Dr. Georg Hilfenhaus, post-doctoral fellow at the Arispe Lab, and collaborators (including 4 undergraduate trainees of the Lab: Dai Nguyen, Jonathan Freshman, Divya Prajapati and Dana Song) have a newly accepted paper in JCB showing Vav3, a GEF that regulates the cytoskeleton, is a critical regulator of barrier that is expressed in capillaries but is absent from large vessel endothelium.
