Antibiotic Remodeling of the Gut Microbiota Impairs Host Resistance to Secondary Infection

iMetaMed, EarlyView.
Gut microbial dynamics induced by four antibiotics, revealed distinct taxonomic and functional shifts. Vancomycin‐perturbed bacteriomes were proven to promote pathogen resistance to antibiotic treatment. Metronidazole‐treated mice showed pronounced Salmonella translocation to hepatic tissue, and altered Enterococcus avium populations modulated host ...

Ginseng polysaccharides prevent mastitis through Lactobacillus murinus‐derived deoxycholic acid and TGR5 signaling

iMetaOmics, EarlyView.
Prebiotic Ginseng polysaccharides (GP) alleviate mastitis through selective enrichment of gut L. murinus, which elevates its anti‐inflammatory metabolite deoxycholic acid (DCA). Circulating DCA engages mammary epithelial TGR5 receptors, triggering the cAMP–PKA pathway to suppress NF‐κB/NLRP3‐mediated inflammation.

Engineered Bacillus subtilis regulates intestinal barrier in ETEC K88‐infected piglets and modulates miR‐1250‐5p/NFκB pathway in IPEC‐J2

iMetaOmics, EarlyView.
Upon enterotoxigenic Escherichia coli (ETEC) K88 infection, intestinal barrier function is disrupted with compromised tight junctions, accompanied by an exacerbated inflammatory response, proliferation of pathogenic Escherichia, and depletion of beneficial Lactobacillus paralimentarius.

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 ...

Involvement of the Kinin B1 Receptor in Increased Permeability of Cerebral Microvessels in Rats Subjected to Autoimmune Encephalomyelitis

Cells
Kinins are vasoactive peptides that are involved in various cellular mechanisms, including the inflammatory response. Kinins, released in vessel walls, exacerbate inflammation by modulating the production and release of pro-inflammatory factors via two ...
