VEGFR1-1084 peptide vaccine
A peptide vaccine containing an HLA-A*2402-restricted epitope of vascular endothelial growth factor receptor 1 (VEGFR1 or Flt-1) with potential immunostimulating, antiangiogenic, and antineoplastic activities. Upon vaccination, VEGFR1-1084 peptide vaccine may stimulate a cytotoxic T lymphocyte (CTL) response against VEGFR1-expressing endothelial cells of the tumor microvasculature, which may inhibit tumor angiogenesis and tumor cell proliferation. VEGFR1, a receptor tyrosine kinase, may be overexpressed on endothelial cells of the tumor microvasculature and is associated with tumor cell proliferation, invasion and tumor angiogenesis. 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 antigenicity. Check for active clinical trials using this agent. (NCI Thesaurus)
