Histopathological and radiological analysis revealed that neurodegeneration occurs early in the disease course. However, the pathological mechanisms involved in neurodegeneration are poorly understood. Myelin oligodendrocyte glycoprotein (MOG)-induced experimental autoimmune encephalomyelitis (EAE) in Brown Norway rats (BN-rats) is a well-established animal model, especially of the neurodegenerative aspects of MS. Previous studies in this animal model indicated that loss of retinal ganglion cells (RGCs), the neurons that form the axons of the optic nerve, occurs in the preclinical phase of the disease and is in part independent of overt histopathological changes of the optic nerve. Therefore, the aim of this study was to identify genes which are involved in neuronal cell loss at different disease stages of EAE. Furthermore, genes that are highly specific for autoimmune-driven neurodegeneration were compared to those regulated in RGCs after optic nerve axotomy at corresponding time points. Using laser capture micro dissection we isolated RNA from unfixed RGCs and performed global transcriptome analysis of retinal neurons. In total, we detected 582 genes sequentially expressed in the preclinical phase and 1150 genes in the clinical manifest EAE (P < 0.05, fold-induction >1.5). Furthermore, using ingenuity pathway analysis (IPA), we identified amyloid precursor protein (APP) as a potential upstream regulator of changes in gene expression in the preclinical EAE but neither in clinical EAE, nor at any time point after optic nerve transection. Therefore, the gene pathway analysis lead to the hypothesis that altered cleavage of APP in neurons in the preclinical phase of EAE leads to the enhanced production of APP intracellular domain (AICD), which in turn acts as a transcriptional regulator and thereby initiates an apoptotic signaling cascade via up-regulation of the target gene p53."],["dc.description.sponsorship","Open-Access Publikationsfonds 2015"],["dc.format.extent","17"],["dc.identifier.doi","10.1371/journal.pone.0138852"],["dc.identifier.gro","3141819"],["dc.identifier.isi","000362177100023"],["dc.identifier.pmid","26426258"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/12217"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/1423"],["dc.language.iso","en"],["dc.notes.intern","WoS Import 2017-03-10"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.issn","1932-6203"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","Neurodegeneration in Autoimmune Optic Neuritis Is Associated with Altered APP Cleavage in Neurons and Up-Regulation of p53"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

The mechanisms underlying this early axonal degeneration are, however, still poorly understood. Here, we examined the effects of overexpression of human wildtype alpha-synuclein (alpha Syn-WT), a protein associated with PD, and its mutant variants alpha Syn-A30P and -A53T on neurite morphology and functional parameters in rat primary midbrain neurons (PMN). Moreover, axonal degeneration after overexpression of alpha Syn-WT and -A30P was analyzed by live imaging in the rat optic nerve in vivo. We found that overexpression of alpha Syn-WT and of its mutants A30P and A53T impaired neurite outgrowth of PMN and affected neurite branching assessed by Sholl analysis in a variant-dependent manner. Surprisingly, the number of primary neurites per neuron was increased in neurons transfected with alpha Syn. Axonal vesicle transport was examined by live imaging of PMN co-transfected with EGFP-labeled synaptophysin. Overexpression of all alpha Syn variants significantly decreased the number of motile vesicles and decelerated vesicle transport compared with control. Macroautophagic flux in PMN was enhanced by alpha Syn-WT and -A53T but not by alpha Syn-A30P. Correspondingly, colocalization of alpha Syn and the autophagy marker LC3 was reduced for alpha Syn-A30P compared with the other alpha Syn variants. The number of mitochondria colocalizing with LC3 as a marker for mitophagy did not differ among the groups. In the rat optic nerve, both alpha Syn-WT and -A30P accelerated kinetics of acute axonal degeneration following crush lesion as analyzed by in vivo live imaging.

In the present study, we analyzed the involvement of PrPC in different pathological mechanisms underlying AD: the processing of the amyloid-beta protein precursor (A beta PP) and its interaction with A beta PP, tau, and different phosphorylated forms of the tau protein (p-tau). The effect of PrPC on tau expression was investigated in various cellular compartments using a HEK293 cell model expressing a tau mutant (3PO-tau) or wild type (WT)-tau. We could show that PrPC reduces A beta PP cleavage, leading to decreased levels of A beta(40) and sA beta PP without changing the protein expression of A beta PP, beta-secretase, or gamma-secretase. Tau and its phosphorylated forms were identified as interactions partners for PrPC, raising the question as to whether PrPC might also be involved in tau pathology. Overexpression of PrPC in PRNP and 3PO-tau transfected cells resulted in a reduction of 3PO-tau and p-tau as well as a decrease of 3PO-tau-related toxicity. In addition, we used the transgenic PrPC knockout (Prnp0/0) mouse line to study the dynamics of tau phosphorylation, an important pathological hallmark in the pathogenesis of AD in vivo. There, an effect of PrPC on tau expression could be observed under oxidative stress conditions but not during aging. In summary, we provide further evidence for interactions of PrPC with proteins that are known to be the key players in AD pathogenesis.

