Tailoring a Functional Synthetic Microbial Community Alleviates Fusobacterium nucleatum‐infected Colorectal Cancer via Ecological Control

Advanced Science, EarlyView.
The bottom‐up strategy based on multiomics data is used for the SynCom design, and it successfully inhibited F. nucleatum growth and achieved stable colonization in vivo. In addition, it promoted tryptophan metabolism and secondary bile acid conversion, reduced lipid accumulation, relieved microbiome disorder, decreased inflammatory reaction, and ...

Kynurenine pathway metabolism and neuroinflammatory disease

Neural Regeneration Research, 2017
Immune-mediated activation of tryptophan (TRYP) catabolism via the kynurenine pathway (KP) is a consistent finding in all inflammatory disorders. Several studies by our group and others have examined the neurotoxic potential of neuroreactive TRYP metabolites, including quinolinic acid (QUIN) in neuroinflammatory neurological disorders, including ...

Characterization of the Kynurenine Pathway in Human Neurons [PDF]

The Journal of Neuroscience, 2007
The kynurenine pathway is a major route ofl-tryptophan catabolism producing neuroactive metabolites implicated in neurodegeneration and immune tolerance. We characterized the kynurenine pathway in human neurons and the human SK-N-SH neuroblastoma cell line and found that the kynurenine pathway enzymes were variably expressed.

Mesenchymal Stromal Cell Secretome and Its Key Bioactive Metabolites Induce Long‐Term Neuroprotection After Traumatic Brain Injury in Mice

Advanced Science, EarlyView.
Pischiutta F and coworkers identify prostaglandins and kynurenine as key mediators of the mesenchymal stromal cells‐derived secretome's neuroprotective effects. A synthetic cocktail composed of these factors promotes long‐term functional recovery, reduces brain structural damage, and modulates neuroinflammation after traumatic brain injury, supporting ...

Harnessing nanomaterials to precisely regulate the immunosuppressive tumor microenvironment for enhanced immunotherapy

BMEMat, EarlyView.
The immunosuppressive tumor microenvironment, characterized by hypoxia, redox imbalance, elevated interstitial fluid pressure, and acidity, was comprehensively elucidated. This review discussed the etiology and consequences of the characteristics of the immunosuppressive tumor microenvironment, and analyzed the recent advancements in nanomaterials for ...

Plasma metabolomics identifies signatures that distinguish heart failure with reduced and preserved ejection fraction

ESC Heart Failure, EarlyView.
Abstract Aims Two general phenotypes of heart failure (HF) are recognized: HF with reduced ejection fraction (HFrEF) and with preserved EF (HFpEF). To develop phenotype‐specific approaches to treatment, distinguishing biomarkers are needed. The goal of this study was to utilize quantitative metabolomics on a large, diverse population to replicate and ...

Dissecting the enigma of scleroderma: possible involvement of the kynurenine pathway

Pteridines, 2017
The kynurenine pathway (KP) is the metabolic pathway via which L-tryptophan is converted to nicotinamide. It serves important immune-regulatory roles. This article will review the evidence for involvement of the KP in scleroderma and present a possible ...

Mechanical unloading is accompanied by reverse metabolic remodelling in the failing heart: Identification of a novel citraconate‐mediated pathway

European Journal of Heart Failure, EarlyView.
Aims Although functional recovery of the failing heart with left ventricular assist device (LVAD) unloading can occur, the underpinning mechanism is unclear. We aimed to characterize the effect of myocardial biochemical effect of LVAD support in vivo and in vitro.

Intestinal microbiome alterations in pediatric epilepsy: Implications for seizures and therapeutic approaches

Epilepsia Open, EarlyView.
Abstract The intestinal microbiome plays a pivotal role in maintaining host health through its involvement in gastrointestinal, immune, and central nervous system (CNS) functions. Recent evidence underscores the bidirectional communication between the microbiota, the gut, and the brain and the impact of this axis on neurological diseases, including ...
