Theory and Practice of Immunotherapy Directed against the PRAME Antigen
Abstract
The preferentially expressed antigen of melanoma (PRAME) is a significant target for monoclonal antibodies and an oncospecific marker known for its activity on all the tumor cell differentiation stages and its eliciting of a spontaneous T-cell response. Since PRAME protein is active in approximately every second patient with solid tumors and oncohematological diseases, anti-PRAME immunotherapy is very promising. In current review the mechanism of spontaneous immune response against PRAME is discussed as well as the role of this antigen in immunosurveillance. The review deals with the PRAME-specific T-cell genesis and risk assessment of immunotherapy directed against PRAME-positive cells. The risks and benefits of various immunotherapy approaches including the use of dendritic cell vaccines, PRAME vaccination, development of specific T-cells, and development of specific monoclonal antibodies were analysed. Possible causes of treatment failure are analysed, and methods of overcoming them are suggested. The literature search in the Pubmed, Scopus, and eLibrary databases, with the use of “PRAME” as a keyword was performed. Only publications related to various aspects of immunotherapy and anti-PRAME-specific agents were included in the review.
