Steroid discovered in dogfish sharks attacks Parkinson's-related toxin in animal model

A synthesized steroid mirroring one naturally made by the dogfish shark prevents the buildup of a lethal protein implicated in some neurodegenerative diseases, reports an international research team studying an animal model of Parkinson's disease. The clustering of this protein, alpha-synuclein, is the hallmark of Parkinson's and dementia with Lewy bodies, suggesting a new potential compound for therapeutic research.
