Background: Our previous predictive peptide binding studies indicated that a novel 20-mer multiple antigen peptide, CH401MAP, containing an anti-human epidermal growth factor receptor 2 (HER2) monoclonal antibody epitope (N163-182), may potentially bind to more than 95% of class I human leukocyte antigens (HLAs) and to 30-50% of class II HLAs expressed on peripheral blood mononuclear cells (PBMCs). In this study, CH401MAP was used for in vitro stimulation of PBMCs obtained from Japanese breast cancer patients, and anti-CH401MAP antibody secretion was evaluated.
Methods: PBMCs of breast cancer patients were stimulated with CH401MAP peptide in vitro. Eight days after stimulation, the culture supernatants were collected and the anti-CH401MAP antibody levels were determined using enzyme-linked immunosorbent assay . The correlation of the antibod.. View More»
