Alpha-synuclein (also α-synuclein) is a protein whose functi furthermore, alpha-synuclein is the primary structural component of lewy bodies, suggesting that protein aggregation plays a role in sporadic parkinson's disease as well.
Role of pink1 in synuclein aggregation
There seem to be various causes of parkinson's disease (pd), yet the pathogenesis of this disease appears to be converging on common themes—oxidative stress, mitochondrial dysfunction, and protein aggregation—all of which are tightly linked to autophagy, a highly conserved cellular homeostatic process essential for bulk degradation of.
- Pink1 defect causes mitochondrial dysfunction, proteasomal deficit and a-synuclein aggregation in cell culture models of parkinson's disease the funders had no role in study design, data collection and analysis.
- Pink1 defect causes mitochondrial dysfunction, proteasomal deficit and -synuclein aggregation in cell culture models of parkinson's disease.
- Alpha-synuclein induced mitochondrial aberrations in a genetic cell culture model of but the role of α-synuclein protein in the pathogenesis is incompletely understood conformational aberration which leads to intracellular aggregation of α-synuclein.
- Studies support the notion of neuroprotective roles for pink1, as it protects cells from damage-induced mitochondrial dysfunction 2 4 minami et al: α-synuclein aggregation is a key pathological feature of the degenerating brain α-syn oligomers in lbd.
- Snca (α-synuclein) misfolding and aggregation is strongly associated with both idiopathic and familial forms of parkinson disease (pd) evidence suggests that snca has an impact on cell clearance routes and protein quality control systems such as the ubiquitin-proteasome system (ups) and autophagy.
