We studied the feasibility of using single-wall carbon nanotubes (SWNTs) as antigen carriers to improve immune responses to peptides that are weak immunogens, a characteristic typical of human tumor antigens. Binding and presentation of peptide antigens by the MHC molecules of antigen presenting cells (APCs) is essential to mounting an effective immune(More)
Natural killer (NK) cells are important effectors of innate immunity. In contrast to many studies of interleukin-2 (IL-2)-activated NK cells, the physiologic requirements for stimulating resting NK cells have only recently received attention. Given the emerging variety of dendritic cell (DC) types and their division of labor for stimulating immunity, we(More)
Cyclin D1 is over-expressed in various human tumors and therefore can be a potential oncogenic target antigen. However, only a limited number of T cell epitopes has been characterized. We aimed at identifying human cyclin D1-derived peptides that include both CD4 and CD8 T cell epitopes and to test if such multi-epitope peptides could yield improved(More)
Wilms tumor protein (WT1) is a transcription factor selectively overexpressed in leukemias and cancers; clinical trials are underway that use altered WT1 peptide sequences as vaccines. Here we report a strategy to study peptide-MHC interactions by incorporating non-natural and photo-reactive amino acids into the sequence of WT1 peptides. Thirteen WT1(More)
Approved therapeutic antineoplastic antibodies have targeted extracellular or cell-surface molecules. ESK1 is the first fully human T-cell receptor-like antibody targeting an intracellular tumor-associated antigen, Wilm's tumor 1 (WT1). In murine xenograft models, ESK1 exhibits a high specificity and exert robust antineoplastic effects against human cancers(More)
The vast majority of cellular proteins, many of which are the most interesting and important molecules for regulating normal and neoplastic growth, lie within the cell, hidden from monoclonal antibody (mAb) therapeutics by the barriers of the plasma membrane. We recently demonstrated in vivo the successful treatment of several human cancers by use of a(More)
