Alzheimer's, Huntington's and Parkinson's diseases involve the formation of protein aggregates, termed amyloid. The formation of amyloid leads to cell death and neurodegeneration. The most important cellular events perturbed by the formation of amyloid aggregates are unclear. Recent evidence suggests that sterols (including cholesterol) have an important role in cellular toxicity. This study will examine the molecular basis for this, enhancing our understanding of the amyloid diseases and could ....Alzheimer's, Huntington's and Parkinson's diseases involve the formation of protein aggregates, termed amyloid.

Unraveling The Dynamic Munc18a:Syntaxin1 Interaction Required For Neurotransmission
Funder
National Health and Medical Research Council
Funding Amount
$674,591.00
Summary
Membrane trafficking, the topic of the 2013 Nobel prize in Medicine, is required for delivery of cellular cargo. This research will investigate the interactions and structures of proteins from the neuronal membrane trafficking system. Understanding how this system operates will expand our knowledge of processes fundamental to learning and memory and may ultimately lead to development of selective therapeutics for treating a range of diseases.
Mechanisms Of Gene Regulation - Structure, Function And Design
Funder

Funding Amount
$697,209.00
Summary
The human genome contains at least 20000 genes. The activity of these genes must be tightly controlled throughout an individual’s life and problems with the regulation of genes lie at the heart of many common and serious diseases, including most forms of cancer. My program of research is focused on understanding the mechanisms underlying gene regulation and on the design of new reagents that could be used to manipulate the activity of genes that behave aberrantly in disease states.
Design And Engineering Of Adnectins For Diagnosis And Therapy
Funder
National Health and Medical Research Council
Funding Amount
$803,152.00
Summary
This project aims to engineer a naturally-occurring human protein, called an adnectin, to produce molecules that are able to bind specific targets in the human body, and as such may be used in the diagnosis and therapy of a range of diseases.
Characterization Of The Type IX Secretion System In Porphyromonas Gingivalis

Funding Amount

Summary
Periodontitis is associated with the keystone pathogen Porphyromonas gingivalis. We have identified a novel protein secretion machine comprised of at least 12 components in P. gingivalis which transports the bacterium's major virulence factors to the cell surface and attaches them to the outer membrane. We aim to determine the spatial arrangement and specific role of each of these 12 components and thereby provide targets for future treatments against this disease.
