A novel mechanism of autophagy-dependent immunosuppression in cancer?

Autophagy underlies several immunosuppressive mechanisms that collectively endow cancer cells with prominent immunoevasive features. Recent data from Hoslett et al. demonstrate that a specialized variant of autophagy commonly known as nucleophagy actively removes PARP1 molecules trapped on DNA upon pharmacological inhibition, mediating robust cytoprotective and possibly immunosuppressive effects.