Whereas iron is known to bind to α‐syn, facilitating its aggregation and regulating α‐syn expression, it remains unclear if and how iron also modulates α‐syn spreading. To elucidate the influence of iron on the propagation of α‐syn pathology, we investigated α‐syn spreading after stereotactic injection of α‐syn preformed fibrils (PFFs) into the striatum of mouse brains after neonatal brain iron enrichment. C57Bl/6J mouse pups received oral gavage with 60, 120, or 240 mg/kg carbonyl iron or vehicle between postnatal days 10 and 17. At 12 weeks of age, intrastriatal injections of 5‐µg PFFs were performed to induce seeding of α‐syn aggregates. At 90 days post‐injection, PFFs‐injected mice displayed long‐term memory deficits, without affection of motor behavior. Interestingly, quantification of α‐syn phosphorylated at S129 showed reduced α‐syn pathology and attenuated spreading to connectome‐specific brain regions after brain iron enrichment. Furthermore, PFFs injection caused intrastriatal microglia accumulation, which was alleviated by iron in a dose‐dependent way. In primary cortical neurons in a microfluidic chamber model in vitro, iron application did not alter trans‐synaptic α‐syn propagation, possibly indicating an involvement of non‐neuronal cells in this process. Our study suggests that α‐syn PFFs may induce cognitive deficits in mice independent of iron. However, a redistribution of α‐syn aggregate pathology and reduction of striatal microglia accumulation in the mouse brain may be mediated via iron‐induced alterations of the brain connectome. image"],["dc.description.abstract","Brain iron accumulation and α‐synuclein (α‐syn) spreading pathology are common pathological findings in Parkinson's disease.

It is plausible that soft vulnerable plaques are more likely to be injured during CAS procedure and are therefore more likely to initiate the cascade finally leading to ISR. The aim of this study was to investigate if plaque morphology detected by a simple applicable Duplex ultrasound score before CAS can be used as a predictor for ISR. Methods: Within a prospectively collected single-centre CAS database of 281 patients (comprising 300 arteries) with high-grade carotid artery stenosis, who underwent CAS between May 2003 and January 2013, we conducted a nested case-control study. Plaque morphology before CAS was analysed by a blinded investigator and each parameter of the Total Plaque Risk Score (TPRS) as well as the whole score was evaluated with regard to its diagnostic validity for ISR. Results: We analysed the data of 10 patients with ISR and 50 patients without ISR. There were no significant differences with respect to baseline characteristics, vascular risk factors, and degree of stenosis between patients with and without ISR. The duration of follow-up was longer in patients with ISR (p = 0.024) and these patients were more likely to show increased PSV (p = 0.012) immediately after CAS than patients without ISR. Neither individual parameters of the TPRS score nor the score as a whole were suitable as a diagnostic test for ISR development. Conclusions: In the present study we could demonstrate that the non-contrast enhanced DUS of the pre-interventional plaque formation cannot be used as a predictor for the development of ISR. Evaluating a more sophisticated, but not routinely available approach e. g. by ultrasound based plaque perfusion imaging or CT based plaque analysis could be helpful in the future in order to assess the role of plaque morphology in the context of ISR development."],["dc.identifier.doi","10.1186/1471-2377-13-163"],["dc.identifier.gro","3142254"],["dc.identifier.isi","000329060500003"],["dc.identifier.pmid","24191865"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/9475"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6243"],["dc.language.iso","en"],["dc.notes.intern","WoS Import 2017-03-10"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.issn","1471-2377"],["dc.rights","CC BY 2.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/2.0"],["dc.title","Plaque morphology detected with Duplex ultrasound before carotid angioplasty and stenting (CAS) is not a predictor of carotid artery in-stent restenosis, a case control study"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Inhibition of axonal degeneration combined with cellular neuroprotection therefore seem key to targeting an early stage in Parkinson's disease progression. Based on our previous studies in traumatic and neurodegenerative disease models, we have identified rho kinase as a molecular target that can be manipulated to disinhibit axonal regeneration and improve survival of lesioned central nervous system neurons. In this study, we examined the neuroprotective potential of pharmacological rho kinase inhibition mediated by fasudil in the in vitro 1-methyl-4-phenylpyridinium cell culture model and in the subchronic in vivo 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine mouse model of Parkinson's disease. Application of fasudil resulted in a significant attenuation of dopaminergic cell loss in both paradigms. Furthermore, dopaminergic terminals were preserved as demonstrated by analysis of neurite network in vitro, striatal fibre density and by neurochemical analysis of the levels of dopamine and its metabolites in the striatum. Behavioural tests demonstrated a clear improvement in motor performance after fasudil treatment. The Akt survival pathway was identified as an important molecular mediator for neuroprotective effects of rho kinase inhibition in our paradigm. We conclude that inhibition of rho kinase using the clinically approved small molecule inhibitor fasudil may be a promising new therapeutic strategy for Parkinson's disease."],["dc.identifier.doi","10.1093/brain/aws254"],["dc.identifier.gro","3142444"],["dc.identifier.isi","000311644800021"],["dc.identifier.pmid","23087045"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/9499"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8352"],["dc.language.iso","en"],["dc.notes.intern","WoS Import 2017-03-10"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.issn","0006-8950"],["dc.rights","CC BY-NC 3.0"],["dc.rights.uri","https://creativecommons.org/licenses/by-nc/3.0"],["dc.title","Inhibition of rho kinase enhances survival of dopaminergic neurons and attenuates axonal loss in a mouse model of Parkinson's disease"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

