Using immunology and genomics tools, we study how the immune response to brain tumors happens. We use established preclinical models, new preclinical models we have developed, and patient-derived tissue and cells to address what T cells recognize and how antigen is presented. These studies are complemented by clinical trial efforts. Our ultimate goal is to better understand the diseases of our patients in order to develop improved therapies... Methods We employed single-cell PCR to isolate a TCR specific for the Imp3 D81N neoantigen (mImp3) previously identified within the murine glioblastoma model GL261. This TCR was used to generate the Mutant Imp3-Specific TCR TransgenIC (MISTIC) mouse in which all CD8 T cells are specific for mImp3. The therapeutic efficacy of neoantigen-specific T cells was assessed through a model of cellular therapy consisting of the transfer of activated MISTIC T cells and interleukin 2 into lymphodepleted tumor-bearing mice. We employed flow cytometry,..
