Abstract
DNA damage-induced activation of the cytoplasmic DNA sensor cGAS influences the outcome of infections, autoinflammation, and cancer. Recent studies by Harding et al. (2017. Nature. http://dx.doi.org/10.1038/nature23470), Mackenzie et al. (2017. Nature. http://dx.doi.org/10.1038/nature23449), and Bartsch et al. (2017. Human Molecular Genetics. https://doi.org/10.1093/hmg/ddx283) demonstrate a role for micronuclei formation in DNA damage-induced immune activation.
