Summary
Dendritic cells (DCs) are a blood cell type with a crucial role in our immune system. They are made in the bone marrow from stem and progenitor cells. How each of these cells individually makes DCs is complex and dynamic. We seek to understand this using cutting edge technologies to track each cell’s step-by-step role in this important process. This knowledge may help the use of DCs in the treatment of several diseases including autoimmunity and cancer.

Summary
Multiple Sclerosis is the most common neurodegenerative disease affecting young adults. It is a disease that kills myelin cells, which are necessary support cells for neurons and are critical for their function. This research investigates the role that the signal transduction of bone morphogenic protein plays in myelin cell production and myelin repair. Our aim is to identify regenerative therapeutics for Multiple Sclerosis.

Summary
Deloitte Access Economics data proposes the total economic burden of liver disease in Australia in 2012 was >$50 billion. This study will identify how the liver heals itself by inducing liver cell populations which interact to regenerate damaged liver tissue in chronic liver disease. This knowledge may lead to the development of novel therapeutic interventions for the treatment of liver scarring and liver cancer, and to assist in normal liver regeneration following chronic liver disease.

Summary
Many important bodily functions including growth, metabolism, onset of puberty, fertility, lactation and the ability to cope with stress are controlled by hormones secreted by the pituitary gland. Consequently, insufficient hormone production by the pituitary gland (hypopituitarism) results in life-threatening conditions which are a significant clinical problem. Growth Hormone (GH) deficiency is the most common form of pituitary hormone deficiency, affecting 1:3,500 individuals.

Consequently, insufficient hormone production by the pituitary gland (hypopituitarism) results in life-threatening conditions which are a significant clinical problem. Growth Hormone (GH) deficiency is the most common form of pituitary hormone deficiency, affecting 1:3,500 individuals. Currently, GH deficiency is treated by daily injections of growth hormone at a cost of $30,000 to $50,000 per patient per annum. However, even with daily injections and despite the cost, it is difficult to mimic the naturally fluctuating hormone levels in the body, resulting in incomplete growth rescue. Long term injections also have severe side effects that can lead to cardiovascular problems, abnormal bone density, diabetes and cancers of various types. To overcome the disadvantages of hormone therapy we are investigating a new cell replacement therapy to treat GH deficiency. This approach requires knowledge about the mechanism by which GH-secreting cells are generated and maintained in the adult pituitary. For the first time, we have isolated a type of progenitor (unspecialised) cell from adult mouse pituitary that is capable of dividing and generating GH-secreting cells. Our current research aims to further purify these cells and to show that they are capable of secreting GH in response to biologically relevant signals. In addition, we will test whether these cells can grow and develop into functional cells when introduced into mice. In particular, we will test whether the progenitor cells can rescue dwarfism using a mouse model of GH deficiency. This pioneering study will provide the first insight into the possibility of cell therapy for the pituitary, and may ultimately lead to the development of better therapies for patients with GH deficiency.Read moreRead less

Summary
Multiple sclerosis (MS) is the most common neurodegenerative disease affecting young adults. It is a disease that kills myelin cells, which are important support cells for neurons and critical for neuronal function. This research investigates the role of a specific signaling pathway with respect to myelin cell production and repair with the ultimate aim of identifying regenerative therapeutics for MS.

Summary
Collectively, diseases of the blood vascular system contribute immensely to the burden of health care in Australia. Notably, abnormal blood vessel formation is a major cause or contributor to many diseases, such as cancer, cardiovascular disease, rheumatoid arthritis, ischemia injury and diabetes. This project aims to understand the underlying mechanisms associated with aberrant angiogenesis such that it may aid in the identification of novel targets for the development of therapeutics.
