What human blood-brain barrier models can tell us about BBB function and drug discovery?

Expert Opinion on Drug Discovery
Lino Ferreira

Abstract

Introduction: Human in vitro blood-brain barrier (BBB) models could be important tools for studying BBB development, maintenance and regulation. However, our capacity to obtain information from these models is still limited in part because only in recent years have (i) these models been derived from non-brain cell sources (e.g. stem cells), (ii) microfluidic systems been developed to recapitulate aspects of BBB physiology and (iii) new insights into the molecular and cellular mechanisms of BBB diseases (e.g. Huntington´s, Allan-Herndon-Dudley Syndrome) been described. Area covered: This article reviews the technological advances in the derivation of human cells from the neurovascular unit using stem cells and the creation of personalized BBB models generated from patients with neurodegenerative diseases. It also reviews the scientific advances generated from in vitro BBB models. Expert opinion: The recent technological advances in the derivation of human cells from the neurovascular unit from stem cells as well as in the generation of BBB-on-a-chip that recapitulate in vitro part of the BBB physiology are significant to generate more robust BBB models; however, a considerable effort is still needed to validate the potential of ...Continue Reading

Blood Brain Barrier

The blood brain barrier is a border that separates blood from cerebrospinal fluid. Discover the latest search on this highly selective semipermeable membrane here.

Blood Brain Barrier Regulation in Health & Disease

The blood brain barrier is essential in regulating the movement of molecules and substances in and out of the brain. Disruption to the blood brain barrier and changes in permeability allow pathogens and inflammatory molecules to cross the barrier and may play a part in the pathogenesis of neurodegenerative disorders. Here is the latest research in this field.

Blood Brain Barrier Chips

The blood brain barrier (BBB) is comprised of endothelial cells that regulate the influx and outflux of plasma concentrations. Lab-on-a-chip devices allow scientists to model diseases and mechanisms such as the passage of therapeutic antibodies across the BBB. Discover the latest research on BBB chips here.
