer, e.g., by therapeutic vaccination. Herein, we describe the characterization of a novel peptide from the CYP1B1 protein (CYP240), which is spontaneously recognized by CD8 T cells in cancer patients. Interestingly, the peptide binds to both human leukocyte antigen (HLA)-A1 and HLA-B35. Hence, peripheral blood lymphocytes from a total of 49 cancer patients (25 melanoma, 13 RCC, and 11 breast cancer; 41 HLA-A1 positive, 8 HLA-B35 positive) were analyzed for reactivity taking advantage of the EliSpot assay. Rare but strong responses were detected in HLA-A1-positive patients, and more frequent responses were detected in HLA-B35-positive patients. No reactivity against the peptide could be detected in healthy donors. Furthermore, we demonstrated that peptide-specific T cells were able to lyze target cells presenting the peptide on the surface. The characterized CYP240 peptide presented herein opens the avenue for more broader recruitment of patients in vaccination trials targeting CYB1B1.

Abstract
From the first evidence that the immune system could recognize tumors, different types of tumor antigens have been identified and deeply characterized. Several different approaches aimed at targeting these antigens have already been the subject of clinical studies. In this field, the GSK Biologicals' approach relying on recombinant proteins combined with an immunological Adjuvant System in a specific clinical setting, has entertained hopes of developing a new class of well tolerated anti-cancer therapy. This methodology led to promising advances with MAGE-A3 immunotherapy in NSCLC and has the potential to be applied to all tumor types.

Abstract
A 56-year patient was diagnosed adenocarcinoma of the right lung and underwent lower lobectomy. Pleural dissemination was observed, and the pathological stage was T4N0M0. Systemic chemotherapy was performed with paclitaxel and vinorelbine after the surgery. Because multiple pulmonary and liver metastases were appeared 1 year after the surgery, the second line chemotherapy (CDDP and 5FU) was performed. The response of the chemotherapy was not observed, and thus the patient was enrolled in the clinical trial of MAGE-A3 peptide vaccine with OK-432. The peptide (300 mg) was injected subcutaneously at the upper thigh or upper arm a total of 6 times over 2 months (days 1, 8, 15, 22, 36, and 50) with OK432. During two courses of the vaccinations, the tumor markers (CA19-9 and CEA) decreased markedly. Furthermore, the tumor size of the lung and liver metastases decreased to 30% of their pre-treatment size. The delayed type hypersensitive reaction became positive after the first course of vaccinations. The precursor CTL for the peptide in the peripheral blood had increased after the vaccination. MAGE-A3 peptide vaccination with OK-432 has a potential to induce immunological response and clinical response in advanced lung cancer patients.

Abstract
"Cancer-germline" genes such as those of the MAGE family are expressed in many tumors and in male germline cells, but are silent in other normal tissues. They encode tumor specific antigens that are used in cancer immunotherapy trials. MAGE-4 antigens represent promising targets for cancer immunotherapy because gene MAGE-4 is expressed in more than 50% of carcinomas of the esophagus, lung, bladder, and head and neck. To identify new MAGE-4 antigenic peptides, we have folded HLA-A*2402 soluble molecules with candidate peptide NYKRCFPVI, which corresponds to amino acids 143 to151 of the MAGE-4 protein. A24/MAGE-4 multimers were used to isolate a cytolytic T cell clone that recognized the MAGE-4 peptide from the blood cells of a donor without cancer. This clone lysed specifically A24 carcinoma cells expressing MAGE-4. The antigenic peptide is processed more efficiently in tumor cells pre-treated with IFN-gamma. This MAGE-4 peptide could represent an interesting target for immunotherapy because it is presented by HLA-A24 molecules, which are widely expressed in different ethnic groups.

