Research into Parkinson's disease: Binding-protein prevents fibril proliferation

Protein aggregates have been observed in the nerve tissue of patients with Parkinson's disease which consist of individual components (monomers) of the protein α-synuclein which assemble into what are referred to as amyloid fibrils. Similar deposits are also found in the case of other neurodegenerative diseases such as Alzheimer's. Researchers are looking for approaches to prevent fibril formation and potentially cure the diseases.

Securing enough energy to meet human needs is one of the greatest challenges society has ever faced. Previously reliable sources—oil, gas and coal—are degrading air quality, devastating land and ocean and altering the fragile balance of the global climate, through the release of CO2 and other greenhouse gases. Meanwhile, earth's rapidly industrializing population is projected to reach 10 billion by 2050. Clean alternatives are a matter of urgent necessity.
