Investigators in the Lakshmi Santhanam Lab examine the fundamental mechanisms behind cardiovasc...ular disease. They are particularly interested in better understanding how nitric oxide-mediated S-nitrosylation (a post-translational protein modification) impacts protein function and trafficking in the vasculature as well as how this relationship influences matrix remodeling and vascular stiffening. view moreResearch Areas: vasculature trafficking, protein trafficking, S-nitrosation, protein function, nitric oxide, matrix remodeling, vascular stiffness, cardiovascular diseases

The Shanthini Sockanathan Laboratory uses the developing spinal cord as our major paradigm to d...efine the mechanisms that maintain an undifferentiated progenitor state and the molecular pathways that trigger their differentiation into neurons and glia. The major focus of the lab is the study of a new family of six-transmembrane proteins (6-TM GDEs) that play key roles in regulating neuronal and glial differentiation in the spinal cord. We recently discovered that the 6-TM GDEs release GPI-anchored proteins from the cell surface through cleavage of the GPI-anchor. This discovery identifies 6-TM GDEs as the first vertebrate membrane bound GPI-cleaving enzymes that work at the cell surface to regulate GPI-anchored protein function. Current work in the lab involves defining how the 6-TM GDEs regulate cellular signaling events that control neuronal and glial differentiation and function, with a major focus on how GDE dysfunction relates to the onset and progression of disease. To solve these questions, we use an integrated approach that includes in vivo models, imaging, molecular biology, biochemistry, developmental biology, genetics and behavior. view moreResearch Areas: glia, biochemistry, neurons, imaging, developmental biology, genomics, spinal cord, behavior, molecular biology
