Understanding the molecular basis for the development of type-2 diabetes
Type-2 diabetes (T2D) is a highly prevalent disease whose incidence is increasing at an alarming rate due to the obesity epidemic. This is because obesity results in the development of insulin resistance. Although the majority of obese people develop insulin resistance, they do not develop diabetes due to a compensatory increase in insulin secretion from the pancreatic beta-cells. This is enabled by an increase in both pancreatic beta-cell function and mass. Critically, it is the failure of the beta-cells to compensate and/or maintain a compensatory phenotype that ultimately leads to the development of T2DM. This is characterised by the development of beta-cell dysfunction and ultimately beta-cell death. My laboratory is focused on understanding the molecular basis for beta-cell compensation and the development of beta-cell dysfunction. This work is important not only in the development of a fundamental understanding of beta-cell physiology but also in understanding the pathophysiology of type-2 diabetes, which in turn may lead to the identification of new rational strategies for the treatment and possible prevention of this disease.
Current areas of active research
- The role of mTOR in beta-cell compensation and dysfunction.
- ER stress and the unfolded protein response (UPR) in health and disease (principally in relation to type-2 diabetes).
- The role of amino acid transporters in beta-cell function and type-2 diabetes.