Abstract
BACKGROUND Differences in HLA allele frequencies between the diseased and healthy populations may signify efficient immune responses, a notion that has been successfully tested for infectious diseases or for association with genetic elements involved in a distinct type of immunity. This retrospective study is intended to detect differences in MHC class I carrier frequencies of advanced melanoma patients compared to healthy bone marrow donors. METHODS The HLA-A and -B carrier frequencies of 748 stage IV melanoma patients retrieved from serotyping at 6 different centers in Germany were compared using a chi-square test to 13,386 fully HLA typed bone marrow donors registered in the German national bone marrow donor registry. RESULTS The comparison of HLA carrier frequencies in advanced cancer patients with healthy bone marrow donors revealed a significant decrease in HLA-B8 carrier frequencies, which was also apparent in patients with advanced disease compared to patients with loco-regional disease. CONCLUSION The data suggest that protective immune responses restricted to distinct MHC class I molecules may be operational in a subset of melanoma patients, which is the prerequisite for a large scale screen for the corresponding epitopes. Alternatively, the known association of the ancestral haplotype HLA-A1, -B8 and -DR3 with genetic elements such as distinct TNF-alpha alleles might have a protective effect on disease progression. In any case, identification of the cause of protection within this patient subset might lead to a significant improvement in the efficacy of current immunotherapeutic approaches.

Abstract
We describe an HLA-A1 melanoma patient who has mounted a spontaneous cytolytic T cell (CTL) response against an antigenic peptide encoded by gene MAGE-A3 and presented by HLA-A1. The frequency of anti-MAGE-3.A1 CTLp was 5 x 10(-7) of the blood CD8 cells, with a dominant clonotype which was present in six out of seven independent anti-MAGE-3.A1 CTL clones. After vaccination with a recombinant poxvirus coding for the MAGE-3.A1 antigen, the blood frequency of anti-MAGE-3.A1 CTLp increased tenfold. Twenty-two independent CTL clones were derived. Surprisingly, only one of them corresponded to the dominant clonotype present before vaccination. Two new clonotypes were repeated 12 and 7 times, respectively. Our interpretation of these results is that the spontaneous anti-MAGE-3.A1 CTL response pre-existing to vaccination was polyclonal, and that the vaccine restimulated only some of these clones. To estimate the incidence of spontaneous anti-MAGE-3.A1 CTL responses in melanoma patients with a tumor expressing gene MAGE-A3, we measured the blood frequency of anti-MAGE-3.A1 T cells in 45 patients, and found only two clear responses.

Abstract
Available data have led to a controversy on the relationship between human leukocyte antigen (HLA) and cutaneous malignant melanoma susceptibility or prognosis. Moreover, the influence of HLA-C on melanoma has not yet been well established. Therefore, the aim of the current study was to analyze the possible influence of the HLA system on melanoma susceptibility and prognosis in the Spanish population. For this purpose, HLA-A and HLA-B serotyping and HLA-C, HLA-DRB1, and HLA-DQB1 genotyping by polymerase chain reactions using sequence-specific oligonucleotide (PCR-SSO) and sequence-specific primer (PCR-SSP) were performed in 174 melanoma patients and 227 ethnically matched controls. The number of controls was increased up to 356 for HLA-C typing. Patients were stratified according to the histological subtypes of melanoma, sentinel lymph node status, tumor thickness, and ulceration of primary lesion. No HLA-A, HLA-B, HLA-DRB1, or HLA-DQB1 relationship with melanoma was observed for susceptibility or disease prognosis. However, the analysis of HLA-C locus showed that individuals homozygous for HLA-C(Lys80) were significantly more frequent within the patient than the control group. Remarkably, individuals homozygous for group 2 HLA-C alleles (HLA-C(Lys80)) seem to be associated with metastatic progression of melanoma. In contrast, we found a negative association between group 1 HLA-C alleles (HLA-C(Asn80)) and disease susceptibility or metastasis development. In conclusion, although an association with HLA-A, HLA-B, HLA-DRB1, or HLA-DQB1 was not demonstrated, the study of the HLA-C locus revealed that the analysis of the dimorphism at position 80 in the alpha1 helix may help to evaluate the risk and prognosis of melanoma in our population.

