The impact of electroconvulsive therapy on the tryptophan-kynurenine metabolic pathway

Our findings show that ECT influences the TRP-KYN pathway, with a shift in TRP-KYN metabolites balance towards molecules with neuroprotective properties correlating with antidepressant effects of ECT; thereby providing a first line of evidence that the mechanism of action of ECT is (co)mediated by the TRP-KYN pathway.
