Research Interests

Cancer

The research program focuses on understanding of the molecular mechanism of the interaction between the immune system and tumor cells particularly the caner-induced immune suppression, and utilizing this understanding for the development of novel immune therapeutics and vaccines against cancer. The group Designed, and conducted some of the first cancer vaccine clinical trials directed against specific genetic changes in cancer cells.

Currently, the group works on understanding the mechanisms of the inhibitory arm of the immune system and developing strategies to suppress such mechanisms to enhance therapy against cancer; identifying novel regulation pathways of the T regulatory cells and developing novel strategies to manipulate such pathways to selectively inhibit these cells; developing novel targets for immune therapy including tumor anti-angiogenesis vaccines and vaccines against novel human papilloma virus (HPV); and developing of strategies to enhance the role of the immune system as a forth modality to treat cancer.
