Our laboratory's research focuses on generating durable memory T cell responses to cancer. What is known about generating immunological memory has historically derived from studies of infectious pathogens. Because tumors are an altered form of self-tissue, memory T cell responses to tumors have been characteristically difficult to generate, and mechanisms for their maintenance have not been well understood. Our laboratory has established that autoimmune disease is a critical determinant for the maintenance of T cell memory to tumor antigens. Over the past decade, we have found that autoimmune melanocyte destruction (known as vitiligo) is required to maintain protective T cell responses against melanoma. Our recent work shows that the most functional tumor-specific memory T cells reside in peripheral tissues, establishing that tissue-resident memory (TRM) cells are a critical component of long-lived immunity to cancer.
Oncogenic pathways are the fundamental basis for cancer, and our laboratory also studies the link between oncogenic signaling and host anti-tumor immunity. Our studies indicate that oncogenic BRAF signaling in melanoma cells promotes their ability to recruit and support immunosuppressive myeloid cells and regulatory T cels within the tumor microenvironment. We have demonstrated how inhibitor drugs that target BRAF can be optimally combined with immunotherapies that perturb immunosuppressive cells in tumors.
