摘要:
A set of phosphorylated peptides are presented by HLA A*0101, A*0201, A*0301, B*4402, B*2705, B*1402, and B*0702 on the surface of melanoma cells. They have the potential to (a) stimulate an immune response to the cancer, (b) to function as immunotherapeutics in adoptive T-cell therapy or as a vaccine, (c) to facilitate antibody recognition of the tumor boundaries in surgical pathology samples, and (d) act as biomarkers for early detection of the disease. Phosphorylated peptides are also presented for other cancers.
摘要:
We characterized a total of 175 HLA-DR-associated phosphopeptides using sequential affinity isolation, biochemical enrichment, mass spectrometric sequencing and comparative analysis. Many were derived from source proteins which may have roles in cancer development, growth and metastasis. Most were expressed exclusively by either melanomas or transformed B cells, suggesting the potential to define cell type-specific phosphatome “fingerprints”. We generated HLA-DRβ1*0101-restricted CD4+ T cells specific for a phospho-MART-1 peptide identified in two melanoma cell lines. These T cells showed specificity for phosphopeptide-pulsed antigen presenting cells as well as for intact melanoma cells. MHC II-restricted phosphopeptides recognizable by human CD4+ T cells are potential targets for cancer immunotherapy.

Melanoma-specific, A1- and A3-restricted CTL epitopes have been identified in tyrosinase and pMel-17, respectively, and may be used in the design of vaccines.
摘要:
Peptide sequences constituting T-cell epitopes of minor Histocompatibility antigen, HA-1. HA-1 is associated with Graft versus Host Disease. The peptides and their derivatives find many uses, for instance, in bone marrow transplantation, organ transplantation and in treatment of leukemia and non-hematopoietic tumors. The peptide and/or its derivatives can be incorporated in vaccines, in pharmaceutical formulations and they can be used in diagnostic test kits. HA-1 is expressed by non-hematopoietic tumor cells. While absent in normal epithelial cells, tumor cells and tumor cell lines, particularly from epithelial origin, express HA-1 and are recognized by HA-1 cytotoxic T-cells. The invention provides means and methods for HA-1 specific immunotherapy for HA-1-positive patients with non-hematopoietic tumor cells.

Cysteine-depleted CTL epitopes can elicit a stronger or more specific CTL response than the native, cysteine-containing CTL epitope of a disease associated antigen.
摘要:
A peptide sequence of the so-called minor H antigen. The minor H antigens are associated with Graft versus Host disease. The peptide and its derivatives find many uses in bone marrow transplantation, organ transplantation, and in the treatment of leukemia. The peptide and its derivatives can be incorporated into vaccines and pharmaceutical formulations, and they can be used in diagnostic test kits. The peptide is derived from the HA-1 minor antigen, and has the sequence VLXDDLLEA (SEQ ID NO: 1), wherein X represents a histidine or arginine residue. Both donors and recipients in bone marrow transplantation can be treated with the peptides, optionally in combination with other peptides, coupled to carriers, and with suitable excipients and/or adjuvants.

摘要:
The present invention relates to a peptide which is immunologically recognizable as a T cell epitope of the minor Histocompatibility antigen H-Y. The peptide comprises amino acid sequence SPSVDKARAEL (SEQ ID NO: 1) or FIDSYICQV (SEQ ID NO: 2). The peptide is obtainable from the minor Histocompatibility antigen H-Y. Providing a toxic moiety to the peptide eliminates T cells having specific binding affinity for the peptide. The peptide induces tolerance for transplantations when administered to H-Y-negative recipients.
