Summary: The blood-brain barrier is a highly selective cellular monolayer unique to the central nervous system microvasculature, mediating communication with the body by regulating the passage of molecules. Recent studies have highlighted the importance of intermediate filaments in the formation and function of cell-cell junctions, particularly vimentin in endothelial cells. Intermediate filaments may have been overlooked as key targets in regulating blood-brain barrier permeability in health and disease.

Summary: In experimental autoimmune encephalomyelitis (EAE), claudin-5 (CLN-5) was found on leukocytes in the blood and central nervous system (CNS), potentially facilitating leukocyte transendothelial migration (TEM) across the blood-brain barrier. Flow cytometry analysis showed CLN-5(+) populations among various leukocyte subtypes, with higher levels in CNS tissue than in blood, suggesting preferential access to the CNS. This novel mechanism may guide leukocytes to sites for diapedesis across the BBB.

Summary: Due to their biocompatibility and high cargo capability, graphene-based materials are considered as an ideal brain delivery system. In this study, we used two in vitro models to investigate the interactions between graphene oxide and few-layer graphene with the blood-brain barrier. Our results show that the two graphene materials have good biocompatibility and do not significantly affect the integrity and functionality of the barrier, but their translocation across the barrier is rare.

Summary: The study shows that Cldn3 and occludin play a protective role in the stroke by maintaining the integrity of TJ and BBB, but also contribute to the development of edema and infarction.

Summary: This study investigates a novel noninvasive sound conditioning strategy to enhance the permeability of the blood-labyrinth-barrier (BLB) and facilitate drug delivery into the inner ear. The results suggest that the key gene Rab13 plays an inhibitory role in controlling the tight junction and cellular permeability, while transcellular trafficking has little impact. These findings have important implications for clinical medications for hearing loss.

Summary: This review provides an overview of the three barriers formed between the cerebrovascular and the brain parenchyma, focusing on the composition and function of the blood-brain barrier (BBB). It discusses the limitations of the BBB for drug delivery and explores potential strategies for improving CNS drug delivery.

Summary: The study investigated the impact of GMH on the BBB using a rat model, showing that GMH causes temporary dysfunction in the BBB that normalizes within 5 days. Tight-junction proteins were identified as potential biomarkers for GMH.

Summary: The blood-brain barrier is an important protective barrier of the central nervous system that prevents harmful substances from entering. Dysfunction of the blood-brain barrier is an early sign of nervous system diseases. Recent studies have focused on ferroptosis, a novel cell death mode caused by iron-mediated lipid peroxidation accumulation, and its potential role in blood-brain barrier dysfunction. Understanding the relationship between ferroptosis and blood-brain barrier dysfunction may lead to new treatment targets for brain diseases.

Summary: Mep1b is a novel regulator of tight junction composition and blood-brain barrier integrity in brain endothelium. Knock-out of Mep1b in mice showed increased expression of TJ proteins and improved TEER, suggesting Mep1b plays a role in BBB tightness regulation.

Summary: Aging-induced alterations to the blood-brain barrier are increasingly recognized as a primary event in chronic neurological disorders; development of nanoparticles targeting regions of increased claudin-1 expression shows promise for treating these diseases; claudin-1 plays a role in reducing BBB integrity during aging, and nanoparticles can be used to actively target altered claudin-1 expression for therapeutic delivery.

Summary: This study focuses on organs with continuous endothelium and explores the structural and functional characteristics of the EC barrier. By integrating multiple single-cell RNA-seq datasets, it is found that Claudin5 has different expression patterns and roles in different tissues, playing an important role in the integrity of the EC barrier.

Summary: Ischemic stroke is a major cause of morbidity and mortality globally. Despite positive results in preclinical studies, only one compound has advanced to Phase III clinical trial evaluation. This may be due to the neglect of transport mechanisms at the blood-brain barrier and neurovascular unit. This review highlights the role of BBB transporters in drug delivery and their expression in different brain cell types.

Summary: The neurovascular unit (NVU) is a group of cells that establish the blood-brain barrier and coordinate cerebral blood flow. Dysfunction of the NVU is common in diseases like ischemic stroke. This study used confocal microscopy to simultaneously investigate associations between different cell types in healthy and ischemic brain tissue, providing a better understanding of NVU function and pathology.
