Conti MM, Chambers N, Bishop C. A new outlook on cholinergic interneurons in Parkinson's disease and L-DOPA-induced dyskinesia. Neurosci Biobehav Rev 2018; 92:67-82.

Abstract
Traditionally, dopamine (DA) and acetylcholine (ACh) striatal systems were considered antagonistic and imbalances or aberrant signaling between these neurotransmitter systems could be detrimental to basal ganglia activity and pursuant motor function, such as in Parkinson's disease (PD) and L-DOPA-induced dyskinesia (LID). Herein, we discuss the involvement of cholinergic interneurons (ChIs) in striatally-mediated movement in a healthy, parkinsonian, and dyskinetic state. ChIs integrate numerous neurotransmitter signals using intrinsic glutamate, serotonin, and DA receptors and convey the appropriate transmission onto nearby muscarinic and nicotinic ACh receptors to produce movement. In PD, severe DA depletion causes abnormal rises in ChI activity which promote striatal signaling to attenuate normal movement. When treating PD with L-DOPA, hyperkinetic side effects, or LID, develop due to increased striatal DA; however, the role of ChIs and ACh transmission, until recently has been unclear. Fortunately, new technology and pharmacological agents have facilitated understanding of ChI function and ACh signaling in the context of LID, thus offering new opportunities to modify existing and discover future therapeutic strategies in movement disorders.

Abstract
Involuntary movements, or dyskinesia, represent a debilitating complication of levodopa (L-dopa) therapy for Parkinson's disease (PD). L-dopa-induced dyskinesia (LID) are ultimately experienced by the vast majority of patients. In addition, psychiatric conditions often manifested as compulsive behaviours, are emerging as a serious problem in the management of L-dopa therapy. The present review attempts to provide an overview of our current understanding of dyskinesia and other L-dopa-induced dysfunctions, a field that dramatically evolved in the past twenty years. In view of the extensive literature on LID, there appeared a critical need to re-frame the concepts, to highlight the most suitable models, to review the central nervous system (CNS) circuitry that may be involved, and to propose a pathophysiological framework was timely and necessary. An updated review to clarify our understanding of LID and other L-dopa-related side effects was therefore timely and necessary. This review should help in the development of novel therapeutic strategies aimed at preventing the generation of dyskinetic symptoms.

Abstract
Nicotinic acetylcholine receptors (AChRs) are ACh-gated ion channels formed from five homologous subunits in subtypes defined by their subunit composition and stoichiometry. Some subtypes readily produce functional AChRs in Xenopus oocytes and transfected cell lines. α6β2β3* AChRs (subtypes formed from these subunits and perhaps others) are not easily expressed. This may be because the types of neurons in which they are expressed (typically dopaminergic neurons) have unique chaperones for assembling α6β2β3* AChRs, especially in the presence of the other AChR subtypes. Because these relatively minor brain AChR subtypes are of major importance in addiction to nicotine, it is important for drug development as well as investigation of their functional properties to be able to efficiently express human α6β2β3* AChRs. We review the issues and progress in expressing α6* AChRs. This article is part of the Special Issue entitled 'The Nicotinic Acetylcholine Receptor: From Molecular Biology to Cognition'.

Abstract
We investigated in vivo brain nicotinic acetylcholine receptor (nAChR) distribution in cognitively intact subjects with Parkinson’s disease (PD) at an early stage of the disease. Fourteen patients and 13 healthy subjects were imaged with single photon emission computed tomography and the radiotracer 5-[123I]iodo-3-[2(S)-2-azetidinylmethoxy]pyridine ([123I]5IA). Patients were selected according to several criteria, including short duration of motor signs (<7 years) and normal scores at an extensive neuropsychological evaluation. In PD patients, nAChR density was significantly higher in the putamen, the insular cortex and the supplementary motor area and lower in the caudate nucleus, the orbitofrontal cortex, and the middle temporal gyrus. Disease duration positively correlated with nAChR density in the putamen ipsilateral (ρ = 0.56, p < 0.05) but not contralateral (ρ = 0.49, p = 0.07) to the clinically most affected hemibody. We observed, for the first time in vivo, higher nAChR density in brain regions of the motor and limbic basal ganglia circuits of subjects with PD. Our findings support the notion of an up-regulated cholinergic activity at the striatal and possibly cortical level in cognitively intact PD patients at an early stage of disease.

