Definition

A cancer vacine containing four HLA-A*2402-restricted peptide epitopes with potential immunostimulatory and antitumor activities. Peptide epitopes in this vaccine are derived from: URLC10 (up-regulated lung cancer 10), TTK (TTK protein kinase), and VEGFRs (vascular endothelial growth factor receptors) 1 and 2. Upon administration, URLC10-TTK-KOC1-VEGFR1-VEGFR2 multipeptide vaccine may stimulate a cytotoxic T lymphocyte (CTL) response against tumor cells expressing URLC10, TTK, VEGFR 1 and 2 peptides, resulting in cell lysis and decreased tumor growth. HLA-A*2402 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*2402 may improve antigenic peptide immunogenicity.
