Title | The lysosome rupture-activated TAK1-JNK pathway regulates NLRP3 inflammasome activation. |
Journal | J Biol Chem |
Abstract |
Lysosome rupture triggers NLRP3 inflammasome activation in macrophages. However, the underlying mechanism is not fully understood. Here we showed that the TAK1-JNK pathway, a MAPK signaling pathway, is activated through lysosome rupture and that this activation is necessary for the complete activation of the NLRP3 inflammasome through the oligomerization of an adapter protein, apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC). We also revealed that the activation of the TAK1-JNK pathway is sustained through Ca(2+) ions and that calcium/calmodulin-dependent protein kinase type II functions upstream of the TAK1-JNK pathway and specifically regulates lysosome rupture-induced NLRP3 inflammasome activation. These data suggest a novel role for the TAK1-JNK pathway as a critical regulator of NLRP3 inflammasome activation. |
