Cytoskeletal Regulation and Function in Endothelial Biology
Grants: K08 National Institutes of Health / NHLBI – Protein Regulation and Cytoskeletal Dynamics of Pulmonary Endothelial Barrier Function.
Presentations: CARMIL1 Regulates Pulmonary Endothelial Barrier Function. P Belvitch, R Demeritte, JGN Garcia, SM Dudek. Accepted for presentation at ATS 2020 in Philadelphia.
My lab investigates the biology of pulmonary vascular leak and its role in causing the acute respiratory distress syndrome (ARDS), a devastating clinical condition characterized by flooding of the normally air filled alveolar space with protein rich edema fluid. The pathologic mechanisms causing edema formation are poorly understood and there remains no specific treatment. We study the problem with a focus on pulmonary endothelial barrier function which is lost during ARDS. Endothelial cytoskeletal structure and dynamics are critical to the formation, maintenance and repair of barrier integrity. Many different interacting signaling molecules, kinases and structural proteins are responsible for changes in cell membrane shape and interactions with neighboring cells to ultimately determine endothelial permeability. The lab employs numerous in vitro and in vivo models and techniques to better understand the endothelial processes underlying vascular leak with the goal of identifying potential therapeutic targets to lessen the burden of ARDS.

INSTRUCTIONS: In order to add a sidebar anchor:
- Duplicate the existing item, listed as a 1/6 text field. (Or create a 1/6 column and add a text field, modify the class so it’s exactly “additionalAnchor”).
- Modify the text field inside the 1/6 column. Inside there, modify the HYPERLINK so that it would go to a corresponding section with a “#” in front of it. (Example, we have a “chief” section on the page, then it would make sense to have the hyperlink go to “#chief”)
- Then change the hyperlink TEXT to a appropriate label.
- IMPORTANT: If not done already, go into that CONTAINER that corresponds to your anchor (i.e. Meet The Chiefs), and add an ID matching the anchor’s HYPERLINK WITHOUT the “#”, i.e. “chief”.
- (If using side bar widget box, then there’s a saved copy of a widget box COLUMN, grab it in the column library, it should 1/6 of a length of a column.)
NOTE: Order added to the sidebar is from last to first.
