  eLife Assessment

  This important study addresses the timely and interesting question of how itaconate generation emerged in evolution, using taxonomic analysis of the gene and enzyme cis-aconitate decarboxylase (CAD). The authors provide solid evidence identifying three CAD branches in metazoans and showing that the early metazoan paleo-form indeed generates aconitate and is already linked to innate immunity. They further provide limited evidence suggesting that taxonomic differences in subcellular localisation of this enzyme may allow for innate immune signalling without compromising cellular energetics. The implications of the study will be of high interest to the field of innate host defence and immunometabolism.
