Area of Science:

• Neuroscience
• Biomedical Engineering
• Pharmacology

Background:

• The blood-brain barrier (BBB) is crucial for central nervous system (CNS) protection against harmful substances.
• Neurological disorders necessitate realistic in vitro models for effective research and treatment development.
• Existing models often lack the dynamic physiological conditions of the in vivo BBB.

Purpose of the Study:

• To introduce advanced in vitro blood-brain barrier (BBB) models for neurological disorder research.
