Summary
Many very commonly used medications cause an allergic reaction in a small number of patients that receive them. The allergic reaction results in platelets being destroyed and puts the patients at risk of bleeding. The patient recovers slowly if the drug is stopped but there is no other treatment and no way to reverse the effect quickly if the patient starts to bleed. This project will try to understand the mechanism of the condition and test a potential treatment.

Summary
Improvements in treatment have seen some types of leukaemia (a cancer of white blood cells) being curable in up to 90% of patients with the disease; however, other types of leukaemia do not respond to these drugs and new approaches are needed. We have discovered that some leukaemia cells express a unique protein not made by any other cell type. This project will analyse how this aberrant protein is made and how this process contributes to the development of leukaemia. Also, since this protein is ....Improvements in treatment have seen some types of leukaemia (a cancer of white blood cells) being curable in up to 90% of patients with the disease; however, other types of leukaemia do not respond to these drugs and new approaches are needed. We have discovered that some leukaemia cells express a unique protein not made by any other cell type. This project will analyse how this aberrant protein is made and how this process contributes to the development of leukaemia. Also, since this protein is unique to the leukaemia cells, it offers the opportunity to develop magic bullets able to target specifically to the leukaemia cells and to kill them. This project aims to make one such drug and to conduct preliminary testing.Read moreRead less

Summary
Blood clots cause most heart attacks and strokes, and platelets are the blood cells that form these clots. Drugs that block platelet function, such as aspirin, are used to prevent heart attack and stroke but are frequently ineffective. Here, we will develop a new drug that prevents platelet incorporation into blood clots, that will be suitable for the prevention of heart attack and stroke in humans, and that may improve on existing therapies.
Autoimmune-based thrombocytopenia can be a life-threatening adverse event associated with viral load, surgery, drug therapies or the use of the anticoagulant, heparin. This grant will define mechanisms of anti-platelet antibody-dependent platelet activation and assess shedding of platelet-specific glycoprotein (GP)VI as an immediate consequence of this activation, provide a new strategy for evaluating risk of thrombosis in HIT.

Summary
My recent studies have demonstrated that a model of vitamin A deficiency results in impaired blood cell production and contributes to a blood cell disorder that can progress to leukaemia. There are also reduced numbers of blood stem cells (which give rise to all blood cells) and bone (which helps to regulate blood cell production) in this mouse model. In these studies I seek to understand more on how vitamin A deficiency causes these defects, which may lead to better treatment of such diseases.
