Self-Tolerance Does Not Restrict the CD4+ T-Helper Response against the p53 Tumor Antigen

Abstract excerpt

Tumorigenesis is frequently associated with mutation and overexpression of p53, which makes it an attractive target antigen for T cell-mediated immunotherapy of cancer. However, the magnitude and breadth of the p53-specific T-cell repertoire may be restricted due to the ubiquitous expression of wild-type p53 in normal somatic tissues. In view of the importance of the CD4+ T-helper cell responses in effective...
