Microphysiological Blood-Brain Barrier Systems for Disease Modeling and Drug Development

Area of Science:

• Neuroscience
• Biotechnology
• Pharmacology

Background:

• The blood-brain barrier (BBB) tightly regulates brain microenvironment, limiting therapeutic access for neurological disorders.
• Existing animal and in vitro models fail to accurately replicate the human BBB, contributing to clinical trial failures.
• Organs-on-chips represent a novel approach to create more physiologically relevant BBB models.

Purpose of the Study:

• To review innovative methods for creating blood-brain barrier-on-chips (BBBs-on-chips).
• To explore the application of BBBs-on-chips in modeling neurological disorders and assessing therapeutic efficacy.
• To discuss the use of BBBs-on-chips in drug delivery studies and multiorgan platform integration.

Main Methods:

• Utilizing microfluidic platforms to apply physiological stressors on cultured cells.
• Developing in vitro and ex vivo models that mimic the human BBB structure and function.
• Integrating brain organs-on-chips with other organ models to simulate organ crosstalk.

Main Results:

• BBBs-on-chips demonstrate enhanced physiological accuracy compared to traditional in vitro models.
• These models show potential for improved prediction of therapeutic efficacy in neurological diseases.
• The technology facilitates detailed studies on drug delivery across the BBB.

Conclusions:

• BBBs-on-chips offer a promising platform for advancing neurological drug discovery and development.
• This technology can overcome limitations of previous models, leading to more successful clinical trials.
• Future research directions include multiorgan system integration for comprehensive disease modeling.
