Macrophages engage in a sequence of dynamic functional changes during immune responses. Here the authors elucidate a two-stage remodelling of the tricarboxylic acid cycle during this process, which is driven by regulation of the pyruvate dehydrogenase and the oxoglutarate dehydrogenase complexes, and causes transient accumulation of immunoregulatory metabolites.
