Distress Intolerance, Kynurenic Acid, and Schizophrenia [PDF]

JAMA Psychiatry, 2014
We are all intuitively aware that when we are under stress, we think differently and often less well than when we are calmer. The study by Chiapelli et al1 in this issue of the journal addresses some of the critical links underlying the effects of stress on cognition.

Kynurenic Acid and Kynurenine Aminotransferase in Heart [PDF]

Pediatric Research, 1997
Kynurenic acid (KYNA) is a tryptophan metabolite and represents the only known endogenous compound acting as an antagonist to excitatory amino acid receptors in the mammalian CNS. Blocking of these receptors in CNS by KYNA affects cardiac function.

Changes in synaptic transmission and protein expression in the brains of adult offspring after prenatal inhibition of the kynurenine pathway [PDF]

, 2013
During early brain development, N-methyl-d-aspartate (NMDA) receptors are involved in cell migration, neuritogenesis, axon guidance and synapse formation, but the mechanisms which regulate NMDA receptor density and function remain unclear. The kynurenine

Potato- An Important Source of Nutritional Kynurenic Acid [PDF]

Plant Foods for Human Nutrition, 2012
Kynurenic acid (KYNA) is a metabolite of tryptophan which is formed along the kynurenine pathway. KYNA may possess neuroprotective, anti-inflammatory, antioxidant and antiproliferative properties. This study measured the concentration of KYNA in various varieties of potatoes and products made from potatoes.

Circulating amino acids and amino acid-related metabolites and risk of breast cancer among predominantly premenopausal women

npj Breast Cancer, 2021
Known modifiable risk factors account for a small fraction of premenopausal breast cancers. We investigated associations between pre-diagnostic circulating amino acid and amino acid-related metabolites (N = 207) and risk of breast cancer among ...

Differential Levels of Tryptophan–Kynurenine Pathway Metabolites in the Hippocampus, Anterior Temporal Lobe, and Neocortex in an Animal Model of Temporal Lobe Epilepsy

Cells, 2022
Glutamate-receptor-mediated hyperexcitability contributes to seizure generation in temporal lobe epilepsy (TLE). Tryptophan–kynurenine pathway (TKP) metabolites regulate glutamate receptor activity under physiological conditions.

Fathoming the kynurenine pathway in migraine: why understanding the enzymatic cascades is still critically important [PDF]

, 2015
Kynurenine pathway, the quantitatively main branch of tryptophan metabolism, has been long been considered a source of nicotinamide adenine dinucleotide, although several of its products, the so-called kynurenines, are endowed with the capacity to ...
