Summary
The innate immune system is a critical barrier against invading microorganisms, however when improperly regulated it can lead to autoimmune disease. Nalp1 is a protein that is important for innate immune recognition of anthrax infection, and is also involved in susceptibility to vitiligo and associated autoimmune diseases. This project seeks to create mice that are deficient for the gene encoding Nalp1 so as to further study the role of this protein in innate immune defense and autoimmunity.
The Role Of Androgens In Osteoblast Development And Bone Metabolism

Summary
Male hormones are essential for the growth and maintenance of bone in men, but exactly how and when they act on the bone forming cells is unclear. We aim to find out what happens when the target for male hormones (receptor) is removed in the bone forming cells at different stages of their development. This project will increase our understanding of how male hormones regulate bone formation and may assist in the design of new therapies for osteoporosis.

Summary
Appetite and food intake is regulated by specific neuronal structures in the brain. The most important area is the hypothalamus from which many neuronal pathways originate to control specific aspects of feeding behaviour and energy usage in the brain and the rest of the body. To better understand the contribution individual neuronal populations make to drive excess food intake we propose a new approach to identify this, making new treatment options for eating disorders and obesity possible.

Summary
Overweight and Obesity are very prevalent in our society. Obesity is the cause of many medical problems including type 2 diabetes, high blood pressure, abnormal lipids, sleep apnoea, arthritis and some cancers. The idea that individuals can freely choose whether they eat or not eat is only true in the short term. Recent work has clearly shown that the desire to eat (hunger) and the decision to stop eating (satiety) are determined by the net level of many chemicals (neurotransmitters) in an area ....Overweight and Obesity are very prevalent in our society. Obesity is the cause of many medical problems including type 2 diabetes, high blood pressure, abnormal lipids, sleep apnoea, arthritis and some cancers. The idea that individuals can freely choose whether they eat or not eat is only true in the short term. Recent work has clearly shown that the desire to eat (hunger) and the decision to stop eating (satiety) are determined by the net level of many chemicals (neurotransmitters) in an area of the brain called the hypothalamus. Malfunction in some of these neurotransmitters has been shown to cause severe obesity in both animals and humans. A clear understanding of how the hypothalamus regulates body weight may lead to treatments for both severe obesity and anorexia. This project deals with investigating the role of a new hypothalamic protein in body weight regulation. This protein called beacon was discovered by one of the chief investigators (GC) who has shown that when it is injected in the brain it causes rats to overeat and put on excess weight. The aim of this project is to produce mice in which the amount of beacon is increased in the brain and other mice who do not have beacon and then to study the impact onthe regulation of body weight.Read moreRead less
