Alpha Synuclein Overexpressing Neurons plays an important role in the study of neurodegenerative diseases. This page provides comprehensive information about this topic, including its mechanisms, significance in disease processes, and therapeutic implications.
Neurons containing alpha-synuclein (α-syn) aggregates represent a pathological hallmark of Parkinson's disease (PD) and related synucleinopathies. These neurons develop Lewy bodies and Lewy neurites, leading to cellular dysfunction and death.
- Synaptic protein: Localizes to presynaptic terminals
- Vesicle trafficking: Regulates synaptic vesicle pool
- Neurotransmitter release: Modulates dopamine release
- Protein folding: Normally exists as intrinsically disordered monomer
- Misfolding: Normal α-syn converts to beta-sheet conformation
- Oligomerization: Toxic oligomers form as intermediates
- Fibrillization: Fibrils accumulate in Lewy bodies
- Propagation: Seeds spread between neurons (prion-like)
- Highest vulnerability to α-syn toxicity
- High oxidative stress promotes aggregation
- Mitochondrial complex I deficiency exacerbates
- Cortical Lewy bodies correlate with dementia
- Early involvement in PD with dementia (PDD)
- Contribution to neuropsychiatric symptoms
- Enteric nervous system early affected
- Olfactory bulb neurons show early pathology
- Autonomic ganglia degenerate
- Oligomer toxicity: Soluble oligomers disrupt membranes
- ER stress: Protein misfolding activates unfolded protein response
- Mitochondrial dysfunction: Oligomers impair mitochondrial quality
- Synaptic failure: Presynaptic deficits precede neurodegeneration
- Trans-synaptic spread: Via synaptic connections
- Exosome release: Extracellular vesicles carry seeds
- Microglial activation: Inflammation spreads pathology
- Immunotherapies: Active and passive vaccination trials
- Small molecule inhibitors: Targeting oligomerization
- Gene therapy: ASO targeting SNCA expression
- Protein clearance: Enhancing autophagy-lysosomal pathway
