The parasympathetic nervous system, through the vagus nerve, can down-regulate inflammation in vivo by decreasing the release of cytokines, including tumor necrosis factor alpha (TNFalpha), by activated macrophages. The vagus nerve may exert antiinflammatory actions via a specific effect of its principal neurotransmitter, acetylcholine, on the alpha7 subunit of nicotinic acetylcholine receptors (alpha7nAChR) on macrophages. The present study was undertaken to obtain insight into the role of the cholinergic antiinflammatory pathway in arthritis.
