Changes in Tryptophan-Kynurenine Metabolism in Patients with Depression Undergoing ECT - A Systematic Review
Aarsland, Tore Ivar Malmei; Instanes, Johanne Telnes; Posserud, Maj-Britt Rocio; Ulvik, Arve; Kessler, Ute; Haavik, Jan (Journal article; Peer reviewed, 2022)The kynurenine pathway of tryptophan (Trp) metabolism generates multiple biologically active metabolites (kynurenines) that have been implicated in neuropsychiatric disorders. It has been suggested that modulation of ... -
The effect of electroconvulsive therapy (ECT) on serum kynurenine pathway metabolites in late-life depression
Aarsland, Tore Ivar Malmei; Haavik, Jan; Ulvik, Arve; Ueland, Per Magne; Dols, Annemiek; Kessler, Ute (Journal article; Peer reviewed, 2023)Background: Depression is reportedly associated with alterations in kynurenine pathway metabolites (kynurenines). Several kynurenines are involved in glutamate signaling, and some have potentially neurotoxic effects while ... -
The effect of electroconvulsive therapy (ECT) on serum tryptophan metabolites
Aarsland, Tore Ivar Malmei; Leskauskaite, Ieva; Midttun, Øivind; Ulvik, Arve; Ueland, Per Magne; Oltedal, Leif; Erchinger, Vera Jane; Ødegaard, Ketil Joachim; Haavik, Jan; Kessler, Ute (Peer reviewed; Journal article, 2019-05-31)Background: Prior studies suggest that activation of the tryptophan catabolism via the kynurenine pathway by proinflammatory cytokines may be involved in the pathophysiology of depression. Electroconvulsive therapy (ECT) ... -
Serum concentrations of kynurenines in adult patients with attention-deficit hyperactivity disorder (ADHD): a case–control study
Aarsland, Tore Ivar Malmei; Landaas, Elisabeth Toverud; Hegvik, Tor-Arne; Ulvik, Arve; Halmøy, Anne; Ueland, Per Magne; Haavik, Jan (Peer reviewed; Journal article, 2015-11-05)Background: The essential amino acid tryptophan is catabolised mainly through the kynurenine pathway. Altered circulating levels of kynurenines have been reported in chronic inflammatory conditions and in several ... -
Tryptophan and kynurenine pathway metabolites in neuropsychiatric disorders
Aarsland, Tore Ivar Malmei (Doctoral thesis, 2024-05-21)Bakgrunn: Kynureninar er ei gruppe metabolittar av den kosthaldsavhengige aminosyra tryptofan (Trp) som er involverte i ei rekkje biologiske mekanismar, mellom anna inflammasjon og reguleringa av nevrotransmitteren glutamat. ...
