Research Overview

In my laboratory we have a long standing interest in understanding the role of cerebral blood vessels and blood-brain barrier (BBB) in pathogenesis of neurodegenerative disorders such as Alzheimer’s disease (AD) and more recently amytrophic lateral sclerosis (ALS), as foundations for development of new therapies for AD and related neurodegenerative disorders as well as stroke. My research team is working on the cellular and molecular mechanisms in blood vessels and the neurovascular unit causing BBB disruption which leads to neuronal dysfunction and degenerative changes using models of AD and pericyte-deficient rodents as well as analysis of human brain. Our discoveries contributed to the development of clinical trials based on amyloid-beta clearance in AD patients, and a new therapeutic approach for stroke based on activated protein C mutant which has been initiated in August 2012.
