Regulating innate immunity with dopamine and electroacupuncture

Neural circuits are able to modulate immune responses by detecting inflammatory mediators and relaying signals back to the immune system. Here, in a mouse model of sepsis, the authors show that the immune responses can be modulated by electroacupuncture, which stimulates a neural circuit that results in the release of dopamine. The mechanism, like the inflammatory reflex, is neither sympathetic nor parasympathetic. Their results show a potential way forward in developing therapies for sepsis in dopamine agonists (pages 291–295).
