Glia and Parkinson's disease

Funded Activity Summary

Parkinson s disease (PD) is a progressively disabling movement disorder afflicting over 25,000 Australians. It is caused by the degeneration of specific nerve cells in the brain that produce certain chemcials and patients suffer from an inability to move fluently (or ultimately at all). At present we do not know what triggers this neurodegeneration. Current symptomatic treatments give sufferers some relief for a period of time by boosting the amount of these depleted chemicals in the brain. However, the underlying cellular degeneration continues unabated until such treatments are no longer effective. It is necessary to determine the reason for the cell loss in the brain in order to develop successful long-term treatments for this disabling disorder. There have been a number of animal models for PD developed. Comparing the type of tissue damage associated with the cell loss in these models shows that signs of brain inflammation occur prior to the loss of nerve cells. This feature consistently occurs regardless of the method used to produce the disease model. However, inflammation has been poorly studied in PD. Part of the present proposal is to analyse the brain tissue from patients with PD in order to document whether inflammation is also a consistent feature in the regions affected by the disease. Other central nervous system disorders in which inflammation is thought to play a pivotal role often have some genetic predisposition to the disorder and there is evidence of an immune response in their blood. We also wish to examine these aspects in patients with PD. Overall, our study will provide the necessary evidence for or against a primary role for inflammation in the disease process causing the ongoing degeneration in PD. If significant indications for a primary role for inflammation are found, treatments specifically targeting inflammation (already available) can be trialled to slow or stop the neurodegeneration.
