Cyclic dipeptides (CDPs) are a group of hormone-like molecules that are evolutionarily conserved from bacteria to humans. In bacteria, CDPs are used in quorum sensing (QS) to communicate information about population size and to regulate a behavioural switch from symbiosis with their host to virulence. In mammals, CDPs have been shown to act on glial cells (macrophage-like cells) to control a conceptually homologous behavioural switch between homeostatic and inflammatory modes, with implications for the control of neuro-degenerative disease. Here we argue that, because of their capacity to regulate inflammation via glial cells and induce a protective response in neuronal cells, CDPs have potential therapeutic utility in an array of inflammatory diseases.
