Subcellular recruitment of a RhoA ubiquitination complex by Rnd proteins. This study addresses a novel molecular mechanism through which members of the Rnd family of GTP-binding proteins regulate the morphology and migration of immature nerve cells of the developing nervous system. This study has broad implications for the understanding of cell migration during embryo development, as well as in health and disease.
Modelling human brain development with stem cells and biomaterials. With limited resources to directly study and advance our understanding of human neural development, this
proposal will establish models of 4 key stages. Employing innovative, interdisciplinary approaches, biomaterials will be fabricated to provide structural and chemical support for human stem cells during: (i) neural induction, (ii) specification into neuronal progenitor subpopulations, (iii) neuronal maturation and integration ....Modelling human brain development with stem cells and biomaterials. With limited resources to directly study and advance our understanding of human neural development, this
proposal will establish models of 4 key stages. Employing innovative, interdisciplinary approaches, biomaterials will be fabricated to provide structural and chemical support for human stem cells during: (i) neural induction, (ii) specification into neuronal progenitor subpopulations, (iii) neuronal maturation and integration into complex neural networks as well as, (iv) the organisation of neurons into larger 3-dimensional brain structures, namely folding of the human cortex. Further, biomaterials developed here have commercialisation potential, targeted at standardizing the culturing of human stem cells to defined neural populations.

Modelling the human nervous system with human pluripotent stem cells. The human nervous system is one of the most complex structures evolved to date. In order to understand how it functions, and dysfunctions in a diseased state, it is fundamental to decipher how it develops to generate various neuronal populations that form this elaborate network. Human stem cells provide a valuable source to study such processes. The aim of this project is to use human stem cells to study how early progenitor c ....Modelling the human nervous system with human pluripotent stem cells. The human nervous system is one of the most complex structures evolved to date. In order to understand how it functions, and dysfunctions in a diseased state, it is fundamental to decipher how it develops to generate various neuronal populations that form this elaborate network. Human stem cells provide a valuable source to study such processes. The aim of this project is to use human stem cells to study how early progenitor cell types that structure the nervous system are generated and how their neuronal derivatives form connectivity and functional synapses. The outcome of these studies is that we will establish a cellular model of human neurogenesis that can be utilised to study developmental disease processes.Read moreRead less
A toxic cycle of inflammation and iron in the ageing brain. This project investigates why our brain cells gradually die as we grow older. We believe that infections and inflammation in other parts of the body cause iron to accumulate in the brain and become toxic. Iron supplements and ageing may make this situation worse. The results of this study could lead to new treatments for memory loss and dementia.
Delineating the functional role of the amyloid precursor protein's copper binding domain. This study will define how the interaction between copper and the amyloid precursor protein (APP) molecule regulates copper homeostasis and APP metabolism. Since copper homeostasis is tightly regulated and vital for normal cellular function, understanding the regulation copper homeostasis is important for basic biology. Moreover, APP is directly involved in causing Alzheimer's disease and therefore underst ....Delineating the functional role of the amyloid precursor protein's copper binding domain.

Since copper homeostasis is tightly regulated and vital for normal cellular function, understanding the regulation copper homeostasis is important for basic biology. Moreover, APP is directly involved in causing Alzheimer's disease and therefore understanding the interaction between APP and copper has potential benefits for community health by combating aging and Alzheimer's disease.Read moreRead less

Brain and Behaviour Network. The Brain and Behaviour Network is concerned with understanding the underlying mechanisms which determine how we behave. It encompasses many disciplines including anthropology, education, ethology, neurology, neuroscience, philosophy and psychology. The Network will bring these disciplines together to create a forum to discuss and integrate the knowledge into a framework for understanding the mechanisms of behaviour and to stimulate cross-disciplinary research.

It encompasses many disciplines including anthropology, education, ethology, neurology, neuroscience, philosophy and psychology. The Network will bring these disciplines together to create a forum to discuss and integrate the knowledge into a framework for understanding the mechanisms of behaviour and to stimulate cross-disciplinary research. The framework of knowledge will lead to a greater understanding of how we behave and will improve knowledge in areas which have a major behavioural component, such as in human development and education, psychological well-being, psychiatric problems and ageing.Read moreRead less
Targeting Necroptosis Signalling To Counter Stroke-induced Brain Injury

Funding Amount

Summary
The origins of the brain injury that arises from stroke remain a matter of enormous interest. Our work suggests that a poorly understood form of cell death, termed necroptosis, contributes to injury to the brain following stroke. In addition to developing an advanced understanding of this process, we will use drugs developed at the Walter and Eliza Hall Institute to test whether blocking this process might be a plausible therapeutic strategy in stroke patients.
Selective Isolation And In Vivo Properties Of Dopamine Neurons Generated From Embryonic Stem Cells.

Funding Amount
$505,389.00
Summary
This research aims to develop a procedure that allows for the safe and effective use of stem cells as a therapy for Parkinson’s disease. It is based on the concept that new dopamine neurons, generated from stem cells, can be implanted into the brain of the patients in order to replace those lost to the disease, thereby improving motor function.
The Role of Amyloid Protein Precursor in Mammalian Copper Transport. The knowledge gained from this investigation will help us to develop new medicines for the treatment of debilitating and ever more prevalent age-related neurodegenerative diseases and will help us to illuminate the role of metals in the ageing process itself. Apart from the obvious economic and social benefits in extending the productive lifetime of its citizens, the outcomes of this project have clear commercial applications. ....The Role of Amyloid Protein Precursor in Mammalian Copper Transport.

Apart from the obvious economic and social benefits in extending the productive lifetime of its citizens, the outcomes of this project have clear commercial applications. We anticipate that there will be patents that will ensue from the programme, which will be licensed to Australian interests, and contribute to the national revenue in the biotechnology and pharmaceutical sector.Read moreRead less
Neural Copper Homeostasis: the role of the Alzheimer Amyloid-beta Precursor Protein. Alzheimer's disease (AD) is creating a growing burden upon Australian medical resources. Copper plays an important role in the development of AD, and drugs designed to adjust brain copper levels are being tested for AD treatment and show therapeutic benefits. This project will determine how copper is involved in AD so that more effective drugs can be developed.

Alzheimer's disease (AD) is creating a growing burden upon Australian medical resources. Copper plays an important role in the development of AD, and drugs designed to adjust brain copper levels are being tested for AD treatment and show therapeutic benefits. This project will determine how copper is involved in AD so that more effective drugs can be developed. Focus will primarily be on copper-binding proteins central to AD, including amyloid-beta, and their role in AD development. Upon completion of this project, we expect to better understand neural copper metabolism in health and in AD pathology, with outcomes directly applicable to therapeutic AD intervention.Read moreRead less
