To obtain insight into the function different aggregated alpha S species have in neurotoxicity in vivo, we generated alpha S variants by a structure-based rational design. Biophysical analysis revealed that the alpha S mutants have a reduced fibrillization propensity, but form increased amounts of soluble oligomers. To assess their biological response in vivo, we studied the effects of the biophysically defined pre-fibrillar alpha S mutants after expression in tissue culture cells, in mammalian neurons and in PD model organisms, such as Caenorhabditis elegans and Drosophila melanogaster. The results show a striking correlation between alpha S aggregates with impaired beta-structure, neuronal toxicity and behavioural defects, and they establish a tight link between the biophysical properties of multimeric aS species and their in vivo function.
