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
Regulation of neuronal cell death signalling for the treatment of neurodegenerative diseases. The progression of neurodegenerative diseases, such as Alzheimer's and motor neuron diseases, are often underpinned by neuronal cell death-signalling. This project aims to characterise molecules that regulate cell death signalling, thereby increasing our knowledge of how neuronal cell death can be inhibited.

Summary
The regulation by transcription factor phosphorylation upon the myelinating process. The project will investigate the novel molecular events that control the myelinating process, which is essential for normal nervous system function. Outcomes of this project may aid the development of novel interventions to improve control of demyelinating diseases, which represent a substantial socio-economic burden.
Development of novel reagents that specifically counteract EphA4 to enhance axonal regeneration. This project will examine the role of EphA4, an important guidance protein, in neural cell regeneration. The goal is to understand the signalling mechanisms that inhibit regeneration in the central nervous system and to develop novel biological agents to overcome these processes and promote functional recovery after nervous system injury or disease.
Characterisation Of Eurl, A Novel Gene Implicated In The Etiology Of Abnormal Brain Development And Intellectual Disability

Funding Amount
$597,541.00
Summary
Intellectual disability affects around one per cent of Australians, and can arise from genetic abnormalities during fetal life, such as through abnormal regulation of gene expression. We have identified a novel gene, known as eurl, which controls brain assembly as well as the ability of neurons to form functional connections within the brain. We will investigate how this novel gene controls brain development, and characterise eurl as a potential therapeutic target for learning and memory.
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 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 that occur during development of addiction and relapse that are critical for development of better strategies to treat the disorder.

Electrical activity in early enteric neuron development. Intestinal movements and secretion are critical to the good health and nutrition of both humans and animals. These functions are regulated by a large nervous system contained within the intestinal wall, the enteric nervous system. This project will identify how enteric nerve cells develop and how their behaviour influences the development of other enteric nerve cells. This is will provide an important base for more applied research aime ....Electrical activity in early enteric neuron development. Intestinal movements and secretion are critical to the good health and nutrition of both humans and animals. These functions are regulated by a large nervous system contained within the intestinal wall, the enteric nervous system. This project will identify how enteric nerve cells develop and how their behaviour influences the development of other enteric nerve cells. This is will provide an important base for more applied research aimed at developing treatments for diseases like chronic constipation and irritable bowel syndrome. It will also contribute to the growing knowledge about how epigenetic factors can modify genetically programmed development within the nervous system.Read moreRead less
Cell cycle and enteric neuron and glial differentiation. Enteric neurons arise from a very small starting population of precursor (neural crest) cells, most of which emigrate from the hindbrain, and colonise the developing gut. Over a protracted period of time the precursors proliferate and differentiate into glia and many different types of neurons. Cell cycle exit is a critical event in the development of many neuron types, largely because the time at which cells exit from the cell cycle lim ....Cell cycle and enteric neuron and glial differentiation. Enteric neurons arise from a very small starting population of precursor (neural crest) cells, most of which emigrate from the hindbrain, and colonise the developing gut. Over a protracted period of time the precursors proliferate and differentiate into glia and many different types of neurons. Cell cycle exit is a critical event in the development of many neuron types, largely because the time at which cells exit from the cell cycle limits the number of neurons that will be generated. We will determine whether exit from the cell cycle contributes to the differentiation and specification of enteric neurons and glia.Read moreRead less
Gene-environment interactions mediating experience-dependent plasticity in the healthy and diseased brain. The aim of this project is to understand how genes and environment combine to affect susceptibility to various brain disorders, using models of human diseases and manipulating environmental factors such as mental and physical activity. The project's focus is on neurological and psychiatric disorders, including Huntington's disease, depression, schizophrenia and autism.
