| Research Abstract |
The expression of GITRL was observed both on leukemic cells and leukemic dendritic cells. The binding of GITRL to GITR on T cells inhibited induction of CDK2, One of the leukemia-associated antigens, -specific cytotoxic T cells (CTL) and restrained CTL activity. The GITR/GITRL interaction also increased indoleamine 2, 3-dioxygenase (IDO) activity even in leukemic cells and inducing kynurenine secretion from leukemic cells. The administration of anti-IDO agents or anti-GITRL blocking Abs combined with CDK2 vaccination may therefore effectively induce CDK2-specific CTLs in unrelated cord blood transplantation recipients.
