Mimotopes of cytolytic T lymphocytes in cancer immunotherapy

Rap d identification of the cytolytic T lymphocyte (CTL) epitopes that are presented by cancer cells will provide the basis for manipulation of tumor immunity but remains a major chal enge in the field. By screening randomly synthesized peptide libraries, mimotopes for tumor-reactive CTLs can be readily constructed and they may be functionally equal to or potentially more potent than natural peptides in stimulating CTL responses; therefore, the peptide library approach provides great promise for design of cancer vaccines and adoptive tumor immunotherapy.
