Summary
The strength of communication between each nerve cell in the brain depends on how active that nerve cell has been. This enables the brain to be adaptable and is a way for the brain to set up circuits that underlie how we learn and remember. More or less release of chemical messengers (neurotransmitters) into nerve cell junctions changes the strength of nerve cell communication. We have discovered a new chemical signalling pathway controlling neurotransmitter release.

Summary
Essentially all of the body's functions from muscle contraction, energy expenditure through to appetite are controlled by a complex molecular communications system. One of the key elements involves the modification of proteins to alter their properties by adding and removing phosphate. By analysing this process in response to diet and exercise we will obtain a greater understanding of their health benefits and understand how type 2 diabetes and obesity develop at the molecular level.
Inhibitory Signalling Switches Define The Machinery Of Synaptic Vesicle Endocytosis

$387,489.00
Summary
The nerve cells in our brains are in constant communication to sustain life. Communication involves one nerve cell responding to electrical stimulation by releasing chemical messengers, from vesicles, onto the next cell. Our research focuses on the mechanism of recycling of vesicles. Targeting this mechanism is a way to gain fundamental knowledge of how to intervene medically when communication fails, or when communication needs to be dampened, in neurological diseases.
The Role Of Stargazin And TARP Phosphorylation In Synaptic Plasticity

Summary
A constant change in the strength of synaptic communication between neurons is critical for higher brain functions such as learning and memory. Synaptic strength is determined in part by the number of receptor ion channels at the synapse. This project will characterise how key interacting proteins regulate the synaptic targeting of these receptors in vivo. This research aims to understand the mechanisms of synaptic plasticity that may ultimately lead to new therapies for various brain disorders.

Summary
PTEN mutations are frequently described in various types of cancer. This proposal outlines different experimental strategies to probe how modulation of distinct PTEN functions can affect signalling pathways and be responsible for oncogenic outcomes. We will use animal models and cell lines in culture to identify new signatures/biomarkers to stratifying patients on genetic and molecular bases, and to facilitate the design of tailored combinational therapies directed toward cancer eradication.

Summary
The nerve cells in our brains are in constant communication to sustain life. Communication involves electrical stimulation of one nerve cell which then responds by releasing chemical messengers, from vesicles, onto the next cell. Our research focuses on the mechanism of recycling of vesicles. Targeting this mechanism is a way to gain fundamental knowledge of how to intervene medically when communication fails, or when communication needs to be dampened, such as in some neurological diseases.

Dental caries (tooth decay) remains a major public health problem in Australia with an economic burden in excess of $1 billion p.a. The overall aim of this project is the development of a novel remineralizing agent (casein phosphopeptide stabilized amorphous calcium fluoride phosphate) for the remineralization of early tooth decay lesions (white spot lesions).

The overall aim of this project is the development of a novel remineralizing agent (casein phosphopeptide stabilized amorphous calcium fluoride phosphate) for the remineralization of early tooth decay lesions (white spot lesions). The project will involve the testing of the ability of the novel remineralization system to remineralize (repair) white spot lesions in vitro and in situ. The project also involves the detailed characterization of the molecular interactions of the components of the remineralizing system using NMR spectroscopy and other techniques. It is anticipated that this project will result in the development of a system with substantialy superior properties for the non-invasive treatment (reversal) of white spot lesions and may ultimately lead to the development of a novel system for the treatment and prevention of tooth decay.Read moreRead less

Summary
Tooth decay remains a major public health problem. The project will involve the testing of the system to remineralize (repair) early stages of decay in the laboratory. The project also involves the detailed characterization of the molecular interactions of the components of a system. It is anticipated that this project will result in the development of a system with substantialy superior properties for the non-invasive treatment (repair) of early tooth decay.
