TWiN discusses research showing that sciatic nerve activation with electroacupuncture at the sciatic nerve controls systemic inflammation and rescues mice from polymicrobial peritonitis, by inducing vagal activation of aromatic L-amino acid decarboxylase, leading to the production of dopamine in the adrenal medulla.
TWiN explains the finding that immunity to commensal bacteria promotes sensory neuron regeneration via the cytokine interleukin-17A.
