p53 as a target for anti-cancer immunotherapy

Abstract

The key to specific and non-toxic cancer therapy is likely to be identification and targeting of processes that are absolutely unique to the tumor. One such approach is to target cells expressing mutations in the oncoproteins that led to the development of the cancer, such as p53. In animal model systems, highly mutant p53-specific cytotoxic T cells can be induced, but it remains to be seen whether this can be translated into clinical practice, and what proportion of tumors will respond. In this review, the potential and problems of immunological targeting of mutant p53 in solid tumors are discussed.
