Diabetes is the largest cause of kidney disease in the world. In fact, approximately 10% to 20% of mortality in diabetic patients is resulted from the kidney (renal) failure. PriMed Shines provides a large collection of well-characterized naturally diabetic non-human primate (NHP) models. Our diabetic NHP models develop diabetic kidney disease with similar phenotypes as human patients, including hyperglycemia, glycosuria, albuminuria, and low GFR, providing the ideal animal model for investigating the mechanisms underlying human DKD, as well as for pharmaceutical discovery, development, and evaluation of novel therapeutic agents.
