Scarlet protein has a protective effect against Parkinson’s disease in fruit flies.
Researchers at the Department of Biological Sciences at Lehigh University in Bethlehem, Pennsylvania, discovered that a protein known as Scarlet has protective effects against the fruit fly version of Parkinson’s disease [1].
Abstract
Parkinson’s Disease (PD) is characterized by the loss of dopaminergic neurons, resulting in progressive locomotor dysfunction. Identification of genes required for the maintenance of these neurons should help to identify potential therapeutic targets. However, little is known regarding the factors that render dopaminergic neurons selectively vulnerable to PD. Here we show that Drosophila melanogaster scarlet mutants exhibit an age-dependent progressive loss of dopaminergic neurons, along with subsequent locomotor defects and a shortened lifespan. Knockdown of Scarlet specifically within dopaminergic neurons is sufficient to produce this neurodegeneration, demonstrating a unique role for Scarlet beyond its well-characterized role in eye pigmentation.
