The role of intestinal permeability (IP) markers among children and adults with food allergies is not fully understood, and the identification of biological indicators/markers that predict growth retardation in children with allergic diseases and atopy has not been well explained. Studies have shown that patients with atopic diseases respond abnormally to food allergens. Accordingly, differences in the types of immune complexes formed in response to antigen challenges are significant, which seems to underlie the systemic signs of the food allergy. Increased intestinal permeability over the course of a food allergy allows allergens to penetrate through the intestinal barrier and stimulate the submucosal immune system. Additionally, the release of cytokines and inflammatory mediators enhances the degradation of the epithelial barrier and leads to an improper cycle, resulting in increased intestinal permeability. Several studies have also demonstrated increased permeability of the epithelial cells in those afflicted with atopic eczema and bronchial asthma. Ongoing research is aimed at finding various indicators to assess IP in patients with atopic diseases.

An effective intervention for obesity without side effects is needed. Chrysanthemum may be the preferred choice due to its influence in the improvement of glycolipid metabolism. This study assessed the efficacy of chrysanthemum and its flavonoids in mitigating high-fat diet (HFD) induced obesity, focusing on the integrity of the intestinal barrier, inflammation, and gut microbiota.

Background And Aims: Protein tyrosine phosphatase non-receptor type 23 (PTPN23) regulates the internalization of growth factor receptors such as the epithelial growth factor receptor (EGFR). Given the crucial function of such receptors in intestinal epithelial cells (IECs), we assessed the involvement of PTPN23 in intestinal homeostasis and epithelial proliferation.
Methods: We generated mouse models with constitutive (PTPN23fl/flVilCre+/-) or inducible (PTPN23fl/flVilCreERT+/-) deletion of PTPN23 in IEC.

Purpose: C9orf72 deficiency contributes to severe inflammation in mice. Ulcerative colitis (UC) is a chronic inflammatory disorder with the shortage of clinical success. However, whether C9orf72 is involved in the progression of UC is not fully understood.

Background And Aims: Probe-based confocal endomicroscopy (pCLE) allows real-time microscopic visualization of the intestinal mucosa surface layers. Despite remission achieved through anti-tumor necrosis factor or vedolizumab therapy, anomalies in the intestinal epithelial barrier are observed in inflammatory bowel disease (IBD) patients. Our study aimed to assess these abnormalities in non-IBD individuals and compare them with IBD patients in endoscopic remission to identify the associated factors.

Telocytes, a novel mesenchymal cell population, are characterized by their distinctive long and slender projections known as telopodes and have garnered significant interest since their formal introduction to the literature in 2010. These cells have been identified in various tissues, including the gastrointestinal (GI) tract, where they are suggested to play important roles in maintaining structural integrity, immune modulation, and barrier function. Inflammatory bowel diseases (IBD), which include Crohn's disease (CD) and ulcerative colitis (UC), are characterized by chronic inflammation and fibrosis.
