Intestinal mucosal barrier damage is closely associated with the development of several intestinal inflammatory diseases. Isoquercitrin (IQ) is a natural flavonoid compound derived from plants, which exhibits high antioxidant and anti-inflammatory activity with minimal side effects in humans. Therefore, it shows great potential for preventing and treating intestinal mucosal barrier damage. This study aims to investigate the ameliorative effect and mechanism of IQ on lipopolysaccharide (LPS)-induced intestinal mucosal barrier damage in mice. The mice were treated with IQ for 7 days and then injected with LPS to induce intestinal mucosal barrier damage. The results revealed that IQ treatment alleviated LPS-induced intestinal mucosal barrier damage in mice, which can be evidenced by the improvements in intestinal morphology and the promotion of expression in intestinal tight junctions (ZO-1, Claudin-1, and Occludin), as well as MUC2 mucin. IQ also attenuated intestinal inflammatory responses by inhibiting the TLR4/MyD88/NF-κB signaling pathway and reducing the expression and plasma levels of IL-6, IL-1β, and TNF-α. Furthermore, IQ significantly increased the relative abundance of beneficial bacteria, including Dubosiella, Akkermansia muciniphila and Faecalibaculum rodentium, while suppressing the growth of harmful bacteria such as Mucispirillum schaedleri in the intestinal flora of mice. Consequently, IQ can alleviate the LPS-induced intestinal mucosal barrier damage in mice by inhibiting the TLR4/MyD88/NF-κB signaling pathway and modulating the intestinal flora.

Food & Function

Food & Function provides a unique venue for physicists, chemists, biochemists, nutritionists and other food scientists to publish novel, cutting-edge, original research focussing on food, its nutrients and their relation to human health and nutrition. We welcome research describing the: Physical properties and structure of food and how this relates to sensory perception and human health Biochemical and physiological actions of food components Interactions between foods, gut microbiota and human physiology Nutritional and biological evaluation of food Clinical and population studies using food or food components Development of biomarkers of food intake and effects on human health We also welcome systematic reviews and meta-analyses of existing studies in the literature, provided these are objective and scientifically valid Food in this context is defined as materials of plant, animal or mineral origin, which are consumed orally (by humans) for pleasure and to sustain growth and vital processes. Examples of research topics that are of interest to be published in Food & Function are: Chemistry and physics of food components and digestion processes Relationship between the physical properties/structure of food and nutrition and human health - for example, impact of food matrix or processing on nutrient release and uptake Molecular properties and physiological effects of food components (nutrients, fibres, essential micronutrients, phytochemicals, bioactives, food substitutes, novel ingredients, allergens, flavours and fragrances) Nutritional and health effects of food including bioavailability and metabolism assessment of food components (nutrients, micronutrients and other microconstituents) Efficacy and mechanisms of food constituents in the body - including biomarkers of intakes, exposure and effects Impacts of foods/food components on gut microorganisms and human physiology - For example impact of fermented foods Role of nutrition and diet in human disease prevention and development Cellular and molecular effects/mechanisms of food/food components image block The following types of research are not within the scope of Food & Function: Research relating to traditional herbal medicines, medicinal plants or active compounds extracted from such plants (materials that are primarily consumed as medicine, i.e. the intended purpose is primarily to treat, cure or prevent a non-deficiency disease) or relating to foods not recognised as human diet contributors Animal nutrition research that is not primarily designed as a model to benefit human nutrition (for example, studies of growth/accretion, heat stress, weaning, ruminant digestion, meat quality, etc.) Treatments administered by non-oral routes such as injection (subcutaneous, intramuscular, intraperitoneal, etc.), dermal/transdermal, rectal, inhalation, nasal, etc. Exceptions are when such routes of administration are used for mechanistic/control purposes in the experimental design Pharmacological/pharmaceutical approaches: Encapsulation, emulsification and/or pure controlled release of compounds or bioactives that do not come directly from edible foods, such as dietary supplements - these are better suited to a pharmaceutical journal In vitro or in vivo studies with poorly defined (insufficiently characterised) extracts and studies without appropriate controls will not be considered Cells studies not considering the metabolism of food components ingested – for example, irrelevant exposure of cells to compounds not present in the body after absorption Manuscripts with only a fully theoretical/bioinformatic approach and without appropriate support from analytical evidence will not be considered for publication Studies focussing solely on food engineering, preservation and sustainable technologies – these can be published in our companion journal Sustainable Food Technology Pure food analysis - these can be published in Analytical Methods
