The intestinal mucosa represents important primary interface with the external environment. The mucosal immunity posses the ability to differentiate between non-pathogenic microbial agents (non-inflammatory immune reaction) and pathogens (inflammatory immune response). The defence mechanisms of intestinal mucosa due to extensive nonadaptive and adaptive immune reactions facilitate both inductive and effector side of immune response. The oral tolerance is dependent on the mucous intestinal immunity and modulates the systemic immune reactivity.

Background: Intestinal transplantation (ITx) represents the only curative option for patients with irreversible intestinal failure. Nevertheless, its rejection rate surpasses that of other solid organ transplants due to the heightened immunological load of the gut. Regulatory T-cells (Tregs) are key players in the induction and maintenance of peripheral tolerance, suggesting their potential involvement in modulating host vs.

Heart failure (HF) is a leading cause of death worldwide. We have shown that pressure overload (PO)-induced inflammatory cell recruitment leads to heart failure in IL-10 knockout (KO) mice. However, it's unclear if PO-induced inflammatory cells also target the gut mucosa, causing gut dysbiosis and leakage.

Introduction: The performance of a high quality esophagogastroduodenoscopy (EGD) is dependent on the mucosal cleanliness. Recently, the Polprep: Effective Assessment of Cleanliness in EGD (PEACE) scale was created to assess the degree of mucosal cleanliness during EGD. The aim of this study was to validate this scoring system in a cohort of international endoscopists.

The pinnatoxins (PnTXs) and portimines, produced by , have been detected in several countries, raising concerns for human health. Although no human poisoning from these toxins has been reported so far, they have been shown to distribute throughout the rodent body after oral administration. Therefore, we investigated the impact of PnTX analogs (PnTX-A, -E, -F, -G, and -H) and portimine (8, 16, and 32 ng/mL) on intestinal barrier integrity and their oral bioavailability using human Caco-2 cell monolayers treated for 2, 6, and 24 h.

Xylooligosaccharides (XOS) ameliorate insulin resistance (IR) in gestational diabetes mellitus (GDM) probably by propagating Akkermansia muciniphila (Akk). This study aimed to investigate the effects and mechanisms of XOS, Akk and combination on IR in GDM mice/pseudo-germ-free (PGF) mice. Female mice were fed with AIN-93 (n = 19) and high fat diet (HFD) (n = 206).
