Transplantation of pancreatic islets is the only cure for type 1 diabetes (T1D). Unfortunately, many of the transplanted islet cells die quickly due to an inadequate supply of blood. Herein, we investigate a novel cell surface protein for its role in islet and blood vessel survival and function. Furthermore, we use nanotechnology to provide said protein to the islet cells during transplantation for increased survival and function. Ultimately, this work may cure more patients with diabetes.

Summary
All cells contain on their surface a class of molecules, cell adhesion molecules, that enable them to adhere to other cells in tissues. Cell adhesion molecules have long been known to be involved in the guidance of axons to their targets during development. However the molecular mechanisms by which these molecules act are largely unknown. We propose to use the powerful genetic tools available in the fruitfly to dissect the mechanisms by which two cell adhesion molecules promote axon growth.
The glomerulus is the filtering component of the kidney. In many diseases, it can be the target of an inappropriate inflammatory response. As part of this response, white blood cells accumulate in the glomerulus where they cause damage. The aim of the project is to determine how these white blood cells accumulate in the glomerulus, specifically asking the question, what molecules present on the white blood cells and the glomerular blood vessels are required for this accumulation?
Multifunctional biodegradable nanoparticles for enhanced DNA vaccine delivery. DNA vaccine, which shows better immunological and economic merits than conventional vaccines, suffers clinical failure due to the difficulty of delivering intact DNA molecules to relevant cells. This project seeks to develop smart polymer nanospheres to protect the DNA molecules from premature degradation in order to improve its efficacy.

Summary
Bioaffinity mass spectrometry infrastructure to identify small molecules binding to therapeutic targets. The development of anti-infective therapies is challenging because the underlying biology and biochemistry of pathogen virulence is not yet completely understood. This mass spectrometer facility will be used to identify small molecules suited for development into new therapies for malaria, tuberculosis and HIV.
Understanding allosteric modulation and functional selectivity at G Protein-Coupled Receptors (GPCRs). GPCRs are an important superfamily of proteins that are involved in a myriad of physiological processes and a wide range of serious illnesses. This project seeks to gain a more detailed understanding of new mechanisms of GPCR modulation and function that will be of direct relevance to drug discovery.
Subtype selectivity and functional bias of receptor positive allosteric modulators for understanding models of pulmonary disease. G-protein-coupled receptors (GPCRs) are an important superfamily of proteins that are involved in a myriad of physiological processes and a wide range of serious illnesses. This project seeks to gain a more detailed understanding of new mechanisms of GPCR modulation and function that will be of direct relevance to drug discovery.

Summary
Novel chemical tools to study cathepsin X activation. This project aims to develop new chemical tools that can measure the specific activation of cathepsin X in cells, tissues, and live animals, as well as specific inhibitors for cathepsin X. The cysteine protease cathepsin X mediates basic biological functions that are essential for life, including cell communication, phagocytosis, immune maturation and neuritogenesis. The outcomes should benefit the wider research community. They could have lo ....Novel chemical tools to study cathepsin X activation.

They could have long-term implications for health and disease, and deliver economic benefits through commercialisation of the novel tools.Read moreRead less
