Progress towards identifying immunotherapy targets for IDH1-mutant low grade glioma

Identification of CRKII, CFL1, CNTN1, NME2, and TKT as Novel and Frequent T-cell Targets in Human IDH-Mutant Glioma
click here for abstract.

"By analyzing the repertoire of T-cell target antigens in IDH mut glioma patients, we identified five novel immunogenic TAAs [tumor associated antigens] and confirmed their expression on IDH mut tumors and GSCs [glioma stem cells]."

  1. Don't know where else to post this:

    Suppression of antitumor T cell immunity by the oncometabolite (R)-2-hydroxyglutarate

    Sci-Hub link (working at the moment):

    Another evidence that IDH1 mutation is immunosuppresive. In discussion, the authors write: "Moreover, clinical studies applying checkpoint
    blockade or specific immune interventions such as IDH1R132H-
    specific vaccines may be more effective when combined with IDH
    inhibitors."

    I hope there will be some trials combining IDH1 inhibitors and immunotherapy in near future.

    1. Me too, I've been waiting for such trials for over a year, since this was published:

    2. Here's another one:

      The oncometabolite D-2-hydroxyglutarate is an intercellular mediator in IDH-mutant gliomas that inhibits both complement and T cells
