Brain tumors and therapies

We are committed to developing immunotherapies for brain tumors that are effective and selective. We use mice as experimental subjects because much is know about their immune system, and the murine system closely parallels the human immune system. When properly activated, the immune system has the characteristics of an ideal therapy: potent, precise killing of altered cells. But there is much to be learned about how to activate, direct, and control the immune response, particularly against tumors within the brain. We focus mostly on T cell mediated immune responses, and collaborate with investigators in microbiology, materials science, and engineering. Our recent work focuses on using oncolytic viruses to deliver genes expressing cytokines that strengthen the immune response locally within the tumor.
