Robotic microscope shows mutant Huntington's protein affects neurons

From Eurekalert:

"Using a specially designed robotic microscope to study cultured cells, researchers have found evidence that abnormal protein clumps called inclusion bodies in neurons from people with Huntington's disease (HD) prevent cell death. The finding helps to resolve a longstanding debate about the role of these inclusion bodies in HD and other disorders and may help investigators find effective treatments for these diseases. The study was funded primarily by the NIH's National Institute of Neurological Disorders and Stroke (NINDS) and appears in the October 14, 2004, issue of Nature.*

Inclusion bodies are common to many neurodegenerative disorders, including HD, Parkinson's disease, Alzheimer's disease, and amyotrophic lateral sclerosis (ALS). The role of inclusion bodies in these diseases has long been controversial. Some studies suggest that they may be a critical part of the disease process, while others indicate that they may help protect the cells from toxic proteins or that they are merely bystanders in the disease process.
