The rapid interactions of circulating human blood platelets is critical to prevent bleeding, but can cause thrombotic diseases (heart attack, stroke). These highly regulated interactions involve specific adhesive proteins. Our studies will define factors regulating platelet interactions. Imaging the thrombotic process will quantify platelet function at an unprecedented resolution and we have a panel of new candidate reagents that will be assessed for antithrombotic potential.
Unraveling the variability in the protein expression in tissues or cell populations is critical to understand how cells respond to their environment. For example, this can provide details about the cellular response to an infection or to a chemoterapic. As of today, single cell protein analyses has become at reach, but its application is still cumbersome and its throughput is low. This proposal aims to develop and deploy a simple and robust method to analyse the protein content in single cells.

Summary
Bone marrow stem cells modified to express self antigen is proposed as a treatment for experimental autoimmune uveitis. A major goal of this research is to investigate the impact and possible mechanism of gene therapy on the development and progression of autoimmune disease in the eye to prevent or reduce the severity of disease.
The Essential Nuclear Transporter Importin 13; Key Role In Brain And Testis

Summary
Transport into and out of the nucleus, the control centre of cells, is critical for cell function in complex organisms such as mammals. The present proposal seeks to further understanding of a novel molecule mediating nuclear transport that has a novel inhibitory form in the testis, and important roles in the lung and nervous system. The results should help basic understanding of this molecule, and relate to disease conditions such as X-linked mental retardation and childhood asthma.

Summary
Artemisinin-based antimalarials (ARTs) save hundreds of thousands of lives every year. Unfortunately resistance of P. falciparum to ART is now emerging in South East Asia and it is critical to know how and why. We will determine what is different about resistant parasites and will develop assays to monitor drug resistance in the field. We have found that the immature form of the malaria parasite is more resistant to ARTs, which helps explain resistance. We will build on this to develop new targe ....Artemisinin-based antimalarials (ARTs) save hundreds of thousands of lives every year.

Characterising The Beta-catenin Nuclear Targeting Pathway In Cancer

Funding Amount
$485,081.00
Summary
Bowel cancer is caused by inherited gene mutations that cause build-up of beta-catenin protein in the cell nucleus. Bowel cancer is the second largest cause of cancer deaths in Australia. We aim to study the mechanisms controlling beta-catenin accumulation in the nucleus. We will characterise new signalling pathways that control movement and activity of beta-catenin in the nucleus. This will yield insights into the role of beta-catenin in cancer and possible targets for therapy.
Trafficking Of The Major Virulence Protein To The Host Cell Surface In Malaria Parasite-infected Erythrocytes

Funding Amount
$658,164.00
Summary
The malaria parasite infects human red blood cells and causes them to stick to blood vessels in the brain, inducing coma. This causes the deaths of ~2 million children each year. We will use cell biology techniques to manipulate malaria parasites to unravel the details of the molecular ticketing system that the parasite uses to get its adhesive proteins onto the red blood cell surface. The ability to interfere with this process would greatly decrease the impact of this major human pathogen.

Summary
Malaria kills between 1 and 3 million children each year. In addition, the disease debilitates the adult population in malaria-endemic areas, thereby contributing to the cycle of poverty in many third world countries. As resistance to existing antimalarial drugs increases, there is an urgent need to understand the workings of the parasite at a molecular level to enable the development of alternative antimalarial strategies.

In addition, the disease debilitates the adult population in malaria-endemic areas, thereby contributing to the cycle of poverty in many third world countries. As resistance to existing antimalarial drugs increases, there is an urgent need to understand the workings of the parasite at a molecular level to enable the development of alternative antimalarial strategies. During part of its life cycle, the malaria parasite infects the red blood cells of its human host. The parasite transports proteins to the red blood cell membrane so as to modify the properties of its adopted cellular residence. The parasite proteins that are deposited at or in the red blood cell membrane increase the leakiness and the stickiness of the parasitised red blood cells. This allows more efficient uptake of nutrients and allows the parasitised red blood cells to adhere to blood vessel walls, thereby avoiding passage through the spleen. Adherence of parasitised red blood cells to capillaries in the brain and the placenta is thought to lead to the development of the complications known as 'cerebral' and 'placental' malaria. These complications are responsible for the deaths of many children and pregnant women. We propose to use cell biology techniques to introduce foreign genes into malaria parasite-infected red blood cells to unravel the details of the molecular machinery and the ticketing system that the parasite uses to traffic its virulence proteins to their correct destinations. These studies could potentially lead to the development of novel intervention strategies. For example, if it were possible to decrease the levels of surface expression of a protein known as PfEMP1, adhesion of infected red blood cells would be inhibited. This would greatly decrease the impact of this important human pathogen.Read moreRead less
