My research interest is the blood-brain barrier (BBB) which regulates molecular traffic across blood and the brain. The BBB is formed by brain capillary endothelium. At CDR, we have established cell culture models using primary brain endothelial cells which allow us to study the BBB function, particularly transport across the BBB. We are using the models to study mechanisms of BBB permeability, including that of the neurotransmitter glutamate. Through several collaborative projects, we are utilizing the models for screening of BBB permeable compounds. We are also looking into alterations of the BBB structure and function in pathological condition.
Current Research Projects:
- The pathophysiology of the BBB in animal model of cerebral hypoperfusion
- Application of in vitro model of the BBB to investigate detailed permeability mechanisms of Mitragyna speciosa (ketum) alkaloids
