Motor behavior is modulated by dopamine-responsive neurons in the striatum, where dopaminergic signaling uses G-protein-coupled pathways, including those that result in the activation of cAMP-dependent protein kinase (PKA). The RIIbeta isoform of PKA is highly enriched in the striatum, and targeted disruption of the RIIbeta gene in mice leads to a dramatic reduction in total PKA activity in thi...
OBJECTIVES This paper gives an overview of studies on the association between dopaminergic neurotransmission and the subjective experience of patients with schizophrenia. METHODS We undertook a review of the literature. RESULTS Dopaminergic neurotransmission may be relevant for subjective experience. Higher striatal D2 receptor occupancy by typical and atypical antipsychotics is related to ...
Repeated exposures to stress sensitize motor and addictive effects of drugs of abuse. Recently, it has been shown that stress-induced behavioral sensitization depends on the secretion of glucocorticoids. We investigated if sensitization of dopamine-dependent effects of psychostimulants and opioids was influenced by glucocorticoid. Sensitization of the dopaminergic response to drugs is considere...
Parkinson’s disease (PD) is a progressive neurodegenerative that characterized by the loss of dopamine. Since dopamine has trouble entering blood–brain barrier, utilization dendrimers and other nanomaterials considered for conjugating neurotransmitter PD drugs. Dendrimers are three-dimensional, hyper-branched structures categorized into several generations. Alpha-synuclein (ASN) protein involve...
We have been investigating the role that phosphatidylethanolamine (PE) and phosphatidylcholine (PC) content plays in modulating the solubility of the Parkinson's disease protein alpha-synuclein (α-syn) using Saccharomyces cerevisiae and Caenorhabditis elegans. One enzyme that synthesizes PE is the conserved enzyme phosphatidylserine decarboxylase (Psd1/yeast; PSD-1/worms), which is lodged in th...
Parkinson's disease is characterized by a triad of cardinal motor symptoms (bradykinesia, rigidity and tremor) resulting from the loss of dopaminergic neurons in the substantia nigra. This synucleinopathy is classified in the larger group of Lewy body disorders. Currently, these symptoms are relatively well alleviated by drugs that restore dopaminergic neurotransmission, andlor by deep brain st...
Dopaminergic neurons exert a major modulatory effect on the forebrain. Dopamine and adenosine 3',5'-monophosphate-regulated phosphoprotein (32 kilodaltons) (DARPP-32), which is enriched in all neurons that receive a dopaminergic input, is converted in response to dopamine into a potent protein phosphatase inhibitor. Mice generated to contain a targeted disruption of the DARPP-32 gene showed pro...
Dopaminergic drugs can cause augmentation during the treatment of restless legs syndrome (RLS). We previously reported that sudden withdrawal of dopaminergic treatment was poorly tolerated. We now report our experience with gradual withdrawal of the dopaminergic drug during the drug substitution process using a retrospective chart review with comparison to previous data. Seven patients with RLS...