Abstract
PurposeTo evaluate the toxicity, antitumoral effectiveness, and immunogenicity of repeated vaccinations with ALVAC miniMAGE-1/3, a recombinant canarypox virus containing a minigene encoding antigenic peptides MAGE-3168-176and MAGE-1161-169, which are presented by HLA-A1 and B35 on tumor cells and can be recognized by cytolytic T lymphocytes (CTLs).Materials and MethodsThe vaccination schedule comprised four sequential injections of the recombinant virus, followed by three booster vaccinations with the MAGE-3168-176and MAGE-1161-169peptides. The vaccines were administered, both intradermally and subcutaneously, at 3-week intervals.ResultsForty patients with advanced cancer were treated, including 37 melanoma patients. The vaccines were generally well tolerated with moderate adverse events, consisting mainly of transient inflammatory reactions at the virus injection sites. Among the 30 melanoma patients assessable for tumor response, a partial response was observed in one patient, and disease stabilization in two others. The remaining patients had progressive disease. Among the patients with stable or progressive disease, five showed evidence of tumor regression. A CTL response against the MAGE-3 vaccine antigen was detected in three of four patients with tumor regression, and in only one of 11 patients without regression.ConclusionRepeated vaccination with ALVAC miniMAGE-1/3 is associated with tumor regression and with a detectable CTL response in a minority of melanoma patients. There is a significant correlation between tumor regression and CTL response. The contribution of vaccine-induced CTL in the tumor regression process is discussed in view of the immunologic events that could be analyzed in detail in one patient.

Abstract
The lack of sufficient well-defined tumor-associated antigens is still a drawback on the way to a cytotoxic T-lymphocyte-based immunotherapy of renal cell carcinoma (RCC). We are trying to define a larger number of such targets by a combined approach involving HLA ligand characterization by mass spectrometry and gene expression profiling by oligonucleotide microarrays. Here, we present the results of a large-scale analysis of 13 RCC specimens. We were able to identify more than 700 peptides, mostly from self-proteins without any evident tumor association. However, some HLA ligands derived from previously known tumor antigens in RCC. In addition, gene expression profiling of tumors and a set of healthy tissues revealed novel candidate RCC-associated antigens. For several of them, we were able to characterize HLA ligands after extraction from the tumor tissue. Apart from universal RCC antigens, some proteins seem to be appropriate candidates in individual patients only. This underlines the advantage of a personalized therapeutic approach. Further analyses will contribute additional HLA ligands to this repertoire of universal as well as patient-individual tumor antigens.

Abstract
The use of tumor antigen-loaded dendritic cells (DC) is one of the most promising approaches to inducing a tumor-specific immune response. We compared electroporation of mRNA to lentiviral transduction for the delivery of tumor antigens to human monocyte-derived and murine bone marrow-derived DC. Both lentiviral transduction and mRNA electroporation induced eGFP expression in on average 81% of human DC. For murine DC, eGFP mRNA electroporation (62%) proved to be more efficient than lentiviral transduction (47%). When we used tNGFR as a transgene we observed lentiviral pseudotransduction that overestimated lentiviral efficiency. Neither gene transfer method had an adverse effect on viability, phenotype, or allostimulatory capacity of either human or murine DC. Yet, the mRNA-electroporated DC showed a reduced production of IL-12p70 compared to their lentivirally transduced and unmodified counterparts. Human Ii80MAGE-A3-modified DC and murine Ii80tOVA-modified DC were able to present antigenic epitopes in the context of MHC class I and class II. Both types of modified murine DC were able to induce OVA-specific cytotoxic T cells in vivo; however, the mRNA-electroporated DC were less potent. Our data indicate that this may be related to their impaired IL-12 production.

Abstract
Transfection with RNA is an attractive method of Ag delivery to dendritic cells (DCs), but has not yet been standardized. We describe in this study the methods to efficiently generate an optimized mature monocyte-derived DC vaccine at clinical scale based on the electroporation of several RNAs either into immature DC followed by maturation or, alternatively, directly into mature DCs, which has not been possible so far with such high efficiency. Electroporation of DCs resulted in high yield, high transfection efficiency (>90%), and high migration capacity. Intracellular staining allowed the study of the expression kinetics of Ags encoded by the transfected RNAs (MelanA, MAGE-3, and survivin) and a validation of the vaccine (>/=90% transfection efficiency). Expression of all three Ags peaked 3-4 h after electroporation in DC transfected either before or after maturation, but decreased differently. The DC vaccine can also be cryopreserved and nevertheless retains its viability, stimulatory capacity as well as migratory activity. In addition, we uncover that DC transfected after rather than before maturation appear to be preferable vaccines not only from a production point of view but also because they appear to be immunologically superior for CTL induction in sharp contrast to common belief. DCs transfected after maturation not only more effectively generate and present the Mage-3.A1 and MelanA.A2.1 epitopes to T cell clones, but they even are superior in priming to the standard proteasome-dependent MelanA.A2.1 wild-type prototype tumor epitope, both in terms of T cell expansion and effector function on a per cell basis.

