Over 3 menstrual cycles, tDCS with 2 mA intensity and 20 min duration was applied to the visual cortex of the patients, in 5 consecutive sessions 1-5 days prior to the first day of their menstruation. The primary endpoint of the study was the frequency of the migraine attacks at the end of the treatment period, however, additional parameters, such as the number of migraine related days and the intensity of pain were also recorded 3 months before, during and 3 months post-treatment Visual cortex excitability was determined by measuring the phosphene thresholds (PTs) using single pulse transcranial magnetic stimulation (TMS) over the visual cortex. Sixteen patients completed the study. A significant decrease in the number of migraine attacks (p = 0.04) was found in the cathodal group compared to baseline but not compared to sham (p = 0.053). In parallel the PTs increased significantly in this group, compared to the sham group (p < 0.05). Our results indicate that prophylactic treatment with rctDCS over the visual cortex might be able to decrease the number of attacks in patients with menstrual migraine, probably by modifying cortical excitability.

The effects depend on receptor subtypes, affinity, concentration level, and the kind of neuroplasticity induced. In animal experiments, dopamine D-2-like receptor stimulation revealed partially antagonistic effects on plasticity, which might be explained by dosage dependency. In humans, D-2 receptor block abolishes plasticity, and the D-2/D-3, but predominantly D-3, receptor agonist ropinirol has a dosage-dependent nonlinear affect on plasticity. Here we aimed to determine the specific affect of D-2 receptor activation on neuroplasticity in humans, because physiological effects of D-2 and D-3 receptors might differ. Therefore, we combined application of the selective D-2 receptor agonist bromocriptine (2.5, 10, and 20 mg or placebo medication) with anodal and cathodal transcranial direct current stimulation (tDCS), which induces nonfocal plasticity, and with paired associative stimulation (PAS) generating a more focal kind of plasticity in the motor cortex of healthy humans. Plasticity was monitored by transcranial magnetic stimulation-induced motor-evoked potential amplitudes. For facilitatory tDCS, bromocriptine prevented plasticity induction independent from drug dosage. However, its application resulted in an inverted U-shaped dose-response curve on inhibitory tDCS, excitability-diminishing PAS, and to a minor degree on excitability-enhancing PAS. These data support the assumption that modulation of D-2-like receptor activity exerts a nonlinear dose-dependent effect on neuroplasticity in the human motor cortex that differs from predominantly D-3 receptor activation and that the kind of plasticity-induction procedure is relevant for its specific impact."],["dc.description.sponsorship","German Research Foundation [NI 683/6-1]"],["dc.identifier.doi","10.1523/JNEUROSCI.0832-14.2014"],["dc.identifier.isi","000341017300023"],["dc.identifier.pmid","25100602"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/32687"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Soc Neuroscience"],["dc.relation.issn","0270-6474"],["dc.title","Dosage-Dependent Effect of Dopamine D-2 Receptor Activation on Motor Cortex Plasticity in Humans"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

In preparation for future clinical trials, we performed a preclinical characterization of a pegylated derivative of granulocyte colony-stimulating factor (pegfilgrastim) in the mouse 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine model of Parkinson's disease. We determined serum and cerebrospinal fluid drug levels after subcutaneous injection. A single injection of pegfilgrastim was shown to achieve stable levels of granulocyte colony-stimulating factor in both serum and cerebrospinal fluid with substantially higher levels compared to repetitive filgrastim injections. Leucocyte blood counts were only transiently increased after repeated injections. We demonstrated substantial dose-dependent long-term neuroprotection by pegfilgrastim in both young and aged mice, using bodyweight-adjusted doses that are applicable in clinical settings. Importantly, we found evidence for the functionally relevant preservation of nigrostriatal projections by pegfilgrastim in our model of Parkinson's disease, which resulted in improved motor performance. The more stable levels of pegylated neuroprotective proteins in serum and cerebrospinal fluid may represent a general advantage in the treatment of chronic neurodegenerative diseases and the resulting longer injection intervals are likely to improve patient compliance. In summary, we found that pegylation of a neuroprotective growth factor improved its pharmacokinetic profile over its non-modified counterpart in an in vivo model of Parkinson's disease. As the clinical safety profile of pegfilgrastim is already established, these data suggest that evaluation of pegfilgrastim in further Parkinson's disease models and ultimately clinical feasibility studies are warranted."],["dc.identifier.doi","10.1093/brain/aws054"],["dc.identifier.gro","3142529"],["dc.identifier.isi","000304538900022"],["dc.identifier.pmid","22427327"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8890"],["dc.language.iso","en"],["dc.notes.intern","WoS Import 2017-03-10 / Funder: Michael J.

Methods: We combined an automated wheel-running paradigm with low-dose botulinum toxin injections into the calf muscles of wild-type mice. Half of the mice were injected either before the nightly running or before the daily resting period. Results: After botulinum toxin injections, running distance and maximum velocity decreased dose-dependently. The degree and duration of decrease between the respective groups with regard to the time-points of injection were identical. Conclusions: This in vivo paradigm quantifies the degree of otherwise clinically inapparent botulinum toxin-induced focal calf muscle paresis. Increased muscle activity after low-dose injections does not influence the efficacy of botulinum toxin in normal muscles.

Moreover, preterm infants exhibit deficits in motor coordination and balance. Based on clinical data, higher oxygen levels in preterm infants lead to worse neurological outcome, and experimental hyperoxia causes wide-ranging cerebral changes in neonatal rodents. We hypothesize that hyperoxia in the immature brain may affect motor activity in preterm infants. We subjected newborn mice from P6 to P8 to 48 h of hyperoxia (80% O-2) and tested motor activity in running wheels starting at adolescent age P30. Subsequently, from P44 to P53, regular wheels were replaced by complex wheels with variable crossbar positions to assess motor coordination deficits. MRI with diffusion tensor imaging was performed in the corpus callosum to determine white matter diffusivity in mice after hyperoxia at ages P30 and P53 in comparison to control animals. Adolescent mice after neonatal hyperoxia revealed significantly higher values for maximum velocity and mean velocity in regular wheels than controls (P<0.05). In the complex running wheels, however, maximum velocity was decreased in animals after hyperoxia, as compared to controls (P<0.05). Decreased fractional anisotropy and increased radial diffusion coefficient were observed in the corpus callosum of P30 and P53 mice after neonatal hyperoxia compared to control mice.
