NCIt definition : A cell-based vaccine consisting of autologous HLA-A2*0201-restricted dendritic cells
(DC), which were derived from patient-harvested adherent peripheral blood monocytes
cultured in vitro with granulocyte-macrophage colony-stimulating factor (GM-CSF) and
interleukin-4 (IL-4), that were pulsed with a peptide fragment comprised of amino
acid residues 26 through 35 of melanoma antigen recognized by T-cells 1 (MART-1 (26-35)),
with potential immunostimulatory and antineoplastic activities. Upon intradermal vaccination,
autologous DC pulsed with MART-1 (26-35) peptide may stimulate the host immune system
to mount a cytotoxic T-lymphocyte immune response against tumor cells expressing MART-1.
MART-1, a protein involved in melanosome biogenesis, is overexpressed by melanoma
cells. The MART-1 (26-35) peptide is highly immunogenic for the HLA-A2*0201 haplotype.;
