Exploring the impact of nanoparticle design on Parkinson's disease therapies

NanoWerk.com - 2 hours 9 min ago
Alpha-synuclein is a protein whose function in the healthy brain is currently unknown. It is of great interest to Parkinson's researchers because it is a major constituent of Lewy bodies, protein clumps that are the pathological hallmark of Parkinson's disease (PD). Scientists believe that the self-assembly of alpha-synuclein into oligomers and fibrils is linked to progress and pathogenesis of the disease. A new study suggest that important characteristics of the fibrillation process, such as surface charge and surface functional group, should be considered in the development of nanotechnology-based therapeutic approaches.
