    • Microglia are resident immunosurveillant cells in the central nervous system, and astrocytes are important for blood flow, plasticity, and neurotransmitter regulation. The aim of this study was to investigate whether astrocyte and microglial activation, estimated through markers in cerebrospinal fluid and serum, differed between synucleinopathies, tauopathies, and controls.

  • From iPS Cells to Rodents and Nonhuman Primates : Filling Gaps in Modeling Parkinson's Disease
  • 2021

    • Parkinson's disease (PD) is primarily known as a movement disorder because of typical clinical manifestations associated with the loss of dopaminergic neurons in the substantia nigra. However, it is now widely recognized that PD is a much more complex condition, with multiple and severe nonmotor features implicating additional brain areas and organs in the disease process. Pathologically, typical forms of PD are characterized by the accumulation of α-synuclein-rich protein inclusions known as Lewy bodies and Lewy neurites, although other types of protein inclusions are also often present in the brain. Familial forms of PD have provided a wealth of information about molecular pathways leading to neurodegeneration, but only to add to the complexity of the problem and uncover new knowledge gaps. Therefore, modeling PD in the laboratory has become increasingly challenging. Here, we discuss knowledge gaps and challenges in the use of laboratory models for the study of a disease that is clinically heterogeneous and multifactorial. We propose that the combined use of patient-derived cells and animal models, along with current technological tools, will not only expand our molecular and pathophysiological understanding of PD, but also assist in the identification of therapeutic strategies targeting relevant pathogenic pathways.

  • Levodopa infusion does not decrease the onset of abnormal involuntary movements in parkinsonian rats
  • 2013
  • Ingår i: Movement Disorders. - : Wiley. - 0885-3185 .- 1531-8257. ; 28:8, s. 1072-1079

    • The short duration of effect of levodopa is linked to pulsatile stimulation of striatal dopamine receptors and dyskinesia induction. However, the recent introduction of intraduodenal (i.d.) infusions and novel oral controlled release formulations of l-dopa may prevent dyskinesia induction and reduce the severity of established involuntary movements. We have compared the effects of twice-daily intraperitoneal (i.p.) administration and daily i.d. infusion of l-dopa on the induction and expression of abnormal involuntary movements in 6-hydroxydopamine (6-OHDA)-lesioned rats. Animals were treated with either twice-daily i.p. administration of l-dopa/carbidopa (7.85/12.5 mg/kg) or an 8-hour i.d. infusion of l-dopa/carbidopa (20/5 mg/mL; infusion rate: 0.04 mL/h) for 14 days, after which treatments were switched between groups and continued for a further 14 days. Pulsatile i.p. administration of l-dopa induced moderate to severe abnormal involuntary movements, which gradually increased in severity over the 14 days, but i.d. infusion of l-dopa induced abnormal involuntary movements of a similar severity. Switching from continuous i.d. to pulsatile i.p. administration of l-dopa continued to provoke severe abnormal involuntary movements expression. Switching from pulsatile i.p. to continuous i.d. l-dopa administration did not alter the peak abnormal involuntary movement severity but tended to reduce their duration. Treatment with less pulsatile l-dopa administration using i.d. infusion does not reduce the risk of the appearance of dyskinesia. By contrast, the duration of established dyskinesia can be reduced by more continuous l-dopa delivery in agreement with clinical experience

  • Neuronal intranuclear inclusion disease : Report on a case originally diagnosed as dopa-responsive dystonia with lewy bodies
  • 2005
  • Ingår i: Movement Disorders. - : Wiley. - 0885-3185 .- 1531-8257. ; 20:10, s. 1345-1349
  • Tidskriftsartikel (refereegranskat)abstract
    • Neuronal intranuclear inclusion disease (NIID) is a rare neurodegenerative disorder with a heterogeneous clinical picture characterized by the presence of eosinophilic intranuclear inclusions in neuronal and glial cells. We describe a case, reported 12 years ago as dopa-responsive dystonia (DRD) with Lewy body pathology. Pathological re-examination has led to a revised diagnosis of neuronal intranuclear inclusion disease. This rare condition, which may be diagnosed in life with a full thickness rectal biopsy, needs to be considered in the differential diagnosis of any case presenting as progressive juvenile parkinsonism (JP) or dystonia. © 2005 Movement Disorder Society.

