Abstract

Our laboratory has focused on the increased activity of an endogenous vascular elastase in the pathobiology of pulmonary hypertension and on the mechanisms by which it is upregulated and by which it orchestrates abnormal remodeling of the vessel wall, specifically the induction of growth factors, the induction of the glycoprotein tenascin, which amplifies the proliferative response, and fibronectin, which is critical to the process of smooth muscle migration in the context of neointimal formation. We explore strategies by which targetting these processes might arrest progression or induce regression of pulmonary vascular disease associated with unexplained pulmonary hypertension.
