l-DOPA and Its Receptor GPR143: Implications for Pathogenesis and Therapy in Parkinson’s Disease

Frontiers in Pharmacology, 2019
l-3,4-Dihydroxyphenylalanine (l-DOPA) is the most effective therapeutic agent for Parkinson’s disease (PD). l-DOPA is traditionally believed to be an inert amino acid that exerts actions and effectiveness in PD through its conversion to dopamine.
