Scientific Interests

Dr. Robert Prins' research group studies immune-based therapies for the treatment of malignant glioma. Despite recent advances in traditional treatment options, the prognosis for these patients has not changed appreciably in twenty years. Thus, these patients are left with few treatment options. Members of Prins' research group are attempting to apply what they learn from pre-clinical models towards the implementation of immunotherapy clinical trials for brain tumor patients. This work is truly ÒtranslationalÓ in nature and straddles the boundary between clinical medicine and basic research. On one hand, Prins' group spends a significant amount of time trying to understand the mechanisms by which tumor-specific T-cells can be activated to target tumor cells in the brain. On the other hand, Prins leads the laboratory effort for immunotherapy clinical trials at UCLA in glioma patients; in this aspect, he generates dendritic cell vaccines for these patients. This work represents the Òbench to bedsideÓ philosophy and truly is an active synergy between laboratory and clinical medicine.
