Summary
Our recent research suggests that the vertigo attacks associated with enlarged fluid volumes in the inner ear, in diseases such as Ménière's Disease, maybe triggered when the fluid pressure forces open tissue valves located in the fluid-ducts connecting the hearing and balance organs. This project aims to identify the functional role of these valves, and to develop an animal model of abrupt changes in vestibular activity due to hydrops, to allow future treatments to be developed.
Promoting Intestinal Stem-cell Mediated Regeneration Following Damage: A Critical Role For Neuregulin 1

Summary
Diseases, infections and pathologies are common clinical problems of the intestine in humans that can lead to loss of intestinal tissue. Individuals with these conditions can experience nutritional problems and severe cases result in death. Promoting regeneration of the damaged tissue is critical to re-establish intestinal function. In this study, we will examine the regenerative potential of a growth factor called Neuregulin1 in the intestine with the aim of facilitating tissue regeneration.
Targeting Skeletal MTORC1 As A Novel Approach For The Treatment Of Diet-induced Insulin Resistance

Summary
Diet-induced insulin resistance is a pathology that underlies type 2 diabetes. Elucidating the pathways and tissues that contribute to this condition is crucial for drug development. The skeleton has emerged as a critical insulin target tissue. We provide evidence that suppression of mTORC1, a complex over-activated by nutrients, in bone cells improves insulin sensitivity. In this study, we will determine if blocking mTORC1 function in bone cells can treat diet-induced insulin resistance.
A Novel Portable System For Day And Night Closed Loop Automated Insulin Delivery In The Patient With Type 1 Diabetes

Summary
For patients with Type 1 Diabetes, improved glucose control has been shown to reduce the development of diabetes complications. Although advances have been made in therapy, most people with diabetes do not achieve optimal treatment targets and the burden of care is high. Technologies now exist that allow the development of automatic insulin therapy and the artificial pancreas. These experiments will test a novel portable system that represents a significant step advancing toward this goal.
Glycaemia-increasing Effects Of Sprinting In Type 1 Diabetes: Toward The Validation Of New Clinical Guidelines For Hypoglycaemia Prevention

Summary
Recently, we found that the risk of hypoglycaemia associated with moderate intensity exercise in type 1 diabetic individuals is opposed by one or several short sprints performed during or after exercise. Our goal is to examine if exercising several hours before sprinting decreases its protective effect, and whether sprinting may impair several hours later the counterregulatory responses to hypoglycaemia. Finally, we will determine if guidelines advocating the use of short sprints reduce the risk ....Recently, we found that the risk of hypoglycaemia associated with moderate intensity exercise in type 1 diabetic individuals is opposed by one or several short sprints performed during or after exercise. Our goal is to examine if exercising several hours before sprinting decreases its protective effect, and whether sprinting may impair several hours later the counterregulatory responses to hypoglycaemia. Finally, we will determine if guidelines advocating the use of short sprints reduce the risk of hypoglycaemia under free living conditions.Read moreRead less
Obesity is a major global public health concern and there is a desperate need to identify new targets to treat obesity. By targeting the lesser investigated CART pathway and identifying the elusive CART receptor this could make a significant inroad to the understanding of the causes of appetite control and the development of obesity.

Summary
Programmed cell death plays critical roles in development and cell-turnover in the adult. Defects in this process can cause cancer or autoimmune diseases. We will use genetic and biochemical approaches to define the individual roles of necroptosis, a newly described cell death process, and those overlapping with apoptosis in normal development and cell-turnover as well as in cancer and autoimmune diseases. The objective of this work is to identify potential targets for therapeutic intervention i ....Programmed cell death plays critical roles in development and cell-turnover in the adult.

Summary
Small, naturally occurring glycomic molecules control cartilage matrix turnover. We have synthesised small synthetic analogues of the naturally occurring molecules, and demonstrated their ability to regulate signalling pathways. This project will test and mathematical model the synthetic molecules in cell and tissue assays to define their properties and tissue effects, and assess their suitability as a drug delivery system. The results will be an important step towards designing new ways of trea ....Small, naturally occurring glycomic molecules control cartilage matrix turnover.

Summary
We will investigate how the cytokine IL-15 regulates the homeostasis of natural killer (NK) cells. NK cells are critical for immune responses against invading viruses or bacteria or upon detection of transformed cells. NK cells are primed to attack infected or transformed cells and are rapidly activated by direct interaction or by soluble signals. Knowledge of how NK cells development and how their numbers and function are controlled is paramount to understanding infectious disease immunology an ....We will investigate how the cytokine IL-15 regulates the homeostasis of natural killer (NK) cells.

Summary
The brain plays a critical role in body weight gain by balancing appetite-inducing and appetite-suppressing signals. An imbalance in this process causes obesity, promotes diabetes and cardiovascular disease. The aim of this research is to identify how appetite-suppressing brain signals are maintained as a method to prevent obesity progression.
