Peripheral tryptophan and serotonin and kynurenine pathways in major depression: A case-control study

European Psychiatry, 2021
Introduction The tryptophan pathway along with its two branches of metabolism to serotonin and kynurenine seems to be affected in major depression.

Immunometabolic Network Interactions of the Kynurenine Pathway in Cutaneous Malignant Melanoma

Frontiers in Oncology, 2020
Dysregulation of the kynurenine pathway has been regarded as a mechanism of tumor immune escape by the enzymatic activity of indoleamine 2, 3 dioxygenase and kynurenine production. However, the immune-modulatory properties of other kynurenine metabolites

Kynurenine pathway metabolites and suicidality

Neuropharmacology, 2017
Suicide is a major global problem, claiming more than 800,000 lives annually. The neurobiological changes that underlie suicidal ideation and behavior are not fully understood. Suicidal patients have been shown to display elevated levels of inflammation both in the central nervous system and the peripheral blood.

Kynurenine pathway and human systems

Experimental Gerontology, 2020
The essential amino acid L-tryptophan (Trp) appears to play an important role in aging by acting as a general regulator of protein homeostasis. The major route of Trp degradation, the kynurenine pathway (KP), produces a range of biologically active metabolites that can impact or be impacted by a variety of body systems, including the endocrine ...

Immunohistochemical Studies of the Kynurenine Pathway in Morphea [PDF]

International Journal of Tryptophan Research, 2013
Cutaneous sclerosis, resembling that seen in subcutaneous morphea, is a feature of eosinophilic fasciitis and eosinophilia-myalgia syndrome, two conditions in which the kynurenine pathway is known to be activated. To investigate the possibility of activation of the kynurenine pathway in morphea, skin biopsies were taken from involved and non-involved ...

Stimulatory effect of repeated treatment with lipopolysaccharide on a key enzyme of the kynurenine pathway in both genders in rats

European Pharmaceutical Journal, 2016
The neuroprotective or neurotoxic effects of the products of the kynurenine pathway of tryptophan metabolism highly depend on the action of kynurenine-3-monooxygenase (KMO).

Brain Versus Blood: A Systematic Review on the Concordance Between Peripheral and Central Kynurenine Pathway Measures in Psychiatric Disorders

Frontiers in Immunology, 2021
ObjectiveDisturbances in the kynurenine pathway have been implicated in the pathophysiology of psychotic and mood disorders, as well as several other psychiatric illnesses.

Evaluation of the effect of carnosine, its novel derivative trolox-carnosine and trolox in a pre-clinical study focussing on the regulation of immunity

European Pharmaceutical Journal, 2016
The neuroprotective or neurotoxic effects of the products of the kynurenine pathway of tryptophan metabolism highly depend on the action of kynurenine-3-monooxygenase (KMO).

Acute Psychological Stress Modulates the Expression of Enzymes Involved in the Kynurenine Pathway throughout Corticolimbic Circuits in Adult Male Rats

Neural Plasticity, 2016
Tryptophan is an essential dietary amino acid that is necessary for protein synthesis, but also serves as the precursor for serotonin. However, in addition to these biological functions, tryptophan also serves as a precursor for the kynurenine pathway ...
