Elevated cerebrospinal fluid quinolinic acid levels are associated with region-specific cerebral volume loss in HIV infection [PDF]

, 2001
Neuronal injury, dendritic loss and brain atrophy are frequent complications of infection with human immunodeficiency virus (HIV) type 1. Activated brain macrophages and microglia can release quinolinic acid, a neurotoxin and NMDA (N-methyl-D-aspartate ...

Altered Cerebrospinal Fluid Tryptophan–Kynurenine Pathway Metabolism in Multiple System Atrophy

Movement Disorders, EarlyView.
Abstract Background Alterations in tryptophan–kynurenine (TRP‐KYN) metabolism, which is associated with neuroinflammation, remain unclear in multiple system atrophy (MSA). Objective The aim was to investigate cerebrospinal fluid (CSF) TRP metabolites in MSA and their associations with other biomarkers.

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 ...

Repurposing antimicrobial agents for neuroprotection: Mechanisms, clinical potential, and challenges

Neuroprotection, EarlyView.
Antimicrobial agents exert neuroprotective effects through modulation of interconnected pathways. Tetracyclines, macrolides, antimalarial agents, sulfones, and antiparasitic agents suppress neuroinflammation, oxidative stress, and apoptosis while preserving mitochondrial function and neurotransmission.

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 ...

Kaempferol Protects Intestinal Health in Chinese Forest Musk Deer Possibly by Regulating Intestinal Microbiota and Inhibiting the NF‐κB/NLRP3 Signaling Pathway

Integrative Zoology, EarlyView.
Kaempferol modulates the tryptophan metabolism pathway by increasing the abundances of Christensenellaceae R7 group, Bacteroides, and Blautia and reducing that of Rikenellaceae RC9 gut group, thereby significantly increasing the levels of ILA and IAA. This process inhibits the activation of NF‐κB/NLRP3 signaling pathway, reduces pro‐inflammatory factor
