Scientific Interest(s):

Dr. Sylvia Kiertscher's research focuses on the immune system's response to cancer, including the events which lead to an anti-tumor response, how the tumor evades these responses and what steps can be taken to improve cancer treatment to prevent this evasion.

This goal is being pursued in three main research areas. The first project involves the effects of the tumor microenvironment on the immune response to cancer. Kiertscher's lab has found that factors produced by tumor cells have a striking ability to disrupt dendritic cell maturation and function. The results from this study provide the rationale for clinical interventions to boost the effectiveness of the patient's dendritic cells.

The second project utilizes the Her-2/neu tumor antigen as a model to examine tumor antigen processing and presentation by dendritic cells, and the interactions of these antigen-loaded DC with T-cells, with the ultimate goal of providing for the most effective anti-tumor T-cell responses in cancer patients.

The third project evaluates the use of novel adenoviral vector systems to transduce dendritic cells with tumor antigens or cytokines for gene medicine applications.
