Abstract:
ATP-sensitive potassium (K(ATP)) channels directly couple the metabolic state of a cell to its electrical activity. Dopaminergic midbrain neurons express alternative types of K(ATP) channels mediating their differential response to mitochondrial complex I inhibition. Because reduced complex I activity is present in Parkinson's Disease, differential K(ATP) channel expression suggests a novel candidate mechanism for selective dopaminergic degeneration.
