Mechanisms For Extracellular Matrix-Dependent Blood-Brain Barrier Dysfunction, Brian Adam Hoettels

Boise State University Theses and Dissertations

Dysfunction of the blood vessels that form the blood-brain barrier (BBB) is observed across various neurological disorders, including multiple sclerosis (MS). As barrier loss culminates in neuronal dysfunction and degeneration, a better understanding of the mechanisms underlying BBB dysfunction is needed.

Tight junctions are multiprotein complexes maintained by the endothelial cells lining the inner blood vessel wall to seal the intercellular space, and their disruption impairs BBB function. In my first chapter, I focus on how tight junctions are altered in CNS inflammatory demyelinating diseases (CNS-IDDs) like MS as BBB dysfunction is one of the earliest known stages in …
