"Our results indicate that alpha-synuclein does not readily traverse any biological lipid membrane, but that there most likely are required proteins that regulate the transport, possibly with some degree of specificity. This is good news for future attempts to develop treatments that prevent transport of synuclein across membranes, as proteins provide better drug targets than do lipid membrane constituents," concludes Dr. Grey.

Could these proteins be the ones from the other article?........dyesin,myosin, and kinesin.

these are transport proteins, one of which when malfunctioing impairs gait . just speculating because they have also said lewy bodies are not the primary cause of cell death.