Abstract
A large body of evidence using experimental animal models shows that the nicotinic cholinergic system is involved in the control of movement under physiological conditions. This work raised the question whether dysregulation of this system may contribute to motor dysfunction and whether drugs targeting nicotinic acetylcholine receptors (nAChRs) may be of therapeutic benefit in movement disorders. Accumulating preclinical studies now show that drugs acting at nAChRs improve drug-induced dyskinesias. The general nAChR agonist nicotine, as well as several nAChR agonists (varenicline, ABT-089 and ABT-894), reduces l-dopa-induced abnormal involuntary movements or dyskinesias up to 60% in parkinsonian nonhuman primates and rodents. These dyskinesias are potentially debilitating abnormal involuntary movements that arise as a complication of l-dopa therapy for Parkinson's disease. In addition, nicotine and varenicline decrease antipsychotic-induced abnormal involuntary movements in rodent models of tardive dyskinesia. Antipsychotic-induced dyskinesias frequently arise as a side effect of chronic drug treatment for schizophrenia, psychosis and other psychiatric disorders. Preclinical and clinical studies also show that the nAChR agonist varenicline improves balance and coordination in various ataxias. Lastly, nicotine has been reported to attenuate the dyskinetic symptoms of Tourette's disorder. Several nAChR subtypes appear to be involved in these beneficial effects of nicotine and nAChR drugs including α4β2*, α6β2* and α7 nAChRs (the asterisk indicates the possible presence of other subunits in the receptor). Overall, the above findings, coupled with nicotine's neuroprotective effects, suggest that nAChR drugs have potential for future drug development for movement disorders.

Abstract
Paraquat, an herbicide widely used in the agricultural industry, has been associated with lung, liver, and kidney toxicity in humans. In addition, it is linked to an increased risk of Parkinson's disease. For this reason, we had previously investigated the effects of paraquat in mice and showed that it influenced striatal nicotinic receptor (nAChR) expression but not nAChR-mediated dopaminergic function. Because nonhuman primates are evolutionarily closer to humans and may better model the effects of pesticide exposure in man, we examined the effects of paraquat on striatal nAChR function and expression in monkeys. Monkeys were administered saline or paraquat once weekly for 6 weeks, after which nAChR levels and receptor-evoked [(3)H]dopamine ([(3)H]DA) release were measured in the striatum. The functional studies showed that paraquat exposure attenuated dopamine (DA) release evoked by alpha3/alpha6beta2(*) (nAChR that is composed of the alpha3 or alpha6 subunits, and beta2; the asterisk indicates the possible presence of additional subunits) nAChRs, a subtype present only on striatal dopaminergic terminals, with no decline in release mediated by alpha4beta2(*) (nAChR containing alpha4 and beta2 subunits, but not alpha3 or alpha6) nAChRs, present on both DA terminals and striatal neurons. Paraquat treatment decreased alpha4beta2(*) but not alpha3/alpha6beta2(*) nAChR expression. The differential effects of paraquat on nAChR expression and receptor-evoked [(3)H]DA release emphasize the importance of evaluating changes in functional measures. The finding that paraquat treatment has a negative impact on striatal nAChR-mediated dopaminergic activity in monkeys but not mice indicates the need for determining the effects of pesticides in higher species.

Abstract
Nicotine treatment has long been associated with alterations in alpha4beta2(*) nicotinic acetylcholine receptor (nAChR) expression that modify dopaminergic function. However, the influence of long-term nicotine treatment on the alpha6beta2(*) nAChR, a subtype specifically localized on dopaminergic neurons, is less clear. Here we used voltammetry, as well as receptor binding studies, to identify the effects of nicotine on striatal alpha6beta2(*) nAChR function and expression. Long-term nicotine treatment via drinking water enhanced nonburst and burst endogenous dopamine release from rat striatal slices. In control animals, alpha6beta2(*) nAChR blockade with alpha-conotoxin MII (alpha-CtxMII) decreased release with nonburst stimulation but not with burst firing. These data in control animals suggest that varying stimulus frequencies differentially regulate alpha6beta2(*) nAChR-evoked dopamine release. In contrast, in nicotine-treated rats, alpha6beta2(*) nAChR blockade elicited a similar pattern of dopamine release with nonburst and burst firing. To elucidate the alpha6beta2(*) nAChR subtypes altered with long-term nicotine treatment, we used the novel alpha-CtxMII analog E11A in combination with alpha4 nAChR knockout mice. (125)I-alpha-CtxMII competition studies in striatum of knockout mice showed that nicotine treatment decreased the alpha6alpha4beta2(*) subtype but increased the alpha6(nonalpha4)beta2(*) nAChR population. These data indicate that alpha6beta2(*) nAChR-evoked dopamine release in nicotine-treated rats is mediated by the alpha6(nonalpha4)beta2(*) nAChR subtype and suggest that the alpha6alpha4beta2(*) nAChR and/or alpha4beta2(*) nAChR contribute to the differential effect of higher frequency stimulation on dopamine release under control conditions. Thus, alpha6beta2(*) nAChR subtypes may represent important targets for smoking cessation therapies and neurological disorders involving these receptors such as Parkinson's disease.

