Research Abstract

HCC is usually associated with cirrhosis and often recurs even after complete treatment of the tumors in the remaining part of the cirrhotic liver. Thus, there is a strong need for the development of a new intervention therapy that suppresses the occurrence or recurrence of HCC effectively and that has fewer side effects. Immunotherapy may be such a treatment and may be applicable to the clinical treatment of HCC. Restricted and high-level expression of Glypican-3 in a majority of human HCC makes this protein an attractive vaccine target. Here we described the identification of the new Glypican-3 peptide as a HLA restricted CTL epitope.
