Examining novel cell signalling in the regulation of platelet structure and function. Pharmaceutical inhibition of platelet function is the primary therapy for prevention of arterial thrombosis – the most common cause of death and disability in Australia. However, current therapies have limited efficacy. Defining platelet activation mechanisms in order to rationalise more effective antithrombotic approaches is the major focus of this research. This project describes the first studies to examine ....Examining novel cell signalling in the regulation of platelet structure and function. Pharmaceutical inhibition of platelet function is the primary therapy for prevention of arterial thrombosis – the most common cause of death and disability in Australia. However, current therapies have limited efficacy. Defining platelet activation mechanisms in order to rationalise more effective antithrombotic approaches is the major focus of this research. This project describes the first studies to examine the importance of a family of intracellular signalling enzymes, the Class II phosphoinositide 3-kinases, in platelet function. These studies will define the contribution of these enzymes to platelet production and function and will establish whether their inhibition is an attractive strategy for the prevention of arterial thrombosis.Read moreRead less

Summary
Export of effector proteins by P. falciparum to the infected red blood cell. Infection by the malaria parasite has lethal consequences for humans. The parasite exports hundreds of proteins via a translocon to commandeer the red blood cell. This project aims to determine the function of one of the major translocon components and determine if it is a viable target for anti-malarial drug development.
Studying precancerous stem cells that cause T cell leukaemia. Recent research has identified abnormal stem cells that are the cause of T cell leukaemia. They are also resistant to therapeutics suggesting that they could be a cause of relapse. The aim of this project is to determine the abnormal pathways that cause these cells to become immortal and to determine new therapeutic strategies to eliminate them.
Analysing the protective role of platelets during malaria infection. Platelets protect the host during malarial infection. This project aims to study how platelets kill the malaria parasite by investigating the role of host molecules and their potential as novel antimalarial agents. The role of platelets in the pathogenesis of cerebral malaria syndrome will also be investigated.
Defining how molecular switches program cell identity during development. Aims: This project aims to investigate how molecular switches known as transcription factors, work together to turn genes on or off to program cell identity during development.
Significance: This project expects to generate new knowledge in the area of genetics and developmental biology using collaborative, cutting edge technologies.
Outcomes: Expected outcomes of this project include the identification of new genes impor ....Defining how molecular switches program cell identity during development. Aims: This project aims to investigate how molecular switches known as transcription factors, work together to turn genes on or off to program cell identity during development.
Significance: This project expects to generate new knowledge in the area of genetics and developmental biology using collaborative, cutting edge technologies.
Outcomes: Expected outcomes of this project include the identification of new genes important for programming the identity of cells that comprise our blood vessels, lymphatic vessels and circulating blood cells.
Benefits: Data generated will underpin the development of approaches to program/reprogram stem cells to produce mature cells for transplantation or tissue engineering purposes ex vivo.Read moreRead less
Short silk nanofibre based 3D scaffolds with enhanced biomimicry. This project aims to understand the behaviour of haematopoietic stem cells (HSC) in novel 3D scaffolds based on short silk nanofibres. This will lead to highly functional 3D scaffolding materials that support efficient HSC renewal in vitro. This project aims to overcome the key problem with existing in vitro systems, which lack the morphological and biochemical complexities of native HSC-niche. Since haematopoietic stem cells are ....Short silk nanofibre based 3D scaffolds with enhanced biomimicry.

This will lead to highly functional 3D scaffolding materials that support efficient HSC renewal in vitro. This project aims to overcome the key problem with existing in vitro systems, which lack the morphological and biochemical complexities of native HSC-niche. Since haematopoietic stem cells are the precursors to all blood cells, this project has the potential of engineering a high yield artificial ‘blood factory’, which will help save the lives of many thousands of people who rely on bone marrow transplants to treat life-threatening illness such as leukaemia.Read moreRead less

Summary
An advanced flow cytometry facility for the Peter Doherty Institute. The establishment of a flow cytometry facility in the new Peter Doherty Institute for Infection and Immunity will enhance capacity to investigate immunity to a broad range of very serious diseases. This project will support researchers studying viral and bacterial infection as well as cancer and autoimmunity.
Inhibiting pathological signalling in haematopoietic disease. Certain leukaemias and other blood diseases are caused by the mutation of one particular molecule, called Janus Kinase (JAK), inside our bodies. This project aims to understand the biochemical details of these diseases by studying this mutated molecule in detail. The project will aim to provide the information for developing effective therapeutics against these diseases.
Improved cryopreservation protocols for long term storage of platelets. The aim of this project is to characterise human blood platelet deterioration during cold storage and cryopreservation, and accelerate the development of improved long-term storage options. The project expects to generate important new knowledge about how platelets deteriorate during storage, and how such deterioration can be minimized. The expected outcomes are improved methods for long term platelet storage. This should be ....Improved cryopreservation protocols for long term storage of platelets. The aim of this project is to characterise human blood platelet deterioration during cold storage and cryopreservation, and accelerate the development of improved long-term storage options. The project expects to generate important new knowledge about how platelets deteriorate during storage, and how such deterioration can be minimized. The expected outcomes are improved methods for long term platelet storage. This should benefit blood donation services and hospitals by improving platelet delivery to remote locations, reducing wasted blood and the number of donations required, leading to significant financial savings.Read moreRead less
Biomimetic blood bag materials for prolonged platelet storage. Platelet storage is limited to five to seven days before there is a reduction in viable platelets. This results in a continual mismatch between supply and demand resulting in patients in remotes areas or those that have rare phenotypes missing out on platelets. It also results in the wastage of platelets because they expire before they can be used clinically. This project aims to extend the platelet shelf life beyond seven days by de ....Biomimetic blood bag materials for prolonged platelet storage.

This results in a continual mismatch between supply and demand resulting in patients in remotes areas or those that have rare phenotypes missing out on platelets. It also results in the wastage of platelets because they expire before they can be used clinically. This project aims to extend the platelet shelf life beyond seven days by developing biomimetic blood bag materials that reflect the natural molecular structures of blood vessels through the use of novel synthetic and biological materials. With the realisation of longer platelet storage times, this project aims to have significant impacts on the health and economic benefits of Australians.Read moreRead less
