Summary
The CD46 protein enables entry into cells of a number of different pathogens, including the measles virus, Neisseria meningitidis (the major cause of meningococcal disease), Neisseria gonorrhoea, Human Herpes Virus 6, and group A streptococcus. In addition, by binding to a key blood component that is often attached to foreign pathogens, CD46 can facilitate binding and entry of other pathogens. As well as facilitating entry of the pathogen, it has recently become apparent that CD46 binding trigge ....The CD46 protein enables entry into cells of a number of different pathogens, including the measles virus, Neisseria meningitidis (the major cause of meningococcal disease), Neisseria gonorrhoea, Human Herpes Virus 6, and group A streptococcus. In addition, by binding to a key blood component that is often attached to foreign pathogens, CD46 can facilitate binding and entry of other pathogens. As well as facilitating entry of the pathogen, it has recently become apparent that CD46 binding triggers a wide range of responses from the human host. Some of these responses are likely to further facilitate survival and proliferation of the pathogen, but others are more likely to facilitate host defence. For examples, signals triggered by binding to CD46 can both abrogate some aspects of the immune response (and it is though that this immunosuppression contributes to the secondary infections that cause the death of nearly one million children each year) and facilitate other aspects of the immune response. By understanding the mechanisms by which CD46 triggers these complex responses, we firstly be able to dissect how important each of these processes are to the overall pathogenecity of the virus or bacteria. Furthmore, this understanding will allow us to design better vaccines and drugs to combat these diseases.Read moreRead less

Summary
The body stores energy acquired from ingested food as fat droplets within storage cells termed adipocytes. The amount of fat varies between individuals and may also vary during an individual's life. The variations reflect differences in physiology, diet, and behaviour and have been the focus of intense study. Excessive accumulation of fat is a serious health problem as it is associated with conditions such as heart disease and diabetes. This grant application primarily concerns using a new line ....The body stores energy acquired from ingested food as fat droplets within storage cells termed adipocytes. The amount of fat varies between individuals and may also vary during an individual's life. The variations reflect differences in physiology, diet, and behaviour and have been the focus of intense study. Excessive accumulation of fat is a serious health problem as it is associated with conditions such as heart disease and diabetes. This grant application primarily concerns using a new line of genetically modified mice that have reduced fat. These mice lack a key gene regulatory protein that is implicated in fat accummulation and adipocyte formation. It is expected that a knowledge of the genes regulating the formation and function of fat storage cells will contribute to new strategies for controlling fat formation and will help in the prevention of diseases such as diabetes and heart disease.Read moreRead less