Abstract
'Cancer-germline' genes such as those of the MAGE family are expressed in many tumors and in male germline cells, but are silent in other normal tissues. They encode shared tumor-specific antigens, which have been used in small therapeutic vaccination trials of cancer patients. Gene MAGE-4, which is expressed in more than 50% of carcinomas of esophagus, head and neck, lung, and bladder, has two known alleles. Using PCR amplifications and digestions of the amplified product, we found that one third of the MAGE-4-positive samples expressed MAGE-4a. We folded HLA-A1 tetramers with peptide MAGE-4a169-177 EVDPASNTY, which is homologous to MAGE-1- and MAGE-3-encoded peptides recognized on HLA-A1 by cytolytic T lymphocytes. Blood lymphocytes from an individual without cancer were directly labelled with these A1/MAGE-4 tetramers. The very rare cells that were stained were sorted by flow cytometry and cloned. We isolated a cytolytic T-lymphocyte clone that lyzed specifically cells pulsed with this MAGE-4 peptide and HLA-A1 tumor cells expressing MAGE-4a, demonstrating that this antigenic peptide is processed efficiently in tumor cells. This peptide might therefore be useful for therapeutic antitumoral vaccination.

Abstract
Antigens encoded by MAGE genes are of particular interest for cancer immunotherapy because they are tumor specific and shared by tumors of different histological types. Several clinical trials are in progress with MAGE peptides, proteins, recombinant poxviruses, and dendritic cells (DC) pulsed with peptides or proteins. The use of gene-modified DC would offer the major advantage of a long-lasting expression of the transgene and a large array of antigenic peptides that fit into the different HLA molecules of the patient. In this study, we tested the ability of gene-modified DC to prime rare Ag-specific T cells, and we identified a new antigenic peptide of clinical interest. CD8(+) T lymphocytes from an individual without cancer were stimulated with monocyte-derived DC, which were infected with a second-generation lentiviral vector encoding MAGE-3. A CTL clone was isolated that recognized peptide EGDCAPEEK presented by HLA-Cw7 molecules, which are expressed by >40% of Caucasians. Interestingly, this new tumor-specific antigenic peptide corresponds to position 212-220 of MAGE-2, -3, -6, and -12. HLA-Cw7 tumor cell lines expressing one of these MAGE genes were lysed by the CTL, indicating that the peptide is efficiently processed in tumor cells and can therefore be used as target for antitumoral vaccination. The risk of tumor escape due to appearance of Ag-loss variants should be reduced by the fact that the peptide is encoded by several MAGE genes.

Abstract
We previously described HLA-B35-restricted melanoma tumor-infiltrating lymphocyte responses to frequently expressed melanoma-associated Ags: tyrosinase, Melan-A/MART-1, gp100, MAGE-A3/MAGE-A6, and NY-ESO-1. Using clones derived from these TIL, we identified in this study the corresponding epitopes. We show that five of these epitopes are new and that melanoma cells naturally present all the six epitopes. Interestingly, five of these epitopes correspond to or encompass melanoma-associated Ag epitopes presented in other HLA contexts, such as A2, A1, B51, and Cw3. In particular, the HLA-B35-restricted Melan-A epitope is mimicked by the peptide 26-35, already known as the most immunodominant melanoma epitope in the HLA-A*0201 context. Because this peptide lacked adequate anchor amino acid residues for efficient binding to HLA-B35, modified peptides were designed. Two of these analogues were found to induce higher PBL- and tumor-infiltrating lymphocyte-specific responses than the parental peptide, suggesting that they could be more immunogenic in HLA-B*3501 melanoma patients. These data have important implications for the formulation of polypeptide-based vaccines as well as for the monitoring of melanoma-specific CTL response in HLA-B*3501 melanoma patients.

