Smac mimetics synergize with immune checkpoint inhibitors to promote tumour immunity against glioblastoma

Smac mimetics sensitize cancer cells to the extrinsic cell death pathway and stimulate anti-tumour immunity. In this study, the authors show that Smac mimetics can synergize with immune checkpoint inhibitors to control tumour growth in mouse cancer models, including aggressive CNS tumours, in a cytotoxic CD8+T-cell- and TNFα-dependent manner.
