A Vulnerable Subtype of Dopaminergic Neurons Drives Early Motor Deficits in Parkinson's Disease
This study identifies a selectively vulnerable Anxa1+ subtype of Sox6+ dopaminergic neurons in the ventral substantia nigra as the driver of early motor deficits in Parkinson's disease, establishing Anxa1 as both a biomarker for this vulnerable population and a sufficient cause of symptoms like bradykinesia and tremor.
