Research paper on the effect of electro- acupuncture on dopamine release

A technical research paper written by Torres-Rosas et al shows how the stimulation of the sciatic nerve with electro acupuncture can increase the release of dopamine, which in turn controls inflammation in infectious and inflammatory disorders.
Here is the abstract. 
Previous anti-inflammatory strategies against sepsis, a
leading cause of death in hospitals, had limited efficacy in clinical trials, in part because they targeted single cytokines and the experimental models failed to mimic clinical settings1–3. Neuronal networks represent physiological mechanisms, selected by evolution to control inflammation, that can be exploited for the treatment of inflammatory
and infectious disorders3. Here, we report that sciatic
nerve activation with electroacupuncture controls systemic inflammation and rescues mice from polymicrobial peritonitis. Electroacupuncture at the sciatic nerve controls systemic inflammation by inducing vagal activation of aromatic
l-amino acid decarboxylase, leading to the production of dopamine in the adrenal medulla. Experimental models with adrenolectomized mice mimic clinical adrenal insufficiency4, increase the susceptibility to sepsis and prevent the anti-inflammatory effects of electroacupuncture. Dopamine inhibits cytokine production via dopamine type 1
(D1) receptors. D1 receptor agonists suppress systemic inflammation and rescue mice with adrenal insufficiency
from polymicrobial peritonitis. Our results suggest a new anti-inflammatory mechanism mediated by the sciatic and vagus nerves that modulates the production of catecholamines in the adrenal glands. From a pharmacological perspective, the effects of selective dopamine agonists mimic the anti-inflammatory effects of electroacupuncture and can provide therapeutic advantages to control inflammation in infectious and inflammatory disorders.
