Abstract: |
New approaches to the construction of cancer vaccines focus on the identification and purification of immunogenic cancer antigens and on methods for increasing their immunogenicity. They include preparation of antigens by chemical synthesis or recombinant DNA technology, conjugation of carbohydrate antigens with immunogenic protein carriers to augment T-cell help, use of antiidiotypic antibodies in lieu of antigens, and development of more potent immunologic adjuvants. Against the background of recent advances in the field of antigen presentation, these approaches offer hope for improving the efficacy of cancer vaccines. |
