Novel mechanisms integrating the central and autonomic nervous system. This project aims to define molecular mechanisms controlling the exquisite connectivity of neurons in different parts of the body. The ability of higher-vertebrates to respond to different environmental conditions is essential for life, evolution, health, reproduction and growth, and is reliant on the autonomic nervous system. However, how the autonomic nervous system is integrated with the central nervous system to control h ....Novel mechanisms integrating the central and autonomic nervous system. This project aims to define molecular mechanisms controlling the exquisite connectivity of neurons in different parts of the body. The ability of higher-vertebrates to respond to different environmental conditions is essential for life, evolution, health, reproduction and growth, and is reliant on the autonomic nervous system. However, how the autonomic nervous system is integrated with the central nervous system to control holistic physiological responses is largely unknown. By deciphering how neural networks are formed this project aims to provide broad biological insight to wiring of the entire nervous system which is likely to have significant implications for the formation of synthetic neural networks and for regeneration.Read moreRead less
How Spinal Afferent Neurons Control Appetite and Thirst . This project aims to provide major new insights about how the gut communicates with the brain, to regulate how much food and fluids have been consumed. The proposal expects to generate new knowledge about gut-brain communication and how one of the major sensory nerves from the gut relays information about thirst and appetite sensations. The project addresses fundamental questions that rely on techniques only recently developed in our labo ....How Spinal Afferent Neurons Control Appetite and Thirst . This project aims to provide major new insights about how the gut communicates with the brain, to regulate how much food and fluids have been consumed. The proposal expects to generate new knowledge about gut-brain communication and how one of the major sensory nerves from the gut relays information about thirst and appetite sensations. The project addresses fundamental questions that rely on techniques only recently developed in our laboratory. We expect to demonstrate a major new sensory nerve pathway from the gut to the brain that plays a major role in appetite and thirst sensations. We will learn how gut to brain communication underlies the feeling of "fullness" when people consume food and drink.

Understanding gender differences in pain: Cellular therapies for animal pain. Understanding gender differences in pain: Cellular therapies for animal pain. This project aims to relieve chronic pain in animals and lay the foundations for future human therapies, using molecular assays, cell technologies and immune/hormonal pain generators. Chronic pain affects females more than males. Establishing the fundamental mechanism in pain, the role of immune signalling and molecular mediators will enable ....Understanding gender differences in pain: Cellular therapies for animal pain. Understanding gender differences in pain: Cellular therapies for animal pain. This project aims to relieve chronic pain in animals and lay the foundations for future human therapies, using molecular assays, cell technologies and immune/hormonal pain generators. Chronic pain affects females more than males. Establishing the fundamental mechanism in pain, the role of immune signalling and molecular mediators will enable true pain-modifying treatments that address pivotal triggers in both genders. This project will then use specially selected stem cells separately targeting arthritic male and female pain and demonstrate novel veterinary chronic pain treatments. Expected outcomes are more effective gender-targeted treatments of pain and the realisation of economic value of molecular assays and cell technologies.Read moreRead less
How do protein quality control mechanisms maintain neuronal ageing? This project aims to interrogate how mechanisms of protein quality control act in the brain - an organ that is particularly vulnerable to a high load of misfolded protein - to maintain normal physiology during ageing. This project expects to make advances in cellular biochemistry and neuroscience, using an innovative proximity labelling approach to identify quality control regulators in neurons that specifically engage with misf ....How do protein quality control mechanisms maintain neuronal ageing? This project aims to interrogate how mechanisms of protein quality control act in the brain - an organ that is particularly vulnerable to a high load of misfolded protein - to maintain normal physiology during ageing. This project expects to make advances in cellular biochemistry and neuroscience, using an innovative proximity labelling approach to identify quality control regulators in neurons that specifically engage with misfolded proteins during ageing, within the nervous system of a living animal. Expected outcomes of this project will generate new knowledge of brain physiology and ageing relevant to all animals. This should provide significant benefits, such as a greater understanding of long-term brain functions including memory.Read moreRead less
Huntingtin-associated protein 1 controls cell communication. The purpose of this study is to identify the mechanisms by which a novel regulator of cell communication which we have identified is able to control the release of chemical signals from a cell. This project will provide critical insight into a cellular pathway that underlies hormone secretion, neurotransmission and higher brain functions.
Cellular bases of enteric neural circuitry underlying gut propulsion. This project aims to investigate the neural bases of behaviour in the mammalian gut. The Enteric Nervous System (ENS) plays a critical role in the propulsion of intestinal contents. This project expects to establish how specific functional classes of enteric neurons control propulsion along the gut. By recording the simultaneous neural activity from hundreds of different functional classes of enteric nerve cells simultaneously ....Cellular bases of enteric neural circuitry underlying gut propulsion. This project aims to investigate the neural bases of behaviour in the mammalian gut. The Enteric Nervous System (ENS) plays a critical role in the propulsion of intestinal contents. This project expects to establish how specific functional classes of enteric neurons control propulsion along the gut. By recording the simultaneous neural activity from hundreds of different functional classes of enteric nerve cells simultaneously, whilst recording intestinal muscle electrical activity and the movements of the gut wall, the project expects to identify which enteric neurochemical classes of neurons generate specific motor patterns along the intestine.Read moreRead less
