Research Interests

Three-hour time lapse of HER2-specific T cells destroying a brain tumor cell

Dr. Nabil Ahmed is interested in the adoptive cellular immunotherapy for solid tumors. He employs genetically engineered T cells that express tumor-specific chimeric antigen receptors (CARs) to target tumor restricted antigens. CARs are artificial molecules that enable the patient's T cells to be activated upon contact with these tumor antigens. This therapeutic approach has the major advantage of offering specific killing of malignant cells that express a tumor-restricted antigen with minimal bystander effects. In a series of preclinical studies, Dr. Ahmed has shown that HER2-specific T cells from healthy donors and brain tumor patients recognize and kill HER2 positive medulloblastoma and glioblastoma multiforme (GBM) cell lines as well as autologous primary tumors. In addition, adoptive transfer of HER2-specific T cells induced regression of established medulloblastomas and GBM in an orthotopic xenograft models. At present, Dr. Ahmed is studying methods to improve the anti-tumor efficacy, growth and survival of genetically modified HER2-specific T cells in the central nervous system and their ability to home to tumor sites to eradicate loco-regionally advanced disease. In his ongoing work, Dr. Ahmed is focusing on the development of an innovative immunotherapy approach for pediatric bone sarcomas and breast cancer.
