      Evaluation Summary:

      The authors addressed the role of a STING ortholog in antimicrobial defense of choanoflagellates. The analysis of the response of the choanoflagellate Monosiga brevicollis to a variety of bacterial species revealed that exposure of M. brevicollis to Pseudomonas aeruginosa conditioned medium results in choanoflagellate death and the authors found that this is dependent on the newly discovered ortholog of STING. Characterization reveals that the STING response can be induced by 2'3' cGAMP, which parallels the activation of STING in diverse species. In addition, the finding that cyclic dinucleotide treatment induces autophagy also has parallels with the effector pathways observed in other organisms. There are a number of strengths as outlined by the Reviewers. First, the development of a Choanaoflagellate model system to study innate immunity, second with the development of genetics for M. brevicollis, third, the demonstration of a functional STING system in one of the closest relatives to animals and fourth, that cell death occurs in response to cyclic dinucleotides.
