Our research has identified unprecedented communications between the microbes that colonize our body’s surfaces and killer T cell immunity. Our findings indicate that microflora is key to a healthy balance between two immune mediator systems that have opposing effect on T cell immunity. The project will extend our understanding of how this regulated and seeks to harness these novel insights to explain the well known, but poorly understood role of microbes in autoimmune diseases.
Improving Patient Outcome Following Arthroscopic Autologous Chondrocyte Implantation

Summary
Autologous chondrocyte implantation (ACI) is the ‘gold standard’ for treating knee cartilage defects. Traditionally, ACI was performed through open surgery. However, ACI can now be performed through ‘keyhole’ surgery, decreasing the co-morbidity of open surgery. Furthermore, optimal patient outcome is limited by a lack of knowledge in effective post-operative rehabilitation. This project will evaluate outcomes following ACI performed through keyhole surgery, in conjunction with 'accelerated' reh ....Autologous chondrocyte implantation (ACI) is the ‘gold standard’ for treating knee cartilage defects.

Understanding The Cardio-protective Actions Of The AT2R In Females: Shifting Gears Between AT1 And AT2 Receptor Balance Of Function With Relaxin.

Summary
Women are protected from cardiovascular disease as compared to age-matched men, an effect lost with age. Understanding protective factors that act in females could be used to treat hypertension, heart failure and stroke in males at all ages, and maintain protection in elderly women. Our studies aim to determine if relaxin, an ovarian hormone, can promote cardiovascular health in women.
Extra Corporeal Membrane Oxygenation (ECMO) is a heart/lung machine that replaces blood CO2 with oxygen, giving organs a chance to rest after injury due to infection or trauma. It saved many lives in the swine flu outbreak. Blood moving across foreign surfaces causes inflammation, cell injury and a need for transfusions. This study aims to identify which part of the ECMO causes injury and how. This will to improve survival rates of the most severe forms of cardiac and respiratory disease.
Molecular Pathways That Control Differentiation And Function Of Tissue-resident Memory T Cells

Summary
T cells residing in organs such as gut, liver or skin guard against infection and are critical for preventing tumour development. We found that the combined activities of two factors, Blimp1 and Hobit, are critical for the development of these so-called tissue-resident T cells. Using a series of new tools, we will identify how the molecular network required for the development of tissue-resident T cell is established. This may allow us to harness their critical functions in therapy.
Deciphering The Metabolic And Endocrine Profile Of Healthy Adipocytes

Summary
Obesity is associated with the development of metabolic diseases, however, it is becoming clear that it is where the excess fat is stored that is more important when predicting the health risks associated with obesity. This project aims to identify whether adipocyte progenitor cells, which eventually become fat cells, are ‘preprogrammed’ and whether differences in these cells explain the generation of either healthy or unhealthy fat in different locations of the body.
Comparison Of Periodontal Ligament Stem Cells And Induced Pluripotent Periodontal Ligament Stem Cells For Periodontal Regeneration

Funding Amount
$831,955.00
Summary
In the first part of this study we will determine whether induced pluripotent stem cells or adult stem cells from the periodontal ligament are better candidates for periodontal regeneration. Secondly, using CAD/CAM technology we will make tissue engineering scaffolds tailored to fit periodontal defects and seeded with stem cells to improve on current techniques used to regenerate damaged tissues around teeth affected by periodontal disease.
Investigating Human Keratinocyte Stem Cells And Their Microenvironmental Niche

Summary
The stem cells in the outer protective layers of the epithelium of the skin (keratinocyte stem cells), possess an intrinsically high capability to regenerate tissue. However, this tissue regenerative ability can be enhanced by interactions with microenvironmental elements i.e. connective tissue cells and proteins. This study seeks to investigate specific keratinocyte-microenvironment interactions which will ultimately be used to improve current methods for generating skin tissue for burns patien ....The stem cells in the outer protective layers of the epithelium of the skin (keratinocyte stem cells), possess an intrinsically high capability to regenerate tissue.

Osteochondroreticular Stem Cell Therapy For Osteoarthritis: The Right Cells For The Job.

Funding Amount
$561,956.00
Summary
"Wear and tear" arthritis of the knee, hip and back joints is known as osteoarthritis. This causes significant health burden and costs in our community, particularly in older Australians. Osteoarthritis begins with the loss of joint cartilage. We believe that a new type of stem cells (OCR stem cells) offer the greatest promise to generate and thus therapeutically replace joint cartilage. Our studies test this hypothesis and develop preclinical translation of our discoveries in mice into humans.
The Role Of Endogenous Glucocorticoids In The Pathogenesis Of Osteoarthritis
Funder

Funding Amount
$587,697.00
Summary
Osteoarthritis (OA) is a degenerative joint disease and a leading cause of disability. Recently, we found that the development of experimental OA in mice can be slowed if the effects of the body’s own (=endogenous) glucocorticoids were blocked locally. This project will determine how endogenous glucocorticoids accelerate the development of OA. We will further test whether treatment with drugs that block the actions of endogenous glucocorticoids can slow or prevent the development of OA.
