Summary
Extracorporeal Membrane Oxygenation (ECMO) is advanced life support, which can save critically ill children. Significant bleeding occurs in 39%; clotting in 31% of children on ECMO; stroke in 12%. The biggest barrier to reducing these complications is the lack of understanding of how the bleeding/clotting system works in ECMO. This unique proposal uses the largest paediatric ECMO population in Australia and a multidisplinary expert team to develop a mechanistic understanding of these issues.
Investigating The Contribution Of Distinct Mitochondrial Cell Death Pathways To Platelet Survival And Function

Summary
Platelets are small blood cells that form clots to stop bleeding. We have found new and unexpected roles for 2 distinct pathways that regulate cell death in the process of blood clot formation. We will study the precise role of these pathways in blood clot formation, and determine whether they may also regulate the survival of platelets stored by the blood bank for transfusion. These studies will provide new insight into the role of cell death pathways in blood clot formation, and may help to im ....Platelets are small blood cells that form clots to stop bleeding.

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.
