Type 1 Diabetes

Georgia Laboratory

While insulin injections and other pharmaceuticals help patients manage their diabetes, there is no definitive cure. Replacement of lost insulin-secreting cells may be the key to a cure. The lab of Senta Georgia, PhD, uses a three-pronged approach to design novel strategies for making new insulin-secreting cells, studying the basic biology of insulin-secreting cells and translating that knowledge into potential cell replacement strategies for type 1 diabetes patients.

De Filippo Laboratory

The lab of Roger De Filippo, MD , focuses on new uses of stem cells and other techniques for organ regeneration and cell therapeutics. Current research includes new stem cell studies for heart disease and diabetes. The goal is to search for potential applications that can be used to prevent these diseases and/or significantly delay the damage they cause.

Obesity

Early Life Determinants of Obesity and Diabetes

There is growing appreciation that developmental programming of neuroendocrine systems by the perinatal environment may cause obesity and diabetes. The Sebastien G. Bouret, PhD Lab is exploring the role of perinatal hormones in influencing the development of hypothalamic pathways involved in appetite regulation.