Abstract
Vaccination with mature, monocyte-derived dendritic cells (DC) pulsed with the MAGE-3(168-176) peptide, which is presented by HLA-A1, has been reported to induce tumor regressions and CTL in some advanced stage IV melanoma patients. We present here a precise evaluation of the level of some of these anti-MAGE-3.A1 CTL responses and an analysis of their clonal diversity. Blood lymphocytes were stimulated with the MAGE-3.A1 peptide under limiting dilution conditions and assayed with an A1/MAGE-3 tetramer. This was followed by the cloning of the tetramer-positive cells and by TCR sequence analysis of the CTL clones that lysed targets expressing MAGE-3.A1. We also used direct ex vivo tetramer staining of CD8 cells, sorting, and cloning of the positive cells. In three patients who showed regression of some of their metastases after vaccination, CTL responses were observed with frequencies ranging from 7 x 10(-6) to 9 x 10(-4) of CD8(+) blood T lymphocytes, representing an increase of 20- to 400-fold of the frequencies found before immunization. A fourth patient showed neither tumor regression nor an anti-MAGE-3.A1 CTL response. In each of the responses, several CTL clones were amplified. This polyclonality contrasts with the monoclonality of the CTL responses observed in patients vaccinated with MAGE-3.A1 peptide or with an ALVAC recombinant virus coding for this antigenic peptide.

Abstract
We have analyzed the T cell responses of HLA-A1 metastatic melanoma patients with detectable disease, following vaccination with a recombinant ALVAC virus, which bears short MAGE-1 and MAGE-3 sequences coding for antigenic peptides presented by HLA-A1. To evaluate the anti-MAGE CTL responses, we resorted to antigenic stimulation of blood lymphocytes under limiting dilution conditions, followed by tetramer analysis and cloning of the tetramer-positive cells. The clones were tested for their specific lytic ability and their TCR sequences were obtained. Four patients who showed tumor regression were analyzed, and an anti-MAGE-3.A1 CTL response was observed in three of these patients. Postvaccination frequencies of anti-MAGE-3.A1 CTL were 3 x 10(-6), 3 x 10(-3), and 3 x 10(-7) of the blood CD8 T cells, respectively. These three responses were monoclonal. No anti-MAGE-1.A1 CTL response was observed. These results indicate that, like peptide immunization, ALVAC immunization produces monoclonal responses. They also suggest that low-level antivaccine CTL responses can initiate a tumor regression process. Taken together, our analysis of anti-MAGE-3.A1 T cell responses following peptide or ALVAC vaccination shows a degree of correlation between CTL response and tumor regression, but firm conclusions will require larger numbers.

Abstract
BACKGROUND Dendritic cells (DC) are the professional antigen-presenting cells of the immune system, fully equipped to prime naive T cells and thus essential components for cancer immunotherapy. METHODS We tested the influence of several elements (cPPT, trip, WPRE, SIN) on the transduction efficiency of human DC. Human and murine DC were transduced with tNGFR-encoding lentiviruses to assess the effect of transduction on phenotype and function. Human DC were transduced with lentiviruses encoding huIi80MAGE-A3 and murine DC with huIi80tOVA to test antigen presentation. RESULTS A self-inactivating (SIN) lentiviral vector containing the trip element was most efficient in transducing human DC. The transduction of DC with trip/SIN tNGFR encoding lentiviral vectors at MOI 15 resulted in stable gene expression in up to 94.6% (murine) and 88.2% (human) of the mature DC, without perturbing viability, phenotype and function. Human huIi80MAGE-A3-transduced DC were able to stimulate MAGE-A3-specific CD4(+) and CD8(+) T cell clones and could prime both MAGE-A3-specific CD4(+) and CD8(+) T cells in vitro. Murine huIi80tOVA-transduced DC were able to present OVA peptides in the context of MHC class I and class II in vitro and induced a strong OVA-specific cytotoxic T lymphocyte response in vivo, that was protective against subsequent challenge with OVA-expressing tumor cells. CONCLUSIONS We show that, using lentiviral vectors, efficient gene transfer in human and murine DC can be obtained and that these DC can elicit antigen-specific immune responses in vitro and in vivo. The composition of the transfer vector has a major impact on the transduction efficiency.