Abstract
Parkinson's disease is a debilitating neurodegenerative movement disorder characterized by damage to the nigrostriatal dopaminergic system. Current therapies are symptomatic only and may be accompanied by serious side effects. There is therefore a continual search for novel compounds for the treatment of Parkinson's disease symptoms, as well as to reduce or halt disease progression. Nicotine administration has been reported to improve motor deficits that arise with nigrostriatal damage in parkinsonian animals and in Parkinson's disease. In addition, nicotine protects against nigrostriatal damage in experimental models, findings that have led to the suggestion that the reduced incidence of Parkinson's disease in smokers may be due to the nicotine in tobacco. Altogether, these observations suggest that nicotine treatment may be beneficial in Parkinson's disease. Nicotine interacts with multiple nicotinic receptor (nAChR) subtypes in the peripheral and central nervous system, as well as in skeletal muscle. Work to identify the subtypes affected in Parkinson's disease is therefore critical for the development of targeted therapies. Results show that striatal alpha6beta2-containing nAChRs are particularly susceptible to nigrostriatal damage, with a decline in receptor levels that closely parallels losses in striatal dopamine. In contrast, alpha4beta2-containing nAChRs are decreased to a much smaller extent under the same conditions. These observations suggest that development of nAChR agonists or antagonists targeted to alpha6beta2-containing nAChRs may represent a particularly relevant target for Parkinson's disease therapeutics.

Abstract
We quantified in vivo brain nicotinic acetylcholine receptor (nAChR) distributions in patients with Parkinson's disease (PD) and evaluated correlations between nAChR distributions and clinical variables of the patients, especially dopaminergic medications. Ten patients with PD without dementia underwent 5-(123)I-iodo-3-(2(S)-azetidinylmethoxy)pyridine ((123)I-5IA) single photon emission computed tomography (SPECT) and the data were compared with those of 10 age-matched healthy volunteers. Correlation analyses between (123)I-5IA distribution volumes (DVs) in each brain region and clinical variables of the patients were also performed. The PD group showed a statistically significant decrease (20-25%) in the brainstem and frontal cortex as compared with the control group. Although age, duration of disease, daily dose of levodopa, duration of PD medication use, and scores on the motor section of Unified Parkinson's Disease Rating Scale were not significantly correlated with DV values in any brain regions, high daily doses of dopamine agonist showed a significant negative correlation with DVs in the cerebellum, and temporal, parietal and occipital cortices. These findings suggest that patients with PD without dementia can show reductions especially in the brainstem and frontal cortex. They also suggest that dopamine agonists can have a negative influence on the distribution of nAChRs.

