Study TitleMetabolomic analysis to assess response to immunotherapy for malignant brain tumors: Part 2
Study TypeCancer surrogate biomarker discovery
Study SummaryAn effective immune response in patients with cancer treated with immunotherapy includes dendritic cell (DC) activation and migration followed by stimulation of CD8 and CD4 T cells. This then leads to the activation, proliferation and further activation of other immune cell populations including NK cells or immunosuppressive populations such as Tregs and myeloid derived suppressor cells (MDSCs). These studies were carried out utilizing murine brain tumor models treated with an RNA DC vaccine platform. We hypothesized that metabolomic analyses of urines would be sensitive to the action of this diverse set of immune cells. The objective of this study was to evaluate the feasibility of using metabolomics to follow immune responses after immunotherapy. We chose NMR as our analytical technique of choice, as it has many favorable qualities that make it ideal for analyses of urine.
