l-Dopa and Brain Serotonin System Dysfunction
L-dopa is used to treat the motor symptoms associated with Parkinson's disease, a neurodegenerative movement disorder characterized by a loss of dopamine neurons. L-dopa is the precursor to dopamine and crosses the blood-brain barrier to increase dopamine neurotransmission. This review will focus on the findings that dopamine produced from L-dopa is mediated in part by serotonin neurons. Direct...
متن کاملEffects of L-dopa on norepinephrine metabolism in the brain.
Rats received intracisternal [(3)H]norepinephrine and, after 5 min, intraperitoneal L-dopa (100 mg/kg); they were killed at intervals during the subsequent 24 hr. Their brains were assayed for norepinephrine, L-dopa, S-adenosylmethionine, and [(3)H]norepinephrine and its metabolites. Rats that received L-dopa had markedly lower brain concentrations of S-adenosylmethionine and of O-methylated me...
متن کاملEffects of L - Dopa on Norepiilephrine Metabolism in the Brain
Rats received intracisternal 1aIlnorepinephrine and, after 5 min, intraperitoneal L-dopa (100 mg/kg); they were killed at intervals during the subsequent 24 hr. Their brains were assayed for norepinephrile, L-dopa, S-adenosylmethionine, and [aH]norepilnephrine and its metabolites. Rats that received L-dopa had markedly lower brain concentrations of S-adenosylnethionine and of O-methylated metab...
متن کاملInvolvement of the serotonin system in L-dopa-induced dyskinesias.
The ability of L-dopa to relieve the motor impairments in Parkinson's disease patients declines over time, and side-effects, such as dyskinesias, appear--limiting the use of the drug in the advanced stage of the disease. Serotonergic neurons are able to convert L-dopa to dopamine and to store this neurotransmitter in synaptic vesicles. This peculiarity might be very important in the advanced di...

Oleh Hornykiewicz was born in 1926 in Sykhiw, Poland (now Ukraine). In 1951, he received his M.D. degree from the University of Vienna and joined the faculty of his alma mater the same year and has worked there ever since. He also served for twenty years as chairman of the Institute of Biochemical Pharmacology. In 1967, he began a long association with the University of Toronto in Canada and, i...
