Neurovascular & Blood–Brain Barrier

From Model Modeling to Functional & Mechanistic Insight

Integrated research solutions for establishing physiologically relevant BBB models, assessing barrier function, characterizing neurovascular biology, and decoding disease-associated BBB dysfunction.

The blood–brain barrier (BBB) is a dynamic neurovascular interface that regulates molecular transport between the circulation and the central nervous system. BBB properties are shaped by coordinated interactions among brain endothelial cells, pericytes, astrocytes, neurons, microglia, and the vascular extracellular matrix.

Understanding BBB biology therefore requires an integrated approach that connects model establishment, functional assessment, molecular validation, neurovascular unit (NVU) characterization, disease mechanisms, and brain-targeted delivery.

Research focus

BBB development | Barrier integrity | Neurovascular unit | Disease modeling | Therapeutic evaluation

02 | Molecular Validation

Validate BBB Identity, Integrity and Function

A focused antibody portfolio for molecular characterization of the blood–brain barrier (BBB)—from endothelial identity and junctional organization to transporter expression and barrier function.

Endothelial Identity

Define BBB endothelial cell identity and characterize the vascular phenotype of in vitro and in vivo BBB models.

Junctional Integrity

Assess tight-junction organization, continuity and localization—key molecular features underlying BBB paracellular barrier function.

Transporter & Efflux

Characterize the selective transport and drug-efflux properties that distinguish the BBB from peripheral vascular barriers.

03 | Neurovascular Unit Characterization

Define the cellular architecture and microenvironment of the BBB

BBB function is not determined by endothelial cells alone. The neurovascular unit (NVU) integrates vascular, glial, neuronal, and extracellular-matrix components that collectively shape BBB integrity and neurovascular function.

Multicellular BBB models provide a functional context for studying endothelial–pericyte–astrocyte interactions within the neurovascular unit. (https://www.pharmacocell.co.jp/en/)

Key NVU Components

From Cellular Architecture to BBB Pathology

From cellular identity and neurovascular unit (NVU) organization to cell–cell/ECM interactions, BBB structural integrity, neurovascular function, and disease-associated remodeling, a multidimensional approach enables comprehensive characterization of BBB architecture, function, and pathological changes.

SPATIAL NVU PROFILING

Multiplex IF/IHC · Spatial Imaging · Cellular Neighborhood Analysis

Resolve vascular cells, glial states, neuronal populations, pathological features, and extracellular-matrix organization within their native spatial context.

04 | BBB Dysfunction Research

From Barrier Disruption to Molecular Mechanisms

BBB dysfunction results from interconnected changes in inflammatory signaling, oxidative stress, hypoxia, endothelial injury, junctional disruption, and extracellular-matrix remodeling.

A multidimensional profiling strategy enables researchers to connect pathological signaling with changes in barrier integrity, permeability, transport, and neurovascular function.

05 | BBB Transport & Targeted Delivery

From BBB Permeability to Brain-Targeted Delivery

The selective permeability of the BBB presents a major challenge for CNS drug delivery. Understanding transport pathways, receptor-mediated processes, efflux mechanisms, and barrier integrity provides a foundation for investigating brain-targeted delivery strategies.

RVG is a rabies virus glycoprotein-derived targeting peptide that has been investigated for interaction with nicotinic acetylcholine receptors (nAChRs) and their potential role in CNS-targeting strategies.

RVG Lipid-Anchor Kit

A Tool for Neural-Targeted Exosome Engineering

RVG Lipid-Anchor Kit enables efficient exosome surface engineering through a PEG–cholesterol-conjugated FAM–RVG targeting peptide. The cholesterol moiety integrates into the exosomal phospholipid membrane, anchoring RVG onto the exosome surface and facilitating BBB transport, neuronal targeting, and brain-directed delivery studies. This convenient lipid-anchor strategy provides a practical tool for engineering and evaluating targeted exosome delivery systems.
