Identification of H2-Db and HLA-A2 Specific CD8 Epitopes from Human KDR/VEGFR-2 that Inhibit Angiogenesis by Vaccination

Posted Jun 15 2010 5:00pm

Description of Invention:
Vascular Endothelial Growth Factor Receptor 2 (VEGFR-2/KDR) is a promising target for cancer therapy due to its critical role in tumor associated angiogenesis and vascularization. This invention describes the amino acid sequences of seven short peptides based upon epitopes of human Vascular Endothelial Growth Factor Receptor-2 (VEGFR-2) that bind human Histocompatibility Leukocyte Antigen A2 (HLA-A2). These peptides can potentially induce Cytotoxic T Lymphocyte (CTL)-mediated lysis of tumor vascularization and inhibit tumor growth. The inventors have demonstrated the principles described in this invention in vivo in mice for VEGFR-2, using murine H2-Db specific peptides instead of HLA-A2. This invention has the potential to inhibit angiogenesis and may be applicable to tumor and autoimmune disease therapy.
