Results: Inhibition of CaMKII, TAK1, or JNK specifically suppressed lysosome rupture-induced NLRP3 inflammasome activation.

Background: The mechanisms underlying lysosome rupture-mediated inflammasome activation are not understood.

Conclusion: Activation of the Ca2+-CaMKII-TAK1-JNK pathway in lysosome rupture is necessary for complete activation of the NLRP3 inflammasome.

Significance: Our results suggest novel roles for the Ca2+-CaMKII-TAK1-JNK pathway in the regulation of the inflammasome and propose potential therapeutic targets for inflammatory diseases.
