Microbiome‐Derived Tryptophan Metabolites Regulate AhR Signaling to Restore Epithelial Barrier Integrity in Inflammatory Bowel Disease

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
The graphical abstract illustrates how microbiome‐derived indoles activate the aryl hydrocarbon receptor to restore the intestinal barrier. The picture contrasts the “leaky gut” state with the restored homeostasis achieved through AMPK, Nrf2, and IL‐22 signaling.

Inflammatory activation of the kynurenine pathway : studies with lipopolysaccharides

, 2020
Neuroinflammation is increasingly recognised as playing an important role in several major psychiatric disorders. The mechanisms by which neuroinflammation influences neurotransmitter systems have for long been unknown. However, the kynurenine pathway, a

The Kynurenine Pathway in Gut Permeability and Inflammation

Inflammation
Abstract The gut-brain axis (GBA) is a crucial communication network linking the gastrointestinal (GI) tract and the central nervous system (CNS). The gut microbiota significantly influences metabolic, immune, and neural functions by generating a diverse array of bioactive compounds that modulate brain function and maintain homeostasis.

Phthalate Metabolite, Mono(2‐Ethyl‐5‐Hydroxyhexyl) Phthalate (MEHHP), Promotes Uterine‐Fibroid–Associated Phenotypes in Myometrial Stem Cell‐Derived 3D Organoids

Environmental Toxicology, Volume 41, Issue 10, Page 975-997, October 2026.
ABSTRACT This study investigates how phthalate exposure contributes to uterine fibroid (UF) development by studying the effects of the Mono‐(2‐ethyl‐5‐hydroxyhexyl) phthalate (MEHHP), a metabolite of Di(2‐ethylhexyl) phthalate, on myometrial stem cells (MMSCs).

The Kynurenine Pathway: a Proposed Mechanism Linking Diabetes and Periodontal Disease in Diabetic Patients

Dental Hypotheses, 2011
Introduction: Diabetes mellitus is a metabolic disease characte-rized by dysregulation of carbohydrate, protein and lipid metabolism. Diabetes could result, in part, in activation of tryptophan metabolism.

Multi‐Component Functionalized Bifidobacterium Longum Hydrogel for Multi‐Target Integrated Therapy of Colitis‐Associated Anxiety and Depression

Advanced Science, Volume 13, Issue 52, 18 September 2026.
A pH/MMP dual‐responsive Bifidobacterium longum (BL) hydrogel (INPs@BL@Gel) functionalized with baicalin, tyrosine, and inulin is constructed. It enables gastric protection, inflammation‐targeted release, and prolonged intestinal colonization. By remodeling gut microbiota, elevating beneficial neuroactive metabolites (homovanillic acid, short‐chain ...

Targeted Delivery of Indole‐3‐Pyruvic Acid Suppresses Macrophage Ferroptosis to Enhance CD8+ T Cell‐Mediated Immunotherapy Response in Bladder Cancer

Advanced Science, Volume 13, Issue 53, 24 September 2026.
A microbiota‐derived metabolite, indole‐3‐pyruvic acid, suppresses macrophage ferroptosis through the AHR–NF‐κB–SLC7A11 axis. This preserves CD8+ T cell function in bladder cancer. Macrophage‐targeted nanoparticles enhance indole‐3‐pyruvic acid delivery and overcome resistance to PD‐1 blockade.

Slc44a2 Deficiency Unveils an IFN‐I–Dependent Feedback Control of pDC Egress

Advanced Science, Volume 13, Issue 53, 24 September 2026.
Working model of SLC44A2‐mediated maintenance of pDC homeostasis. This model illustrates two central mechanisms by which SLC44A2 regulates pDC homeostasis: (1) SLC44A2 limits IFN‐I production by exporting amino acids (T, N, Q), thereby preventing spontaneous pDC activation.

Perinatal lead (Pb) exposure and alterations to amyloid beta and metabolic profiles in the brain

Alzheimer's &Dementia, Volume 22, Issue 9, September 2026.
Abstract INTRODUCTION Developmental neurotoxicant exposures (e.g., lead [Pb]) are suspected contributors to dementia. Dementia is characterized by amyloid beta (Aβ) plaques and dysregulated metabolism. To better understand the relationship between environment and dementia risk, we assessed the impact of perinatal Pb exposure on dementia‐related ...
