Salivary Cytokines in Healthy Adolescent Girls: Intercorrelations, Stability, and Associations with Serum Cytokines, Age and Pubertal Stage. [PDF]

, 2013
Theoretically, the measurement of cytokines in saliva may have utility for studies of brain, behavior, and immunity in youth. Cytokines in saliva and serum were analyzed across three annual assessments in healthy adolescent girls (N = 114, 11-17 years at

Weizmannia coagulans XY2 Mitigates Copper Neurotoxicity via Gut–Brain Axis Modulation of Tryptophan Metabolism and Oxidative‐Inflammatory Crosstalk

iMetaOmics, EarlyView.
Copper interferes with tryptophan metabolism and 5‐HT levels by modulating intestinal flora. Intestinal barrier breakdown and inflammatory response trigger nerve damage under copper exposure. W. coagulans XY2 alleviates copper‐induced neurotoxicity by targeting a multi‐dimensional “tryptophan metabolism‐antioxidant defense‐gut‐brain axis” network.

Kynurenines link chronic inflammation to functional decline and physical frailty

JCI Insight, 2020
Chronic inflammation is associated with physical frailty and functional decline in older adults; however, the molecular mechanisms of this linkage are not understood.

Effect of a Single Bout of Aerobic Exercise on Kynurenine Pathway Metabolites and Inflammatory Markers in Prostate Cancer Patients—A Pilot Randomized Controlled Trial

Metabolites, 2020
The kynurenine (KYN) pathway gains growing research interest concerning the genesis, progression and therapy of solid tumors. Previous studies showed exercise-induced effects on metabolite levels along the KYN pathway.

Gestational kynurenine metabolites mediate effects of pregnancy adiposity on child negative affect

Journal of Child Psychology and Psychiatry, EarlyView.
Background Mounting evidence links increased adiposity during pregnancy and offspring risk for mental health disorders. Yet the mechanisms underlying this association remain poorly understood, limiting our ability to design effective interventions.

Reduced calcineurin protein levels and activity in exon-1 mouse models of Huntington's disease: Role in excitotoxicity

Neurobiology of Disease, 2009
Calcineurin is a serine/threonine phosphatase involved in the regulation of glutamate receptors signaling. Here, we analyzed whether the regulation of calcineurin protein levels and activity modulates the susceptibility of striatal neurons to ...

Kynurenine pathway metabolites selectively associate with impaired associative memory function in depression

Brain, Behavior, & Immunity - Health, 2020
Activation of the kynurenine pathway (KP), an important downstream effect of inflammation, is a driver of depression and neurodegeneration. Damage from the end product of KP activation, quinolinic acid, may be responsible specifically for impairment in ...

Exercise‐induced effects on atherogenesis and tryptophan catabolism via the kynurenine pathway in an HIV‐associated atherosclerosis mouse model

Experimental Physiology, EarlyView.
Abstract A mouse model of HIV‐associated atherosclerosis (Tg26+/−ApoE−/−) exhibited increased plaque area compared with the ApoE−/− mouse, linked to elevated indoleamine 2,3‐dioxygenase (IDO) activity. IDO catalyses the conversion of tryptophan (TRP) into kynurenine (KYN), measured by the KYN‐to‐TRP ratio.

Tryptophan metabolite atlas uncovers organ, age, and sex‐specific variations

FEBS Open Bio, Volume 16, Issue 1, Page 52-67, January 2026.
Tryptophan metabolites were analyzed across twelve organs, the central nervous system, and serum in male and female mice at three life stages. We found tissue‐, sex‐, and age‐specific differences, including increased indole‐3‐pyruvate and kynurenine in aging males.
