Summary
Platelets are small specialised blood cells that are essential for normal blood clotting and repair of damaged blood vessels following injury. We are studying the processes that enable platelets to stick to each other and to other cells to form a stable blood clot at the site of injury. The same processes, unchecked, are involved in the formation of harmful blood clots in the bloodstream that may block blood vessels in the heart or brain and result in a heart attack or stroke.

We are studying the processes that enable platelets to stick to each other and to other cells to form a stable blood clot at the site of injury. The same processes, unchecked, are involved in the formation of harmful blood clots in the bloodstream that may block blood vessels in the heart or brain and result in a heart attack or stroke. Platelets stick to the blood vessel wall through specialised adhesive proteins. These adhesion proteins are stored within the platelet and expressed on the cell surface when the platelets stick to the blood vessel wall. In conditions such as Gray Platelet Syndrome, the platelets are unable to store adhesion receptors, resulting in impaired blood clot formation. A clearer understanding of how platelets stick to the blood vessel wall will not only increase our knowledge of blood clot formation in health and disease, but also with the potential development of new therapies for the prevention of heart disease and stroke.Read moreRead less

Summary
Blood platelets play a key role in blood clot formation, prevention of bleeding and are the principal elements contributing to thrombosis leading to heart attack and stroke. Numerous studies have defined pathways promoting platelet activity, however less is known about their negative regulation. In this fellowship I will examine the role for proteins, Dok2 and Dok1, in the negative regulation of platelets, hoping this leads to development of novel therapeutics for prevention of cardiac disease.

Diabetes is a major and increasing cuase of death and disability in our society. This studies aims to understand the cellular and molecular mechaisms controlling insulin secretion from the pancreas, since defects in this secretion are involved in causing diabetes. The proposed studies are of relevance to both juvenile and adult-onset diabetes, and may lead to new treatment modalities, as well as potentially being relevant to the use of pencreatic islet cell transplantation in the treatment of di ....Diabetes is a major and increasing cuase of death and disability in our society.
