Hsp104 antagonizes alpha-synuclein aggregation and reduces dopaminergic degeneration in a rat model of Parkinson disease

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......
