Activators may cause relocalization to endosomal or Golgi compartments. The distinct changes in endosomal composition lead to the activation of the NLRP3 inflammasome. The activation of the NLRP3 inflammasome is mediated by PtdIns4P on the dispersed trans-Golgi network. The activation of NLRP3 and pyrin inflammasomes is mediated by Histone deacetylase 6 (HDAC6) through a mechanism similar to an aggresome.
