Connexin 43 connexon to gap junction transition is regulated by zonula occludens-1

, 2011
Connexin 43 (Cx43) is a gap junction (GJ) protein widely expressed in mammalian tissues that mediates cell-to-cell coupling. Intercellular channels comprising GJ aggregates form from docking of paired connexons, with one each contributed by apposing ...

Toxicity Differences Between Microplastics and Nanoplastics in Organs: From Molecular Mechanisms to Potential Therapeutic Strategies

Med Research, EarlyView.
This review systematically compares the size‐dependent toxicity of microplastics and nanoplastics in the intestine, liver, kidney, lung, and brain. Particle size determines bioavailability, barrier penetration, and injury mechanisms. Because of their small size and high surface reactivity, NPs readily cross the intestinal epithelium and blood–brain ...

Phytochemicals in MASLD: A Focused Review of Gut Microbiome‐Linked Mechanisms

Phytotherapy Research, EarlyView.
ABSTRACT Metabolic dysfunction‐associated steatotic liver disease (MASLD) has emerged as a major global health burden, yet effective pharmacological options remain limited. Recent advances highlight the gut microbiome as a key modulator of liver metabolism, inflammation, and fibrosis, making it a promising therapeutic target.

Epileptiform Activity Induces Vascular Remodeling and Zonula Occludens 1 Downregulation in Organotypic Hippocampal Cultures: Role of VEGF Signaling Pathways

, 2011
International audienceRecent studies suggest that blood-brain barrier (BBB) permeability contributes to epileptogenesis in symptomatic epilepsies. We have previously described angiogenesis, aberrant vascularization, and BBB alteration in drug-refractory ...

Charakterisierung der Struktur, Funktion und Wechselwirkungen der Tight Junction Proteine Occludin und Zonula Occludens 1 [PDF]

, 2009
Die tight junction schränken die Diffusion durch den parazellulären Raum in Epithel- und Endothelzellschichten für viele Moleküle stark ein. Dadurch behindern sie die Aufnahme von wasserlöslichen Medikamenten in das dahinterliegende Gewebe. Zwei Proteine,

Improvement of Lactiplantibacillus plantarum MWFLp-182 on oxidative deficits induced by in 2,2’-azobis(2-methylpropionamidine) dihydrochloride and the relating key gene analysis

Food Science and Human Wellness
Lactiplantibacillus plantarum MWFLp-182 was originally isolated from the feces of long-living elderly individuals in Hezhou city, Guangxi, China. L. plantarum MWFLp-182 showed favorable gastric and intestinal tolerance compared with Lactiplantibacillus ...

The light chains of microtubule-associated proteins MAP1A and MAP1B interact with α1-syntrophin in the central and peripheral nervous system.

PLoS ONE, 2012
Microtubule-associated proteins of the MAP1 family (MAP1A, MAP1B, and MAP1S) share, among other features, a highly conserved COOH-terminal domain approximately 125 amino acids in length.

Human Blood‐Brain Tumor Barrier on a Chip to Investigate Personalized Treatment for Glioblastoma Patients

Small, EarlyView.
A microfluidic model of the glioblastoma (GBM) margin was developed to mimic patient‐specific blood‐brain tumor barrier (BBTB) function and drug response. The platform revealed inter‐patient variability in barrier integrity and drug sensitivity, offering a tool for personalized therapy evaluation in GBM.

Affinity purification and partial characterization of the zonulin/zonula occludens toxin (Zot) receptor from human brain

, 2000
The intercellular tight junctions (TJs) of endothelial cells represent the limiting structure for the permeability of the blood-brain barrier (BBB). Although the BBB has been recognized as being the interface between the bloodstream and the brain, little
