Summary
Type 2 diabetes (T2D) affects 7% of Australians and is a major cause of morbidity and mortality. A failure of insulin secretion contributes to T2D, and this is linked to the inability of insulin producing ?-cells to use lipids appropriately (lipotoxicity). Here we will study the role of the immune system and how this inhibits insulin secretion in T2D
Mechanisms Of PKCepsilon-dependent Regulation Of Beta-cell Lipid Metabolism And Insulin Secretion

Summary
Lipid loading of the insulin-producing beta cells of the pancreas contributes to the onset of Type 2 diabetes, but the mechanisms are poorly understood. We have recently established that inhibiting the enzyme PKCe helps restore insulin secretion. By better defining the cellular role of PKCe we will clarify how insulin secretion is disrupted by fatty acids and cholesterol.
