Key Takeaway
Landmark paper establishing that vagus nerve stimulation can inhibit systemic inflammation through the "cholinergic anti-inflammatory pathway."
Summary
This seminal Nature review describes the discovery and mechanisms of the inflammatory reflex - a neural circuit through which the vagus nerve regulates immune responses.
Vagal stimulation releases acetylcholine, which binds to receptors on immune cells and inhibits the release of pro-inflammatory cytokines like TNF, IL-1, and IL-6.
