Coupling DNA sensing to the initiation of immune responses necessitates auxiliary control mechanisms to avoid autoimmunity. A key factor is the exonuclease TREX1, which antagonizes DNA-mediated activation of cGAS. Two studies, by Mohr et al. (2021) and Zhou et al. (2021), uncover new aspects of this important control mechanism.
