Vascular and Sphingolipid Biology

Dr. Di Lorenzo’s laboratory is interested in two major area of research: one is to define the molecular mechanisms by which endothelial nitric oxide synthase (eNOS)-derived NO controls the endothelial barrier functions to the passage of plasma molecules and inflammatory cells.Another area of research focuses on the role of Nogo-B, belonging to the Reticulon-4 family of proteins expressed in the ER, in vascular function regulation and in cardiac hypertrophy development.

Active Projects

To study the role of eNOS in vascular permeability and inflammatory cell recruitment to the site of inflammation.
To investigate the role of Nogo-B in vascular function and cardiac hypertrophy.
