The toxic properties of alpha-synuclein are conserved from yeast to man, but the precise underpinnings of the cellular pathologies associated are still elusive, complicating the development of effective therapeutic strategies. Combining molecular genetics with target-based approaches, we established that glycation, an unavoidable age-associated post-translational modification, enhanced alpha-synuclein toxicity in vitro and in vivo, in Drosophila and in mice. Glycation affected primarily the N-terminal region of alpha-synuclein, reducing membrane binding, impaired the clearance of alpha-synuclein, and promoted the accumulation of toxic oligomers that impaired neuronal synaptic transmission. Strikingly, using glycation inhibitors, we demonstrated that normal clearance of alpha-synuclein was re-established, aggregation was reduced, and motor phenotypes in Drosophila were alleviated. Altogether, our study demonstrates glycation constitutes a novel drug target that can be explored in synucleinopathies as well as in other neurodegenerative conditions."],["dc.identifier.doi","10.1093/brain/awx056"],["dc.identifier.isi","000400069900026"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/42703"],["dc.notes.status","zu prĂĽfen"],["dc.notes.submitter","PUB_WoS_Import"],["dc.publisher","Oxford Univ Press"],["dc.relation.haserratum","/handle/2/103764"],["dc.relation.issn","1460-2156"],["dc.relation.issn","0006-8950"],["dc.title","Glycation potentiates alpha-synuclein-associated neurodegeneration in synucleinopathies"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Furthermore, mutations in the gene encoding for ASYN are associated with familial and sporadic forms of PD, suggesting this protein plays a central role in the disease. However, the precise contribution of ASYN to neuronal dysfunction and death is unclear. There is intense debate about the nature of the toxic species of ASYN and little is known about the molecular determinants of oligomerization and aggregation of ASYN in the cell. In order to clarify the effects of different mutations on the propensity of ASYN to oligomerize and aggregate, we assembled a panel of 19 ASYN variants and compared their behaviour. We found that familial mutants linked to PD (A30P, E46K, H50Q, G51D and A53T) exhibited identical propensities to oligomerize in living cells, but had distinct abilities to form inclusions. While the A30P mutant reduced the percentage of cells with inclusions, the E46K mutant had the opposite effect. Interestingly, artificial proline mutants designed to interfere with the helical structure of the N-terminal domain, showed increased propensity to form oligomeric species rather than inclusions. Moreover, lysine substitution mutants increased oligomerization and altered the pattern of aggregation. Altogether, our data shed light into the molecular effects of ASYN mutations in a cellular context, and established a common ground for the study of genetic and pharmacological modulators of the aggregation process, opening new perspectives for therapeutic intervention in PD and other synucleinopathies."],["dc.identifier.doi","10.1371/journal.pgen.1004741"],["dc.identifier.gro","3142024"],["dc.identifier.isi","000345455200011"],["dc.identifier.pmid","25393002"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/11136"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/3701"],["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.eissn","1553-7404"],["dc.relation.issn","1553-7390"],["dc.rights","CC BY 3.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/3.0"],["dc.title","Systematic Comparison of the Effects of Alpha-synuclein Mutations on Its Oligomerization and Aggregation"],["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"]]

However, so far pharmacological BACE1 inhibition failed to rescue the cognitive decline in mild-to-moderate AD patients, which indicates that treatment at the symptomatic stage might be too late. In the current study, chronic in vivo two-photon microscopy was performed in a transgenic AD model to monitor the impact of pharmacological BACE1 inhibition on early β-amyloid pathology. The longitudinal approach allowed to assess the kinetics of individual plaques and associated presynaptic pathology, before and throughout treatment. BACE1 inhibition could not halt but slow down progressive β-amyloid deposition and associated synaptic pathology. Notably, the data revealed that the initial process of plaque formation, rather than the subsequent phase of gradual plaque growth, is most sensitive to BACE1 inhibition. This finding of particular susceptibility of plaque formation has profound implications to achieve optimal therapeutic efficacy for the prospective treatment of AD."],["dc.identifier.doi","10.1007/s00401-017-1804-9"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/12860"],["dc.language.iso","en"],["dc.notes.intern","GRO-Li-Import"],["dc.notes.status","final"],["dc.relation.doi","10.1007/s00401-017-1804-9"],["dc.relation.issn","0001-6322"],["dc.relation.issn","1432-0533"],["dc.title","BACE1 inhibition more effectively suppresses initiation than progression of β-amyloid pathology"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]
