A RIPK1-specific PROTAC degrader achieves potent antitumor activity by enhancing immunogenic cell death
Tumor cells frequently hijack RIPK1’s scaffolding function to resist cell death and avoid immune detection. Mannion et al. describe the development of a RIPK1-selective PROTAC degrader that boosts the...

A cGAS-mediated mechanism in naked mole-rats potentiates DNA repair and delays aging
Efficient DNA repair might make possible the longevity of naked mole-rats. However, whether they have distinctive mechanisms to optimize functions of DNA repair suppressors is unclear. We find that na...

The loss of TBK1, or both TBK1 and the related kinase IKKε, results in uncontrolled cell death–driven inflammation. We show that TBK1/IKKε prevent premature cell death by limiting the activity of multiple death pathways in myeloid cells. www.science.org/doi/10.1126/...
