Two cGAS-like receptors induce antiviral immunity in Drosophila

Abstract excerpt

In mammals, cyclic GMP–AMP (cGAMP) synthase (cGAS) produces the cyclic dinucleotide 2′3′-cGAMP in response to cytosolic DNA and this triggers an antiviral immune response. cGAS belongs to a large family of cGAS/DncV-like nucleotidyltransferases that is present in both prokaryotes1 and eukaryotes2–5. In bacteria, these enzymes synthesize a range of cyclic oligonucleotides and have recently emerged as important...
