Summary: Nickel is an important metal that widely exists in nature and is necessary for human beings and animals as a trace element. Excessive nickel exposure can induce excessive free radicals in the body, causing damage to cells and negatively affecting overall health, particularly in the intestine.

Summary: Intestinal barrier dysfunction plays a critical role in severe acute pancreatitis (SAP), and interleukin-22 (IL-22) is a key regulator of this barrier. IL-22 is activated in the pancreas and colon during SAP, but declines faster than other proinflammatory cytokines. Colonic IL-22 can improve intestinal barrier dysfunction by reducing mucosal permeability, upregulating E-cadherin and ZO-1 expression, activating the pSTAT3/Reg3 pathway, and restoring fecal microbiota abundance.

Summary: Recent studies have shown that intestinal microecological disorders not only affect the digestive system but also have wider physiological effects. This paper focuses on pathological animal models that simulate different types of stress and discusses the effects of stress on the organism and the intestinal barrier, as well as the implications for microecological health.

Summary: This study found that Brucea javanica oil (BJO) has the potential to protect against 5-FU-induced chemotherapeutic intestinal mucosal injury (CIM), and explored the mechanisms involved. The results showed that BJO can alleviate CIM by regulating oxidative stress, inflammation, intestinal epithelial cell apoptosis and proliferation, intestinal tight junction proteins, and the activation of the Nrf2/HO-1 pathway.

Summary: One of the primary functions of the intestinal epithelium is to regulate the transport of fluid and electrolytes. Under normal circumstances, absorption is predominant, enabling conservation of water. However, in secretory diarrhea, excessive fluid secretion overwhelms absorption, leading to water loss in stool. This review discusses the regulation of Cl- and fluid secretion in the intestine, dysregulation in secretory diarrhea, therapeutic approaches, and innovative strategies for treating constipation by exploiting intestinal secretory mechanisms.

Summary: T-helper 22 (Th22) cells are a novel subset of CD4(+) T cells that secrete IL-22 while abstaining from secreting IL-17 and IFN-?. These cells are considered as the primary source of IL-22 and are believed to contribute to maintaining intestinal mucosal homeostasis in IBD. However, the exact functions of Th22 cells and IL-22 in this context are still debated. This study aims to provide an overview of the molecular structure characteristics and functional effects of Th22 cells and IL-22, as well as explore targeted treatment approaches and potential therapeutic strategies focusing on the Th22 and IL-22 pathways.

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: Acute and chronic intestinal inflammation can cause epithelial damage, and cells in the wound milieu secrete signaling molecules to influence repair. This study shows that BLT1, a receptor for lipid mediators, is expressed in intestinal epithelial cells and plays a role in promoting migration and proliferation of these cells during wound repair. In mouse models, the absence of BLT1 led to impaired intestinal wound healing. These findings reveal a novel mechanism involving BLT1 signaling in the repair of intestinal epithelial wounds.

Summary: This study investigated the protective effect of American ginseng dietary fiber (AGDF) on intestinal mucosal barrier injury in immunosuppressed mice. The results showed that AGDF could enhance immunity and stabilize the intestinal mucosal barrier, suggesting its potential as a dietary supplement for preventing and treating intestinal mucosal barrier injury.

Summary: The dysfunctional immune system in the intestinal mucosa with age promotes the occurrence of age-associated diseases. While there have been numerous studies on the impact of aging on systemic immunity, the research on the impact of aging on the intestinal mucosal immune system is relatively limited. This review briefly introduces the effects of aging on the intestinal mucosal barrier, immune cells, immune molecules, and the interaction between intestinal mucosal immunity and gut microbiota during aging. Additionally, potential strategies to slow down intestinal aging in the elderly are discussed.
