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.

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

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.

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.

Serotonin Degradation and Lipid Metabolism Regulate Human Tc2 Cell Effector Functions

Allergy, EarlyView.
Human Tc2 cells exhibit a metabolically active phenotype characterized by enhanced glycolysis, mitochondrial respiration, and fatty acid uptake dependent on PPARγ. Alarmins strongly amplify IL‐5 and IL‐13 production in Tc2 cells, supporting a shared immunometabolic program across type 2 lymphocytes.

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, EarlyView.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive
