MetabolomicsGut Microbiota–Derived Ergothioneine Alleviates Antipsychotic-Induced Synaptic and Cognitive Impairments

Background: Chronic use of antipsychotic drugs is associated with neuronal damage and cognitive impairment, potentially mediated by alterations in gut microbiota metabolites, although the specific metabolite involved remains unknown.

Objective: To identify the key metabolite responsible for...

MetabolomicsUrine metabolomics phenotyping and urinary biomarker exploratory in mild cognitive impairment and Alzheimer's disease.

INTRODUCTION Alzheimer's disease is a prevalent disease with a heavy global burden and is suggested to be a metabolic disease in the brain in recent years. The metabolome is considered to be the most promising phenotype which reflects changes in genetic, transcript, and protein ...

MetabolomicsAerobic exercise and gut flora: a key link to improved cognitive impairment in mice with Parkinson's disease

Parkinson's disease (PD) is a common neurodegenerative disorder. It is marked by motor dysfunction and cognitive decline. In recent years, scientific studies have found that PD's pathogenesis may be tied to an imbalance in the gut microbiota. This offers new perspectives for PD treatment. Modulat...

MetabolomicsA defined community of core gut microbiota members promotes cognitive performance in honey bees

Gut microbiota across animals have been shown to influence host cognition and behavior. However, it remains unclear whether these cognitive effects are driven by specific bacterial species or arise from community-level interactions. Here, we leveraged the honey bee (Apis mellifera) as a ...

MetabolomicsExtracellular Vesicles from probiotics mediated Walnut green husk polysaccharide alleviates ochratoxin-A-induced cognitive impairment via SCFA and 5-HT mediated microbiota-gut-brain axis

BACKGROUND: Ochratoxin A (OTA) have made it a serious hazard to food safety worldwide that poses a serious health risk to humans. Our previous research showed that Walnut green husk polysaccharides (WGP) can effectively alleviate intestinal inflammation and intestinal microbiota ...

MetabolomicsAlterations in gut microbiota composition, plasma lipids, and brain activity, suggest inter-connected pathways influencing malnutrition-associated cognitive and neurodevelopmental changes.

Malnutrition affects over 30 million children annually and has profound immediate and enduring repercussions, with nearly half of child deaths under five linked to malnutrition. Survivors face lasting consequences, including impaired neurocognitive development, leading to cognitive and behavioura...

TranscriptomicsDeep Sleep and Parietal Cortex Gene Expression Changes are Related to Cognitive Deficits with Age
Background: Age-related cognitive deficits negatively affect quality of life and can presage serious neurodegenerative disorders. Despite sleep disruption’s well-recognized negative influence on cognition, and its prevalence with age, surprisingly few studies have tested sleep’s relationship to cogn...

TranscriptomicsDistinct DNA methylation patterns of cognitive impairment and Trisomy 21 in Down Syndrome
The presence of an extra whole or part of chromosome 21 in people with Down syndrome (DS) is associated with multiple neurological changes, including pathological aging that often meets the criteria for Alzheimer’s Disease (AD). While the mechanism underlying these changes is unknown, it has been hy...

MetabolomicsA gut Eggerthella lenta–derived metabolite impairs neutrophil function to aggravate bacterial lung infection
The “gut-lung” axis is crucial for the chronic infection in bronchiectasis. However, the responsible microbe and the mechanism in the “gut-lung” axis of bronchiectasis are still in demand for precise elucidation. Here, we reported that Eggerthella lenta in the gut and taurine ursodeoxycholic acid (T...
