Results of autopsy studies suggest that brainstem pathology, including the accumulation of α-synuclein, precedes damage to dopaminergic neurons in the substantia nigra in PD. However, the molecular and cellular mechanisms responsible for the early dysfunction of brainstem autonomic neurons are unknown. Here we report that mice expr ...[more]