  • PBB3 Imaging in Parkinsonian disorders: Evidence for binding to abnormally aggregated proteins in addition to tau proteins
  • 2017
  • Ingår i: Movement Disorders. - : John Wiley & Sons Inc.. - 1531-8257 .- 0885-3185. ; 32:Suppl 2, s. 585-587

    • Objective: To study selective regional binding for tau pathology in vivo, using PET with [11C]PBB3 ([11C]methylamino pyridin-3-yl buta-1,3-dienyl benzo[d]thiazol-6-ol) in tauopathies, and in conditions not typically associated with tauopathy. Background: Tau imaging is a promising tool to study the link between tau and neurodegeneration. The specificity of tracers in vivo however remains uncertain, and off target binding is frequently present, limiting its use in parkinsonian disorders. Methods: Dynamic PET scans were obtained for 70 min after the bolus injection of [11C]PBB3 (mean dose 518.97MBq) in five PSP subjects, 1 subject with DCTN1 mutation and PSP phenotype,3 asymptomatic SNCA duplication carriers, 1 MSA subject, and 7 healthy controls of similar age. The occipital cortex was used as reference region for the PSP , the DCTN1 mutation and the MSA subjects. The cerebellar white matter was used as a reference region for the SNCA duplication carriers. Tissue reference Logan analysis was applied to each region of interest (ROI) using the appropriate reference region. Results: In PSP subjects, the highest retention of [11C]PBB3 was observed in putamen, midbrain, globus pallidus and substantia nigra. Longer disease duration and more advanced clinical severity were generally associated with higher tracer retention. The DCTN1/PSP phenotype case showed increased binding in putamen, parietal lobe, and globus pallidus. In SNCA duplication carriers there was a significant increase of [11C] PBB3 binding compared to controls in globus pallidus, putamen, thalamus, ventral striatum, substantia nigra, and pedunculopontine nucleus. The MSA case showed increased binding in comparison to the control group in frontal lobe, globus pallidus, midbrain, parietal lobe, putamen, temporal lobe, substantia nigra, thalamus and ventral striatum. Conclusions: All PSP patients showed increased retention of the tracer in the basal ganglia, as clinically expected. However, binding was also present in asymptomatic SNCA duplication carriers as well as the subject with MSA, which are not typically associated with pathological tau deposition. This suggests the possibility that [11C]PBB3 binds to alpha-synuclein or other proteins involved in neurodegeneration.

  • Alcohol Consumption and Risk of Parkinson's Disease : Data from a Large Prospective European Cohort
  • 2020
  • Ingår i: Movement Disorders. - : John Wiley & Sons Inc.. - 0885-3185 .- 1531-8257. ; 35:7, s. 1258-1263
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Parkinson's disease (PD) etiology is not well understood. Reported inverse associations with smoking and coffee consumption prompted the investigation of alcohol consumption as a risk factor, for which evidence is inconclusive. Objective: To assess the associations between alcohol consumption and PD risk. Methods: Within NeuroEPIC4PD, a prospective European population-based cohort, 694 incident PD cases were ascertained from 209,998 PD-free participants. Average alcohol consumption at different time points was self-reported at recruitment. Cox regression hazard ratios were estimated for alcohol consumption and PD occurrence. Results: No associations between baseline or lifetime total alcohol consumption and PD risk were observed. Men with moderate lifetime consumption (5–29.9 g/day) were at ~50% higher risk compared with light consumption (0.1–4.9 g/day), but no linear exposure–response trend was observed. Analyses by beverage type also revealed no associations with PD. Conclusion: Our data reinforce previous findings from prospective studies showing no association between alcohol consumption and PD risk.
