Peripheral and central levels of kynurenic acid in bipolar disorder subjects and healthy controls

Translational Psychiatry, 2019
Metabolites of the kynurenine pathway of tryptophan degradation, in particular, the N-Methyl-d-aspartic acid receptor antagonist kynurenic acid (KYNA), are increasingly recognized as primary pathophysiological promoters in several psychiatric diseases ...

Control of action potential afterdepolarizations in the inferior olive by inactivating A‐type currents through KV4 channels

The Journal of Physiology, EarlyView.
Abstract figure legend KV4 channel availability regulates inferior olive action potential duration. The durations of action potentials in inferior olive neurons (blue) depend strongly on preceding membrane potential, with afterdepolarizations varying over the physiological range by almost two orders of magnitude (open circles). Voltage clamp recordings

The Metabolic Factor Kynurenic Acid of Kynurenine Pathway Predicts Major Depressive Disorder

Frontiers in Psychiatry, 2018
Background: Metabolic factors in the kynurenine pathway (KP) have been widely accepted as being a major mechanism in Major Depressive Disorder (MDD). However, the effects of these metabolites on the degree and pattern of MDD are still poorly understood ...

Exhaustive exercise abolishes REV‐ERB‐α circadian rhythm and shifts the kynurenine pathway to a neurotoxic profile in mice

The Journal of Physiology, EarlyView.
Abstract figure legend Acute exhaustive exercise (EE) reduces REV‐ERB‐α protein levels in skeletal muscle, which impairs its transcriptional repression of kynurenine (KYN) 3‐monooxygenase (KMO), a key enzyme in the KYN pathway that converts KYN into potentially neurotoxic metabolites, collectively referred to as ‘kynurenines’. This study identifies KMO

Plasma neurofilament light chain and amyloid-β are associated with the kynurenine pathway metabolites in preclinical Alzheimer’s disease

Journal of Neuroinflammation, 2019
Background Blood markers indicative of neurodegeneration (neurofilament light chain; NFL), Alzheimer’s disease amyloid pathology (amyloid-β; Aβ), and neuroinflammation (kynurenine pathway; KP metabolites) have been investigated independently in ...

Untargeted metabolomics of colonic digests reveals kynurenine pathway metabolites, dityrosine and 3-dehydroxycarnitine as red versus white meat discriminating metabolites [PDF]

, 2016
Epidemiological research has demonstrated that the consumption of red meat is an important risk factor for the development of colorectal cancer (CRC), diabetes mellitus and cardiovascular diseases.

The Synthesis of Kynurenic Acid in Mammals: An Updated Kynurenine Aminotransferase Structural KATalogue

Frontiers in Molecular Biosciences, 2019
Kynurenic acid (KYNA) is a bioactive compound that is produced along the kynurenine pathway (KP) during tryptophan degradation. In a few decades, KYNA shifted from being regarded a poorly characterized by-product of the KP to being considered a main ...

Aetiopathogenesis of infantile epileptic spasms syndrome and mechanisms of action of adrenocorticotrophin hormone/corticosteroids in children: A scoping review

Developmental Medicine &Child Neurology, Volume 67, Issue 8, Page 1004-1025, August 2025.
Why does infantile epileptic spasms syndrome (IESS) occur with a variety of underlying conditions and why does it respond to adrenocorticotrophin hormone (ACTH)/corticosteroids? Our scoping review summarizes five hypotheses from the literature: gene/epigenetic regulation, stress/HPA axis activation, neuroinflammation/immune function, altered neuronal ...

Psychosocial stress and inflammation driving tryptophan breakdown in children and adolescents : a cross-sectional analysis of two cohorts [PDF]

, 2018
Background: Tryptophan breakdown is an important mechanism in several diseases e.g. inflammation and stress induced inflammation have been associated with the development of depression via enhanced tryptophan breakdown.
