Our laboratory's research interests focus on cell therapy with cytotoxic T cells (CTL) for viral and malignant diseases. Led by Catherine Bollard, MD, we are running clinical trials assessing the safety of adoptively transferred donor-derived virus-specific CTL for the prevention and treatment of viral infection after allogeneic stem cell and cord blood transplant. In addition, we are investigating the utility of this approach using genetically modified virus-specific CTL for the prevention and treatment of viral infection and relapse after transplant. We also are evaluating the efficacy of tumor-specific CTL in patients with relapsed EBV-positive Hodgkin’s disease and non-Hodgkin Lymphoma. Further, we are interested in novel strategies to target the cancer stem cell in lymphoma and to counteract tumor immune evasion mechanisms to enhance the efficacy of adoptive immunotherapy protocols. We are also exploring the feasibility of expanding T cells targeting non-EBV tumor-associated antigens to treat EBV-negative lymphomas and leukemias as well as HIV.
Dr. Bollard is also the Director of the Program for Emerging Technologies in Immune Cell Therapies.
