MetabolomicsGut microbiota-derived metabolite pantetheine modulates host lipid metabolism to protect against obesity

Obesity is intricately linked to the gut microbiota, yet the microbial effectors and molecular mechanisms that mediate this association remain poorly defined. Fecal microbiome analysis revealed a consistent depletion of the commensal bacterium Roseburia inulinivorans in obese individuals, with it...

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...

MetabolomicsOmega-3 polyunsaturated fatty acids modulate gut microbiota-derived 18β-glycyrrhetinic acid to alleviate type 1 diabetes mellitus

Background

Omega-3 polyunsaturated fatty acids (PUFAs) are known to protect against type 1 diabetes mellitus (T1DM), but how they act through the gut-islet axis is not fully understood. This study explored how Omega-3 PUFA-influenced gut microbiota and their metabolites help protect pancrea...

MetabolomicsSpirulina Prevents Hepatic Steatosis by Promoting Macrophage M2 Polarization via Gut Microbiota-Derived 2-Hydroxy-3-Methylbutyrate
Background & Aims: Spirulina, a microalgae renowned for its nutrient density, shows promise in modulating glucose and lipid metabolism. However, its efficacy and underlying mechanisms against metabolic dysfunction-associated steatotic liver disease (MASLD) remain unclear. We hypothesized that spirul...

MetabolomicsGut-derived metabolites drive Th17 cell pathogenicity in multiple sclerosis

The gut-brain axis is an emerging factor in promoting multiple sclerosis (MS). However, the underlying mechanisms and strategies to target this axis are not established. Here, we investigated how the gut environment influences myelin-specific Th17 cell pathogenicity. We used the adoptive Th17 cel...

MetabolomicsChemotherapy Modulation by a Cancer-Associated Microbiota Metabolite (Targeted metabolomics - 2methylisocitrate)

Understanding how the microbiota produces regulatory metabolites is of significance for cancer and cancer therapy. Using a host-microbe-drug-nutrient 4-way screening approach, we evaluated the role of nutrition at the molecular level in the context of 5-fluorouracil toxicity. Notably, our screens...

MetabolomicsGut Commensal Bacteria-Derived Methionine is Required for Host Reproduction by Modulating RNA m6A Methylation of the Insulin Receptor_targeted metabolites

Gut commensal bacteria promote host reproduction by modulating metabolism and nutrition, but the molecular mechanisms by which microbes regulate reproduction remain unclear. Here, we show that gut commensal bacteria promote host reproduction by providing amino-acid methionine, which controls the ...
