Macrophage extracellular vesicles deliver Mef2d proteins to aggravate Bacteroides fragilis pathogenicity in type 2 diabetes arterial calcification

Interdisciplinary Medicine, EarlyView.
Bacteroides fragilis is associated with type 2 diabetes (T2D) arterial calcification and can be activated by macrophage‐derived extracellular vesicles (EVs). BF takes up EVs via receptor‐mediated endocytosis, and activation is induced by EV‐derived Mef2d, thereby inhibiting ArsR family transcriptional regulator transcription.

Microbial metabolite indole‐3‐propionic acid preserves astrocytic mitochondrial mitofusin 2 to limit neuroinflammation after traumatic brain injury

Interdisciplinary Medicine, EarlyView.
Following traumatic brain injury, indole‐3‐propionic acid (IPA) directly targets the aryl hydrocarbon receptor on astrocytes in the peri‐lesional cortex; this suppresses interferon regulatory factor 1‐driven transcription of the E3 ubiquitin ligase RFFL (ring finger and FYVE‐like domain containing E3 ubiquitin protein ligase).

Trimethylamine N-oxide impairs β-cell function and glucose tolerance

Nature Communications
β-Cell dysfunction and β-cell loss are hallmarks of type 2 diabetes (T2D). Here, we found that trimethylamine N-oxide (TMAO) at a similar concentration to that found in diabetes could directly decrease glucose-stimulated insulin secretion (GSIS) in MIN6 ...

Trimethylamine N-Oxide Exacerbates Cardiac Fibrosis via Activating the NLRP3 Inflammasome

Frontiers in Physiology, 2019
Background/Aims: Gut microbiota has been reported to correlate with a higher mortality and worse prognosis of cardiovascular diseases. Trimethylamine N-oxide (TMAO) is a gut microbiota-dependent metabolite of specific dietary nutrients, which is linked ...

A Comprehensive Study of Bidirectional Interactions Between the Human Microbiome and Blood Malignancies and Hematologic Conditions: Focus on Novel Therapeutic Strategies

Journal of Clinical Laboratory Analysis, EarlyView.
Microbiota‐targeted therapeutic strategies in hematological disorders. aHSCT: Transplanted immune cells from the donor may attack the recipient's tissues, especially when damage to the intestinal epithelium disrupts the gut microbiota, contributing to GVHD. Maintaining a balanced gut microbiota that supports immune regulation helps reduce GVHD risk and

Divergence between circulating trimethylamine and trimethylamine-N-oxide associated with common flavin-containing monooxygenase 3 variation

iScience
Summary: Flavin-containing monooxygenase 3 (FMO3) oxidizes trimethylamine (TMA), a gut-derived metabolite of dietary substrates such as choline and betaine, into trimethylamine-N-oxide (TMAO), which has been linked to cardiometabolic and renal diseases ...

Metabolic Dysfunction‐Associated Steatotic Liver Disease and Obesity: Pathogenesis, Diagnostics, Risk Stratification, and Therapeutic Approach

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Metabolic dysfunction‐associated steatotic liver disease (MASLD) has emerged as the most prevalent chronic liver disease worldwide, closely linked to the global rising incidence of obesity and metabolic syndrome. This review synthesizes current evidence on the pathogenesis, gut–liver axis, and multidisciplinary management of MASLD within the ...

Toxicity Differences Between Microplastics and Nanoplastics in Organs: From Molecular Mechanisms to Potential Therapeutic Strategies

Med Research, EarlyView.
This review systematically compares the size‐dependent toxicity of microplastics and nanoplastics in the intestine, liver, kidney, lung, and brain. Particle size determines bioavailability, barrier penetration, and injury mechanisms. Because of their small size and high surface reactivity, NPs readily cross the intestinal epithelium and blood–brain ...
