Summary
This project aims to determine the molecular cause of hereditary motor neuropathies with pyramidal signs by chromosomal linkage studies and to screen suitable families to locate genes with disease causing mutations. We propose to use the resources of the human genome project to locate the defective gene. In previous studies we have used these methods to identify genes of two other hereditary diseases of nerve.

We propose to use the resources of the human genome project to locate the defective gene. In previous studies we have used these methods to identify genes of two other hereditary diseases of nerve. Our data suggests that this disorder forms part of the largest group of hereditary neuropathies yet to be defined. Because this disorder affects long spinal cord neurones, identifying the mutated gene and studying its function may shed light on possible mechanisms involved in other spinal cord diseases. This research is a systematic search and should lead to identifying the abnormal gene causing disease. Once the gene involved is known then an effective diagnostic test will be developed. When a test for the disease is available, it is likely that we will find that the disorder is more common than previously recognised. Knowledge of the function of the gene will lead to an understanding of how the disease develops and will eventually enable development of effective treatments.Read moreRead less

Summary
Bone marrow transplantation (BMT) is the most effect treatment for a number of conditions, especially leukemia. Graft versus host disease (GVHD) is a complication of BMT and results in the death of up to 50% of transplant recipients. GVHD occurs when the newly transplanted immune system recognizes the recipient as foreign and mounts and immune reponse against the patients tissues. These studies will focus on identifying and understanding the function of the immune cells which drive GVHD.

While therapies to treat cancer have continued to improve one area that, in theory at least, shows great promise in the treatment of tumours is manipulating the immune system to effectively recognize and destroy cancerous lesions. Experiments in human and animal systems have clearly shown that the immune system has the potential to respond to tumour cells and trials of tumour vaccines are underway. It has recently become apparent that the immune responses to tumours may be inhibited by classes of regulatory immune cells. Eliminating these cells results in a more vigorous and effective anti-tumour response. This project will seek to discover the mechanisms of action of theses regulatory immune cells in order to devise more effective anti-cancer vaccines and therapies.Read moreRead less
