Development of a microengineered human blood-brain barrier model WITH 3D ASTROCYTIC NETWORK

 

The blood-brain barrier (BBB), a unique vascular border in the central nervous system (CNS), has a highly selective barrier function that prevents unwanted substances from entering the brain. To deliver drugs into the brain, CNS delivery systems have been widely explored to cross the BBB. However, the lack of experimental models that can precisely analyze the interactions between the BBB and delivery platforms restricts successful clinical translation of CNS therapeutics. Despite valuable contribution of animal models to drug discovery, it remains difficult to conduct mechanistic studies on the barrier function and interactions with drugs at molecular and cellular levels. One innovative approach to addressing this challenge is to develop an in vitro model that mimics the essential physiological structure and function of the human BBB and that allows quantitative analysis of drug transport across the barrier in a controlled manner. The main focus of this thesis is on development of a microengineered human BBB model which reconstitutes the key structure and function of the human BBB and enables 3D capturing of nanoparticle distribution at tissue and cellular levels to demonstrate the mechanisms of cellular uptakes and BBB penetration. This BBB model may present a complementary in vitro model to animal models for prescreening drug candidates for the treatment of CNS diseases.
