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.

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.

The Kynurenine Pathway

, 2012
The kynurenine pathway represents a major route for the catabolism of tryptophan (TRP). In the body, TRP is transported around the periphery either bound to albumin (90%) or in free form (10%), the two states existing in equilibrium (McMenamy 1965). However, only free form TRP can be transported across the blood-brain barrier (BBB) by the competitive ...

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.

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

Identification of kynurenine and quinolinic acid as promising serum biomarkers for drug-induced interstitial lung diseases

Respiratory Research
Background Drug-induced interstitial lung disease (DILD) is a lung injury caused by various types of drugs and is a serious problem in both clinical practice and drug development.

Brain viral reservoir seeding and neurological metabolic dysregulation in early‐life immunodeficiency virus infection

Brain Pathology, EarlyView.
Brain viral reservoirs were undetectable in neonatal SIV during the first 3 days post infection; antiretroviral therapy (ART) at 3 dpi prevented brain reservoir seeding and normalized metabolic function, highlighting the necessity of very early treatment to protect the developing CNS.

Inhibition of kynurenine 3‐monooxygenase (KMO) reduces fentanyl and sucrose intake and relapse‐like behaviour in rats

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Opioid use disorder, particularly involving fentanyl, poses major challenges due to high relapse rates and limited effectiveness of pharmacotherapies. The kynurenine pathway has emerged as a target for addiction treatment through its modulation of glutamatergic and dopaminergic neurotransmission.
