Investigating how the heart and the brain affect our health
Our Mission
The Aging, Brain, Circulation (ABC) Laboratory aims to understand how the brain and blood circulation affect health and disease. We study the relationship between brain blood flow regulation, brain structure changes, and the outcomes of injury to the brain or circulatory system. We now understand markers of brain blood flow regulation, which can be used to predict brain and blood circulation diseases.

McDonald Cell Stem Cell 2018
Here we studied the molecular mechanisms of endothelial cell regeneration in adult vessels. Using a model of aortic injury, we found that regeneration occurs at the edges of the wounded area with equal strength and regardless of flow direction. Through a robust proliferative response, the wound closes by efforts of a rapidly dividing cell population that expresses Atf3.
Mack Nat. Comm. 2017
Here we showed that Notch1 is expressed at high levels in adult large arteries with polarized distribution downstream flow direction. Reversion of flow direction promotes relocation of Notch1 to the other pole of the cells, indicating that Notch is a mechanosensor. Inactivation of Noth1 affects the integrity of endothelial barrier and promotes endothelial proliferation.
