Parkinson disease (PD) is a debilitating and lethal neurodegenerative disease, for which there is currently no cure. It is caused by the progressive loss of nerve cells that produce the chemical dopamine and is characterized by the accumulation of abnormal aggregates of a protein called alpha-syn in these dopaminergic nerve cells. Several previous studies have suggested that the alpha-syn aggregates contribute to PD pathology, so it is possible that an agent that inhibits and/or, better yet, reverses alpha-syn aggregation could be eventually used as a therapy for PD. Evidence to suggest that agents that disrupt alpha-syn aggregation might have beneficial effects in individuals with PD has now been provided by a team of researchers, at the Ecole Polytechnique Fédérale de Lausanne, Switzerland, and the University of Pennsylvania School of Medicine, Philadelphia, who studied a rat model of the disease.

The current issue of CELL TRANSPLANTATION (Vol. 17:4) features a number of publications by researchers seeking new ways to treat Parkinson’s disease (PD), a neurological disease characterized by muscle rigidity, tremor and slowed physical movements related to insufficient levels of dopamine (DA) in the basal ganglia of the brain, by using primate models to examine the potential therapy role of transplanted cells.

A new blood test that can give an early diagnosis of neurodegenerative disease and distinguish between Parkinson’s and Alzheimer’s disease could be launched this summer, reports Marina Murphy in SCI’s Chemistry & Industry magazine.

In 2006, University of North Carolina at Chapel Hill researchers published a study that found people with low levels of LDL cholesterol are more likely to have Parkinson’s disease than people with high LDL levels.

Gene linked to development of the disease in those with a family history

Researchers at Rhode Island Hospital and The Warren Alpert Medical School of Brown University have discovered a gene that could hold the key to developing new treatments for Parkinson’s disease – a progressive and often debilitating movement disorder that affects as many as one million Americans.

Research led by investigators at Memorial Sloan-Kettering Cancer Center (MSKCC) has shown that therapeutic cloning, also known as somatic-cell nuclear transfer (SCNT), can be used to treat Parkinson’s disease in mice. The study’s results are published in the March 23 online edition of the journal Nature Medicine.

New ways to grow brain cells in the laboratory could eventually provide a way to treat Parkinson’s disease
Scientists in Sweden are developing new ways to grow brain cells in the laboratory that could one day be used to treat patients with Parkinson’s disease, an international conference of biologists organised by the European Science Foundation (ESF) was told last week.

A brain chemical that makes us sleepy also appears to play a central role in the success of deep brain stimulation to ease symptoms in patients with Parkinson’s disease and other brain disorders. The surprising finding is outlined in a paper published online Dec. 23 in Nature Medicine.
