In some organs, such as the brain, endothelial cells form a robust and highly selective blood-to-tissue barrier. However, in other intestine, provide less stringent permeability, to allow rapid exchange of solutes nutrients where needed. To maintain structural functional integrity dynamic blood-brain gut-vascular barriers, specialized cell-cell junctions, known adherens junctions tight junctions.

Altered intestinal permeability plays a role in many pathological conditions. Intestinal is component of the barrier. This barrier dynamic interface between body and food pathogens that enter gastrointestinal tract. Therefore, dietary components can directly affect this interface, metabolites produced by host enzymes or gut microbiota act as signaling molecules exert direct effects on Our aim was to examine diet health disease states.

Nonalcoholic fatty liver disease (NAFLD) is a chronic condition affecting one quarter of the global population. Although primarily linked to obesity and metabolic syndrome, undernutrition altered (dysbiotic) gut microbiome influence NAFLD progression. Both prevalence are predicted considerably increase, but how undernourished contributes hepatic pathophysiology remains far less studied. Here, we present conditions with features, including kwashiorkor micronutrient deficiency. We then review microbiota-liver axis, highlighting key pathways progression within both overnutrition undernutrition.

Obesity, insulin resistance (IR), and the gut microbiome intricately interplay in Metabolic-associated Steatotic Liver Disease (MASLD), previously known as Non-Alcoholic Fatty (NAFLD), a growing health concern. The complex progression of MASLD extends beyond liver, driven by "gut-liver axis," where diet, genetics, gut-liver interactions influence disease development. pathophysiology involves excessive liver fat accumulation, hepatocyte dysfunction, inflammation, fibrosis, with subsequent risk hepatocellular carcinoma (HCC). gut, tripartite barrier, mechanical, immune, microbial components, engages constant communication liver. Recent evidence links dysbiosis disrupted barriers to systemic inflammation progression. Toll-like receptors (TLRs) mediate immunological crosstalk between recognizing structures triggering immune responses.

Clinical management strategies encompass dietary interventions, physical exercise, pharmacotherapy targeting bile acid (BA) metabolism, modulation approaches through prebiotics, probiotics, symbiotics, fecal microbiota transplantation (FMT).
