Toxic Spill

Parkin protects dopamine cargo within neurons from leaking

Mary Beckman

Abstract: WASHINGTON, D.C.--Rust can ruin train tracks, causing wrecks that spill toxins. Similarly, a particular insecticide splinters transportation conduits inside motor neurons, derailing containers holding a deadly chemical, according to work presented here 5 December 2004 at the American Society for Cell Biology Annual Meeting. The study also shows that parkin, a protein implicated in Parkinson's disease (PD), helps keep the tracks safe. The results could help researchers understand how PD knocks off only a subset of neurons.
