abstract = {Gliomas with mutations in the gene for isocitrate
dehydrogenase (IDH) display a unique immune microenvironment
that is distinct from IDH-wildtype gliomas. This unique
immune microenvironment is shaped by 2-hydroxyglutarate
(2-HG), an oncometabolite produced by mutant IDH. These
features provide an opportunity to develop and test targeted
immunotherapies for IDH-mutant gliomas.IDH-mutant gliomas
are characterized by an immunosuppressive tumor immune
microenvironment (TIME) that suppresses the infiltration and
activation of tumor-specific T cells. This is owed both to
direct effects of the oncometabolite 2-hydroxyglutarate on
glioma-infiltrating T cells and myeloid cells and indirect
effects on the chemotactic profile of tumor cells. These
immunosuppressive effects are reversed by IDH inhibitors
recently approved for the treatments of IDH-mutant gliomas.
At the same time, clinical trials have demonstrated
encouraging results for targeted immunotherapies using
vaccines targeting the most frequent mutation IDH1R132H.The
reversal of the immunosuppressive effects by IDH inhibitors
has opened exciting avenues for combinatorial
immunotherapies such as vaccines and immune checkpoint
inhibitors.},
