MetabolomicsVitamin D deficiency disrupts a host–microbiota bile acid axis in aged mice to drive Faecalibaculum rodentium expansion and intestinal epithelial barrier dysfunction
This study investigated how vitamin D deficiency alters the fecal metabolome and bile acid metabolism in mice and evaluated the contribution of Faecalibaculum rodentium bile salt hydrolase activity to intestinal epithelial barrier dysfunction. Two complementary mouse experiments were included. In th...

MetabolomicsF-actin dynamics couples sphingolipid metabolism to epithelial barrier integrity in chronic colitis
Intestinal barrier dysfunction is a hallmark of gastrointestinal disorders, including inflammatory bowel diseases (IBD). In IBD, the disruption of the gut barrier causes liquid loss and persistent immune response. Understanding the cellular events underlying epithelial barrier disruption during chro...

MetabolomicsEarly-Life Intervention with Lactobacillus reuteri Enhances Intestinal2 Barrier Function and Resilience in Suckling Piglets via Modulation of3 Gut Microbiota and Metabolites
Early-life nutritional interventions are pivotal for promoting piglet growth and health, particularly in reducing weaning-associated disorders. This study investigated the effects of early-life Lactobacillus reuteri (L.reuteri) supplementation on growth performance, immune function, intestinal morph...

ProteomicsLack of intestinal Mucin-1 impairs intestinal epithelial barrier and promotes metabolic dysfunction-associated steatotic liver disease in mice
Accumulating evidence suggests that a compromised intestinal epithelial barrier (IEB) contributes to the progression of metabolic dysfunction-associated steatotic liver disease (MASLD); however, the exact mechanisms remain unclear. Here we reveal that intestinal mucin 1 (MUC1) levels and glycosylati...

TranscriptomicsDifferential Targeting of the E-Cadherin and b-Catenin Complex by Gram-positive Probiotic Lactobacilli Improves Epithelial Barrier Function
The intestinal ecosystem is balanced by dynamic interactions between resident and incoming microbes, the gastrointestinal barrier, and the mucosal immune system. However, in the context of inflammatory bowel diseases (IBD) where the integrity of the gastrointestinal barrier is compromised, resident ...

TranscriptomicsExpression data from HT29 intestinal epithelial cell line
The study recapitulates, through in vitro micropatterned co-cultures, interactions between HIV-infected T-lymphocytes and intestinal epithelial cells in order to investigate the mechanisms underlying the disruption of normal epithelial cell and barrier function during HIV infection. The co-culture m...

MetabolomicsDual Effects of Fasting on Gut Microbiota and Metabolism: Protective Adaptation versus Barrier Dysfunction Risks
Fasting is increasingly recognized as a metabolic intervention that reshapes gut microbiota and host metabolism, but its duration-dependent effects on intestinal epithelial integrity remain incompletely understood. In this study, we compared ad libitum feeding, 12 h fasting, and 24 h fasting in male...

MetabolomicsAlterations in the gut microbiota and metabolic profiles coincide with intestinal damage in mice with a bloodborne Candida albicans infection
Candida albicans is an opportunistic fungus that can threaten life especially in patients with candidemia. The morbidity and mortality of candidemia originating from a central venous catheter (CVC) and illicit intravenous drug use (IVDU) are increasing. However, the mechanism underlying the bloodbor...

ProteomicsMechanistic Insight into Human Milk Extracellular Vesicle-Intestinal Barrier Interactions
Human milk extracellular vesicles (EVs) are crucial mother-to-baby messengers that transfer biological signals. These EVs are reported to survive digestion and transport across the intestine. The mechanisms of interaction between human milk EVs and the intestinal mucosa, including epithelial uptake ...

TranscriptomicsThe acetylome regulators Hdac1 and Hdac2 differently modulate intestinal epithelial cell dependent homeostatic responses in experimental colitis
Histone deacetylases (Hdac) remove acetyl groups from proteins, influencing global and specific gene expression. Hdacs control inflammation, as shown by Hdac inhibitor-dependent protection from DSS-induced murine colitis. While tissue-specific Hdac knockouts show redundant and specific functions, li...
