Mitochondrial control of IFNγ signaling

VDAC2 enforces a mitochondrial checkpoint to cancer immunity

Mitochondrial integrity controls cellular and immunological homeostasis in various pathophysiological settings. Recent findings suggest that VDAC2 antagonizes the ability of IFNγ to drive mitochondrial permeabilization in malignant cells by inhibiting BAK, thus promoting cell survival and immunoevasion.
