Abstract
This meeting reported on a number of new methods developed for breaking immune tolerance and generating robust immune responses to tumors, which were previously thought to be non-immunogenic. These findings have great therapeutic potential; at the cellular level, T-cell anergy induced by TGF[beta] could potentially be inhibited by upregulation of Smad7 in T-cells. Furthermore, cytotoxic T-cells could be raised to tumor antigens, and tumors can be eliminated by blocking the T-cell downregulatory surface marker CTLA-4 with antibodies. Finally, therapeutic levels of tumor-specific cytotoxic T-cells could be induced to non-immunogenic tumor antigens by targeting them to DCs; this was achieved by conjugating the tumor antigens to the CCR6 chemokine ligand HBD2
