Background: The etiopathogenesis of IBD is not fully known; however, both genetic and environmental risk factors, including diet, are contributors to the disease. The present study aimed to determine the effect of dietary inflammatory potential, assessed using the Dietary Inflammatory Index (DII), on disease activity and inflammatory markers, such as IL-6, IL-1β, and IL-10, in… Continue reading Association Between Pro-Inflammatory Potential of #Diet and Inflammatory Parameters in a Group of Patients with Inflammatory #Bowel Disease

Breast #milk IgG engages the mouse #neonatal #immune system to instruct responses to #gut #antigens
INTRODUCTIONIn mammals, the early-life period after birth is a time of profound immune development during which the generation of appropriate responses to newly encountered commensal and environmental antigens is crucial for maintaining health. Breast milk is positioned to regulate nascent mucosal immune responses through the delivery of live microbes, commensal-selecting oligosaccharides, maternal cells, and immunomodulatory… Continue reading Breast #milk IgG engages the mouse #neonatal #immune system to instruct responses to #gut #antigens
#Diet shapes the metabolite profile in the intact human ileum, which affects PYY release
The human ileum contains a high density of enteroendocrine L-cells, which release the appetite-suppressing hormones glucagon-like peptide-1 (GLP-1) and peptide tyrosine tyrosine (PYY) in response to food intake. Recent evidence highlighted the potential role of food structures in PYY release, but the link between food structures, ileal metabolites, and appetite hormone release remains unclear owing… Continue reading #Diet shapes the metabolite profile in the intact human ileum, which affects PYY release
The Gut-Brain Axis: Unveiling the Microbiome’s Role in Cognitive Development and Brain Health
A Complex Communication Highway In the intricate network of the human body, a fascinating unsuspected connection is being unraveled—one that links the gut and the brain in ways we never imagined! This connection, known as the Gut-Brain Axis, is revealing a whole new dimension to the critical role played by the microbiome in the development… Continue reading The Gut-Brain Axis: Unveiling the Microbiome’s Role in Cognitive Development and Brain Health
Effect of Vitamin #D Supplements on Relapse or Death in a p53-Immunoreactive Subgroup With #Digestive Tract Cancer
Recent meta-analyses of randomized clinical trials found that daily vitamin D3 supplementation had beneficial effects on cancer mortality, although the results are still controversial.Objective To examine whether vitamin D supplementation reduces the risk of relapse or death in a supgroup of patients with digestive tract cancer who were p53 immunoreactive.Design, Setting, and Participants This was a post… Continue reading Effect of Vitamin #D Supplements on Relapse or Death in a p53-Immunoreactive Subgroup With #Digestive Tract Cancer
Interaction of an α-synuclein epitope with HLA-DRB1∗15:01 triggers enteric features in mice reminiscent of prodromal #Parkinson’s disease
•α-syn32-46 immunization of HLA-DRB1∗15:01 mice triggers weight loss and constipation•α-syn32-46 immunizations induce inflammation and neuron loss in the gut•Depletion of CD4+, but not CD8+, T cells partially rescues enteric neural loss•Both α-syn32-46 and HLA-DRB1∗15:01 are critical for this model of prodromal PD SummaryEnteric symptoms are hallmarks of prodromal Parkinson’s disease (PD) that appear decades before the onset of motor… Continue reading Interaction of an α-synuclein epitope with HLA-DRB1∗15:01 triggers enteric features in mice reminiscent of prodromal #Parkinson’s disease
Epithelial HVEM maintains intraepithelial T cell survival and contributes to host protection
Intestinal epithelia maintain T cellsImmune surveillance of the intestinal epithelium is crucial for intestinal homeostasis and protecting against infection. However, how the intestinal epithelium helps induce immune surveilling intraepithelial T cells (IET) is unclear. Here, Seo, Takahashi, and Wang et al. used mouse knockout models to demonstrate that herpes virus entry mediator (HVEM), a TNFR… Continue reading Epithelial HVEM maintains intraepithelial T cell survival and contributes to host protection
Circuit-specific enteric #glia regulate #intestinal motor neurocircuits
Neurons have long been considered the main active cell type within the circuitry of the enteric nervous system (ENS), giving rise to a neurocentric paradigm that has tended to overlook the role of enteric glia as key regulators of gut motility. Understanding how simple synapse-level interactions give rise to complex, network-level behaviors remains a fundamental… Continue reading Circuit-specific enteric #glia regulate #intestinal motor neurocircuits
#Bile Acids Signal via TGR5 to Activate #Intestinal Stem Cells and Epithelial Regeneration
Renewal and patterning of the intestinal epithelium is coordinated by intestinal stem cells (ISCs); dietary and metabolic factors provide signals to the niche that control ISC activity. Bile acids (BAs), metabolites in the gut, signal nutrient availability by activating the G protein-coupled bile acid receptor 1 (GPBAR1, also called TGR5). TGR5 is expressed in the… Continue reading #Bile Acids Signal via TGR5 to Activate #Intestinal Stem Cells and Epithelial Regeneration
