Reversibly unlocking the blood–brain barrier: A study on microtubule dynamics modulation using gold nanoparticle-modified reduced graphene oxide

Acta Pharmaceutica Sinica B
The blood–brain barrier (BBB) is a crucial biological interface between the central nervous system and circulation, playing a key role in maintaining the brain's homeostasis and function, but presenting a challenge for drug delivery.

Mesoporous Silica Nanoparticles‐Based Formulations for Enhanced Oral Delivery of Peptide Drugs: A Case Study on Insulin

Small, EarlyView.
This work explores the tailored functionalization of mesoporous silica nanoparticles (MSN) to improve the oral delivery of insulin, as a case study. Insulin confinement within silica mesopores increased drug solubility, and co‐formulation with succinylated β‐lactoglobulin yielded pH‐responsive tablets that limited gastric release and proteolysis, while

Blood-brain barrier tight junction permeability and ischemic stroke

Neurobiology of Disease, 2008
The blood-brain barrier (BBB) is formed by the endothelial cells of cerebral microvessels, providing a dynamic interface between the peripheral circulation and the central nervous system.

secCl is a cys-loop ion channel necessary for the chloride conductance that mediates hormone-induced fluid secretion in Drosophila [PDF]

, 2019
Organisms use circulating diuretic hormones to control water balance (osmolarity), thereby avoiding dehydration and managing excretion of waste products.

The Integrin β1 Subunit Regulates Paracellular Permeability of Kidney Proximal Tubule Cells*

Journal of Biological Chemistry, 2014
Background: Proximal tubule kidney epithelial cells differentiate into a “loose” epithelium by unknown mechanisms. Results: Deleting integrin β1 converts proximal tubule cells from a “loose” to a “tight” epithelium.

Brain Pericytes and Wnt/β‐Catenin Signaling Induce Functional Blood–Brain Barrier Phenotype in Human iPSC‐Derived Model

Small Methods, EarlyView.
This study shows that human iPSC‐derived endothelial cells acquire a functional blood–brain barrier phenotype when co‐cultured with brain pericytes and stimulated with CHIR‐99021, a Wnt/β‐catenin activator. This model recapitulates key barrier properties, inflammatory responses, and transcriptomic features of the native human BBB, offering new ...

Probing the Action of Permeation Enhancers Sodium Cholate and N-dodecyl-β-D-maltoside in a Porcine Jejunal Mucosal Explant System

Pharmaceutics, 2018
The small intestinal epithelium constitutes a major permeability barrier for the oral administration of therapeutic drugs with poor bioavailability, and permeation enhancers (PEs) are required to increase the paracellular and/or transcellular uptake of ...

PPARγ agonist-loaded PLGA -PEG nanocarriers as a potential treatment for Alzheimer’s disease: in vitro and in vivo studies [PDF]

, 2018
Objective: The first aim of this study was to develop a nanocarrier that could transport the peroxisome proliferator-activated receptor agonist, pioglitazone (PGZ) across brain endothelium and examine the mechanism of nanoparticle transcytosis.

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.
