Macrophage polarization is critically involved in inflammation; however, the role of cGAS in macrophage polarization during inflammation remains unclear. In this study, we demonstrated that cGAS was upregulated in the LPS-induced inflammatory response via the TLR4 pathway, and cGAS signaling was activated by mitochondria DNA in macrophages isolated from C57BL\/6J mice. We further demonstrated that cGAS mediated inflammation by acting as a macrophage polarization switch, which promoted peritoneal macrophages and the bone marrow\u2013derived macrophages to the inflammatory phenotype (M1) via the mitochondrial DNA\u2013mTORC1 pathway. In vivo studies verified that deletion of Cgas alleviated sepsis-induced acute lung injury by promoting macrophages to shift from the M1 phenotype to the M2 phenotype. In conclusion, our study demonstrated that cGAS mediated inflammation by regulating macrophage polarization through the mTORC1 pathway, and it further provided a potential therapeutic strategy for inflammatory diseases, especially sepsis-induced acute lung injury.<\/jats:p>","DOI":"10.4049\/jimmunol.2200351","type":"journal-article","created":{"date-parts":[[2023,3,7]],"date-time":"2023-03-07T17:17:28Z","timestamp":1678209448000},"page":"1098-1107","source":"Crossref","is-referenced-by-count":40,"title":["cGAS
