Adenoviral delivery of the mammalian caspase inhibitor X-chromosome-linked inhibitor of apoptosis (Ad.XIAP) to the ON stump leads to expression exclusively in RGCs and rescues 18.9% of the RGCs that would degenerate without treatment. Following adenoviral vector injection into the vitreous body, bioactive glial cell line-derived neurotrophic factor (Ad.GDNF) is expressed in the retina and secreted to rescue 22.8% of lesioned RGCs. Here we report that coadministration of Ad.XIAP retrogradely directed to RGCs and intravitreal Ad.GDNF acts synergistically to protect axotomized RGCs. Combination treatment rescued 47.3% of RGCs that would undergo apoptosis without any treatment as opposed to 37.4% that would be expected if the two treatments acted independently. While without treatment only 15% of axotomized RGCs would survive, combination treatment resulted in survival of 55.4% of the total RGC population. These findings underline the neuroprotective potential of synergistic effects of a combination of different treatment strategies.

The G2019S-LRRK2 mutation is located in the kinase domain of the protein, and has consistently been reported to promote a gain of kinase function. Several proteins have been reported as LRRK2 substrates and/or interactors, suggesting possible pathways involved in neurodegeneration in PD. Hyperphosphorylated Tau protein accumulates in neurofibrillary tangles, a typical pathological hallmark in Alzheimer's disease and frontotemporal dementia. In addition, it is also frequently found in the brains of PD patients. Although LRRK2 is a kinase, it appears that a putative interaction with Tau is phosphorylation-independent. However, the underlying mechanisms and the cellular consequences of this interaction are still unclear. In this study, we demonstrate an interaction between LRRK2 and Tau and that LRRK2 promotes the accumulation of non-monomeric and high-molecular weight (HMW) Tau species independent of its kinase activity. Interestingly, we found that LRRK2 increases Tau secretion, possibly as a consequence of an impairment of Tau proteasomal degradation. Our data highlight a mechanism through which LRRK2 regulates intracellular Tau levels, contributing to the progression of the pathology caused by the LRRK2-mediated proteasome impairment.

The \"alarmin\" HMGB1 is upregulated in muscle inflammation. Its receptor RAGE is crucial for S-amyloid-associated neurodegeneration. Relevant signaling via HMGB1/RAGE is expected in IBM pathology. By real-time-PCR, mRNA-expression levels of HMGB1 and RAGE were upregulated in muscle biopsies of patients with IBM and PM, but not in muscular dystrophy or non-myopathic controls. By immunohistochemistry, both molecules displayed the highest signal in IBM, where they distinctly co-localized to intra-fiber accumulations of beta-amyloid and neurofilament/tau. In these fibers, identification of phosphorylated Erk suggested that relevant downstream activation is present upon HMGB1 signaling via RAGE. Protein expressions of HMGB1, RAGE, Erk and phosphorylated Erk were confirmed by Western blot. In a well established cell-culture model for pro-inflammatory cell-stress, exposure of human muscle-cells to 1L-1 beta + IFN-gamma induced cytoplasmic translocation of HMGB1 and subsequent release as evidenced by ELISA. Upregulation of RAGE on the cell surface was demonstrated by immunocytochemistry and flow-cytometry. Recombinant HMGB1 was equally potent as IL-1 beta + IFN-gamma in causing amyloid-accumulation and cell-death, and both were abrogated by the HMGB1-blocker BoxA.

Here, we performed an exploratory cross-sectional, case-control study aimed at determining whether gene expression differences in peripheral blood may be used as a signature of Parkinson's disease (PD) progression, thereby shedding light into potential molecular mechanisms underlying disease development. We compared transcriptional profiles in the blood from 34 PD patients who developed postural instability within ten years with those of 33 patients who did not develop postural instability within this time frame. Our study identified >200 differentially expressed genes between the two groups. The expression of several of the genes identified was previously found deregulated in animal models of PD and in PD patients. Relevant genes were selected for validation by real-time PCR in a subset of patients. The genes validated were linked to nucleic acid metabolism, mitochondria, immune response and intracellular-transport. Interestingly, we also found deregulation of these genes in a dopaminergic cell model of PD, a simple paradigm that can now be used to further dissect the role of these molecular players on dopaminergic cell loss. Altogether, our study provides preliminary evidence that expression changes in specific groups of genes and pathways, detected in peripheral blood samples, may be correlated with differential PD progression. Our exploratory study suggests that peripheral gene expression profiling may prove valuable for assisting in prediction of PD prognosis, and identifies novel culprits possibly involved in dopaminergic cell death.

Wild-type (WT) and mice with A30P asyn overexpression were treated subacutely with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MFTP), and the number of cholinergic cells in their nucleus basalis magnocellularis-substantia innominata (NBM-SI), their cortical fiber density and their expression of different genes 1 day or 90 days after the last MPTP-injection were measured.

While the function of aSyn is thought to be related to vesicle binding and trafficking, the precise molecular mechanisms linking aSyn with synucleinopathies are still obscure. aSyn can spread in a prion-like manner between interconnected neurons, contributing to the propagation of the pathology and to the progressive nature of synucleinopathies. Here, we investigated the interaction of aSyn with membranes and trafficking machinery pathways using cellular models of PD that are amenable to detailed molecular analyses. We found that different species of aSyn can enter cells and form high molecular weight species, and that membrane binding properties are important for the internalization of aSyn. Once internalized, aSyn accumulates in intracellular inclusions. Interestingly, we found that internalization is blocked in the presence of dynamin inhibitors (blocked membrane scission), suggesting the involvement of the endocytic pathway in the internalization of aSyn. By screening a pool of small Rab-GTPase proteins (Rabs) which regulate membrane trafficking, we found that internalized aSyn partially colocalized with Rab5A and Rab7. Initially, aSyn accumulated in Rab4A-labelled vesicles and, at later stages, it reached the autophagy-lysosomal pathway (ALP) where it gets degraded. In total, our study emphasizes the importance of membrane binding, not only as part of the normal function but also as an important step in the internalization and subsequent accumulation of aSyn. Importantly, we identified a fundamental role for Rab proteins in the modulation of aSyn processing, clearance and spreading, suggesting that targeting Rab proteins may hold important therapeutic value in PD and other synucleinopathies."],["dc.identifier.doi","10.1186/s40478-018-0578-1"],["dc.identifier.pmid","30107856"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/15309"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59304"],["dc.identifier.url","https://sfb1190.med.uni-goettingen.de/production/literature/publications/98"],["dc.identifier.url","https://sfb1286.uni-goettingen.de/literature/publications/36"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation","SFB 1190: Transportmaschinen und Kontaktstellen zellulärer Kompartimente"],["dc.relation","SFB 1190 | P02: Charakterisierung der ER-Mitochondrien-Kontakte und ihre Rolle in der Signalweiterleitung"],["dc.relation","SFB 1286: Quantitative Synaptologie"],["dc.relation","SFB 1286 | B08: Definition von Kaskaden molekularer Veränderungen bei Synucleinopathien während der Neurodegeneration"],["dc.relation.workinggroup","RG Milosevic (Synaptic Vesicle Dynamics)"],["dc.relation.workinggroup","RG Outeiro (Experimental Neurodegeneration)"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","Membrane binding, internalization, and sorting of alpha-synuclein in the cell"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
