NCIt definition : A cancer vaccine adjuvant consisting of a recombinant fowlpox virus encoding human
granulocyte-macrophage colony-stimulating factor (GM-CSF). GM-CSF binds to specific
cell surface receptors on various immuno-hematopoietic cell types, enhancing their
proliferation and differentiation and stimulating macrophage and dendritic cell functions
in antigen presentation and antitumor cell-mediated immunity. Administration of recombinant
fowlpox GM-CSF vaccine adjuvant may induce an immune response against tumor cells.
Fowlpox virus is an attractive vector because its genome is easy to manipulate and
it is replication incompetent in mammalian cells.;
