Assessing the physiological roles of ubiquitination in regulating neuronal ion channels, receptors and transporters. Significant alterations in the activity neuronal transporters and receptors occur during tissue injury and regeneration as well as in many neurodegenerative disease states. Modulation of the pathways that control these transporters is an emerging therapeutic target, however, the molecular basis of these control mechanisms remain poorly understood.

Significant alterations in the activity neuronal transporters and receptors occur during tissue injury and regeneration as well as in many neurodegenerative disease states. Modulation of the pathways that control these transporters is an emerging therapeutic target, however, the molecular basis of these control mechanisms remain poorly understood. The outcome of this project will be a thorough characterisation of a novel regulatory paradigm in neurons that is likely to be crucial for neuronal development and regeneration, and will potentially provide novel therapeutic targets for various neuronal diseases.Read moreRead less

Summary
The timely differentiation of neural stem cells is critical during development, and the unrestrained proliferation of neural stem cells in the adult can lead to deadly brain cancers such as glioma. At present our understanding of the key molecules that regulate neural stem cell behaviour during these processes remains limited. In this proposal we will investigate the molecular determinants underpinning neural stem cell biology, both within the developing brain, and within glioma.
The processing of sensory information within cortical circuits. This project aims to improve our knowledge of neuronal activity during sensory perception and therefore shed light on overall brain function during behaviour. Understanding how dendrites receive and process this information is crucial to understanding brain function during sensory processing and perception.

This project aims to improve our knowledge of neuronal activity during sensory perception and therefore shed light on overall brain function during behaviour. Understanding how dendrites receive and process this information is crucial to understanding brain function during sensory processing and perception. This proposal aims to characterise dendritic activity during sensory input and discover how this activity contributes to behavioural tasks. In particular, the project plans to investigate activity of different dendritic domains during sensory perception and sensory-based behaviour. The project seeks to improve our knowledge of the importance of dendrites in transforming information from the sensory environment and highlight the cellular and network mechanisms contributing to behaviour.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.
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.

Summary
Proper foetal brain assembly is critical for brain function, but the underlying genetic mechanisms remain poorly defined. In this study, I will investigate a family of proteins that “turn on” neural gene expression in combination with another protein that “turns off” their expression during nerve cell development. Understanding this novel on/off mechanism for controlling gene expression in newborn nerve cells will further our understanding of how the brain is assembled.
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.

Gene-environment interactions in the regulation of neuroplasticity and cognitive function . This project will study the effects of different housing conditions on neuroplasticity-related cognitive function by combining an innovative operant conditioning behavioural test (computerised touch-screen technology) and new molecular approaches. Potential gene-environment interactions will be revealed using genetically targeted mice which have never been assessed in that context (mutants with altered gl ....Gene-environment interactions in the regulation of neuroplasticity and cognitive function . This project will study the effects of different housing conditions on neuroplasticity-related cognitive function by combining an innovative operant conditioning behavioural test (computerised touch-screen technology) and new molecular approaches. Potential gene-environment interactions will be revealed using genetically targeted mice which have never been assessed in that context (mutants with altered glucocorticoid and serotonin signalling). This project will study whether specific stages of the neuroplasticity process are differentially modulated through gene-environment interactions, ultimately resulting in changes to behaviour and cognitive functions. This will lead to a better understanding of the potential approaches that could be used to improve cognitive function.Read moreRead less
The long-term consequences of toluene exposure on the maturing brain. Inhalant abuse is a significant problem especially among adolescent and indigenous communities. This project will provide insights into the long-term neurobiological consequences following inhalant exposure during adolescence when critical aspects of brain development are still occurring and how these may relate to altered behaviour in adulthood.
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.

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