Abstract
Recent studies in nonhuman primates show that chronic nicotine treatment protects against nigrostriatal degeneration, with a partial restoration of neurochemical and functional measures in the striatum. The present studies were done to determine whether long-term nicotine treatment also protected against striatal nicotinic receptor (nAChR) losses after nigrostriatal damage. Monkeys were administered nicotine in the drinking water for 6 months and subsequently lesioned with the dopaminergic neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) over several months while nicotine was continued. (125)I-Epibatidine, [(125)I]5-[(125)I]iodo-3(2(S)-azetidinylmethoxy)-pyridine (A85380), and (125)I-alpha-conotoxinMII autoradiography was performed to evaluate changes in alpha4beta2* and alpha3/alpha6beta2* nAChRs, the major striatal subtypes. Nicotine treatment increased alpha4beta2* nAChRs by > or =50% in striatum of both unlesioned and lesioned animals. This increase in alpha4beta2* nAChRs was significantly greater in lesioned compared with unlesioned monkey striatum. Chronic nicotine treatment led to a small decrease in alpha3/alpha6beta2* nAChR subtypes. The decline in alpha3/alpha6beta2* subtypes, defined using alpha-conotoxinMII-sensitive (125)I-epibatidine or [(125)I]A85380 binding, was significantly smaller in striatum of nicotine-treated lesioned monkeys compared with unlesioned monkeys. This difference was not observed for alpha3/alpha6beta2* nAChRs identified using (125)I-alpha-conotoxinMII. These data suggest that there are at least two striatal alpha3/alpha6beta2* subtypes that are differentially affected by chronic nicotine treatment in lesioned animals. In addition, the results showing an improvement in striatal alpha4beta2* and select alpha3/alpha6beta2* nAChR subtypes, combined with previous work, demonstrate that chronic nicotine treatment restores and/or protects against the loss of multiple molecular markers after nigrostriatal damage. Such findings suggest that nicotine or nicotinic agonists may be of therapeutic value in Parkinson's disease.

Abstract
OBJECTIVE Nicotinic acetylcholine receptors have close interactions with the dopaminergic system and play critical roles in cognitive function. The purpose of this study was to compare these receptors between living PD patients and healthy subjects. METHODS Nicotinic acetylcholine receptors were imaged in 10 nondemented Parkinson's disease patients and 15 age-matched healthy subjects using a single-photon emission computed tomography ligand [(123)I]5-iodo-3-[2(S)-2-azetidinylmethoxy]pyridine. Using an arterial input function, we measured the total distribution volume (V; specific plus nondisplaceable), as well as the delivery (K(1)). RESULTS Parkinson's disease showed a widespread significant decrease (approximately 10%) of V in both cortical and subcortical regions without a significant change in K(1). INTERPRETATION These results indicate the importance of extending the study to demented patients.

Abstract
Nicotinic acetylcholine receptors mediate the parasympathetic autonomic control of cardiac function. Aim of this study was the assessment of cardiac nicotinic acetylcholine receptor distribution with a novel (alpha4beta2) nicotinic acetylcholine receptor PET ligand (2-deoxy-2- [18F]fluoro-D-glucose-A85380) in humans. Five healthy volunteers without cardiac disease and six patients with either Parkinson's disease or multiple system atrophy without additional overt cardiac disease were evaluated with 2-deoxy-2-[18F]fluoro-D-glucose-A85380 PET-imaging to assess the cardiac parasympathetic innervation and the putative impact of both disorders. 2-deoxy-2- [18F]fluoro-D-glucose-A85380 whole body PET-scans were performed on a Siemens PET/CT biograph(TM) 75.4 min +/- 6.7 after i.v. injection of 371.2 +/- 58.1 MBq. Average count rate density of left ventricle ROI's and a standard ROI in the right lung were measured within three consecutive slices of 10.0 mm thickness. Heart-to-lung ratios were calculated in each volunteer and patient. Tracer uptake in the left ventricle could be measured in all of the five volunteers and the six patients. Heart-to-lung ratios in the volunteer group were not different from patients suffering from Parkinson's disease or MSA (3.2 +/- 0.5 vs 3.2 +/- 0.8 and 2.96+/-0.7, mean +/- SD), respectively. Human cardiac nicotinic acetylcholine receptors can be visualized and measured by 2-deoxy-2- [18F]fluoro-D-glucose-A85380 PET scans both in cardiac-healthy subjects and patients suffering from Parkinson's disease or multiple system atrophy. The heart- as well as the lung-tracer uptake was almost constant throughout all subjects leading to a good target-to-background ratio. These first results suggest no impact of either PD or MSA on cardiac nicotinic acetylcholine receptors.

