Biography

Our research focuses on neurodegeneration, particularly as relates to Parkinson’s Disease (PD). Currently we are developing a progressive rat model of PD in which the neurotoxicant, 1-methyl-4-phenylpyridinium (MPP+), is chronically infused into the left cerebral ventricle via a cannula which is connected to an Alzet pump which delivers for 6 weeks. Using this model, we are investigating the role of microglia and other immune cells in mediating damage to the nigrostriatal dopaminergic neurons. Furthermore, we are studying the ability of drugs thought to modulate microglia function for their ability to rescue neurons after the process of neurodegeneration has been initiated
