The Genetic Analysis of Neurological Diseases. Multiple sclerosis and Parkinson's are debilitating neurodegenerative diseases, which affect 16,000 and 80,000 Australians, respectively. Between them, these diseases cost the community $7.8 billion per annum, and there is no cure. This proposal will study the genes that influence a person's predisposition to developing these diseases, and what makes some people have particular characteristics. It will provide novel insights into the diseases themse ....The Genetic Analysis of Neurological Diseases. Multiple sclerosis and Parkinson's are debilitating neurodegenerative diseases, which affect 16,000 and 80,000 Australians, respectively. Between them, these diseases cost the community $7.8 billion per annum, and there is no cure. This proposal will study the genes that influence a person's predisposition to developing these diseases, and what makes some people have particular characteristics. It will provide novel insights into the diseases themselves and information that could help in the development of new and more effective drugs, and biomarkers to assist in the prediction of prognosis. Such advances would decrease the economic impact of these diseases and improve quality of life for those affected.Read moreRead less
Investigating the role of the innate immune complement system in the abnormal development of the central nervous system. Past research has discovered a surprising link between the immune system, dietary folate deficiency and the development of the embryonic brain. This project will investigate the immune system in the developing brain, in order to understand the causes of developmental defects such as neural tube defects, and the role dietary folate plays in this process.
Investigating the neuroprotective actions of metallo-complexes. Metal-based drugs offer an exciting new approach to treatment of neurodegeneration. However, little is known about how cells metabolise these drugs: information that is critical for further drug development. This project will determine how metal-based drugs are metabolized by neuronal cells and how this may result in therapeutic benefit.
Understanding the contribution of neuroinflammation in acute and chronic neural injury. A major focus of this project will be investigating the involvement of neuroinflammation in neural cell damage. It will explore how neuroinflammation contributes to this damage in both acute and chronic neuropathologies.
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
How the gut nervous system interacts with bacteria. This project aims to reveal how the enteric nervous system of the gastrointestinal (GI) tract interacts with the gut microbiota. Gut function has largely been studied without considering microbiota. The project will use genetically modified animal models, image analysis of gut motility and sequencing of gut microbes, and develop neurophysiological methods to understand gut function. Expected benefits include better understanding of mechanisms u ....How the gut nervous system interacts with bacteria. This project aims to reveal how the enteric nervous system of the gastrointestinal (GI) tract interacts with the gut microbiota. Gut function has largely been studied without considering microbiota. The project will use genetically modified animal models, image analysis of gut motility and sequencing of gut microbes, and develop neurophysiological methods to understand gut function. Expected benefits include better understanding of mechanisms underlying antibiotic resistance, risks associated with discretionary caesarean sections and the benefits of breastfeeding.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.
Pontine control of adaptive breathing behaviour in health and disease. This project will develop an understanding of the fundamental brain mechanisms associated with adaptive breathing during behaviour such as speech or swallowing. Adaptive breathing is impaired in lung disease, dementia and autism. This project will provide new insight to global brain function and treatment of central respiratory disorder.
The role of P2X7 and P2X4 receptor mediated innate phagocytosis in pathogenesis and treatment of neurodegenerative diseases. This project will identify how inherited variation in two proteins of the brain can accelerate the removal of neurones and predispose to a range of neurodegenerative diseases. Knowledge of the biological basis of this finding will allow a search for new compounds which will slow and protect against this form of neurodegeneration.
Psychiatric disorders in epilepsy. Psychiatric disorders, such as depression, anxiety and cognitive disorders, are frequently observed in patients with epilepsy. Although standard dogma suggests that psychiatric disorders are a consequence of living with epilepsy, recent evidence suggests a bidirectional relationship between these disorders, such that depression and other psychiatric illnesses act as risk factors for epilepsy development. This project will utilise basic science approaches to und ....Psychiatric disorders in epilepsy. Psychiatric disorders, such as depression, anxiety and cognitive disorders, are frequently observed in patients with epilepsy. Although standard dogma suggests that psychiatric disorders are a consequence of living with epilepsy, recent evidence suggests a bidirectional relationship between these disorders, such that depression and other psychiatric illnesses act as risk factors for epilepsy development. This project will utilise basic science approaches to understand the causal relationships between epilepsy and psychiatric disorders, and determine how and why psychiatric disorders and epilepsy co-exist. It is hoped that research conducted in this project will develop novel avenues to treatment of both epilepsy and psychiatric disorders.Read moreRead less
