NCIt definition : A cancer vaccine consisting of a recombinant fowlpox virus encoding human prostate-specific
antigen (PSA) and TRICOM, a combination of three immunostimulants (i.e., B7.1, ICAM-1,
and LFA-3). Administration of this agent may induce a cytotoxic T cell response against
PSA-expressing tumor cells. Dendritic cells infected with TRICOM vectors greatly enhance
naive T-cell activation and peptide-specific T-cell stimulation. Fowlpox virus is
an attractive vector because its genome is easy to manipulate and it is replication
incompetent in mammalian cells.;
