Summary
The control of neuroplasticity in the brain. This project aims to determine how neuroplasticity – the brain’s ability to remodel and make new circuits – is controlled in both excitatory and inhibitory neurons. This capacity, vital for all cognitive functions, diminishes as people age. It is imperative to determine neuroplasticity’s mechanisms and how and why they change, but it is not known how both excitatory and inhibitory neurons contribute to neuroplasticity and how these dynamic alterations ....The control of neuroplasticity in the brain.

It is imperative to determine neuroplasticity’s mechanisms and how and why they change, but it is not known how both excitatory and inhibitory neurons contribute to neuroplasticity and how these dynamic alterations are controlled. Understanding neuroplasticity is vital for learning, memory and healthy ageing throughout life.Read moreRead less
Conductance states of a brain glutamine transporter. Brain transporters are the target for many neuroactive drugs that are used to treat anxiety, depression and other psychotic disorders. Transport processes are also targeted to deliver neurotransmitter precursors to the brain to treat disorders such as Parkinson's disease. In this project we will study a transport process crucial for the function of neurons that release glutamate and GABA (gamma-aminobutyric acid) as neurotransmitters.

Transport processes are also targeted to deliver neurotransmitter precursors to the brain to treat disorders such as Parkinson's disease. In this project we will study a transport process crucial for the function of neurons that release glutamate and GABA (gamma-aminobutyric acid) as neurotransmitters. The study of this transport process will be important for understanding disorders like epilepsy and other disorders affecting neuronal excitability.Read moreRead less
Targeting brain lipid homeostasis to treat Alzheimer's disease. Dementia affects approximately 250,000 people in Australia at an estimated cost (in 2002) of $6.6 billion per annum. The major cause of dementia (accounting for approximately 70% of all cases) is Alzheimer's disease (AD); a progressive neurodegenerative illness for which there is no curative or disease-stalling treatment. Due to increases in life expectancy, the incidence of AD is predicted to triple by 2050 unless disease-modifying ....Targeting brain lipid homeostasis to treat Alzheimer's disease. Dementia affects approximately 250,000 people in Australia at an estimated cost (in 2002) of $6.6 billion per annum. The major cause of dementia (accounting for approximately 70% of all cases) is Alzheimer's disease (AD); a progressive neurodegenerative illness for which there is no curative or disease-stalling treatment. Due to increases in life expectancy, the incidence of AD is predicted to triple by 2050 unless disease-modifying treatments are developed. This research program will provide novel realistic pharmaceutical approaches to treat AD. Even if the onset of AD could be delayed by a few years the personal and financial benefits would be enormous. The potential for this research to generate commercially viable Australian intellectual property is also significant.Read moreRead less
Unravelling the mechanism of vesicular docking in neurosecretory cells. The fusion of secretory vesicles (SVs) by exocytosis underpins neuronal and hormonal communication. The aim of this project is to unravel all the steps bringing these vesicles to the plasma membrane where they dock. Specifically, we aim to unravel the role for the cytoskeleton in creating an interface where SV confinement leads to the appropriate pairing of molecules mediating the fusion between the vesicles and the plasma m ....Unravelling the mechanism of vesicular docking in neurosecretory cells.

This proposal will address a major gap in our mass spectrometry capabilities and aid in our understanding of protein interactions and tissue distribution in areas such as neuroscience, microbiology, immunology, and botany, as well as enhance our understanding of fundamental gas phase chemistry of protein molecules. It brings together a highly successful multidisciplinary team of high-profile researchers with a track record of collaboration and delivering outcomes from shared facilities. In addition to these key scientific outcomes this project will also facilitate the training of several new personnel in a skill area for which there is a critical shortage (mass spectrometry) and promote true cross-disciplinary skills.Read moreRead less
Biomagnification of the biotoxin BMAA in the environment. Using unique models and technics, the project aims to demonstrate that long-term exposure to the blue green algae toxin β-N-methylamino-l-alanine (BMAA) leads to uptake, accumulation and toxicity within the central nervous system. The risks for heath, mechanisms of contamination and toxicity of BMAA are very poorly understood.

The risks for heath, mechanisms of contamination and toxicity of BMAA are very poorly understood. Algal blooms cost the Australian community more than $250 million each year and represent a major health issue for human and fauna. This project aims to be the first to fully characterise BMAA mechanisms of contamination and neurotoxicity and to highlight the major environmental risk of exposure of human to BMAA. It also aims to develop new and unique detection and quantification tools for BMAA.Read moreRead less
The role of actin in driving bulk endocytosis in neurons and neurosecretory cells. Synaptic release of neurotransmitter is essential for neuronal communication. Following fusion, synaptic vesicle membrane is incorporated into the plasma membrane and retrieved by endocytosis to recover both lipids and essential vesicular proteins. The project will characterise how the actin cytoskeleton perform this function.

A cryosystem installed at USyd. will provide a massive boost in productivity and will allow projects previously inaccessible due to excessive turn-around times, or sensitivity or solubility problems to become tractable. This system will provide new opportunities to researchers from USyd., UNSW and ANU, but will restrict the versatility of the USyd. instrument. The installation of a TBI probe at UNSW will counter this, and provide a REAL network of NMR instruments across NSW and the ACT.Read moreRead less
The role of tropomyosin in coordinated neurite branching. This project will explore how nerve cells generate a highly branched network of cell processes which allows all higher functions of the nervous system. We previously discovered the central role of a component of the cell architecture in determining the branching pattern and in this project expect to reveal the molecular basis for its function.
