Summary
Skeletal joint injuries often heal poorly with current treatment approaches and lead to the onset of osteoarthritis. This project will produce a synthetic graft with unique properties to mimic the complex structure of joint tissues, and high bioactivity to induce optimal healing of the joint. This graft will constitute a viable alternative for the treatment of skeletal joint defects, resulting in significant healthcare benefits and improved long-term outcomes.
To Repair An Osteo-chondral Defect In An Experimental Rabbit Model Using A Structured 3D Nano-composite Scaffold Loaded With Mesenchymal Stem Cells (MSC)

Summary
The treatment of cartilage damage is a major problem in orthopaedic practice. The use of a 3D scaffold may overcome many challenges associated with cartilage and bone repair and regeneration. The aim of this research is to culture bone and cartilage cells into a prefabricated scaffold which may then be tested in an animal model. The results of this research may offer a new method of treating post-traumatic and osteoarthritic defects.
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.

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.

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.
Effects Of Ischemia/ Reperfusion Injury On Enteric Neurons And Neuroprotective Strategies

Summary
The intestine can suffer restricted blood flow, creating a region of damaged or dead bowel. This leads to severe medical emergencies, complications and even death. Loss of blood flow and damage can be a serious complication for intestinal transplant surgery, which compromises patient survival and recovery. The project brings together transplant surgeons and basic scientists to solve problems caused by intestinal ischemia. A major result will be to improve outcomes for Australian patients
