Invasion of microbial DNA into the cytoplasm of animal cells triggers a cascade of host immune reactions that help clear the infection; however, self DNA in the cytoplasm can cause autoimmune diseases. Biochemical approaches led to the identification of cyclic GMP-AMP (cGAMP) synthase (cGAS) as a cytosolic DNA sensor that triggers innate immune responses. Here we show that cells from cGAS-deficient (cGas−/−) mice, including fibroblasts, macrophages and dendritic cells, failed to produce type-I interferons and other cytokines in response to DNA transfection or DNA virus infection. cGas−/− mice were more susceptible to lethal infection with herpes simplex virus-1 (HSV1) than wild type mice. We also show that cGAMP is an adjuvant that boosts antigen-specific T cell activation and antibody production in mice.
