Quinolinic acid (QUIN), an excitotoxic tryptophan metabolite, has been identified and measured in human cerebrospinal fluid (CSF) using a mass-fragmentographic method. Furthermore, its content has been evaluated in frontal cortex obtained at autopsy from the cadavers of patients who died
Katherine R Leaver et al.
ACS chemical neuroscience, 3(2), 114-119 (2012-08-04)
There is evidence that excitotoxicity and prolonged microglial activation are involved in neuronal death in neurodegenerative disorders. Activated microglia express various molecules, including the translocator protein 18 kDa (TSPO; formerly known as the peripheral benzodiazepine receptor) on the outer mitochondrial

A retrospective study of 261 Vietnamese adults with severe malaria was conducted to determine the relationship between cerebrospinal fluid (CSF) levels of metabolites of the kynurenine pathway, the incidence of neurologic complications, and the disease outcome. Three metabolites were measured:

The kynurenine pathway (KP) is a major route of L-tryptophan catabolism leading to production of several neurobiologically active molecules. Among them is the excitotoxin quinolinic acid (QUIN) that is known to be involved in the pathogenesis of several major inflammatory

The FEBS journal, 279(8), 1356-1365 (2012-01-18)
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
