CTAs are normally expressed only in germ cells of the testis but become aberrantly re-expressed in many cancers, including melanoma, lung, ovarian, and esophageal tumors. Because the testis is an immune-privileged site, the immune system does not develop tolerance to these antigens—making them highly attractive targets for cancer immunotherapy and immune monitoring. These characteristics have positioned NY-ESO-1, and epitopes like RLLEFYLAM, at the center of research into cancer vaccines, adoptive T cell therapies, and diagnostic assays. T cell epitope cluster NY-ESO-1 86–94 (RLLEFYLAM) is part of an immunodominant cluster.
