anti-HER2-CAR autologous CMV-specific cytotoxic T lymphocytes

Autologous human cytomegalovirus (CMV)-specific human cytotoxic T lymphocytes (CTLs) transduced with a retroviral vector encoding a human anti-HER2 (epidermal growth factor receptor 2) chimeric T cell receptor (CAR) gene with potential immunostimulatory and antineoplastic activities. Autologous CTLs from a patient with HER2- and CMV-positive glioblastoma multiforme (GBM) are genetically modified to express CAR gene specific for HER2 on their cell surfaces. After expansion in culture and reintroduction into the patient, the anti-HER2-CAR autologous CMV-specific CTLs bind to HER2 antigen on tumor cell surfaces; subsequently, HER2-positive tumor cells and stem cells may be lysed. HER2 (ErbB2), a receptor tyrosine kinase (RTK) overexpressed by a variety of cancer cell types, plays key roles in tumor cell proliferation and tumor angiogenesis. CMV is present in the majority of GBM tumors. Check for active clinical trials using this agent. (NCI Thesaurus)
