Summary
Dyspepsia, unexplained stomach discomfort and pain, is a common and costly problem; few effective treatments exist and the causes are unknown. We have found that the numbers of a type of immune cell, the eosinophil, are increased in the top of the small bowel in patients with dyspepsia. This study will explore the mechanisms that lead to increased eosinophils and then test the effectiveness of a treatment to suppress this overactive immune response which could rapidly change clinical practice.
Tolerising Antigen-specific Immunotherapy For Type 1 Diabetes

Summary
We have developed a new immunotherapy to treat the underlying causes of type 1 diabetes (T1D) while leaving the rest of the immune system intact. To use this in patients, we need better tests to know when immune therapy is working. We will develop new methods to design the therapy and tools to track the relevant immune cells in T1D that work in variable patient groups. The knowledge gained will speed the pace of development and increase the chance of success of immunotherapy in T1D.
A Novel Role For The IL-2 Pathway In Type-1-diabetes.

Summary
Genes encoding IL-2 and its receptor are strongly linked to susceptibility to multiple autoimmune diseases, including type-1-diabetes. Despite the importance of this pathway in the immune system, it is not yet understood how the associated genes affect disease. In this study, a novel function for IL-2 expression by dendritic cells in normal self-tolerance is investigated. The impacts of dendritic cell produced IL-2 expression and linkage to autoimmunity will be elucidated in both mouse and man.
A lipodomic approach to cnidarian-dinoflagellate symbiosis. Fatty Acids are essential for human health and for reef health. This lipodomic study using newly developed techniques, aims to understand the essential and non-essential fatty acid metabolic exchange in the symbiosis that drives coral reef formation and health, and in turn gives reflective insight into our own metabolism.
The role of actin in driving bulk endocytosis in neurons and neurosecretory cells. Synaptic release of neurotransmitter is essential for neuronal communication. Following fusion, synaptic vesicle membrane is incorporated into the plasma membrane and retrieved by endocytosis to recover both lipids and essential vesicular proteins. The project will characterise how the actin cytoskeleton perform this function.
A novel click chemistry approach to identify learning and memory molecules. This project seeks to contribute to a deeper understanding at a molecular level of how memory is stored in neurons. Long-term memories do not form immediately after learning. Initially fragile, they become resistant to disruption through a process known as memory consolidation. In a second process, termed reconsolidation, pre-established memories are updated and re-stored. Both processes depend on protein synthesis, but ....A novel click chemistry approach to identify learning and memory molecules. This project seeks to contribute to a deeper understanding at a molecular level of how memory is stored in neurons. Long-term memories do not form immediately after learning. Initially fragile, they become resistant to disruption through a process known as memory consolidation. In a second process, termed reconsolidation, pre-established memories are updated and re-stored. Both processes depend on protein synthesis, but little is known about the particular sets of proteins that are involved. The project plans to apply a novel biochemical protocol to a newly established transgenic mouse model that allows the visualisation and identification of newly synthesised proteins in the hippocampus, a brain area that is critical in memory formation.Read moreRead less
Understanding specificity and flexibility in coral symbioses. This project aims to understand why some corals can switch algal partners while others remain faithful to a single strain. This is important because corals depend on their symbiotic algal partners for survival and because some algae provide greater resilience to environmental stress than others. This project will greatly enhance our understanding of the molecular and physiological factors governing flexibility and specificity in coral ....Understanding specificity and flexibility in coral symbioses. This project aims to understand why some corals can switch algal partners while others remain faithful to a single strain. This is important because corals depend on their symbiotic algal partners for survival and because some algae provide greater resilience to environmental stress than others. This project will greatly enhance our understanding of the molecular and physiological factors governing flexibility and specificity in coral-algal symbioses. It will provide much-needed knowledge required to identify associations most appropriate for specific conditions, prioritise populations for conservation, and assess the feasibility of new approaches to managing and restoring coral reefs.

Understanding how an old heart gets stiff. Aging is accompanied by a stiffening of the heart and reduced function, which is accelerated by cardiovascular disease and leads to heart failure. How the heart stiffens is poorly understood. A new mechanism is proposed here, involving structural membrane proteins (termed caveolae and cavins) and a signalling molecule (nitric oxide). The current research aims to unravel the interplay between cardiac cells and these proteins/signals to cause stiffness an ....Understanding how an old heart gets stiff. Aging is accompanied by a stiffening of the heart and reduced function, which is accelerated by cardiovascular disease and leads to heart failure. How the heart stiffens is poorly understood. A new mechanism is proposed here, involving structural membrane proteins (termed caveolae and cavins) and a signalling molecule (nitric oxide). The current research aims to unravel the interplay between cardiac cells and these proteins/signals to cause stiffness and to determine whether this process governs normal aging of the heart. This work will advance understanding of how heart function is determined and reveal how the human heart changes with normal aging. Read moreRead less

As the average life expectancy in western countries rises there is an increasing incidence of mental health problems. Therapeutic approaches to both Alzhemier's and Parkinson's disease, as well as to brain injury following stroke, rely on a thorough understanding of how the brain develops. This is consistent with the everyday principle that if you want to fix something that is broken, then you need to understand how it is put together in the first place. This project seeks to understand how the normal brain is wired together in the embryo and, in doing so it will expose novel targets for therapy in the aged.Read moreRead less
