Modulazione fisiologica della permeabilità intestinale e assorbimento di molecole idrofiliche [PDF]

, 1983
2009/2010La permeabilità intestinale è regolata dalle tight junctions (TJ) che costituiscono la barriera gastrointestinale e che sono soggette a regolazione fisiologica. Dati di letteratura dimostrano che digiuno e malnutrizione agiscono su tale barriera

immunoHuMiX: A personalizable gut‐on‐chip model for unraveling human microbiome–immune interactions

VIEW, EarlyView.
The study introduces a personalized gut model that brings together human immune cells and intestinal cells to better mimic how the body interacts with microbes. This system successfully maintained both human cells and a 17‐strain probiotic community, showing consistent immune responses across different donors.

Tight junction proteins in glial tumors development and progression

Frontiers in Cellular Neuroscience
Tight junctions form a paracellular barrier in epithelial and endothelial cells, and they regulate the diffusion of fluids, molecules, and the penetration of cells across tissue compartments.

Modulation of KATP channels by diazoxide preserves mitochondrial function and barrier integrity under staurosporine‐induced epithelial stress

British Journal of Pharmacology, EarlyView.
Background and Purpose Intestinal barrier dysfunction caused by mitochondrial stress, oxidative damage and apoptosis, are hallmarks of dysbiosis‐associated gastrointestinal (GI) disorders. Staurosporine causes downstream features of dysbiosis‐induced epithelial damage.

A guide to the types, structures, and multifaceted functions of matrix metalloproteinases in cancer

The FEBS Journal, EarlyView.
Matrix metalloproteinases (MMPs) orchestrate cancer progression and metastasis through proteolytic and non‐proteolytic actions. By remodeling the tumor microenvironment, enhancing growth factor availability, and modulating cell behavior, MMPs promote proliferation, migration or invasion, and epithelial‐to‐mesenchymal transition. Alongside extracellular

High prevalence of loss of Claudin‐18 expression in invasive non‐mucinous lung adenocarcinoma: Potential diagnostic implications in routine practice

Histopathology, EarlyView.
Loss of Claudin‐18 (Cldn18) expression is a frequent and specific feature of non‐mucinous lung adenocarcinoma (NM‐LUAD). Cldn18 immunohistochemistry may serve as an ancillary tool for distinguishing malignant from non‐neoplastic alveolar epithelium, as well as for differentiating NM‐LUADs with mucin production from M‐LUADs, particularly in small or ...

Inflammatory and Immunological Basis of Periodontal Diseases

Journal of Periodontal Research, EarlyView.
The periodontal lesion emerges as an evolving immunological battlefield, where host–microbiome interactions, dysregulated immune responses, fragile resolution mechanisms, and inflammophilic dysbiosis converge to shift the balance from homeostasis to unrestrained tissue destruction.

Metabolic Reprogramming and GM‐CSF Secretion in Areca Nut‐Activated Fibroblasts Drive Oral Precancer Progression

Oral Diseases, EarlyView.
ABSTRACT Objective Oral cancer, with a rising global incidence and poor prognosis, is associated with areca nut use in South and Southeast Asia. In this study, we addressed the effects of areca nut extract (ANE) on oral carcinogenesis by modulating fibroblast behavior in oral tissue.

Porphyromonas gingivalis GroEL accelerates abdominal aortic aneurysm formation by matrix metalloproteinase‐2 SUMOylation in vascular smooth muscle cells: A novel finding for the activation of MMP‐2

Molecular Oral Microbiology, EarlyView.
Abstract Infection is a known cause of abdominal aortic aneurysm (AAA), and matrix metalloproteases‐2 (MMP‐2) secreted by vascular smooth muscle cells (SMCs) plays a key role in the structural disruption of the middle layer of the arteries during AAA progression.
