IDH1 Inhibition Reawakens the Immune Response against Cholangiocarcinoma

Abstract:
Isocitrate dehydrogenase 1 mutations (mIDH1) are common in cholangiocarcinoma, but their exact mechanisms in cholangiocarcinoma initiation and maintenance are unclear. In this issue of Cancer Discovery, Wu and colleagues identify immune suppression via TET2 inactivation as the primary means by which mIDH1 maintains cholangiocarcinoma survival, leading to an efficacious new combination of mIDH1 inhibitors and immune checkpoint blockade targeting regulatory T cells. See related article by Wu et al., p. 812 (9).
