Alpha-synuclein effects on dopaminergic neurons: Protection or damage?
Alpha-synuclein is a principal component of Lewy bodies and Lewy neurites, which are pathologic hall-marks of Parkinson's disease. Alpha-synuclein is generally considered to play a role in synaptic activity, although its function remains largely unknown. Accumulative evidence has been shown that aggregated extracellular alpha-synuclein fibrils can be internalized in the cells and enhance the intracellular formation of protein inclusions, leading to cell death. Conversely, there is emerging evidence suggesting that alpha-synuclein has also neuroprotective effects. In one ...
