Regulatory Effects of Ammonium Chloride in an In Vitro Model of Hepatic Encephalopathy: Mechanisms Involving ACTA2‐Mediated Cytoskeletal Remodeling

iLABMED, EarlyView.
Hyperammonemic stress suppresses ACTA2 expression and induces F‐actin cytoskeletal remodeling in astrocytes. The resulting inhibition of FAK/c‐Src signaling contributes to apoptosis, G2/M arrest, AQP4‐mediated swelling and junction‐associated proteins dysregulation, revealing a central role for ACTA2‐dependent cytoskeletal dysfunction in hepatic ...

Microbial keystone taxa and metabolic signatures in centenarians regulate intestinal homeostasis during aging

iMeta, EarlyView.
Clostridium scindens and its metabolite indole‐3‐acetic acid (IAA) are identified as a keystone taxon and metabolic signature in centenarians. Clostridium scindens enhances microbial network stability and produces IAA via its own amidase (AMIE) and aldehyde dehydrogenase (ALDH), thus promoting intestinal homeostasis by activating the aryl hydrocarbon ...

Immune Checkpoint Inhibitors Induce Intestinal Epithelial Injury and a Senescence‐Like Phenotype

iNew Medicine, EarlyView.
ICI treatment promotes the infiltration of activated immune cells into the intestinal mucosa. This inflammatory microenvironment is associated with significant epithelial injury, characterized by the disruption of the epithelial barrier, the depletion of specialized secretory cell lineages, and the induction of a premature senescence phenotype ...

The Endothelial CXCR Family in Vascular Health and Disease

iNew Medicine, EarlyView.
ABSTRACT Endothelial cells (ECs) form the dynamic interface between blood and tissue, serving as key regulators of vascular homeostasis, inflammation, and repair. Among the molecular systems governing endothelial behavior, the C‐X‐C motif chemokine receptor (CXCR) family—originally characterized in immunology for its roles in leukocyte trafficking and ...

Tiny carriers, big impact: How Fusobacterium nucleatum extracellular vesicles drive oral diseases and beyond

Interdisciplinary Medicine, EarlyView.
This review explores how Fusobacterium nucleatum extracellular vesicles drive local oral diseases and distal pathologies via sophisticated cross‐compartment cross talk. It highlights the transformative potential of these “tiny carriers” as next‐generation molecular intermediaries for advanced health monitoring and innovative bio‐interventions by ...

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).

Colonic Barrier Dysfunction and Inflammation Induced by Nano‐/Micro‐Plastics Fibers in Mice via the FAK/NF‐κB/iNOS and TLR4/NF‐κB/iNOS Pathways

Journal of Applied Toxicology, EarlyView.
ABSTRACT As emerging environmental contaminants, nano‐ and micro‐plastics (NMPs) have drawn increasing research attention due to potential hazards to organisms. Particle shape is a key factor influencing the toxic effects of NMPs, and NMPs of different shapes cause varying degrees of tissue damage. We investigated the specific mechanisms of polystyrene

Air Pollution Quinones Impair Intestinal Barrier Integrity and Endoplasmic Reticulum in Differentiated Caco‐2 Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Particulate matter (PM) is a major global health threat, linked to millions of deaths annually. Beyond inhalation, PM components reach the gastrointestinal tract through the mucociliary escalator or contaminated food and water. Among PM's organic fraction, redox‐active quinones such as 1,2‐naphthoquinone (NQ) and 9,10‐phenanthrenequinone (PQ ...
