Mast cells (MCs) are localized in connective tissues and are more numerous near the boundaries between the external environment and the internal milieu including the skin, the respiratory tract, the gastrointestinal tract and the conjunctiva. In the gastrointestinal tract, MCs represent 1-5% of mononuclear cells in the lamina propria of the mucosa and in the submucosa, and they are also found inside the epithelium and deep in the muscle and serosal layers. The gastrointestinal MCs perform their biological functions, releasing mediators, as amines (histamine, serotonin), cytokines, proteases, lipid mediators (leukotrienes, prostaglandins), and heparin. MCs are involved in the pathogenesis of different inflammatory conditions and tumors of the gastrointestinal tract. The use of MCs' tryptase inhibitors or c-KitR tyrosine kinase inhibitors could represent a potential anti-MC therapeutic approach in all the inflammatory and tumor pathological conditions of the digestive tube in which MCs are involved.

Graft-versus-host disease (GVHD) is less common in autologous stem cell transplantation (ASCT) recipients than in allogeneic SCT recipients. However, some cases of severe GVHD, especially involving the gastrointestinal (GI) tract, have been documented. We present a patient with primary central nervous system lymphoma (PCNSL) exhibiting severe GI-GVHD after ASCT with busulfan/thiotepa conditioning.

Despite the WHO recommendations in favor of breastfeeding, most infants receive infant formulas (IFs), which are complex matrices involving numerous ingredients and processing steps. Our aim was to understand the impact of the quality of the protein ingredient in IFs on gut microbiota and physiology, blood metabolites and brain gene expression. Three IFs were produced using whey proteins (WPs) from cheese whey (IF-A) or ideal whey (IFs-C and -D) and caseins, either in a micellar form (IFs-A and -C) or partly in a non-micellar form (IF-D).

Health benefit effects of bioactive compounds depend on their bioavailabilities, which could vary according to factors including food matrix and digestion environment. To understand the "bioaccessible" health benefit of red pitay pulp, the INFOGEST static in vitro simulation of gastrointestinal (GI) digestion model and targeted metabolomics method were applied to unravel the fates of bioactive compounds in the whole food of red pitaya pulp during GI digestion. The antioxidant activity as one of the health benefit indices was also assessed to compare the changes in bioactive properties of red pitaya pulp.

Ulcerative colitis (UC) is a chronic inflammatory bowel condition that significantly impairs patient quality of life and remains incurable. Effective dietary management is crucial for both prevention and treatment. This study investigates the effects and mechanisms of Eurotium cristatum-fermented black tea (FBT) in a dextran sulfate sodium (DSS)-induced UC mouse model using transcriptome sequencing, immunofluorescence, and flow cytometry.

In this study, we developed a double-layer colon-targeted microcapsule. It used the Maillard product of gelatin-isomaltooligosaccharide (GI180) and zein-shellac complex (ZS) as bio-based materials, plant extracts (MPL) and Lactobacillus plantarum JJBYG12 (JJBYG12) were co-encapsulated, endowing them with strong resistance to harsh environments and precise intestinal adhesion and targeting ability. The research results indicated that ZS11 exhibits hydrogen bonding and electrostatic interactions.
