Blood Brain Barrier Integrity

The blood brain barrier (BBB) is well-known for its capacity to limit access of the brain to the circulation. Our BBB research projects are focused on the three main areas. First, we are evaluating the peptide hormone ghrelin and VNS as anti-inflammatory strategies that protect from traumatic brain injury (TBI)-induced neurological deficits and breakdown of the BBB. Second, we are examining Ecrg4 as a mediator of microglia activation and neuroepithelial integrity in glioma and penetrating brain injury. Third, we are characterizing the mechanism and preclinical relevance of vascular normalization using genetic models or pharmacological inhibitors of focal adhesion kinase. In combination, these studies provide a integrated approach for the study of BBB integrity to better understand mechanisms that regulate immune and vascular homeostasis.
