Variation in Microbiome Composition and Faecal Metabolites Are Associated With Differential Susceptibility to DSS‐Induced Colitis

Immunology, EarlyView.
C57BL/6 mice from Charles River Laboratories (CR) have enhanced mucosal immune action relative to C57BL/6 mice from Jackson Laboratories (JAX). CR mice are more susceptible to severe DSS‐induced colitis than JAX mice. Co‐housing transfers colitis susceptibility from CR mice to JAX mice.

Tryptophan‐Derived Microbial Metabolite Indole‐3‐Acetic Acid Ameliorates Periodontitis Through AhR/CYP1A1‐Mediated Macrophage Polarisation

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim To investigate the association between tryptophan‐derived microbial metabolites and periodontitis, and to assess whether the differential tryptophan metabolite indole‐3‐acetic acid (IAA) could ameliorate periodontitis and elucidate its potential mechanism.

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.

Xanthurenic acid and its rôle in the trytophane metabolism of pyroxidine-deficient rats [PDF]

, 1943
In a previous publication (1) the isolation of a green pigment from the urine of pyridoxine-deficient rats was described. The green pigment was shown to be the product of a reaction between ferric ammonium sulfate or other ferric salts and a compound ...

Glutamate and opioid antagonists modulate dopamine levels evoked by innately attractive male chemosignals in the nucleus accumbens of female rats [PDF]

, 2017
Sexual chemosignals detected by vomeronasal and olfactory systems mediate intersexual attraction in rodents, and act as a natural reinforcer to them.

A history of suicide attempts among individuals with schizophrenia is associated with tryptophan degradation via the salivary kynurenine pathway

BMC Psychiatry
Background Tryptophan, an essential precursor metabolite within the kynurenine pathway, has been implicated in the neurobiological mechanisms underlying both schizophrenia and associated suicidality. Despite this link, the lack of validated biomarkers to

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.

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 ...
