Question: What is the main component of the Lewy bodies?

Context:
α-syn is the main component of Lewy bodies in Parkinson's disease (PD) and Lewy body dementia
Parkinson's disease (PD) is one of the most common neurodegenerative diseases. Majority of PD are sporadic, for which genetic causes remain largely unknown. Alpha-synuclein, the main component of Lewy bodies, plays a central role in the PD pathogenesis
Parkinson's disease (PD) is characterized by the progressive degeneration of substantia nigra pars compacta (SNpc) dopaminergic neurones and the formation of Lewy bodies (LB) in a proportion of the remaining neurones. α-synuclein is the main component of LB, but the pathological mechanisms that lead to neurodegeneration associated with LB formation remain unclear
α-Synuclein is the main component of Lewy bodies, the intraneuronal inclusion bodies characteristic of Parkinson's disease
Parkinson's disease (PD) is the second most common neurodegenerative disease. The majority of PD cases are sporadic, for which genetic causes and underlying molecular mechanisms remain largely unclear. Autophagy, a highly conserved cellular process that governs the breakdown of long-lived proteins and organelles, has been involved in the degradation of α-synuclein (α-Syn), the main component of Lewy bodies
The main component of Lewy bodies is alpha-synuclein
Alpha-synuclein, a main component of Lewy bodies in synucleinopathies and senile plaques in Alzheimer disease, is centrally involved in neurodegeneration
alpha-Synuclein, the main component of LBs, is expressed as two main isoforms (112 and 140), but little is known about their differential expression in the brain. 
Amyloid precursor protein (APP) is involved in the accumulation of alpha-synuclein, the main component of Lewy bodies
The pre-synaptic protein alpha-synuclein is the main component of Lewy bodies and Lewy neurites, the defining neuropathological characteristics of Parkinson's disease and dementia with Lewy bodies.
Specifically, identification of Lewy bodies in fetal mesencephalic neurons transplanted in patients with Parkinson's disease raised the hypothesis that α-synuclein, the main component of Lewy bodies, could be transmitted from the host brain to a graft of healthy neurons.
LBD has neuropathological characteristics whereby numerous Lewy bodies are present in the central and sympathetic nervous systems, and it is a type of alpha-synucleinopathy because the main component of Lewy body is alpha-synuclein.
In Parkinson's disease, the inclusion bodies are referred to as Lewy bodies and their main component is alpha-synuclein.
The main component of Lewy bodies is alpha-synuclein.
The main component of Lewy bodies is alpha-synuclein (AS).
Amyloid precursor protein (APP) is involved in the accumulation of alpha-synuclein, the main component of Lewy bodies.
Alpha-synuclein, a main component of Lewy bodies in synucleinopathies and senile plaques in Alzheimer disease, is centrally involved in neurodegeneration.
�-Synuclein is the main component of Lewy bodies, the intraneuronal inclusion bodies characteristic of Parkinsons disease.
In the 1990s, �-synuclein was identified as the main constituent of the Lewy pathology, and its aggregation was shown to be central to PD, dementia with Lewy bodies, and multiple system atrophy.
Identification of protein interfaces between �-synuclein, the principal component of Lewy bodies in Parkinson disease, and the molecular chaperones human Hsc70 and the yeast Ssa1p.
Fibrillar �-synuclein (�-Syn) is the principal component of Lewy bodies, which are evident in individuals affected by Parkinson disease (PD).
�-Synuclein is a major component of Lewy bodies in Parkinson disease (PD) and dementia with Lewy bodies (DLB).
The main component of Lewy bodies is alpha-synuclein.
In Parkinson's disease, the inclusion bodies are referred to as Lewy bodies and their main component is alpha-synuclein.
Specifically, identification of Lewy bodies in fetal mesencephalic neurons transplanted in patients with Parkinson's disease raised the hypothesis that Î±-synuclein, the main component of Lewy bodies, could be transmitted from the host brain to a graft of healthy neurons.
alpha-Synuclein, the main component of LBs, is expressed as two main isoforms (112 and 140), but little is known about their differential expression in the brain.
In Parkinson's disease and Lewy body dementia, alpha-synuclein is the main component of Lewy bodies and dystrophic neurites; alpha-synuclein also accumulates in the cytoplasm of glial cells
In Parkinson's disease, the inclusion bodies are referred to as Lewy bodies and their main component is alpha-synuclein
The main component of Lewy bodies is alpha-synuclein (AS)
