Within the brain, quinolinic acid is only produced by activated microglia and macrophages . 1 By overactivating NMDA receptors, quinolinic acid produces neurotoxicity, which has been implicated in certain neurodegenerative disorders. 2 Quinolinic acid can also generate reactive oxygen species, has immunomodulatory actions, and promotes the.
Over the last two decades, evidence for the involvement of quinolinic acid (QUIN) in neuroinflammatory diseases has been exponentially increasing. Within the brain, QUIN is produced and released by infiltrating macrophages and activated microglia, the very cells that are prominent. Quinolinic acid: a pathogen in seizure disorders? Schwarcz R, Speciale C, Okuno E, French ED, Köhler C. The evidence for an involvement of QUIN in human seizure disorders is clearly circumstantial. Importantly, QUIN is not a classical neurotransmitter and may thus play only a negligible or no role at all in normal brain function (Foster et al., 1984). We have yet to understand if and how such. Homoquinolinic acid (HQA) is a potent excitotoxin which is a conformationally-restricted analogue of N-methyl-D-aspartate (NMDA) and a partial agonist of the main/glutamate site of the NMDA receptor, with some selectivity for NR2B subunit-containing receptors. It is approximately equipotent to NMDA and about five times more potent than quinolinic acid as an agonist of the NMDA receptor Datei:Quinolinic Acid.svg. aus Wikipedia, der freien Enzyklopädie.

It is part of an intermediate step in the production of NAD from tryptophan, and is a precursor to the production of nicotine. Like many other intermediates in the kynurenine pathway, it can act as a neurotransmitter. QA is toxic, primarily via its ability to keep the NMDA receptor active (excitotoxicity), and also due.

Quinolinic acid is a byproduct of the kynurenine pathway, which is responsible for catabolism of tryptophan in mammals.This pathway is important for its production of the coenzyme nicotinamide adenine dinucleotide (NAD+) and produces several neuroactive intermediates including quinolinic acid, kynurenine (KYN), kynurenic acid (KYNA), 3-hydroxykynurenine (3-HK), and 3-hydroxyanthranilic acid (3. Quinolinic acid and NMDA were injected at a dose of 120 nmols, a dose found in preliminary work to induce a sub-maximal destruction of pyramidal neurones while melatonin, deprenyl and nialamide were co-administered at two dose levels by mixing solutions of the individual agents in the appropriate proportions.

Quinolinic acid (QA), a biologically potent but neurodestructive metabolite is catabolized by quinolinic acid phosphoribosyltransferase (QPRT) in the first step of the de novo NAD(+) biosynthesis pathway. This puts QPRT at the junction of two different pathways, that is, de novo NAD(+) biosynthesis and the kynurenine pathway of tryptophan.
