Title

Peripheral and central kynurenine pathway abnormalities in major depression

Overall design

In this study, a broad, multi-level assessment of abnormalities in the kynurenine pathway in the periphery as well as the CNS was conducted in a general, non-subtyped major depressive disorder (MDD). Kynurenine pathway-metabolites were measured levels in both plasma and cerebrospinal fluid (CSF) of depressed patients (MDD group, n = 63) and healthy controls (control group, n = 48).
