A peptide-based cancer vaccine containing a mutated form of the HLA-A*0201-restricted cytomegaloviral epitope CMVpp65(495-503) with potential immunostimulatory and antitumor activities. Upon subcutaneous administration, CMVpp65-A*0201 peptide vaccine may stimulate a cytotoxic T lymphocyte (CTL) response against CMV-positive cells, resulting in cell lysis. HLA-A*0201 is an MHC class I molecule that presents antigenic peptides to CD8+ T cells; epitope design restricted to epitopes that bind most efficiently to HLA-A*0201 may improve antigenic peptide immunogenicity. CMVpp65, a tegument protein of the herpes virus CMV, is the main viral antigen found in peripheral blood mononuclear cells (PBMCs) after viral infection and may activate cell-mediated immunity.
