TAK1ng control: TAK1 restrains NLRP3 activation.

In this issue of JEM, Malireddi et al. (https://doi.org/10.1084/jem.20171922) demonstrate that macrophage-specific loss of TAK1 causes spontaneous NLRP3 inflammasome activation, driven by unregulated TNF secretion and signaling. This has implications for therapeutically targeting TAK1, enhancing its potential function as an anticancer drug treatment.