Abstract
Following vaccination with defined tumor antigens that are recognized by T cells, a small proportion of cancer patients display tumor regressions. Several reports describe anti-vaccine T-cell responses, evaluated with a variety of methods, for example, by assessing T-cell function or expression of specific TCR. However, a correlation between these T-cell responses and the tumor regressions has not yet been established. It appears that some patients display tumor regression with an unexpectedly low frequency of anti-vaccine T cells.

Abstract
'Cancer-germline' genes such as those of the MAGE family are expressed in many tumors and in male germline cells, but are silent in normal tissues. They encode shared tumor-specific antigens, which have been used in therapeutic vaccination trials of cancer patients. MAGE-A4 is expressed in more than 50% of carcinomas of esophagus, head and neck, lung, and bladder. We report here the identification of a new MAGE-A4 encoded peptide, which is recognized by a cytolytic T lymphocyte (CTL) clone on HLA-B*3701. The sequence of the peptide is SESLKMIF. It corresponds to the MAGE-A4156-163 protein sequence. When tumor cells expressing MAGE-A4 were transfected with HLA-B*3701, they were recognized by the CTL clone, demonstrating that the peptide ought to be processed in tumor cells and could therefore serve as a target for therapeutic antitumoral vaccination.

Abstract
The first tumor-specific shared antigens and the cancer-germline genes that code for these antigens were identified with antitumor cytolytic T lymphocytes obtained from cancer patients. A few HLA class I-restricted antigenic peptides were identified by this 'direct approach'. A large set of additional cancer-germline genes have now been identified by purely genetic approaches or by screening tumor cDNA expression libraries with the serum of cancer patients. As a result, a vast number of sequences are known that can code for tumor-specific shared antigens, but most of the encoded antigenic peptides have not yet been identified. We review here recent 'reverse immunology' approaches for the identification of new antigenic peptides. They are based on in vitro stimulation of naive T cells with dendritic cells that have either been loaded with a cancer-germline protein or that have been transduced with viruses carrying cancer-germline coding sequences. These approaches have led to the identification of many new antigenic peptides presented by class I or class II molecules. We also describe some aspects of the processing and presentation of these antigenic peptides.

Abstract
'Cancer-germline' genes such as the MAGE gene family are expressed in many tumors and in male germline cells but not in normal tissues. They encode shared tumor-specific antigens, which have been used in therapeutic vaccination trials of metastatic melanoma patients. To establish whether there is a correlation between tumoral regressions and T-cell responses against the vaccine antigen, we evaluated the responses of patients vaccinated with a MAGE-3 antigenic peptide or a recombinant virus coding for the peptide. Blood lymphocytes were stimulated with antigenic peptide followed by detection with tetramer, T-cell cloning, and TCR analysis. In 4/9 regressor patients and in 1/14 progressors we found a low level, usually monoclonal cytolytic T lymphocyte response against the MAGE-3 peptide.

Abstract
Antigens encoded by MAGE genes are of particular interest for cancer immunotherapy because of their tumoral specificity and because they are shared by many tumors. Antigenic peptide MEVDPIGHLY, which is encoded by MAGE-3 and is known to be presented by human leukocyte antigen (HLA)-B44, is currently being used in therapeutic vaccination trials. We report here that a cytolytic T lymphocyte (CTL) clone, which is restricted by HLA-B*1801, recognizes the same peptide and, importantly, lyzes HLA-B18 tumor cells expressing MAGE-3. These results imply that the use of peptide MEVDPIGHLY can now be extended to HLA-B18 patients. We also provide evidence that, under limiting amounts of protein MAGE-3, HLA B*1801 and B*4403 compete for binding to the peptide.

Abstract
The identification of antigens recognised on human tumours by autologous T-lymphocytes has opened the way for vaccination strategies involving defined tumour antigens. These vaccinations are therapeutic, i.e. they involve patients with detectable disease. Tumour regressions have been observed in a minority of melanoma patients in Phase I/II trials. Some of these regressions have been complete and long lasting. Improving the efficacy of therapeutic vaccines will critically depend on their capacity to trigger a robust immune response, on the development of appropriate methods to monitor these antitumour immune responses to vaccination and on a better understanding of the mechanisms used by tumours to escape immune attack. Finally, the initiation of large randomised Phase III trials will determine the impact of these vaccines on melanoma treatment.
