Summary: Pneumococcal pneumonia is a major cause of disease and death worldwide, with compromised immune function and an insufficient dietary intake of zinc increasing the risk. This study reveals the critical role of the zinc transporter ZIP8 in host defense and the adverse impact of a common defective ZIP8 allele on the gut microbiota essential for lung immunity. Loss of ZIP8 function leads to intestinal dysbiosis and impaired host defense in the lung, highlighting the need for further investigation and improved surveillance and treatment strategies given the high incidence of dietary zinc deficiency and the ZIP8 variant allele in the human population.

Summary: Emerging evidence suggests that atherosclerosis is a chronic inflammatory disease and immune cells play critical roles in vascular inflammation and plaque formation. Gastrointestinal disorder is considered a risk factor in mediating the atherosclerotic process. This study demonstrates the pharmacological benefits of sivelestat in protecting against atherosclerosis and the important role of intestinal homeostasis in atherosclerotic development.

Summary: Intestinal dysbiosis increases susceptibility to infection due to metabolic profile changes, resulting in increased morbidity. The study found that ZIP8, a type of zinc transporter, is important for myeloid cells in maintaining host defense against bacterial pneumonia. Furthermore, a common variant of ZIP8 is closely associated with inflammation-based disorders and bacterial infection. The researchers developed a new model to study the effects of ZIP8-mediated intestinal dysbiosis on pulmonary host defense, independent of genetic factors. The results showed that the intestinal microbiota, regardless of host genetics, play a crucial role in regulating host defense in the lung against infection. These findings support future microbiome-based intervention studies, considering the high prevalence of zinc deficiency and the rs13107325 allele in humans.

Summary: Bacillus coagulans MZY531 has a protective effect on intestinal mucosal injury in immunosuppressed mice induced by cyclophosphamide. It promotes the expression of immune proteins, regulates intestinal inflammation and cellular repair. Furthermore, it can modulate the gut microbiota by increasing the abundance of beneficial bacteria. In conclusion, B. coagulans MZY531 has potential immunomodulatory activity.

Summary: Manganese and zinc are essential micronutrients that play a crucial role in regulating host immune response against infections. The metal transporter ZIP8 plays a key role in metal uptake and affects host defense mechanisms. Perturbations in metal homeostasis may impact the composition of bacterial communities in the host. Therefore, understanding the importance of zinc and manganese uptake is important for the development of intervention strategies against infectious diseases.

Summary: The intact intestinal barrier is crucial for maintaining health, and bacteria along with their products are shown to contribute to its impairment. Alterations in tight junction integrity can lead to increased influx of bacteria into the host circulation, potentially contributing to metabolic diseases like obesity and insulin resistance.

Summary: The study revealed that moderately malnourished mice infected with malaria had lower parasite burden at the peak of infection, but showed damaged mucosal epithelial cells, increased intestinal permeability, shortened small intestine, and decreased number of innate immune cells in the large intestine. Despite lower numbers, macrophages in the moderately malnourished mice were highly activated in the small intestine, indicating exacerbation of some abnormalities in the gut induced by the moderate malnutrition.

Summary: This review comprehensively discusses the impact of typical nanomaterials on the intestinal mucosal barrier (IMB) and summarizes the treatment of intestinal diseases by using nanomaterials. Factors such as dosage, size, morphology, and surface functional groups of nanomaterials influence the effects on the IMB. There is huge potential for nanomaterials to regulate the IMB and achieve optimal therapeutic effects for antibiotics, oral vaccines, and drug carriers.

Summary: Glu-derived zwitterionic micelles have promising potential for oral delivery, with the ability to overcome the mucosal barrier, excellent mucus permeability, and enhanced cellular internalization capacity. The endocytosis was mediated by multiple amino acid transporters and the retrograde pathway played an important role in intracellular transport and transcytosis. The excellent villi absorption observed in situ provides convincing evidence for the potential of oral delivery.

Summary: This clinical trial investigated the effects of brown and golden flaxseeds on various health indicators in perimenopausal overweight women. The results showed that flaxseed consumption reduced intestinal permeability and improved lipid profiles, demonstrating positive effects on metabolic changes caused by menopausal transition.

Summary: The use of probiotics did not lead to significant clinical improvement in NAFLD patients in terms of hepatic steatosis and fibrosis levels, but at the microenvironment level, probiotics seemed to stabilize mucosal immune function and protect patients against increased intestinal permeability. Further studies with larger sample sizes and different probiotic strains are needed to evaluate the true benefit of probiotics in NAFLD.

Summary: Total parenteral nutrition (TPN) is a critical intervention for infants unable to feed orally, but prolonged reliance on TPN poses a risk of liver injury, particularly through parenteral nutrition associated cholestasis (PNAC) driven by lipid emulsions. Studies suggest that new emulsions containing fish oil and medium chain triglycerides show promise in reducing the incidence of PNAC.

Summary: Necrotizing enterocolitis (NEC) is the leading cause of death caused by gastrointestinal disease in preterm infants. Major risk factors include prematurity, formula feeding, and gut microbial colonization. Probiotics have been shown to reduce NEC incidence in infants, but their effectiveness depends on the specific species used.

Summary: The study found that preterm pigs fed with donor human milk had higher concentrations of liver beta-carotene compared to those fed with premature infant formula. However, liver vitamin A stores were higher in pigs fed with infant formula. Additionally, plasma, liver, and jejunum concentrations of lutein, zeaxanthin, and lycopene were higher in pigs fed with donor human milk. The study suggests that further research should be conducted to investigate the bioactivity and bioavailability of carotenoids in infants.

Summary: The impact of birth modality and gestational age on hormone levels, gene expression, and plasma levels of FGF19 in neonatal pigs was investigated. Vaginally born piglets had significantly higher plasma FGF19 levels at birth compared to cesarean and preterm piglets. However, FGF19 gene expression in the distal ileum was similar among all groups. Plasma FGF19 was positively correlated with plasma cortisol, and dexamethasone treatment increased FGF19 expression in pig tissue and human enteroids.
