overview

Dr. Sarah Tersey is an islet biologist whose research focuses on the role of the ß-cell in the development of type 1 and type 2 diabetes. The primary goal of her research focuses on understanding the molecular pathways that play a role in the development of diabetes. Specifically, pathways that include the enzymes 12-lipoxygnease and deoxyhypusine synthase. By using inhibitors against these pathways or creating genetic deletions of either of these genes, Dr. Tersey has shown that diabetes can be prevented. A second major focus of her research is the development of biomarkers that will best predict the likelihood of any one individual’s risk to develop type 1 diabetes. Within this concept, she demonstrated that the dysfunction of the pancreatic islet precedes the onset of type 1 diabetes. This research has changed the standard dogma of the islet as a silent bystander to the immune system, to the new way of thinking – that the pancreatic islet is a major player in its own demise during the pre-course of type 1 diabetes.
