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 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
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.

Summary
Regeneration of the central nervous system following disease or injury is extremely limited and frequently results in substantial impairment. A potential therapy to replace damaged or killed nervous system cells is the use of neural stem cells. Neural stem cells are present in the central nervous system and frequently attempt, but fail to repair nervous system damage. This project aims to examine factors that regulate neural stem cell function including factors that may regulate their ability to ....Regeneration of the central nervous system following disease or injury is extremely limited and frequently results in substantial impairment. A potential therapy to replace damaged or killed nervous system cells is the use of neural stem cells. Neural stem cells are present in the central nervous system and frequently attempt, but fail to repair nervous system damage. This project aims to examine factors that regulate neural stem cell function including factors that may regulate their ability to migrate or become appropriate neural cell types. Of particular interest are factors known as chemokines that regulate cell migration as well as have a variety of other effects. In addition, interferons, which are inflammatory molecules present in the damaged nervous system and that we have shown affect neural stem cell function, may interact with chemokines and will also be examined. In addition to examining the effects of these factors on neural stem cells, the signalling pathways they use in these cells will also be determined.Read moreRead less
Transcriptional control of neural stem cell differentiation during development and disease. Understanding the molecular mechanisms that control how neural stem cells differentiate is critical to provide potential therapeutic treatment for neurodegenerative diseases and for brain cancer. This project will aim to discover, using an animal model system, the genes and molecules regulating these key biological processes.

The equipment requested will facilitate the work of the Australian Mouse Brain Mapping Consortium, a consortium of Australian research groups collaborating to provide the only mouse model brain mapping capability in the country. The consortium brings together laboratory, neuroimaging and computational expertise in a comprehensive framework for imaging the mouse brain. This will help researchers to study mouse models of genetic and acquired disorders across the life-span. Remote viewing and analysis capabilities will help overcome the 'tyranny of distance', increasing national access to the facility. Repositories of digitised images will increase the availability of valuable research material to other Australian and international researchers.Read moreRead less

Summary
This project uses imaging techniques and molecular genetics to produce the next generation of brain maps. It will advance our understanding of the organisation and structure of the brain and spinal cord of humans and experimental animals – paving the way for the development of psychotherapeutic drugs and more accurate interventions on the human brain. The new maps will help those who study the brain of patients with diseases such as Alzheimer’s or Parkinson’s or animal models of these diseases.
Cellular and Neurochemical Basis of Drug Addiction. Addiction to the major drugs of abuse, including heroin, amphetamines, cocaine, nicotine and alcohol damage the lives and cause premature death of more than 20% of Australians. Addiction produces long-term disruption of brain processes that lead to loss of control over urges to consume drugs and persistent cycles of relapse to drug taking. This research will apply new neurochemical approaches to discover mechanisms of disrupted brain function t ....Cellular and Neurochemical Basis of Drug Addiction.

Addiction produces long-term disruption of brain processes that lead to loss of control over urges to consume drugs and persistent cycles of relapse to drug taking. This research will apply new neurochemical approaches to discover mechanisms of disrupted brain function that occur during development of addiction and relapse that are critical for development of better strategies to treat the disorder.

Central pathways regulating visceral pain. This project aims to investigate the neural pathways within the spinal cord and brain processing colorectal pain perception. The project aims to identify the spinal cord neurons relaying colorectal signalling into the brain and the influence of descending modulation from the brainstem upon these pathways. The outcomes will greatly benefit fundamental understanding of the central pathways processing visceral pain.
