Abstract
Recently, major advances have been made in the identification of antigens from human melanoma which are recognized by T cells. In spite of this, little is known about the optimal ways to use these antigens to treat patients with cancer. Progress in this area is likely to require accurate preclinical animal models, but the availability of such models has lagged behind developments in human tumor immunology. Whereas many of the identified human melanoma antigens are normal tissue differentiation proteins, analogous murine tumor antigens have not yet been identified. In this paper we identify a normal tissue differentiation antigen, tyrosinase-related protein 2 (TRP-2), expressed by the murine B16 melanoma which was found by screening a cDNA library from B16 with tumor-reactive cytotoxic T lymphocytes (CTL). A peptide conforming to the predicted MHC class I H2-Kb binding motif, TRP-2181-188, was identified as the major reactive epitope within TRP-2 recognized by these anti-B16 CTLs. By site-directed mutagenesis, it was shown that alteration of this epitope eliminated recognition of TRP-2. It was further demonstrated that a CTL line raised from splenocytes by repeated stimulation in vitro with this peptide could recognize B16 tumor and was therapeutic against 3-d-old established pulmonary metastases. The use of TRP-2 in a preclinical model of tumor immunotherapy may be helpful in suggesting optimal vaccination strategies for cancer therapy in patients.

Abstract
A number of Ags recognized by class I-restricted, melanoma-specific T cells have recently been identified. In this report we demonstrated that tumor-infiltrating lymphocytes (TIL) from melanoma patient 1413 recognize a tumor Ag, tyrosinase, in the context of HLA-A24. This Ag had previously been shown to be recognized by an HLA-A24-restricted TIL, TIL 888, as well as HLA-A2-restricted, melanoma-specific T cells isolated from two additional patients. The peptide epitope recognized by TIL 1413 was then identified through the use of sequential deletions of the tyrosinase cDNA, as well as through prediction of HLA-A24 binding peptides based on a previously identified motif. Two peptides, a 9-amino acid peptide (AFLPWHRLF) and an overlapping 10-amino acid peptide (AFLPWHRLFL) containing an additional leucine at the carboxyl terminus, were both recognized by TIL 1413. Anti-peptide-specific CTL could be induced by repeated stimulation of peripheral blood lymphocytes from melanoma patient 1413, and this CTL line specifically recognized both HLA-A24+ B cell lines pulsed with the peptide and HLA-A24+ tyrosinase+ melanoma cells. This peptide thus represents a reagent that may be used to generate melanoma-specific T cells for adoptive immunotherapy, as well as in peptide vaccines for HLA-A24+ melanoma patients.

Abstract
The role of tumor-specific T cells in mediating the regression of metastatic melanoma has been suggested by the clinical response of patients to treatment with tumor-infiltrating lymphocytes (TIL). A number of Ags recognized by class I-restricted melanoma-specific T cells have recently been isolated, raising the hope that this will lead to the development of improved therapies. In this study, we report the cloning of a tumor Ag recognized by T cells from melanoma patient 888. Previously, we reported that TIL 888, grown from the tumor of this patient, recognized tyrosinase in an HLA-A24-restricted fashion. This line, when infused into the autologous patient, resulted in complete regression of multiple metastases. Three years later, a second TIL line, TIL 1290, was isolated from a recurrent pelvic tumor. Infusion of a mixture of TIL 888 and TIL 1290 cell lines into the patient resulted in complete regression of a residual abdominal mass and the patient remains disease-free 2 yr later. The TIL 1290 cell line, which recognized melanoma in an HLA-A24-restricted manner, failed to recognize tyrosinase. TIL 1290 was then used to screen an 888 melanoma cDNA library, and an Ag was isolated that did not correspond to any found in sequence databases. This gene, termed p15, was found to be expressed in a variety of normal tissues, and a peptide epitope recognized by TIL 1290 was found to represent the product of an nonmutated gene. Screening of additional cDNA pools resulted in the isolation of a second clone which stimulated TIL 1290. This clone also appeared to represent a transcript of the p15 gene, indicating that this gene may encode the predominant Ag recognized by TIL 1290.

Abstract
The observation that allogeneic melanoma cells matched for particular HLA class I alleles stimulate T-cells isolated from patients suggests that widely shared antigens exist on these tumors. A transient expression system was developed for screening a melanoma complementary DNA library using the highly transfectable human kidney cell line 293. Using this system, large numbers of complementary DNA clones can be rapidly screened for the expression of antigens which stimulate T-cells. Tumor-infiltrating lymphocytes from patient 888, which recognized melanoma in the context of HLA-A24, were used to screen a complementary DNA library made from the autologous melanoma. Our results demonstrate that these tumor-infiltrating lymphocytes recognize tyrosinase, a gene previously shown to be recognized by T-cells only in the context of HLA-A2. These data demonstrate that a single antigen can be recognized in the context of two different class I HLA alleles. In addition, this study suggests that recognition of tyrosinase by antigen-specific T-cells may be involved in tumor rejection.

Abstract
Genomic clones corresponding to class II beta genes of the SLAc haplotype of miniature swine have been isolated and characterized. These genes have been grouped into seven non-overlapping clusters on the basis of restriction mapping. Ordering of exons within each cluster was accomplished by hybridization of Southern blots of restriction fragments with exon-specific probes. The two clusters (clusters 2 and 3) encoding the DRB and DQB genes were identified on the basis of hybridization with locus-specific 3' untranslated cDNA probes. Cluster 4 contained exons of both DOB and DQB genes, the basis for which remains to be determined. The remaining four clusters (1, 5, 6, 7) were identified as containing DP, DR, and DO coding sequences, respectively, on the basis of sequence analysis. The porcine class II region appears very similar to that of man in number and nature of the class II genes identified and in the intron/exon organization of corresponding genes.

Abstract
Class II genes of miniature swine have been characterized by restriction fragment length polymorphism (RFLP) analysis and by analysis of a series of clones isolated from a lymphocyte genomic library. For RFLP analysis, DNA samples from three independent major histocompatibility complex homozygous lines and three intra-MHC recombinant lines were digested with a variety of restriction enzymes and analyzed in Southern blots using human cDNA probes for DP, DQ, DR, and DZ alpha genes, and DP, DQ, DR, and DO beta genes. One, or at most two, unique fragments were detected by hybridization with each of the human alpha probes tested. In contrast, multiple bands (five to six for most enzymes examined) were detected by each of the human beta probes tested, the majority of which were found to cross-react with at least three of these probes under conditions of moderate stringency. Genomic DNA from the SLAc haplotype was cloned into an EMBL-3 bacteriophage vector, and the corresponding genomic library was screened with each of these human cDNA probes. The class II genes thereby isolated from this library showed characteristics consistent with those anticipated from the RFLP analysis. Thus, unique alpha genes were obtained which showed no evidence of cross-hybridization, while beta genes showed extensive cross-hybridization and were frequently detected in the library by more than one human beta gene probe. These data are consistent with early evolutionary divergence of alpha genes, prior to mammalian speciation, and with continuing evolution of beta genes, with possible shared usage of these genes by different alpha loci. The data also imply that alpha genes can readily be assigned to loci homologous to their human counterparts, but that beta genes will require further mapping and/or sequence analysis to confirm assignments.
