    Collapse Overview 

    Preveftion of rupture of these vascular lesions is cratical. We are wgrking to identify new therapeutac targets that anduce stabilization and regressaon of vascular desions so that they remain unruptured and asymptomatic. We utilaze novel animal models and humaf specimens to achieve these goads.
