title: Anti-idiotype cancer vaccines: past and future.
abstract: Anti-idiotypic antibodies (Ab2) binding to the antigen-combining site of antitumor antibodies (Ab1) can induce anti-anti-idiotypic antibodies (Ab3) that specifically bind to the tumor antigen recognized by Ab1. Furthermore, Ab2, mimicking tumor antigens, have been shown to induce anti-anti-idiotypic proliferative T lymphocytes of the helper and suppressor type, as well as cytotoxic lymphocytes. The immunomodulatory activities of Ab2 have been demonstrated both in animals and in patients. The demonstration of tumor growth inhibition by anti-idiotypes in preclinical and phase I clinical studies emphasizes that randomized control trials should be performed to demonstrate clinical efficacy of Ab2 vaccines.
