Protein protects against degeneration of neurons in fruit flies

of neurons similar to those affected in Parkinsons disease. The protective protein, called a chaperone, suppresses the toxicity of a -synuclein, a protein associated with Parkinsons disease in humans. Progressive loss of dopaminergic neurons produce...
