Determining factors necessary for memory T cell responses to optimize immunotherapy.
Our work determines the factors necessary for long-term survival of T cells to maintain their protective activity against both tumors and virus infections. While there is typically a large expansion of T cells early during an immune response, only a minority of these cells have the ability to survive long-term in the host. This prolonged survival is necessary for providing sustained protection against re-infection or recurrence of tumors. In fact, a major positive prognostic indicator for adoptive T cell therapies targeting cancer is the length of time that these T cells are sustained in the patient.
Our laboratory uses a variety of cutting-edge molecular techniques coupled with in vivo and in vitro models to understand the fundamental programming of memory T cell responses. These range from manipulation of transcriptional regulation, cell-extrinsic signaling and gene editing to metabolic reprogramming of T cells. We then devise methods to exploit this knowledge to design T cells that can better survive in the hostile environment of a tumor and enhance anti-tumor activity.
