Dopaminergic neurons produce dopamine, a neurotransmitter with roles in neurological functions such as mood and reward. Progressive loss of dopaminergic neurons is the cause of many of the motor symptoms associated with Parkinson’s disease.
Tyrosine hydroxylase (TH)
An enzyme that converts L-tyrosine to L-3,4-dihydroxyphelylalanine (L-DOPA), which is a dopamine precursor.
