New research reveals how alpha-synuclein interacts with cell membranes in Parkinson's disease

The accumulation of α-synuclein, a small, negatively charged protein, in neural cells, is one of the hallmarks of Parkinson's disease. It has been suggested that oligomeric α-synuclein causes membranes to become permeable, or to form channels on the outer cell membrane. Now, a group of scientists from Sweden has found a way to reliably replicate α-synuclein aggregation on cell membranes to investigate how different forms of α-synuclein interact with membranes under different conditions and to learn if any of the α-synuclein species can penetrate these membranes. Their results are published in the current issue of the Journal of Parkinson's Disease.
