Abstract
Optimally designed cancer vaccines should combine the best tumor antigens with the most effective immunotherapy agents and delivery strategies to achieve positive clinical results. The unique immunoglobulin (Ig) idiotype on the surface of each B-cell lymphoma represents an ideal tumor-specific antigen for use as a cancer vaccine. It has been theorized that effective cancer vaccines can be developed using the minimum essential subset of T cell and B cell epitopes that comprise the ‘immunome’, the universe of neoplasm-derived peptides that interface with B and T cells of the host immune system. Idiotypic antigenic determinants of a B-cell lymphoma lie within the hypervariable regions and mainly within the complementarity-determining regions (CDR)s 3. Thus, the CDR3s are considered a “hot spot” of particular interest for construction of subunit vaccines. DNA vaccines, whose safety and tolerability are substantiated in completed and ongoing clinical trials, have emerged as a novel lymphoma vaccine formulation for antigen-specific immunotherapy. The molecular precision tools offered by gene-based vaccines allow to explore the use of CDR3 sequence as an antilymphoma vaccine.

Programmed Cell Death Genes in Oncology: Pioneering Therapeutic and Diagnostic Frontiers (BMS-CGT-2024-HT-45)
Programmed Cell Death (PCD) is recognized as a pivotal biological mechanism with far-reaching effects in the realm of cancer therapy. This complex process encompasses a variety of cell death modalities, including apoptosis, autophagic cell death, pyroptosis, and ferroptosis, each of which contributes to the intricate landscape of cancer development and ...read more