Abstract
Homeostatic interactions between dopamine and glutamate are central to the normal physiology of the basal ganglia. This relationship is altered in Parkinsonism and in levodopa-induced dyskinesias (LID), resulting in an upregulation of corticostriatal glutamatergic function. Kynurenic acid (KYNA), a tryptophan metabolite with antagonist activity at ionotropic glutamate receptors and the capability to inhibit glutamate release presynaptically, might therefore be of therapeutic value in LID. To evaluate this hypothesis, we used a pharmacological tool, the kynurenine 3-hydroxylase inhibitor Ro 61-8048, which raises KYNA levels acutely. Ro 61-8048 was tested in MPTP cynomolgus monkeys with a stable parkinsonian syndrome and reproducible dyskinesias after each dose of levodopa. Serum and CSF concentrations of KYNA and its precursor kynurenine increased dose-dependently after Ro 61-8048 administration, alone or in combination with levodopa. Coadministration of Ro 61-8048 with levodopa produced a moderate but significant reduction in the severity of dyskinesias while maintaining the motor benefit. These results suggest that elevation of KYNA levels through inhibition of kynurenine 3-hydroxylase constitutes a promising novel approach for managing LID in Parkinson's disease.

Abstract
Nicotinic acetylcholine receptors (nAChRs) represent an important modulator of striatal function both under normal conditions and in pathological states such as Parkinson's disease. Because different nAChR subtypes may have unique functions, immunoprecipitation and ligand binding studies were done to identify their subunit composition. As in the rodent, alpha2, alpha4, alpha6, beta2, and beta3 nAChR subunit immunoreactivity was identified in monkey striatum. However, distinct from the rodent, the present results also revealed the novel presence of alpha3 nAChR subunit-immunoreactivity in this same region, but not that for alpha5 and beta4. Relatively high levels of alpha2 and alpha3 subunits were also identified in monkey cortex, in addition to alpha4 and beta2. Experiments were next done to determine whether striatal subunit expression was changed with nigrostriatal damage. 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine treatment decreased alpha6 and beta3 subunit immunoreactivity by approximately 80% in parallel with the dopamine transporter, suggesting that they are predominantly expressed on nigrostriatal dopaminergic projections. In contrast, alpha3, alpha4, and beta2 subunit immunoreactivity was decreased approximately 50%, whereas alpha2 was not changed. These data, together with those from dual immunoprecipitation and radioligand binding studies ([(3)H]cytisine, (125)I-alpha-bungarotoxin, and (125)I-alpha-conotoxin MII) suggest the following: that alpha6beta2beta3, alpha6alpha4beta2beta3, and alpha3beta2* nAChR subtypes are present on dopaminergic terminals and that the alpha4beta2 subtype is localized on both dopaminergic and nondopaminergic neurons, whereas alpha2beta2* and alpha7 receptors are localized on nondopaminergic cells in monkey striatum. Overall, these results suggest that drugs targeting non-alpha7 nicotinic receptors may be useful in the treatment of disorders characterized by nigrostriatal dopaminergic damage, such as Parkinson's disease.

Abstract
Multiple nicotinic receptors are present in rodent and monkey striatum, with a selective localization of alpha-conotoxinMII-sensitive sites in the striatum and preferential declines in their numbers after nigrostriatal damage. Here we report the presence of 125I-alpha-conotoxinMII and alpha-conotoxinMII-sensitive 125I-epibatidine nicotinic receptors in human control and Parkinson's disease striatum. 125I-alpha-ConotoxinMII bound to control striatum with the characteristics of a nicotinic receptor ligand although the number of sites was approximately fivefold lower than in rodent and monkey. Competition analyses of alpha-conotoxinMII with 125I-epibatidine showed that toxin-sensitive sites comprised approximately 15% of nicotinic receptors in human striatum. In Parkinson's disease caudate, there was a approximately 50% decline in 125I-alpha-conotoxinMII sites with a similar decline in the dopamine transporter. In putamen, there were substantially greater losses of the dopamine transporter (80-90%) but only 50-60% decreases in 125I-alpha-conotoxinMII sites with corresponding declines in alpha-conotoxinMII-sensitive 125I-epibatidine sites, 125I-epibatidine (multiple) sites and 125I-A85380 (beta2-containing) nicotinic receptors. The greater loss of the transporter compared with nicotinic sites suggests that only a subpopulation of nicotinic receptors is located pre-synaptically on striatal dopaminergic neurons in man. Correlation analyses between changes in nicotinic receptors and the dopamine transporter in Parkinson's disease striatum suggest that alpha-conotoxinMII-sensitive 125I-epibatidine sites (low-affinity sites), 125I-A85380 and 125I-epibatidine sites are localized in part to dopaminergic terminals. In summary, these results show that alpha-conotoxinMII-sensitive sites are present in human striatum and that there are high- and low-affinity subtypes which are both decreased in Parkinson's disease.
