Genetic immunotherapy for cancer.
The application of gene therapy to the treatment of human and veterinary diseases offers an innovative addition to the clinician's treatment options. Gene therapy can potentially be used to (1) replace defective or missing genes, (2) treat cancer, and (3) deliver drugs. The focus of this paper is the use of gene therapy in the treatment of cancer. To be effective, genes must be delivered to target cells which can then serve as the factory to produce the gene product. Delivery systems include retroviral vectors, adenoviral vectors, and direct introduction of plasmid DNA into cells. In the case of cancer immunotherapy, introduced genes produce products that enhance tumor immunosurveillance and tumor cell killing by immune mechanisms.
