Mechanisms of resistance against B-cell malignancies induced by vaccination against the immunoglobulin receptor: the case for T-cell immunity
- 92 Downloads
Immunoglobulin (Ig) molecules are composed of heavy and light chains that possess highly variable regions at their amino termini. These variable regions combine to form the antigen recognition site, which can itself be recognized as an antigen, termed the idiotype. B-cell malignancies are clonal proliferations of Ig-producing cells. The idiotypic determinants of the surface Ig can thus serve as a tumor-specific marker for the malignant clone. We and others continue to investigate strategies to induce specific immunity against the idiotypic determinants on the Ig molecule expressed and/or secreted by B-cell malignancies by active immunization. This chapter will summarize the progress in exploiting tumor-derived Ig protein as a tumor-specific antigen for therapeutic vaccine development and the priorities for future investigation.
