My understanding is that the answer is "yes". From my 2nd link: "... these findings were not seen in a-synuclein-null animals, consistent with the need for host a-synuclein to participate in permissive templating (or the prion conformer reaction) to sustain a prion-like chain reaction."

Yes, that's right, I broke into my piggybank and spent some money!
