Research Abstract

Fully understanding of immune surveillance and regulation against cancers is needed to develop early-diagnosis and made-to-order immunotherapy for cancers by using cancer-specific peptides. In this study, SART-1 was identified to have strongest antigenicity among various cancer-specific peptides expressed on oral cancersand to play a central part in immune surveillance against oral cancers, indicating that SART-1 is most promisingly applicable to the treatment and diagnosis of oral cancers.In contrast, it was revealed that a tumor-associated antigen, RCAS1, was expressed on and secreted from oral cancers, induced apoptosis of activated T cells, and thussuppressed immune surveillance against oral cancers. To augment immune surveillance against oral cancers, it was strongly suggested that functional regulation of RCAS1, as well as inoculation of SART-1, should be achieved.
