T cell eomesodermin expression for optimal cancer immunotherapy.
Re-activating and directing a cancer patient’s immune system to reject their tumors and eradicate the cancer with minimal toxicity to the patient is the ultimate goal of the cancer immunotherapy field. The field has made great progress, with multiple immunomodulatory antibody therapies already approved and more in the therapeutic pipeline. Additional progress has been seen in recent successful cancer treatment using genetically modified T cell-based therapy. These advances in cancer immunotherapy represent the clinical translation of research into the signals that activate and inhibit cells of the immune system, particularly T cells.
We believe that through understanding the molecular mechanisms by which recent translational approaches have been successful we can establish a strong foundation for the rational design of new approaches to T cell cancer immunomodulatory therapy.
Specifically, we believe that by investigating connections between two of the signaling molecules targeted in developing antibody and cell based Immunotherapeutics, PD-1 and 4-1BB, and two transcription factors critical to effective and durable T cell immune responses, T-bet and Eomesodermin (Eomes), we will identify T cell molecules and signaling pathways representing promising future targets in cancer immunotherapy.
Our prior work has described the functions of T-bet and Eomes in determining T cell behavior in immune responses. Our preliminary data show that Eomes is essential to cancer immunotherapeutic approaches targeting either PD-1 or 4-1BB on T cells. In the proposed project we will determine how Eomes contributes to T cell anti-tumor activity and determine what, if anything, is needed in T cells beyond Eomes to enact a strong and durable anti-cancer response. The Alliance for Cancer Gene Therapy funded research will provide new insights into the mechanisms of cellular cancer immuno-modulatory therapy that we will use to design and test novel cancer immunotherapeutic approaches.
