Brief description Diabetes, obesity, heart disease and physical inactivity are major and escalating health problems within western societies. These problems are all linked to, or aggravate, the condition known as insulin resistance. Insulin resistance occurs when normal levels of insulin are insufficient to remove glucose from the blood. In the normal situation, insulin regulates glucose uptake into muscle and fat cells by stimulating the movement of a glucose transport protein from inside the cell to the cell surface. The trafficking of this protein is somehow disrupted in insulin resistance. The purpose of this research is to follow up our exciting preliminary results on this system to shed light on the molecular processes that regulate the trafficking of the glucose transporter. Information resulting from our studies will lead to a better understanding of insulin-stimulated glucose transport and may also unravel the details of a related cellular secretion system that regulates neurotransmission. Our hope is that by understanding at the molecular level how cells regulate secretion, we can in the future develop therapeutics to counteract many of today s major health problems.
