Zusammenfassung der Projektergebnisse

Our results show that IDH mutation associated D-2-HG secretion triggers paracrine effects resulting in a block of differentiation and activation of DCs in the tumor environment. Interestingly, not only the classical oncometabolute D-2-HG but also its enantiomer L-2-HG had immunomodulatory potential and reprogrammed DC metabolism and function. Furthermore our data suggest that abundantly produced D-2HG in tumors that harbor IDH mutations such as AML and glioma may act as a novel immunometabolic modulator of T cells. The T-cells’ bioenergetics are shifted towards oxidative phosphorylation and interference with the stability of the pro-glycolytic HIF-1α diminishes the formation of pro-inflammatory Th17 cells and favors the abundance of Tregs.
