Solid-phase synthesis of sulfopeptides for evaluation of chemokine-receptor recognition. This research program will develop new chemical methods for preparing biologically active molecules that contain sulphate. These molecules have important functions in controlling blood clotting, hormone activity, immune responses, and AIDS or malarial infection. The new chemical methods will be used to study the interactions of two groups of proteins that control the movement of white blood cells in inflamma ....Solid-phase synthesis of sulfopeptides for evaluation of chemokine-receptor recognition. This research program will develop new chemical methods for preparing biologically active molecules that contain sulphate. These molecules have important functions in controlling blood clotting, hormone activity, immune responses, and AIDS or malarial infection. The new chemical methods will be used to study the interactions of two groups of proteins that control the movement of white blood cells in inflammatory responses. The research will provide insights into the biochemistry of inflammation and will contribute to the development of new therapies for diseases affecting young Australians (allergy, asthma, and viral infections) as well as the elderly (atherosclerosis and arthritis).Read moreRead less
Airway Smooth Muscle Contribution To Remodelling In Asthma.

Summary
Asthma is an airway disease that affects more than 10% of adults and 25% of children in Australia and in 1998 caused 675 deaths. The cost to the community is in excess of $720 million a year. The abnormality in asthma is not fully understood, however inflammation, changes to the structure of the airways and excessive airway narrowing are key factors. Inflammation and the allergic reactions which accompany asthma cause fluid to leak from tiny blood vessels in the lung.

The cost to the community is in excess of $720 million a year. The abnormality in asthma is not fully understood, however inflammation, changes to the structure of the airways and excessive airway narrowing are key factors. Inflammation and the allergic reactions which accompany asthma cause fluid to leak from tiny blood vessels in the lung. This fluid and the inflammation are linked to changes in the airway which include structural protein deposition - breakdown and an overgrowth of the smooth muscle that lines the walls of the airway. Our work is focussed on understanding the relationship between the structural protein deposition - breakdown and excess muscle growth. We also hope to gain a better understanding of the way asthma treatments combat these changes in the asthmatic airways.Read moreRead less
Defining the biosynthesis and immunological properties of complex bacterial glycolipids. We will study how sugar-lipids are made by industrially, agriculturally and medically important bacteria, and how they interact with the immune system. This will provide new insights into cell wall biosynthesis of importance to the biotechnology industry and identify new reagents for manipulating the immune system.
NOVEL TRI-BLOCK CO-POLYMERS FOR CONTROLED RELEASE OF PROTEINS FOR OSTEOGENESIS. This research is being driven by the need for a scaffold for orthopaedic reconstruction that provides controlled release of growth factors to enable rapid healing. None of the current systems possess the required combination of properties to enable new tissue to regenerate rapidly. The aim of this project is to design a system for sustained drug release using block copolymer micelles to encapsulate growth factors and ....NOVEL TRI-BLOCK CO-POLYMERS FOR CONTROLED RELEASE OF PROTEINS FOR OSTEOGENESIS. This research is being driven by the need for a scaffold for orthopaedic reconstruction that provides controlled release of growth factors to enable rapid healing. None of the current systems possess the required combination of properties to enable new tissue to regenerate rapidly. The aim of this project is to design a system for sustained drug release using block copolymer micelles to encapsulate growth factors and then polymerising the micelles in a biodegradable polymer scaffold. This would enable local delivery of osteogenic growth factors to a bone defect.Read moreRead less
Detecting Bioactivity In A Naturally-occurring Aggrecan Fragment

Funding Amount

Summary
The dynamic balance of anabolic and catabolic processes in healthy cartilage is disturbed in arthritis, with increased catabolism leading to irreparable cartilage damage. We will study the ability of a naturally-occuring aggrecan fragment to modulate cartilage catabolism. Our in vitro and in vivo experiments suggest that the aggrecan fragment limits cartilage destruction. This study tests our hypothesis that the aggrecan fragment antagonises cartilage damage and promote cartilage repair.
Synthetic extracellular matrices for control of cellular reprogramming. This project aims to design materials that control the cellular environment for the fast, efficient, and reproducible production of reprogrammed cells in embryo-like architectures. Regenerative medicine has entered a new era, where reprogramming a patient’s cells is now possible for studying and treating disease. The expected outcomes of this project include mechanistic details of cell reprogramming, design rules for 3D prin ....Synthetic extracellular matrices for control of cellular reprogramming.

Regenerative medicine has entered a new era, where reprogramming a patient’s cells is now possible for studying and treating disease. The expected outcomes of this project include mechanistic details of cell reprogramming, design rules for 3D printing of living cells and commercially viable reprogramming materials. The project expects to contribute fundamental knowledge in materials and biomedical sciences, while providing tools that will benefit commercial ventures in cell and tissue manufacturing.Read moreRead less
The Role Of The Human RECK Protein In Modifying Human Sarcoma Progression Within In Vitro And In Vivo Models
Funder
National Health and Medical Research Council
Funding Amount
$34,878.00
Summary
The protein “RECK” is known to have a controlling effect on cancers by reducing growth, invasion, and blood supply. RECK is present in normal tissues but in bone and soft-tissue tumours (sarcomas), the protein is reduced. This study aims to; correlate RECK levels in sarcoma with patient survival, use gene technology to increase RECK levels in sarcoma cells, and observe the effects on sarcoma invasion and metastasis.
