“…Individuals with PD suffer from tremors and impaired posture and movement [172,176]. Genetic risk factors have been identified, such as mutations and/or duplication events in the α-synuclein (SNCA) gene [177]. Of all the neurodegenerative diseases discussed, how dysregulation of PcG and TrxG proteins might contribute to PD pathology is the least studied and understood.…”

“…Es existieren zahlreiche Hinweise darauf, dass der neurodegenerative Prozess an den Axonterminalen beginnt, an denen sich auch physiologisch ungefaltetes, monomeres Synuklein befindet, das an der Exozytose präsynaptischer Vesikel beteiligt ist [40]. Beim IPS kommt es, ausgehend von den Axonterminalen, zu einer retrograden Degeneration, und es wird diskutiert, ob die Lewy-Pathologie im Rahmen eines Detoxifizierungsprozess ein Epiphänomen und somit nur einen indirekten Marker der Degeneration darstellt [41,42]. Damit korrelierend gehen neuere Arbeiten davon aus, das bereits 50-60% der nigrostriatalen Axonterminalen, aber nur etwa 30% der dopaminergen Neurone der SN degeneriert sind, wenn erste motorische Symptome in Erscheinung treten [43].…”

“…The discoveries of the causative genes of various fPDs (PARKs) have greatly contributed to investigation into the molecular mechanism of sPD. Based on the information obtained from postmortem brains from fPD patients and fPD-derived iPS cells, DA oxidation, oxidative/endoplasmic reticulum (ER) stress, aggregation of toxic misfolded α-synuclein oligomers, mitochondrial dysfunction, alterations in the ubiquitin-proteasome and autophagy-lysosome systems, and neuroinflammation are assumed to be a central mechanism resulting in neurodegeneration, as described below in more detail (Burbulla et al 2017;Chen et al 2015;Sánchez-Danés et al 2012;Woodard et al 2014;Riederer et al 2019). DA and α-synuclein protein oligomers (causative protein of autosomal dominant fPD type 1/4; PARK1/4; Polymeropoulos et al 1997) are assumed to be key molecules for neurodegeneration in PD.…”
