    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.

    摘要： A front-end reagent ion source for a mass spectrometer is disclosed. Reagent vapor is supplied to a reagent ionization volume located within a chamber of the mass spectrometer and maintained at a low vacuum pressure. Reagent ions are formed by interaction of the reagent vapor molecules with an electrical discharge (e.g., a glow discharge) within the ionization volume, and pass into the chamber of the mass spectrometer. At least one ion optical element located along the analyte ion path transports the reagent ions to successive chambers of the mass spectrometer. The reagent ions may be combined with the analyte ions to perform ion-ion studies such as electron transfer dissociation (ETD).

    摘要： The present invention is based on the identification of a predominant ligand of CD8+ T cells that are responsible for type 1 diabetes. That ligand is islet-specific glucose-6-phosphatase catalytic subunit-related protein (IGRP). Several CD8+ T cell-binding peptides from IGRP are identified, including the peptide comprising amino acids 206-214 of the IGRP sequence, which has high avidity to the most prevalent T cell receptor of pathogenic CD8+ T cells in autoimmune diabetes. The invention thus provides oligopeptide and polypeptide compositions comprising YLKTN(A/I/L/V)FL (SEQ ID NO:3), FLWSVFWLI (SEQ ID NO:4), (T/A)YY(G/T)FLNFM (SEQ ID NO:5), LR(L/V)(F/L)(G/N)IDLL (SEQ ID NO:6), KWCANPDWI (SEQ ID NO:7), and SFCKSASIP (SEQ ID NO:8). Also provided are oligopeptide compositions 8-10 amino acids in length and completely homologous with a mammalian IGRP, where the oligopeptide is capable of binding a human MHC class I molecule. Additionally, various methods of treating a mammal using the above compositions are provided, where the mammal is at risk for or has type 1 diabetes. Also provided are methods of preventing a CD8+ T cell that is cytotoxic to pancreatic islet β-cells from destroying a mammalian β-cell, where the methods also use the above compositions. Further provided are methods for determining whether a mammal is at risk for or has type 1 diabetes, where the methods use the above compositions.
