Abstract:
Cancer vaccines are entering a new phase of popularity, in part because of the recognition of when a therapeutic vaccine is most effective and the identification of appropriate target antigens. New technologies, most notably gene transfection into dendritic cell and DNA vaccination approaches, have spurred further clinical evaluations. While many researchers consider humoral responses as not being viable for large tumors, these responses may play a role in regulating micrometastases (i.e., adjuvant setting). The recent approval of antibodies as therapeutics for cancer treatment has lent to the viability of this therapy concept. The success of carbohydrate-conjugate vaccines in bacterial systems has also renewed interest in developing such vaccines for cancer immunotherapy. Carbohydrates can be further converted into peptide/protein mimetics with several of these mimetics in clinical trials. These mimetic forms can be manipulated into DNA vaccine types that may be combined into DNA cassettes that contain CTL-associated epitopes to further define a novel strategy for future vaccine development.
