Silica particles induce intereukin-1 (IL-1) response to contribute to lung inflammation, but the underlying mechanism is unclear. Here the authors show that silica induces cell death and release of mitochondria and genomic DNA, which are sensed by STING with or without involving cGAS, respectively, for IL-1 induction and lung inflammation.
