Diabetes Complications Program

Our Diabetes Complications Program Research Areas
Diabetes is a persistent condition affecting many millions of people in the U.S. and worldwide. With good care and commitment, diabetes can be well managed. Our program covers cardiovascular complications, kidney complications, and eye complications of type 1 and type 2 diabetes. The interactive and collaborative nature of our research team allows us to discover biomarkers and treatment and prevention strategies that are effective in targeting several diabetes complications simultaneously.

Preventing cardiovascular complications of diabetes
We are researching multiple areas with the goal of preventing cardiovascular complications of diabetes, such as heart attack and stroke. One of our interactive teams is investigating the possibility of improving lipid levels and inhibiting low-grade inflammation often associated with diabetes in order to prevent atherosclerosis, the leading cause of heart attack and stroke. Other members of the program work on discovering biomarkers and improved imaging techniques, so that people at increased risk of cardiovascular complications can be identified and prevention strategies can be initiated based on the particular risk factors present. We also research new approaches to heal hearts once damaged by a heart attack. Our research covers both the heart and blood vessels affected by diabetes.

Preventing kidney complications of diabetes
The goal of our research is to prevent kidney complications of type 1 and type 2 diabetes, because kidney complications can lead not only to loss of kidney function but can also increase the risk of developing cardiovascular complications. We are discovering biomarkers of diabetic kidney disease, so that kidney complications can be prevented. A particular area of interest is the use of compositional changes of lipoproteins as biomarkers of increased risk of kidney complications. Lipoprotein composition is carefully mapped by mass spectrometry after a simple blood draw.

Preventing eye complications of diabetes
New technologies and treatment and prevention pathways for eye complications associated with diabetes are investigated by several members of our research team. Novel technologies involve improved imaging of the eye and its blood supply. Mechanistic studies are carried out to identify new treatment options and new avenues to prevent diabetic eye complications.

My team and I have focused on molecular biology and translational research of fortilin, a multifunctional molecule. Fortilin is known to protect β-cells against stress and allow them to expand as insulin requirement increases due to either weight gain or growth. In addition, fortilin drives macrophages to take on oxidized LDL to become foam cells. My lab is the first to report that fortilin facilitates atherosclerosis. We have condition-ready fortilin KO mice in stock in my laboratory and look forward to collaborating with the distinguished faculty in the Institute.

Dr. Chun Yuan, Professor in Radiology, and I co-direct the Vascular Imaging Laboratory at South Lake Union, and we have had a 20-year history of collaboration focused on the development and application of novel magnetic resonance imaging (MRI) techniques for characterization of cerebral and peripheral vascular disease. We are using these MRI techniques in prospective clinical studies to examine mechanisms of atherosclerosis progression, plaque features that are associated with an increased risk for stroke, and response to novel endovascular therapy aimed at reducing rates of arterial re-occlusion. We look forward to opportunities to collaborate with investigators at SLU to examine mechanisms of accelerated atherosclerosis progression and development of high-risk plaque amongst individuals with diabetes.

I lead a multidisciplinary team assessing the burden and impact of urological disorders associated with Type 1 diabetes, through an ancillary study of the Diabetes Control and Complications Trial/Epidemiology of Diabetes Intervention and Complication. My goal has been to understand the interaction of the genomic, metabolic, hormonal and epigenetic milieus of patients with diabetic complications. My current interest is in designing studies to identify high risk individuals and intervene with evidence based measures to reduce the risk of onset or worsening of symptoms.

Dr. Yuan's research in vessel wall and atherosclerosis imaging has direct applications related to diabetes. Diabetics have a much higher rate disease. Heart and blood vessel disease, cholesterol, and blood pressure are common risk factors associated with diabetes. Dr. Yuan's research into these factors benefits our understanding of the development and etiology of atherosclerosis in diabetics as well as the general population.

My research employs morphologic studies that utilize human renal biopsies to validate in human diseases the insights gained from studies of animal models. Examples of this include studies on platelet-derived growth factor (PDGF) and their receptors, vascular endothelial growth factor (VEGF), osteopontin, cell cycle regulatory proteins, and matrix proteins in diabetic nephropathy. We continue to characterize the BTBR ob/ob mouse model of diabetic nephropathy and other diabetic complications, including elucidating mechanisms underlying the role of podocyte regeneration in the regression of diabetic nephropathy that can be induced in this model. My lab is then translating these findings into comparable studies in humans using renal biopsies accessioned at the University of Washington.

We study how diabetes injures the kidney glomerulus, with a focus on cell death and fibrosis. We also study the role of resident stem cells to replace cells called Podocytes that are lost in diabetes, as these cannot self-renew. Their replacement is critical to limit proteinuria and glomerular scarring.

I am a clinician scientist specializing in the medical management of retinal and inflammatory diseases of the eye. Diabetes is a leading cause of retinal vascular disease, and inflammation contributes to disease severity. My laboratory studies the role of neutrophil extracellular traps (NETs) in ocular inflammation and how combined systemic and intraocular infection leads to chronic T cell mediated autoimmune uveitis. My clinical studies focus on developing non-invasive imaging techniques for use in the diagnosis and management of patients with vascular and inflammatory diseases of the retina and choroid.
