Approximately 20 years ago it was discovered that the vagus nerve regulates pro-inflammatory cytokine levels and inflammation. Subsequent research using several preclinical models revealed that vagus nerve stimulation evokes a protective decrease in pro-inflammatory cytokines in multiple inflammatory disorders. Consequently, the pro- and anti- inflammatory cytokine balance has become the predominant readout for indicating a positive outcome of vagus nerve stimulation. However, cytokine levels are just a single aspect of an effective immune response. It is conceivable that vagus nerve stimulation regulates inflammation through additional mechanisms. In this letter, I discuss a manuscript that describes how vagus nerve stimulation promotes resolution of inflammation via regulating the balance of specialised pro-resolving mediator levels and neutrophil activity.
