Abstract: A set of target peptides are presented by HLA A*0201 on the surface of ovarian cancer cells. They are envisioned to among other things (a) stimulate an immune response to the proliferative disease, e.g., ovarian cancer, (b) function as immunotherapeutics in adoptive T-cell therapy or as a vaccine, (c) facilitate antibody recognition of tumor boundaries in surgical pathology samples, (d) act as biomarkers for early detection and/or diagnosis of the disease, and (e) act as targets in the generation antibody-like molecules which recognize the target-peptide/MHC complex.

Abstract: A set of target peptides are presented by HLA A*0201, B*0301, B*0702 and B*2705 on the surface of disease cells. They are envisioned to, among other things, stimulate an immune response to the proliferative disease, e.g., colorectal cancer, to function as immunotherapeutics in adoptive T cell therapy or as a vaccine, facilitate antibody recognition of tumor boundaries in surgical pathology samples, act as biomarkers for early detection and/or diagnosis of the disease, and/or act as targets in the generation antibody-like molecules which recognize the target-peptide/MHC complex.

Abstract: Adaptive immune responses rely on the ability of cytotoxic T cells to identify and eliminate cells displaying disease-specific antigens on human leukocyte antigen (HLA) class I molecules. Investigations into antigen processing and display have immense implications in human health, disease and therapy. To extend understanding of the rules governing antigen processing and presentation, immunopurified peptides from B cells, each expressing a single HLA class I allele, were profiled using accurate mass, high-resolution liquid chromatography-mass spectrometry (LC-MS/MS). A resource dataset containing thousands of peptides bound to 28 distinct class I HLA-A, -B, and -C alleles was generated by implementing a novel allele-specific database search strategy. Applicants discovered new binding motifs, established the role of gene expression in peptide presentation and improved prediction of HLA-peptide binding by using these data to train machine-learning models.