The only approved drug, riluzole, lacks clinical efficacy so that more potent treatment options are needed. We have identified rho kinase (ROCK) as a target, which can be manipulated to beneficially influence disease progression in models of ALS. Here, we examined the therapeutic potential of the ROCK inhibitor Y-27632 in both an in vitro and in an in vivo paradigm of motoneuron disease. Application of Y-27632 to primary motoneurons in vitro increased survival and promoted neunte outgrowth. In vivo, SOD1G93A mice were orally treated with 2 or 30 mg/kg body weight of Y-27632. The 2 mg/kg group did not benefit from Y-27632 treatment, whereas treatment with 30 mg/kg resulted in improved motor function in male mice. Female mice showed only limited improvement and overall survival was not modified in both 2 and 30 mg/kg Y-27632 groups. In conclusion, we provide evidence that inhibition of ROCK by Y-27632 is neuroprotective in vitro but has limited beneficial effects in vivo being restricted to male mice. Therefore, the evaluation of ROCK inhibitors in preclinical models of ALS should always take gender differences into account."],["dc.format.extent","9"],["dc.identifier.doi","10.3389/fnins.2014.00304"],["dc.identifier.gro","3142033"],["dc.identifier.isi","000346516800001"],["dc.identifier.pmid","25339858"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/11029"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/3801"],["dc.language.iso","en"],["dc.notes.intern","WoS Import 2017-03-10"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.issn","1662-453X"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","The rho kinase inhibitor Y-27632 improves motor performance in male SOD1(G93A) mice"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

The main complications are local swelling and pain, but communication of the inflamed bursa with the joint can occur, leading to subsequent cartilage damage and bone destruction. Case presentation We report a case of a 47-year-old Caucasian woman without rheumatoid arthritis who reported pain and palsy in her left leg almost one year after total hip replacement. She was diagnosed with an ileopectineal bursitis after total hip replacement, leading to femoral nerve palsy. The diagnosis was obtained by thorough clinical examination, the results of focused computed tomography and magnetic resonance imaging. Conclusion To the best of our knowledge, this is the first report of non-infectious ileopectineal bursitis in a patient without rheumatoid arthritis as a complication of total hip replacement. This rare case underlines the importance of proper neurologic examination of persistent conditions after orthopedic intervention in otherwise healthy individuals. We believe this case should be useful for a broad spectrum of medical specialties, including orthopedics, neurology, radiology, and general practice."],["dc.identifier.doi","10.1186/1752-1947-5-190"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/6375"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/12889"],["dc.language.iso","en"],["dc.notes.intern","GRO-Li-Import"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.relation.doi","10.1186/1752-1947-5-190"],["dc.relation.issn","1752-1947"],["dc.relation.issn","1752-1947"],["dc.rights","CC BY 2.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/2.0"],["dc.title","Femoral nerve palsy caused by ileopectineal bursitis after total hip replacement: a case report"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
