Research Abstract

To elucidate the SCLC antigens that are recognized by Th17 cells, we examine surface molecules of SCLC cells and found that the floating SCLC cells express CD133, which is one of putative cancer stem cell (CSC) markers. Proteome analyses revealed DEAD/H (Asp-Glu-Ala-Asp/His) box polypeptide 3, X-linked (DDX3X) as a novel CSC-specific protein. An anti-DDX3X vaccination induced anti-CSC effector T cells that mediated antitumor therapeutic efficacy. DDX3X was highly expressed in human CD133^+ SCLC cells but not in normal epithelial cells. These results indicate that anti-DDX3X, immunotherapy to induce Th17 is a promising treatment option in the clinical setting.
