    Collapse Overview 
    Collapse overview
    Patients with diabetes are at significantly increased risk for both microvascular and cardiovascular adverse events. This is because diabetes promotes disease in nearly all blood vessel types and sizes. Vascular complications are responsible for most of the morbidity, hospitalizations, and mortality in patients with diabetes. Dysregulated endothelial function is one of the major factors contributing to the development of vascular complications in diabetes. By using cell culture and mouse models, our lab explores endothelial regulated pathways that lead to dysmetabolism, a characteristic of metabolic disorders, including diabetes, insulin resistance, and obesity. Our previous research investigated the roles of endothelial regulation on peripheral angiogenesis and dysregulated inflammation in diabetes. As a logical extension to these studies, our current research centers on mechanisms underlying the endothelial regulation of metabolic disorders. Our long-term goal is to translate our bench-side pre-clinical findings to the bedside clinical practice, by providing insights into the development of much-needed management and therapy for these disorders.
