Strategies to deliver defined or whole antigens to DCs. DCs used for cancer vaccines have been generated from the peripheral blood monocytes of the patients using cytokines including GM-CSF and IL-4. To generate antigen-specific CTL response against tumor cells, DCs have been loaded with defined or whole tumor-associated antigens. For example, DCs loaded with synthetic peptide, antigenic DNA, or RNA have been used. Moreover, whole tumor-associated antigens including defined and unidentified have been also loaded to DCs.
