However, as the primary use of selegiline in PD is as a MAO-B inhibitor, studies performed with Mdmm ESS Performer 2.1 in PD patients are not reviewed in the current paper. Lastly, some compounds discussed here, encompassing amphetamine, its enantiomers, and derivatives such as fenfluramine, act both as monoamine reuptake inhibitors and as monoamine release enhancers references with individual compounds.


These drugs thus have two mechanisms of action which result in Mdmm ESS Performer 2.1 extrasynaptic monoamine levels: Notwithstanding these two mechanisms, these drugs will be considered as monoamine reuptake inhibitors here. Its gene SLC6A3 was first cloned in and is located on chromosome 5 [ 36 — 39 ].

The human DAT gene is a kilobase kb gene that contains 15 exons and Mdmm ESS Performer 2.1 introns [ 40 ] and that codes for a amino acid protein [ 41 ]. Both N- and C-terminals are located intracellularly [ 35 ]. DAT also interacts with other intracellular proteins such as Hic5, protein kinase C PKCprotein phosphatase 2ARack1, synuclein, and syntaxin; these proteins regulate Mdmm ESS Performer 2.1 expression, membrane distribution, and activity [ 35 ]. The orphan nuclear receptor Nurr1 enhances DAT expression [ 45 ]. DAT levels in the striatum of PD patients are markedly reduced [ 1249 — 51 ]. It is localised on chromosome 17, spans about 24 kb, and contains 13 exons. Human brain and platelet SERT is a amino acid protein [ 55 ]. SERT monomers also form oligomers [ 56 ]. The gene is located on chromosome 16, spans 45 kb, contains 14 exons, and codes for a amino acid protein [ 41 ].

Three splice variants have been described, but only two appear to be functional [ 60 ].

NET also interacts with -synuclein [ 61 ]. As mentioned above, there is a degeneration of the noradrenergic system in PD. It showed that [11C]-RTI binding levels were decreased in locus coeruleus LC and anterior cingulate gyrus when depressed PD patients were compared to nondepressed PD patients [ 62 ]. As DAT is expressed only in dopaminergic neurons [ 35 ], the changes encountered in the LC are likely to reflect degeneration of noradrenergic neurons. Dopamine can directly activate serotonergic type 2A [ 65 ], type 1Atype 2Cand type 3 5-HT3 receptors [ 66 ].

In the MPTP-lesioned mouse model of PD, there is a 5-HT hyperinnervation of Mdmm ESS Performer 2.1 striatum, potentially a response to compensate for the loss of afferent dopaminergic fibres [ 67 ]. Mdmm ESS Performer 2.1 findings were encountered in the striatum of the 6-OHDA-lesioned rat model of PD, in both adult-lesioned [ 68 — 70 ] and neonatal-lesioned rats [ 7172 ].

It is believed that this dopamine derived from 5-HT terminals acts as a false neurotransmitter and plays an important role in the emergence of L-DOPA-induced dyskinesia [ 78 — 80 ]. Lastly, noradrenaline can be uptaken by and released from 5-HT terminals [ 88 ]. Thus, by restoring physiological levels of monoamines in the brain, MAUIs could theoretically restore physiological interactions between the monoamines and their transporters, leading to an alleviation of both motor and nonmotor symptoms of PD, as well as to a decrease in treatment-related complications.

Overview SERT inhibitors are widely used as antidepressants. Despite the wide use of antidepressants in PD, concerns remain about their efficacy for depression, safety, and tolerability. Ina Cochrane systematic review concluded that there were insufficient data on the effectiveness against depression and safety of antidepressants in PD to make recommendations [ 93 ] and, ina Mdmm ESS Performer 2.1 and meta-analysis of antidepressants in PD were unable to demonstrate a difference in efficacy between placebo and active treatment [ 94 ]. However, a study in which depressed PD patients were treated with paroxetine, nortriptyline, or placebo found that specific parameters such as somatic anxiety and lack of interest were significantly improved by active treatment [ 96 ].

Moreover, a recent study provided class I evidence that the SSRI paroxetine was effective in treating depression in PD see below [ 9798 ]. Taken together, Mdmm ESS Performer 2.1 data suggest that SSRIs are probably effective against depression and may also effectively alleviate other aspects of PD nonmotor symptomatology, such as anxiety and apathy. One case-series [ 99 ] and one case-report [ ] suggested that the SERT inhibitors citalopram and venlafaxine might also alleviate dopaminergic psychotic features.


One of these potentially life-threatening Mdmm ESS Performer 2.1 events is the 5-HT syndrome, which fortunately occurs fairly rarely when antidepressants are combined with MAO-B inhibitors such as selegiline or rasagiline [ — ]. At present, there is not enough evidence to recommend avoiding the combination of rasagiline and SSRIs, although patients should be informed of the potential interaction between the molecules and of the symptoms of the 5-HT syndrome. The possibility of worsening preexisting Parkinsonism by adding an antidepressant remains controversial, mainly for SSRIs. Thus, a vast pharmacoepidemiologic study found no significant increase in risk of motor deterioration upon antidepressant therapy in PD [ ]. Accordingly, the SSRIs sertraline, paroxetine, and fluoxetine were demonstrated to improve haloperidol-induced catalepsy in mice, suggesting that they may not worsen Parkinsonism in human [ ].

A mechanism by which SERT inhibitors could worsen Parkinsonism may involve 5-HT-mediated activation of receptors within the SN, which leads to a decrease in nigrostriatal dopaminergic transmission [ ]. Alternately, SERT inhibitors might worsen Parkinsonism via a 5-HT-mediated activation of presynaptic receptors [ ], which would result in less dopamine being released from raphe-striatal terminals. If the last mechanism was demonstrated to play a role in the pathophysiology of L-DOPA-induced dyskinesia [ 78 ], its involvement as a determinant of the severity of Parkinsonism or of the efficacy of L-DOPA anti-Parkinsonian action remains hypothetical.

They also exhibit moderate affinity for the alpha 1 adrenoceptors Kd of 1. In Mdmm ESS Performer 2.1, citalopram has high affinity for the histamine H type 1 receptors Kd of 0. Citalopram also has high affinity for the sigma type 1 and moderate affinity for the receptors Kd of 0.


The chemical formulae of citalopram and escitalopram are illustrated in Figure 1. However, the magnitude of REM-sleep reduction was similar in the saline-treated animals [ ]; thus the effect of citalopram on REM-sleep may not be due to an interaction with the disease process. Collectively, these results suggest that both acute and chronic treatment with a SERT inhibitor might reduce dyskinesia severity, while Mdmm ESS Performer 2.1 novo treatment with a SERT inhibitor might attenuate the priming leading to the expression of dyskinesia.

However, a retrospective study conducted in PD patients with a follow-up of at least 10 years found that administration of selective SERT inhibitors does not prevent dyskinesia development, thought it may delay their onset [ ], somewhat contradicting the preclinical rodent data. On another note, in a study presented as an abstract, pretreatment of rats with citalopram and desipramine 30 min prior to 6-OHDA administration in the striatum Mdmm ESS Performer 2.1 contralateral forepaw hyperalgesia [ ].
