Summary
Multiple sclerosis (MS) is a common neurological disease which affects about 10,000 people in Australia. In MS, a persons own immune system starts to attack specific parts of their brain and spinal cord, causing lesions that prevent nerve impulses from passing from the brain to other parts of the body. The symptoms that people with MS develop can vary from one person to another, depending on where in the brain or spinal cord the lesions occur. Some parts of the brain and spinal cord seem to be m ....Multiple sclerosis (MS) is a common neurological disease which affects about 10,000 people in Australia. In MS, a persons own immune system starts to attack specific parts of their brain and spinal cord, causing lesions that prevent nerve impulses from passing from the brain to other parts of the body. The symptoms that people with MS develop can vary from one person to another, depending on where in the brain or spinal cord the lesions occur. Some parts of the brain and spinal cord seem to be much more susceptible to this attack than others, and the question that this study will address is why do lesions occur where they do in MS? Some preliminary results strongly suggest that there is a link between carrying particular genes that control immune responses, having immune cells that can attack one particular protein in the nervous system called PLP, and developing lesions in parts of the brain that control balance. This will be investigated further, and we will also look for other links between immune cells that can attack other proteins and development of lesions in particular areas. If such links can be identified, they would be very important for improved diagnosis of MS and it would enable more specific treatments for MS to be developed. We will also use experimental models of MS to investigate the exact components within the nervous system and within the immune system that play a role in directing the attack to particular sites.Read moreRead less

Summary
Breast screening has been successful in reducing deaths from breast cancer. Unfortunately it also detects increasing numbers of precancerous changes. Treatment of these changes is often aggressive, using surgery and radiotherapy. However we are unable to predict exactly which of the changes we need to treat. We aim to better understand the changes involved in this progression and try to block them using new drugs.
The brain exerts a restraining influence over the heartbeat via the vagus nerves. This is known as cardiac vagal ‘tone’. It is strong when we are healthy but weak when we are sick. It has a positive influence on the health of the heart and perhaps the body generally. Vagal tone comes from the brain but, despite over 150 years’ research, nobody knows exactly where. Using a novel technique, we can track down its origins. This important basic knowledge may lead to ways to improve health.
