l-3,4-Dihydroxyphenylalanine induces ptosis through a GPR143-independent mechanism in mice

Journal of Pharmacological Sciences, 2016
Through its conversion to dopamine by aromatic l-amino acid decarboxylase (AADC), l-3,4-dihydroxyphenylalanine (l-DOPA) replenishes depleted brain dopamine in Parkinson's disease patients. We recently identified GPR143 as a candidate receptor for l-DOPA.

Genetic associations of single nucleotide polymorphisms in the l-DOPA receptor (GPR143) gene with severity of nicotine dependence in Japanese individuals, and attenuation of nicotine reinforcement in Gpr143 gene-deficient mice

Journal of Pharmacological Sciences, 2020
l-3,4-dihydroxyphenylalanine (l-DOPA) is a candidate neurotransmitter. l-DOPA is released by nicotine through nicotinic receptors. Recently, G-protein coupled receptor GPR143, was identified as a receptor for l-DOPA.

Effect of Selective Serotonin Reuptake Inhibitors via 5-HT1A Receptors on L-DOPA-Induced Rotational Behavior in a Hemiparkinsonian Rat Model

Journal of Pharmacological Sciences, 2012
l-Dihydroxyphenylalanine (l-DOPA) is considered the gold standard for the treatment of Parkinson’s disease (PD). However, long-term administration of l-DOPA can induce abnormal side effects.
