Microbes or danger signals trigger inflammasome sensors, which induce polymerization of the adapter ASC and assembly of an ASC speck. ASC specks recruit and activate caspase-1, which induces IL-1β cytokine maturation and pyroptotic cell death. Here we show that after pyroptosis ASC specks accumulate in the extracellular space, where they promote further IL-1β maturation. In addition, phagocytosis of ASC specks induces lysosomal damage, nucleation of soluble ASC as well as caspase-1 and IL-1β activation in the recipient cell. ASC specks appear in bodily fluids from inflamed tissues and autoantibodies against ASC specks develop in patients and animals with autoimmune pathologies. Together, these findings reveal extracellular functions of ASC specks and a novel form of cell-to-cell communication.
