Aggregation of alpha synuclein has strong implications in Parkinson's disease.
The heterogeneity of folding/aggregation landscape and transient nature of the
early intermediates result in difficulty in developing a successful therapeutic
intervention. Here we used fluorescence measurements at ensemble and single
molecule resolution to study how the late and early events of alpha synuclein
aggregation modulate each other. In-vitro aggregation data was complemented using
measurements inside live neuroblastoma cells by employing a small molecule
labeling technique. An inhibitor molecule (arginine), which delayed the late
event of amyloidosis, was found to bind to the protein, shifting the early
conformational fluctuations towards a compact state. In contrast, a facilitator
of late aggregation (glutamate), was found to be excluded from the protein
surface. The presence of glutamate was found to speed up the oligomer formation
at the early stage. We found that the effects of the inhibitor and facilitator
were additive and as a result they maintained a ratio at which they cancelled
each other's influence on different stages of alpha synuclein aggregation.
