They might not be known for their big brains, but fruit flies are helping to make scientists and doctors smarter about what causes Huntington’s disease and how to treat it. New research, published in the journal GENETICS describes a laboratory test that allows scientists to evaluate large numbers of fruit fly genes for a possible role in the formation of plaque-like protein aggregates within cells. Those genes often have counterparts in humans, which might then be manipulated to stop or slow the formation of plaque-like protein aggregates, the hallmark of Huntington’s and several other neurodegenerative diseases.
