The kynurenine and serotonin pathway, neopterin and biopterin in depressed children and adolescents: an impact of omega-3 fatty acids, and association with markers related to depressive disorder. A randomized, blinded, prospective study

Frontiers in Psychiatry
Depressive disorder is a severe mental condition. In addition to genetic factors, immunological-inflammatory factors, oxidative stress, and disturbances in neurotransmitter metabolism, kynurenine and serotonin pathways may play a role.

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.

Imbalanced Kynurenine Pathway in Schizophrenia

, 2014
Several studies suggest a role for kynurenic acid (KYNA) in the pathophysiology of schizophrenia. It has been proposed that increased brain KYNA levels in schizophrenia result from a pathological shift in the kynurenine pathway toward enhanced KYNA ...

Kynurenines and Glutamate [PDF]

, 2016
Glutamate is firmly established as the major excitatory neurotransmitter in the mammalian brain and is actively involved in most aspects of neurophysiology. Moreover, glutamatergic impairments are associated with a wide variety of dysfunctional states, and both hypo- and hyperfunction of glutamate have been plausibly linked to the pathophysiology of ...

Gut microbiota dysbiosis and Long COVID susceptibility in chronic kidney disease

VIEW, EarlyView.
This study investigated gut microbiota dysbiosis and its association with Long COVID susceptibility in 224 hemodialysis patients. We found that 35.3% of patients developed Long COVID, characterized by neurological symptoms and elevated inflammatory markers, accompanied by significant gut microbiota alterations including enriched proinflammatory taxa ...

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

Lupus Panniculitis Immunoprofiling Reveals a Cytotoxic, Type 1‐Skewed T‐Cell Response With Signs of Metabolic Alteration

Allergy, EarlyView.
Imaging mass cytometry shows lupus panniculitis lesions are dominated by cytotoxic and skin‐homing T cells with abundant macrophages and B‐cell aggregates. Spatial neighborhood analysis reveals organized leukocyte architecture, including B‐cell proximity to naïve T cells and M1 macrophages to cytotoxic T cells.
