Dramatic improvements in microscope hardware and software and in the range of fluorescent markers used to tag selected cellular components now provide new and exciting opportunities to localise and determine the function of ions and molecules not only in preserved samples but also, most excitingly, in living cells. The proposed multiphoton confocal microscope will allow researchers in Canberra to obtain high quality images of static and moving components in living cells and tissues and will facilitate the discovery of new knowledge that contributes to our understanding and control of development and disease in both plants and animals.Read moreRead less
Spatial And Temporal Dimensions Of Mu-opioid Receptor Signalling: Implications For The Development Of Tolerance
Funder

Funding Amount
$799,316.00
Summary
The use of morphine as an analgesic is still limited by undesirable side effects such as tolerance. Despite decades of research, the mechanisms behind the development of tolerance are poorly understood. The ? opioid receptor is a protein expressed at the surface of the cells that is the target of morphine. This project will investigate the signalling events triggered by opioids with unprecedented resolution and will aim to elucidate why morphine elicits more tolerance than other opioid drugs.
Activation of invasion in Toxoplasma. Host cell invasion is critical for the establishment and maintenance of infection by the single-celled parasite Toxoplasma gondii, the causative agent of Toxoplasmosis. This project will use the latest molecular techniques to understand how invasion is activated and will define a new set of drug targets to treat Toxoplasmosis and related diseases.
Regulation Of Ca2+/calmodulin Dependent Protein Kinase Kinase-2 By Phosphorylation

Funding Amount
$570,334.00
Summary
This project will study the regulation of an enzyme called CaMKK2, which plays a pivotal role in controlling a number of important biological functions including brain development, regulation of appetite, energy metabolism and blood pressure. Understanding how this enzyme is regulated may open new avenues for treating Type 2 diabetes, obesity, and cardiovascular disease.
The dramatic increase in obesity and age-related metabolic disorders demonstrates the importance of gaining a better understanding of how cells and organisms regulate their energy stores. This project will identify novel molecular mechanisms that control the enzyme CaMKK2, which is a key regulator of whole-body energy metabolism. This will provide new opportunities to inform more effective strategies to tackle metabolic diseases, and improve health in an increasingly ageing population.
Dynamic regulation of cell signalling scaffolds. This project aims to determine how cells utilise scaffold-type signalling proteins to orchestrate, over time, diverse cellular responses critical for normal development and physiology. The project expects to generate fundamental new knowledge in cell and synthetic biology with broad relevance that will foster establishment of new international linkages and networks. This research should benefit the biotechnology sector by identifying strategies fo ....Dynamic regulation of cell signalling scaffolds.

Mechanisms of memory function involving site-specific tau phosphorylation. This project aims to understand the molecular principles that facilitate encoding, maintenance and retrieval of memories in the brain. To store memories in brain circuits, electrical and chemical signals are crucial. Brain cells can integrate signals into biochemical modifications of intracellular proteins. The nature of the protein modifications that represent memory within brain cells is unknown. This project uses innov ....Mechanisms of memory function involving site-specific tau phosphorylation. This project aims to understand the molecular principles that facilitate encoding, maintenance and retrieval of memories in the brain. To store memories in brain circuits, electrical and chemical signals are crucial. Brain cells can integrate signals into biochemical modifications of intracellular proteins. The nature of the protein modifications that represent memory within brain cells is unknown. This project uses innovative genome editing, mathematical modelling and proteomic approaches, to study how biochemical modifications of a key protein called tau help encode and retrieve memories. These molecular insights will make a significant advance in the current understanding of a brain function that is essential to all human activities.Read moreRead less

Blood flow haemodynamics affect cardiovascular health and morphogenesis. This project will highlight the role of TRPV4 channels in the short- and long-term adaptive responses to shear stress and will also have significant potential for application in future drug discovery.Read moreRead less
Nano-scale organisation of cellular adhesions. Cell migration is a key aspect of many normal processes but also of diseases such as cancers. This project will use a novel fluorescence microscope that can see single proteins to identify how cell adhesions are formed, remodelled and disassembled. This knowledge will help to design better drugs against cancers and novel implantable materials.
