Summary
The cells of the blood play an important role in maintaining healthy blood vessels. We are interested in two types of blood cells, platelets and leukocytes, which together play a key role in vessel maintenance, by promoting blood clot formation and vessel wall repair following injury. However, while critical for normal blood vessel maintenance, these cells have also been demonstrated to contribute to disease states including atherosclerosis, thrombosis and inflammatory airway diseases.

We are interested in two types of blood cells, platelets and leukocytes, which together play a key role in vessel maintenance, by promoting blood clot formation and vessel wall repair following injury. However, while critical for normal blood vessel maintenance, these cells have also been demonstrated to contribute to disease states including atherosclerosis, thrombosis and inflammatory airway diseases. Underlying the function of both blood cell types is their ability to stick (or adhere) to each other. However the way in which they coordinate this adhesion is very complex. New information from our laboratory has demonstrated that the sticky behaviour of each cell type is spatially and temporally regulated, and may involve may factors both inside and outside of the cells themselves. Our studies aim to define the key components regulating the 'stickiness' of these blood cells, in order to undertand how they contribute to maintaining healthy vessel walls, but also how their stickiness may also contribute to the promotion of diseased vessels. This information will not only increase our knowledge of the factors that regulate blood clot formation, but may also assist in the development of new therapies to prevent and-or treat vessel disease.Read moreRead less
Investigating A Novel Role For The Haemopoietic Growth Factor Receptor, C-Mpl, In Regulating Shear-dependent Platelet Adhesive Function

Summary
Platelets play a critical role in blood clot formation, with low platelet numbers leading to bleeding while excessive clot formation can cause heart attack and stroke. Platelets must ‘stick’ to injured blood vessels under blood flow (shear). We have discovered that the growth factor, c-Mpl, can regulate shear-dependent platelet sticking by controlling receptor ‘shedding’ from the cell surface. We will investigate how c-Mpl performs this new role, and examine platelet function in patients with my ....Platelets play a critical role in blood clot formation, with low platelet numbers leading to bleeding while excessive clot formation can cause heart attack and stroke.

We have discovered that the growth factor, c-Mpl, can regulate shear-dependent platelet sticking by controlling receptor ‘shedding’ from the cell surface. We will investigate how c-Mpl performs this new role, and examine platelet function in patients with myeloproliferative disease who have reduced c-Mpl.Read moreRead less

Summary
Cardiovascular disease, including heart attack and stroke is the major cause of death globally, and is responsible for the death of 50,000 Australians each year. Platelet activation and blood coagulation play an important role in these diseases and we have discovered that a protein called 14-3-3 zeta is important in the processes that result in thrombosis. We are studying the mechanisms by which this protein contributes to life-threatening platelet activation with the aim of developing new and m ....Cardiovascular disease, including heart attack and stroke is the major cause of death globally, and is responsible for the death of 50,000 Australians each year. Platelet activation and blood coagulation play an important role in these diseases and we have discovered that a protein called 14-3-3 zeta is important in the processes that result in thrombosis. We are studying the mechanisms by which this protein contributes to life-threatening platelet activation with the aim of developing new and more effective anti-thrombotic drugs.Read moreRead less
